Terms of Service

Effective date: July 16, 2026 · Last updated: July 16, 2026

LearnLocker requires a subscription via the App Store (monthly or yearly; yearly may include a free trial). App shielding is a self-management tool on your device, not a parental control for someone else's phone. AI-generated questions can be wrong; check your notes.

These Terms of Service ("Terms") govern your access to and use of the LearnLocker iOS application and related services ("LearnLocker", the "Service"). The Service is provided by the publisher of the LearnLocker app on the Apple App Store ("we", "us", or "our"), reachable at support@learnlocker.app. By downloading or using LearnLocker you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

1. What LearnLocker does

LearnLocker helps you build a study habit by shielding apps you select until you complete a daily study goal: clearing a flashcard review queue, or passing a quiz generated from notes you upload. You choose a single unlock gate in Settings. App shielding uses Apple's Screen Time and Family Controls frameworks and runs on your device.

2. Eligibility

You must be at least 13 years old (or the minimum age of digital consent in your country, if higher) to use LearnLocker. If you are under 18, you may use the Service only with a parent or guardian's permission. You represent that you have the legal capacity to agree to these Terms.

3. Accounts and identity

LearnLocker does not offer traditional accounts. The app creates an anonymous device identifier used to associate Quiz Mode data, progress sync, and subscription status on our servers. You are responsible for activity associated with that identifier on devices you control. Keep a copy of your Device ID (Settings → About) if you may need support or deletion.

4. Subscriptions and billing

• LearnLocker requires a subscription to use the app (flashcards, AI quizzes, locking, and progress). Plans are auto-renewable monthly or yearly through Apple. The yearly plan may include a free trial (for example a 3-day trial) for eligible new subscribers, as shown in the App Store and in-app purchase sheet at the time of purchase. There is no free tier beyond that trial.
• Payment is charged to your Apple ID through the App Store. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. A free trial converts to a paid subscription unless cancelled before the trial ends.
• Manage or cancel anytime in your device Settings under Apple ID → Subscriptions (or the equivalent App Store subscription management screen). Deleting the app does not cancel a subscription.
• Prices are displayed before purchase and may change for future periods; Apple will notify you as required by its policies and applicable law. Refunds are handled by Apple under App Store refund rules; contact Apple for refund requests.

5. Fair use limits

To keep the Service reliable and affordable, Quiz Mode uploads and quiz generation are subject to per-day limits (currently 20 uploads and 15 generations per user per UTC day by default). If you reach a limit, the app will show an error and you can try again the next day. We may adjust limits to protect the Service, prevent abuse, or manage costs. Circumventing limits is a violation of these Terms.

6. Your content

• You retain all rights to study materials you upload. You grant us a worldwide, non-exclusive, royalty-free license to host, store, process, transmit, and display that content (including to our AI and storage providers) solely as needed to operate and improve the Service for you, for example extracting text and generating quiz questions.
• You are responsible for what you upload. Upload only materials you have the right to use. Do not upload content that is unlawful, infringing, harmful, or that contains other people's personal information without authorization. Do not upload sensitive documents the Service is not designed for (see the Privacy Policy).
• We may remove or disable access to content that violates these Terms or that we reasonably believe creates legal or security risk.

7. Acceptable use

You agree not to:

• Misuse, overload, disrupt, or attempt to gain unauthorized access to the Service or related systems;
• Circumvent usage limits, entitlement checks, Screen Time controls, or security measures;
• Use automated scripts, scrapers, or bots against our API except as we expressly allow;
• Reverse engineer the app except to the extent such restriction is prohibited by applicable law;
• Resell, sublicense, or provide the Service to third parties as a commercial service of your own;
• Use the Service for any unlawful purpose.

8. AI-generated content

Quiz questions are generated automatically by artificial intelligence from your materials. They may be inaccurate, incomplete, biased, or misleading. Always verify important information against your source material. LearnLocker is a study aid. It does not provide professional, medical, legal, financial, or academic advice, and it is not a substitute for your own judgment or official course materials.

9. App shielding

App shielding is a self-management tool built on Apple's frameworks. You control it: you choose the apps, you grant (and can revoke) Screen Time / Family Controls permission, and you can remove the app at any time. We do not guarantee that shielding will function in every circumstance (including after iOS changes, permission revocation, Focus modes, device management profiles, or hardware limits). You should not rely on LearnLocker as a parental control, workplace monitoring tool, or security mechanism for another person's device.

10. Intellectual property

The LearnLocker app, name, logos, and related software and content (excluding your uploads) are owned by us or our licensors and are protected by intellectual property laws. These Terms grant you only a personal, non-exclusive, non-transferable, revocable license to use the app on Apple-branded devices you own or control, as permitted by the App Store Terms of Service / Licensed Application End User License Agreement.

11. Third-party services

The Service depends on third parties (including Apple, Cloudflare, OpenAI, and our database host). Their availability and terms can affect the Service. We are not responsible for third-party outages or changes outside our reasonable control, except to the extent required by law.

12. Termination

You may stop using LearnLocker at any time. We may suspend or terminate access to server-side features if you materially violate these Terms (for example API abuse or unlawful uploads), or if we discontinue the Service. We will try to provide reasonable notice when practicable. Sections that by their nature should survive (including your content license for copies already processed, disclaimers, liability limits, Apple-related terms, and governing law) survive termination.

13. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, OR THAT ANY CONTENT (INCLUDING AI-GENERATED QUESTIONS) WILL BE ACCURATE OR COMPLETE. SOME JURISDICTIONS DO NOT ALLOW CERTAIN DISCLAIMERS; IN THOSE CASES, THE DISCLAIMER APPLIES TO THE MAXIMUM EXTENT PERMITTED.

14. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE AND OUR SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, PROFITS, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING FROM OR RELATED TO YOUR USE OF (OR INABILITY TO USE) THE SERVICE. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU PAID US THROUGH THE APP STORE FOR LEARNLOCKER IN THE 12 MONTHS BEFORE THE CLAIM AROSE, OR (B) USD $50. THESE LIMITS APPLY EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS; IN THOSE CASES, OUR LIABILITY IS LIMITED TO THE MAXIMUM EXTENT PERMITTED BY LAW.

15. Indemnity

You agree to defend and indemnify us from and against claims, damages, losses, and expenses (including reasonable attorneys' fees) arising from your uploaded content, your misuse of the Service, or your violation of these Terms or applicable law, except to the extent caused by our willful misconduct.

16. Apple App Store terms

These Terms are between you and us, not Apple Inc. ("Apple"). Apple has no obligation to provide maintenance or support for the app. To the maximum extent permitted by law, Apple is not responsible for addressing any claims by you or any third party relating to the app or your possession and use of it, including product liability claims, claims that the app fails to conform to legal or regulatory requirements, and claims arising under consumer protection or similar legislation. In the event of any failure of the app to conform to an applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any) for the app; to the maximum extent permitted by law, Apple has no other warranty obligation. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. Your use of the app must also comply with the App Store Terms of Service and any applicable usage rules.

17. Governing law and disputes

These Terms are governed by the laws of the State of California, United States, without regard to conflict-of-law rules, except where the mandatory laws of your country of residence provide otherwise. Subject to those mandatory protections, exclusive jurisdiction and venue for disputes will lie in the state or federal courts located in California, and you consent to personal jurisdiction there. Nothing in these Terms limits any non-waivable consumer rights you may have under the laws of your place of residence.

18. Export and sanctions

You may not use or export the app except as authorized by United States law and the laws of the jurisdiction in which the app was obtained. You represent that you are not located in a country subject to a U.S. government embargo and are not on any U.S. government list of prohibited or restricted parties.

19. Changes to these Terms

We may update these Terms from time to time. If changes are material, we will update the "Last updated" date above and, where appropriate, notify you in the app. Continued use of the Service after changes take effect means you accept the updated Terms, except where applicable law requires a different process.

20. Miscellaneous

These Terms, together with the Privacy Policy, are the entire agreement between you and us regarding the Service. If any provision is held unenforceable, the remaining provisions remain in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets. Headings are for convenience only.
