Terms of Service

Last updated 19 June 2026

These Terms of Service ("Terms") are a binding agreement between you and Pablo Andrés Sheridan Garza — a Mexican individual operating as a persona física con actividad empresarial (sole proprietor with business activity), resident in Mexico, doing business as "Twenty4" ("Twenty4," "we," "us," or "our"). They govern your access to and use of the Twenty4 mobile application, the Twenty4 website at https://twenty4.app, and the related services we provide (together, the "Service").

Please read these Terms together with our Privacy Policy and, if you are located in Mexico, our Aviso de Privacidad. A list of our specific service providers is available on request — email privacy@twenty4.app.

1. Acceptance of these Terms; eligibility; age

Acceptance. By tapping to agree at sign-up, by creating an account, by signing in, or by otherwise accessing or using the Service, you acknowledge that you have read and understood these Terms and agree to be bound by them and by our Privacy Policy. If you do not agree, do not use the Service.

Capacity. You represent that you have the legal capacity to enter into a binding contract where you live, and that you are not barred from using the Service under any applicable law.

Age. You must be at least 13 years old to use the Service. If the law where you live sets a higher minimum age for consenting to online services on your own (for example, 16 in parts of the European Economic Area), you must meet that higher age, or have the consent of a holder of parental responsibility, as your local law requires. The Service is not directed to children below the applicable minimum age, and we do not knowingly collect personal information from them. By agreeing to these Terms, you affirm that you meet the applicable minimum age. We do not collect your date of birth.

Clickwrap acknowledgement. We record your acceptance of these Terms and of our Privacy Policy at sign-up (and again when we make material changes), including the version accepted and the date. Your continued use of the Service after a non-material change takes effect means you accept it. See Section 24 (Changes to these Terms).

2. The Service, and changes to it

Twenty4 is a private, collaborative journal and timeline. You can write notes and events, attach photos and videos, comment, and invite other people to shared events. Twenty4 is not a public social network: there are no public profiles, no followers, and no public discovery feed. Content you create is private to you unless and until you choose to share it with people you invite.

We are continually improving the Service. We may add, change, suspend, or discontinue any part of the Service — including features, storage tiers, and supported platforms — at any time, with notice where reasonable and required by law. The Service is currently offered primarily on iOS; a web application may follow. Artificial-intelligence features are not yet active (see Section 23 and our Privacy Policy).

3. Your account and your responsibility for security

To use most features you must create an account. Sign-in is available via Sign in with Apple, Google, or email (magic link, or a password if you choose one). We identify your account internally by an opaque identifier and the email address provided by your sign-in method.

You are responsible for:

• safeguarding your account credentials and any device on which you stay signed in;
• all activity that occurs under your account; and
• notifying us promptly at hello@twenty4.app (or privacy@twenty4.app for privacy matters) if you suspect any unauthorized use of your account.

You may not share your account, sell or transfer it, or let anyone else use it to circumvent storage limits or these Terms.

4. Your Content — ownership and the limited license you grant us

You own your content. You retain all intellectual-property rights you already hold in the content you create in Twenty4 — your journal entries, events, notes, titles, tags, locations, photos, videos, comments, messages, and similar material ("Your Content"). We do not claim ownership of Your Content. We do not sell Your Content, and we do not use it for advertising.

The limited license you grant us. So that we can operate the Service, you grant us a limited, non-exclusive, worldwide, royalty-free license to host, store, back up, reproduce, transcode, resize, compress, and display Your Content, and to generate the technical derivatives (such as thumbnails, preview clips, and compressed or display copies) that the Service needs — solely to provide, maintain, secure, and improve the Service for you and for the people you choose to share an event with.

This license:

• is not transferable or sublicensable, except to our service providers (subprocessors) acting on our behalf to run the Service (these providers are described in our Privacy Policy; the specific list is available on request), and except as part of an assignment permitted under Section 19;
• does not grant us the right to publicly perform, broadcast, syndicate, sell, or create non-technical derivative works of Your Content; and
• ends when you delete the relevant content or your account, subject to the short, standard backup-rotation windows and the limited legal-retention obligations described in Section 11 and in our Privacy Policy, and except that copies you have already shared with collaborators may persist in their view until they, or the shared event, are removed.

5. Acceptable use and prohibited content

You agree not to use the Service to create, store, upload, or share content, or to take any action, that:

• is unlawful, fraudulent, or deceptive, or that infringes or misappropriates any third party's intellectual-property, privacy, or other rights;
• you do not have the right to upload or share;
• harasses, threatens, defames, or harms another person;
• constitutes, depicts, promotes, or facilitates child sexual abuse material ("CSAM") or the sexual exploitation of minors, or any other content prohibited by law (see Section 18);
• contains malware or is intended to interfere with, disable, or compromise the Service or any user's data; or
• attempts to break, overload, probe, scrape, reverse-engineer, or gain unauthorized access to the Service, its infrastructure, or another user's data.

We may remove or restrict access to content, and may suspend or terminate accounts, that we reasonably believe violate this Section or the law, or that expose us, our users, or third parties to liability or harm, as described in Section 12 (Termination). We do not proactively monitor or scan Your Content (see Section 17), but we may act on reports and on content that comes to our attention.

6. Sharing and collaboration; release of claims for user-to-user interactions

What collaborators can see. When you invite people to a shared event, they can see and contribute to the content you share in that event — including your display name (or, where no display name is set, the local part of your email address), the photos and videos you add, your comments, and activity such as joins, edits, and media additions. People you invite keep their own content; you do not gain ownership of what collaborators add, and they do not gain ownership of what you add. You can remove collaborators, and removing a collaborator also removes that person's media from the shared event, as described in the app.

You are responsible for what you share. You decide what to share and with whom. Share only content you have the right to share, and remember that other members of a shared event may view, save, screenshot, or re-share what you contribute, outside our control.

Release of claims between users. The Service lets you interact with other users through shared events, comments, and @mentions. To the maximum extent permitted by applicable law, you release us, and our successors and service providers, from any and all claims, demands, damages, and disputes of any kind arising out of or connected with any interaction, dispute, content, conduct, or transaction between you and any other user or collaborator (including disputes over what is shared, who is invited or removed, and content another user contributes). We are not a party to, and have no responsibility for, disputes between users.

7. Subscriptions, storage tiers, and billing

The Service offers a free tier and paid subscription plans:

• Free — 1 GB
• Plus — 25 GB
• Premium — 100 GB
• Pro — 500 GB

A private, invite-only Founder tier exists and is not offered for sale.

• Where you are billed. Paid plans are sold and billed through Apple's App Store (and, for any future web purchases, through our payment provider, Stripe). Apple is the merchant of record for App Store purchases; we never receive or store your payment-card details.
• Auto-renewal (please read). Subscriptions renew automatically at the then-current price for the same period until you cancel. Payment is charged to your Apple ID at confirmation of purchase, and your account is charged for renewal within 24 hours before the current period ends, unless you turn off auto-renew at least 24 hours before the period ends. You can manage or cancel at any time in your App Store account settings (Settings → your name → Subscriptions). Cancellation takes effect at the end of the current billing period.
• Refunds. Refunds for App Store purchases are handled by Apple under Apple's policies — please request them through Apple. We do not control, and cannot guarantee, App Store refund decisions.
• Price changes. If we change subscription prices, we will give you notice and obtain any consent required by the App Store and applicable law before the new price applies to you; Apple's renewal-consent flow governs App Store subscriptions.
• What a subscription buys. Each paid plan increases your storage allowance and unlocks media uploads above the free limit. Storage usage is measured as your total footprint, including content in Recently Deleted until it is permanently purged — so deleting media frees up your allowance only after that content is permanently removed.

8. Free-tier storage limit and data loss after a lapse

We want this to be clear and fair, so please read this section carefully.

• Under 1 GB (free tier). You have full access, including unlimited text entries.
• At or over 1 GB on the free tier. You can keep creating unlimited text entries, but you cannot add new photos or videos until you free up space or upgrade. Your existing content remains available.
• If a paid plan lapses while you are over 1 GB. If your subscription ends while your stored content is above the free limit, you won't be able to add new photos or videos, but your existing content stays available to you for 24 months — we delete nothing during that time. To stay on the free plan, bring your media back under the free limit before then; you can also upgrade again at any time, or export a copy of your content from the app, or contact us. After 24 months, if your media still exceeds the free limit, we may delete your photos and videos — only media is affected; your written entries are always kept.

You agree that we will have no liability to you for any deletion of content carried out under this Section. See Section 12 (no liability for deletion of Your Content).

9. Account inactivity and automatic deletion

To avoid storing data indefinitely, if a free account remains inactive for 4 years, we reserve the right to delete the account and its content. Signing in at any time resets the inactivity clock. "Inactive" means no sign-in.

You agree that we will have no liability to you for any deletion of content carried out under this Section.

10. Deleting your data and your account

You can delete individual content in the app, and you can delete your entire account from within the app at any time. Account deletion is immediate and permanent: it removes Your Content from our database, removes your media from object storage, and removes your authentication record — subject to short, standard backup-rotation windows (after which residual copies in backups are overwritten in the ordinary course) and to limited retention we are required or permitted to keep (for example, financial and billing records we must keep under Mexican fiscal law, and records reasonably needed to comply with law, prevent fraud or abuse, or resolve disputes). Where you signed in with Apple, deleting your account also revokes the associated Sign in with Apple token. For details on what is retained and for how long, see the Privacy Policy.

11. Service availability; no warranties ("as is" / "as available")

We work hard to keep the Service reliable, but the Service is provided "AS IS" and "AS AVAILABLE," without warranties of any kind, whether express, implied, or statutory, including any implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement, to the fullest extent permitted by law.

We do not warrant that the Service will be uninterrupted, timely, secure, or error-free, that defects will be corrected, or that content will never be lost or become unavailable. Please keep your own copies of anything important to you. The Service depends on third-party infrastructure (see Section 20, Force majeure), and we do not warrant the performance of those third parties.

If we discontinue Twenty4. If we ever discontinue Twenty4, we'll give you at least 2 years to export or request a copy of your content before anything is removed.

12. Termination

By you. You may stop using the Service and delete your account at any time (Section 10).

By us. We may suspend or terminate your access to all or part of the Service, with or without cause, where permitted by applicable law, and with or without notice — including if you violate these Terms or the law, if your account is inactive (Section 9), if you exceed your storage allowance after a lapse (Section 8), or to protect the Service, other users, or third parties. Where reasonable and lawful, we will give you notice.

No liability for deletion of Your Content. To the fullest extent permitted by applicable law, we will not be liable to you or to any third party for any suspension or termination of your access, or for any deletion of, or inability to access, Your Content that results from a termination, suspension, account deletion, inactivity deletion, free-tier over-limit removal, or discontinuation of the Service carried out in accordance with these Terms. This Section is the contractual backstop for the deletion behaviors described in Sections 8 (over-limit media removal after a lapse), 9 (inactivity deletion), 10 (account deletion), and 11 (discontinuation of the Service).

Survival. Sections that by their nature should survive termination — including Sections 4 (license wind-down), 6 (release), 11–17, 19–23, and 25 — survive.

13. Disclaimer of warranties

In addition to Section 11, you understand that you use the Service at your own risk. We make no representation or warranty that the Service will meet your requirements, that any content you store will be preserved, or that the Service is free of vulnerabilities, viruses, or harmful components. No advice or information, whether oral or written, that you obtain from us or through the Service creates any warranty not expressly stated in these Terms. Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you.

14. Limitation of liability

To the fullest extent permitted by applicable law:

• No indirect damages. Neither we, nor our service providers, will be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or other intangible losses, arising out of or relating to the Service or these Terms, even if we have been advised of the possibility of such damages.
• Liability cap. Our total aggregate liability for all claims relating to the Service or these Terms will not exceed the greater of (a) the total amounts you paid us for the Service in the twelve (12) months before the event giving rise to the claim, or (b) USD $100.

The USD $100 floor applies because the free tier carries no fees; it ensures a meaningful cap even where you have paid us nothing.

These limitations apply regardless of the legal theory (contract, tort, statute, or otherwise) and form an essential basis of the bargain between you and us.

EEA / UK / Mexico savings clause. Nothing in these Terms excludes or limits our liability where it would be unlawful to do so. This includes liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, and for any other liability that cannot be excluded or limited under the mandatory law of your jurisdiction — including non-waivable consumer-protection rights in the EEA, the United Kingdom, and Mexico (for example, rights under PROFECO-administered consumer law). To the extent any limitation in this Section is held unenforceable as to you, it applies only to the maximum extent permitted, and the remainder of these Terms remains in effect.

15. Indemnification

To the extent permitted by applicable law, you agree to defend, indemnify, and hold harmless Twenty4 (Pablo Andrés Sheridan Garza) and our successors, assigns, and service providers from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or related to: (a) Your Content; (b) your use of the Service; (c) your violation of these Terms; or (d) your violation of any law or any third-party right. We may, at our option, assume the exclusive defense and control of any matter subject to indemnification by you, in which case you will cooperate with us. This Section does not apply to the extent the relevant claim is prohibited from being shifted to a consumer under the mandatory law of your jurisdiction (including in the EEA, the UK, and Mexico).

16. Local-law savings clause (EEA / UK / Mexico and other mandatory law)

These Terms apply to the maximum extent permitted by applicable law. Nothing in these Terms is intended to exclude, restrict, or waive any right or remedy that you have under mandatory law and that cannot lawfully be excluded, restricted, or waived — including the non-waivable consumer-protection rights of consumers in the EEA, the United Kingdom, and Mexico (such as rights administered by PROFECO in Mexico and data-protection rights administered by INAI), and any mandatory rights you have under the consumer law of your place of residence. Where any provision of these Terms conflicts with such a non-waivable right, that right prevails, and the rest of these Terms continues to apply.

17. Government and legal requests; no proactive scanning

No proactive monitoring. We do not proactively monitor, review, or scan Your Content. The only automated processing we apply to Your Content is the technical operation needed to provide the Service (such as transcoding media and generating thumbnails and preview clips).

We are not end-to-end encrypted. Twenty4 protects Your Content with encryption in transit and at rest and with strict server-side access controls (see the Privacy Policy), but Twenty4 is not end-to-end encrypted, and we may be legally compelled to disclose information. We do not claim that we are unable to access Your Content.

How we handle requests. We may access, preserve, or disclose information if we believe in good faith that it is reasonably necessary to: (a) comply with a valid and binding legal request from a competent authority (such as a subpoena, court order, warrant, or other enforceable legal process); (b) respond to an emergency involving a risk of death or serious physical injury; or (c) protect the rights, property, or safety of Twenty4, our users, or the public, or to enforce these Terms. We review each request, object to requests we consider invalid, overbroad, or unlawful, and disclose only the minimum information necessary. Where permitted by law and not prohibited by the request itself, we will make reasonable efforts to notify you before disclosing your information.

18. CSAM and illegal-content prohibition; reporting and removal

CSAM and other content that sexually exploits or endangers minors are strictly prohibited on the Service and have no recovery, grace, or appeal window under these Terms. We will remove such content when we become aware of it, terminate the responsible account, preserve information as required, and report to the appropriate authorities and clearinghouses as required by law.

Reporting. To report CSAM, other illegal content, or abuse on a shared event, contact hello@twenty4.app with enough detail to locate the content. We will review reports and take action we consider appropriate, which may include removing content, restricting features, and suspending or terminating accounts.

19. Assignment and successors

We may assign. We may assign or transfer these Terms, and any of our rights and obligations under them, in whole or in part, at any time and without your consent and without notice — including to a successor entity, or in connection with a merger, reorganization, change of legal form, conversion of the sole proprietorship into a company or other legal entity, sale of assets, or other corporate transaction. You agree that any such assignee or successor may enforce and perform these Terms in our place, and that no re-execution, re-acceptance, or further action by you is required for the assignment or transfer to be effective. We will provide notice of a change in the operating entity where required by applicable law (for example, in an updated Privacy Policy or Aviso de Privacidad identifying the new responsable).

You may not assign. You may not assign or transfer these Terms or any of your rights or obligations under them, by operation of law or otherwise, without our prior written consent. Any attempted assignment by you in violation of this Section is void.

These Terms bind and benefit the parties and their permitted successors and assigns.

20. Force majeure

We will not be liable for any delay or failure to perform, or for any unavailability or degradation of the Service, that results from causes beyond our reasonable control — including acts of God, natural disasters, epidemics or pandemics, war, terrorism, civil unrest, labor disputes, governmental action, network or power failures, and failures, outages, or discontinuation of the third-party infrastructure and service providers on which the Service depends (including our cloud database, object-storage, content-delivery, media-processing, sign-in, and push providers, such as Apple and Google). During a force-majeure event our obligations are suspended for the duration of the event.

21. Copyright — DMCA notice-and-takedown and repeat-infringer policy

We respect intellectual-property rights and respond to clear notices of alleged copyright infringement.

Submitting a notice. If you believe content on the Service infringes your copyright, send a written notice to our Designated Copyright Agent (below) that includes: (1) your physical or electronic signature; (2) identification of the copyrighted work claimed to be infringed; (3) identification of the allegedly infringing material and information reasonably sufficient to let us locate it; (4) your contact information; (5) a statement that you have a good-faith belief that the use is not authorized by the copyright owner, its agent, or the law; and (6) a statement, under penalty of perjury, that the information in your notice is accurate and that you are the copyright owner or are authorized to act on the owner's behalf.

Counter-notice. If your content was removed and you believe the removal was a mistake or misidentification, you may submit a counter-notice to the Designated Agent containing: (1) your physical or electronic signature; (2) identification of the removed material and its prior location; (3) a statement under penalty of perjury that you have a good-faith belief the material was removed by mistake or misidentification; (4) your contact information; and (5) a statement that you consent to the jurisdiction of the appropriate court and will accept service of process from the complaining party. We may restore the content as permitted by applicable law.

Repeat infringers. We will, in appropriate circumstances and at our discretion, disable or terminate the accounts of users who are repeat infringers.

22. Dispute resolution — binding arbitration and class-action waiver (U.S. users only)

THIS SECTION 22 APPLIES ONLY TO USERS LOCATED IN THE UNITED STATES. IT REQUIRES MOST DISPUTES TO BE RESOLVED BY INDIVIDUAL BINDING ARBITRATION AND WAIVES YOUR RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS ACTION. PLEASE READ IT CAREFULLY. YOU MAY OPT OUT WITHIN 30 DAYS (SEE BELOW).

THIS SECTION 22 DOES NOT APPLY TO CONSUMERS LOCATED IN THE EUROPEAN ECONOMIC AREA, THE UNITED KINGDOM, OR MEXICO, OR ANYWHERE ITS TERMS ARE PROHIBITED BY APPLICABLE LAW. FOR THOSE USERS, SEE SECTION 23 (GOVERNING LAW AND VENUE) AND SECTION 16 (SAVINGS CLAUSE).

(a) Scope and agreement to arbitrate (U.S. users). If you are located in the United States, you and we agree that any dispute, claim, or controversy arising out of or relating to the Service or these Terms (a "Dispute") will be resolved by final and binding individual arbitration, rather than in court, except as provided in subsection (f). This arbitration agreement is governed by the Federal Arbitration Act (9 U.S.C. §§ 1 et seq.).

(b) Informal resolution first. Before starting an arbitration, you agree to first contact us at hello@twenty4.app and give us 30 days to resolve the Dispute informally. Most concerns can be resolved this way.

(c) Arbitration rules and forum. The arbitration will be administered by a recognized arbitration administrator under its then-current consumer arbitration rules, before a single arbitrator. The arbitration may be conducted by submissions, telephone, or video where the rules allow, and, at your election, in your home U.S. county.

(d) Jury-trial waiver. You and we each waive any right to a trial by jury in any Dispute subject to this Section.

(e) Class-action waiver. You and we agree to bring Disputes only in an individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated, or representative proceeding. The arbitrator may not consolidate more than one person's claims and may not preside over any form of class or representative proceeding. If this class-action waiver is found unenforceable as to a particular claim or remedy, that claim or remedy (and only that claim or remedy) will be severed and brought in court, and the rest of this Section will remain in effect.

(f) Exceptions. Either party may bring an individual claim in small-claims court if it qualifies, and either party may seek injunctive or equitable relief in court to protect intellectual-property or confidential information. Nothing here prevents either party from bringing a Dispute to the attention of a relevant government agency.

(g) 30-day opt-out. You may opt out of this arbitration agreement (Section 22) within 30 days of first accepting these Terms by sending written notice to hello@twenty4.app (or to El Pinal 124, Colonia Valle de Chipinque, San Pedro Garza García, Nuevo León, C.P. 66250, México) stating your name, the email associated with your account, and a clear statement that you opt out of arbitration. Opting out of arbitration does not affect any other part of these Terms, and will not affect any prior or later agreement to arbitrate. If you opt out, Disputes will be resolved in the courts identified in Section 23.

23. Governing law and venue

These Terms, and any Dispute not subject to arbitration under Section 22, are governed by the laws of the United Mexican States (Mexico), and specifically the State of Nuevo León, without regard to conflict-of-laws rules. Subject to Section 22 (U.S.-user arbitration) and to any mandatory consumer-forum rights preserved by Section 16, you and we submit to the exclusive jurisdiction of the competent courts seated in Nuevo León, Mexico, for any Dispute.

Consumers' mandatory forums preserved. If you are a consumer, nothing in this Section deprives you of the protection of any mandatory rule, or of your right to bring proceedings in the courts of your country of residence, where the law of your residence so requires — including consumers in the EEA, the United Kingdom, and Mexico (e.g., before PROFECO or the competent local courts).

24. Changes to these Terms; continued use

We may update these Terms from time to time. When changes are material, we will update the version and effective date at the top, and we will notify you in the app and/or by email. For material changes, we may require you to accept the updated Terms before you continue to use the Service. For consumers in the EEA/UK, we will provide at least 30 days' advance notice of material changes before they take effect; if you do not agree, you may stop using the Service and delete your account. For users in Mexico, changes affecting the processing of personal data will also be communicated through an updated Aviso de Privacidad. Continued use of the Service after a change takes effect means you accept the updated Terms, except where applicable law requires your express acceptance.

25. General

Entire agreement; order of precedence. These Terms, together with the Privacy Policy and (for Mexican users) the Aviso de Privacidad, and any subscription terms presented in the app, are the entire agreement between you and us regarding the Service and supersede any prior agreements on the subject. If there is a conflict, the Apple App Store rider (Section 26) controls as to App Store matters; otherwise these Terms control over the Privacy Policy on contractual matters, and the Privacy Policy / Aviso de Privacidad control on matters of personal-data processing.

Severability. If any provision of these Terms is held invalid or unenforceable, that provision will be enforced to the maximum extent permitted and severed to the minimum extent necessary, and the remaining provisions will remain in full force and effect.

No waiver. Our failure to enforce any provision is not a waiver of our right to do so later. A waiver is effective only if in writing and signed by us.

Notices. We may give you notices by email (to the address associated with your account), through the Service, or by posting in the app or on our website. You may send us notices at hello@twenty4.app or at El Pinal 124, Colonia Valle de Chipinque, San Pedro Garza García, Nuevo León, C.P. 66250, México. You consent to receiving electronic communications from us, and you agree that electronic communications satisfy any legal requirement that a communication be in writing, to the extent permitted by law.

Time to bring a claim (limitations period). To the extent permitted by applicable law, any claim arising out of or relating to the Service or these Terms must be brought within one (1) year after the claim arises; otherwise it is permanently barred. This one-year limitation does not apply to consumers in the EEA, the United Kingdom, or Mexico, or anywhere a shorter limitations period is prohibited by law.

Feedback. If you send us suggestions, ideas, or other feedback about the Service, you grant us a perpetual, irrevocable, worldwide, royalty-free, fully sublicensable license to use, modify, and incorporate that feedback for any purpose, without any obligation to compensate you and without confidentiality. You are not required to provide feedback.

Export controls and sanctions (OFAC). You represent and warrant that you are not located in, ordinarily resident in, or a national of any country or territory subject to comprehensive economic sanctions or embargoes, and that you are not on any restricted-party or denied-persons list maintained by the U.S. Government (including the U.S. Office of Foreign Assets Control (OFAC)), the United Nations, the European Union, the United Kingdom, or other applicable authorities. You agree not to use or export the Service in violation of applicable export-control or sanctions laws.

Relationship. Nothing in these Terms creates any partnership, joint venture, agency, or employment relationship between you and us.

26. Apple App Store rider (applies to the iOS app)

This Section applies if you obtained the Twenty4 app from the Apple App Store. In the event of any conflict between this Section and the rest of these Terms, this Section controls with respect to your use of the App Store version of the app.

• These Terms are between you and us, not Apple. These Terms are concluded between you and Pablo Andrés Sheridan Garza (d/b/a Twenty4), and not with Apple Inc. ("Apple"). We, not Apple, are solely responsible for the Twenty4 app and its content.
• Scope of license. The license granted to you for the app is limited to a non-transferable license to use the app on any Apple-branded device that you own or control, as permitted by the Apple Media Services / App Store Terms of Service (Usage Rules).
• No Apple support or warranty obligation. Apple has no obligation to furnish any maintenance or support services for the app. To the maximum extent permitted by law, Apple has no warranty obligation with respect to the app, and any claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to any warranty are our sole responsibility, not Apple's.
• Product claims. We, not Apple, are responsible for addressing any claims relating to the app or your use of it, including product-liability claims, claims that the app fails to conform to legal or regulatory requirements, and claims under consumer-protection or similar laws.
• Intellectual-property claims. We, not Apple, are responsible for the investigation, defense, settlement, and discharge of any third-party claim that the app or your use of it infringes that third party's intellectual-property rights.
• Legal compliance. You represent that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist-supporting" country, and that you are not on any U.S. Government restricted-party list (see Section 25).
• Third-party beneficiary. Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance, Apple will have the right (and is deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
• Apple's terms. You agree to comply with all applicable third-party terms when using the app, including the Apple Media Services / App Store terms.

Service providers referenced in these Terms

The processing of Your Content and personal data relies on a small number of trusted service providers; the Privacy Policy / Aviso de Privacidad is the controlling description of personal-data processing. The categories of providers are:

• Cloud database, authentication & backend — stores your account and content and runs the app's backend, including the magic-link sign-in email.
• Object storage & content delivery — stores your original photos and videos and the thumbnails/previews we generate.
• Media processing — generates video thumbnails and short preview clips.
• Subscription & app-store billing — manages plans and in-app purchases. We never receive or store your card details.
• Sign-in & push notifications — Sign in with Apple, Google sign-in, and Apple's push service. Push delivery exposes only the short notification text (for example, "{name} invited you"), never your journal content. We do not use Firebase/FCM.
• Product analytics — privacy-respecting usage data tied only to an opaque identifier, never your email or your content. You can opt out.
• Error diagnostics — crash and error reports, scrubbed of your content.
• AI (future, not yet active) — would process only the text you choose to submit to an AI feature, and only with your explicit consent. No data flows to any AI provider today.

Several of these providers are based in the United States. A list of the specific companies we use is available on request: email privacy@twenty4.app.

Note on data, privacy, and security disclosures

For cross-reference only; the Privacy Policy / Aviso de Privacidad controls. These Terms incorporate by reference the Privacy Policy and, for Mexican users, the Aviso de Privacidad, which describe how we handle personal data, including:

• Categories of data we process: account information (an opaque identifier and the email from your Apple/Google/email sign-in), Your Content (events, notes, photos, videos, comments), usage analytics (opaque identifier and non-identifying buckets), diagnostics (crash and error reports), and device push tokens.
• EXIF/GPS metadata. Original photos and videos you upload may contain embedded location data (EXIF GPS). We retain your originals with that metadata so that you can access your own files; when media is served to other members of a shared event, location metadata is stripped from the served copy.
• CDN-served derivatives. Thumbnails and preview clips are served from behind unguessable random URLs for performance. If such a URL is shared or leaked, the derivative could be fetched without re-authentication; your original files remain protected behind access-controlled, time-limited links. We disclose this tradeoff.
• Collaboration exposure. When you join a shared event, your display name (or the local part of your email) and the media you add are visible to the other members.
• Encryption posture. Your data is encrypted in transit (TLS) and at rest (provider defaults), and is protected by per-user, server-side access controls (row-level security). This is not end-to-end encryption — see Section 17. We do not claim we are unable to read Your Content.
• Retention. Account deletion is immediate and permanent (Section 10), subject to short, standard backup-rotation windows and to legally required records (including Mexican fiscal/billing retention). We may in the future apply an inactivity auto-deletion (~2 years) (Section 9) and a free-tier over-limit grace-then-removal process (Section 8); those future enforcement behaviors are authorized by these Terms.

This policy is provided for transparency and is a draft pending final review by counsel.
