Terms of Use

Last updated: 5 August 2026

These Terms of Use ("Terms") govern your use of the Retainory app for iOS ("Retainory", "the app"). By downloading or using the app, you agree to them. If you don't agree, please don't use the app.

1. The service

Retainory helps you study by generating flashcards from material you provide and scheduling reviews of those cards over time. Retainory is currently offered free of charge. We may introduce paid features in the future; if we do, we'll make the terms of any purchase clear before you buy.

2. No account

Retainory does not require an account. Your study data is stored on your device. You are responsible for your device and for retaining your own copies of anything you care about — deleting the app deletes your data permanently, and we cannot recover it.

3. Your content

You keep all rights to the notes, documents, and text you provide ("Your Content"). You grant us only the limited permission needed to process Your Content in order to generate flashcards for you — that is, to transmit it to our service providers and return the results. We do not use Your Content to train models.

You agree that you will not submit content that:

• you don't own or otherwise have the right to use;
• infringes anyone's copyright, trademark, or other rights;
• is unlawful, or contains someone else's personal or confidential information without their permission.

4. Generated flashcards are not guaranteed to be correct

5. Acceptable use

You agree not to:

• access the service by any means other than the Retainory app, or attempt to bypass its rate limits, device attestation, or other protections;
• reverse engineer, decompile, or attempt to extract credentials from the app, except where that right cannot be restricted by law;
• use the service to generate unlawful, harassing, or abusive content;
• interfere with the service, or place an unreasonable load on it through automated or bulk use.

We may limit or suspend access to the generation service if it's being abused, or to protect the service's availability for everyone else.

6. Availability

Flashcard generation depends on our servers and on third-party providers, and is offered on an "as available" basis. There may be downtime, capacity limits, or changes to how generation works. The scheduling and review parts of the app run on your device and continue to work offline.

7. Our intellectual property

The app itself — its software, design, and the Retainory name and logo — belongs to us. These Terms grant you a personal, non-exclusive, non-transferable, revocable licence to use the app on Apple devices you own or control, in accordance with the App Store Terms of Service.

8. Disclaimers

To the fullest extent permitted by law, Retainory is provided "as is" and "as available", without warranties of any kind, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement.

9. Limitation of liability

To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, study progress, academic outcomes, or profits, arising out of or relating to your use of the app. Where liability cannot be excluded, our total liability is limited to the greater of the amount you paid us for the app in the twelve months before the claim, or USD 25.

Nothing in these Terms limits liability that cannot be limited under applicable law, including your statutory consumer rights.

10. Apple

These Terms are between you and us, not with Apple, and Apple is not responsible for Retainory or its content. Apple has no obligation to provide support for the app. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. If the app fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any); to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app.

11. Changes to these Terms

We may update these Terms. If we make material changes, we'll update the date at the top of this page and surface the change in the app. Continuing to use Retainory after a change means you accept the updated Terms.

12. Termination

You may stop using Retainory at any time by deleting the app. We may suspend or terminate access if you breach these Terms.

13. Governing law

These Terms are governed by the laws of the State of California, excluding its conflict-of-law rules, without limiting any mandatory consumer protections available to you where you live.
