Terms of Use

1. Acceptance

By using Margent, you accept these terms and the Privacy Policy. If you do not agree, do not use Margent and delete the app.

2. What Margent is

Margent helps you save thoughts, quotes, and notes, organize a private library, and return to saved material. Core features work locally. An account is required for synchronization, server-side export, account deletion, and profile-related features.

The private Reading Circle is invitation-only and may be available in a public or test build. Its membership and capabilities may evolve, but your private library is not published automatically.

3. Account

Sign-in uses a one-time email code or Sign in with Apple when that method is available. You are responsible for access to your device, email, and Apple ID. Margent does not ask for your Apple ID password.

Do not share sign-in codes. If you suspect unauthorized access, sign out through the profile and contact support.

4. Optional email

You may separately consent to receive Margent news and materials by email. This consent is not required to sign in or use the app, is never enabled automatically, and can be withdrawn in settings or through an unsubscribe link. Messages containing sign-in codes you request are service emails and do not depend on marketing preferences.

5. User content and copyright

Your material

You retain rights in notes, comments, and other original material you create. Margent does not acquire ownership or exclusive rights in that content.

Quotes and excerpts from third-party works

Rights in excerpts from books, articles, and other works remain with their authors and other rights holders. Saving text in Margent does not transfer those rights to you, and labeling something a quote does not by itself make every use lawful.

By adding or sharing material, you confirm that you have the right to do so: you created it, obtained permission, or the use is allowed by law. Subject to its requirements, Russian law permits, among other things, reproduction of a lawfully published work for personal purposes under Article 1273 of the Civil Code of the Russian Federation and quotation from lawfully published works to the extent justified by the purpose, naming the author and source where they appear in the source, under Article 1274.

Technical permission for Margent

To operate features you choose, you grant Margent a limited, non-exclusive, royalty-free permission to store, process, create necessary technical copies of, synchronize, and display content only to you and recipients you select. This permission lasts while the content remains in the service and does not allow Margent to use it for advertising, sale, or independent publication. Your private library is not published automatically.

6. Rights-holder notices

A rights holder or authorized representative may report suspected infringement to hello@tuaev-dev.ru. The notice should include:

• the claimant’s name or entity and a contact for response;
• the work or other protected subject matter and the basis of the claimant’s authority;
• information sufficient to locate the disputed material in Margent;
• a description of the infringement and requested action;
• confirmation that the notice is submitted in good faith and that its information is accurate.

Margent may request reasonable evidence of rights and authority. After receiving a sufficiently substantiated notice, we review it and promptly take necessary and proportionate action, including restricting access to or deleting disputed material, notifying the user, and complying with mandatory law. The user may provide explanations and evidence of a lawful basis for use. This procedure takes into account Article 1253.1 of the Civil Code of the Russian Federation concerning persons that provide the technical ability to place or access material.

7. Prohibited use

You may not use Margent for:

• unlawful activity, threats, harassment, stalking, or spam;
• infringement of copyright, privacy, or other rights;
• sharing complete works or substantial excerpts without a lawful basis;
• distributing defamation, unlawfully obtained personal data, or prohibited information;
• accessing another person’s account, data, or infrastructure;
• bypassing restrictions, large-scale automation, or attacks on the app or API;
• transmitting malicious material or abusing reporting mechanisms.

8. Service availability

We work to keep Margent available, but do not guarantee uninterrupted access, error-free operation, or compatibility with every device. TestFlight and other test builds may be unstable and may use a testing environment.

9. Margent does not replace professional advice

Margent is not a medical, psychological, legal, financial, or crisis service. Saved and returned material does not replace help from a qualified professional.

10. Access restrictions

Access to content, an account, or a feature may be restricted when these terms are violated, a sufficiently substantiated rights complaint is received, there is a security threat or abuse, the law requires it, or the service is discontinued. A restriction is limited in scope and duration to what is reasonably necessary to address the cause. Where possible and lawful, we explain the reason and allow the user to respond. You may stop using the service and delete your account at any time.

11. Export and deletion

You can download a copy of server-side data in settings. You can also delete the account there after two confirmations. See the separate instructions.

12. Rights in Margent

Rights in the Margent app, brand, design, code, documentation, and service elements belong to Oleg Aleksandrovich Tuaev unless stated otherwise. These terms do not transfer rights in the brand or software code to you.

13. Liability

Margent is provided “as is” to the extent permitted by applicable law. We do not exclude consumer rights or liability that cannot be limited by agreement. You are responsible for backing up important local material and for decisions made on the basis of saved content.

You decide what content to save and whom to share it with, and you are responsible to third parties for your actions and material, including having rights or another lawful basis, correctly naming the author and source, respecting privacy, and avoiding defamation and prohibited information.

Margent provides technical tools for storage, synchronization, and sharing; it is not the author of user content, does not endorse it, and ordinarily does not review a private library before material is added. To the extent permitted by law, Margent is not liable for an infringement caused solely by user content or actions where we did not know and should not have known of the unlawfulness and, after receiving a sufficiently substantiated notice, promptly took necessary and proportionate action.

These provisions do not release Margent from liability for its own acts or omissions and do not limit mandatory user rights, including consumer rights. Deleting material from Margent cannot remove screenshots or copies recipients made outside the service, so share material with care.

14. Governing law

These terms are governed by the law of the Russian Federation unless mandatory rules in your country require otherwise. Mandatory consumer rights remain in force. Before going to court, the parties will try to resolve the issue through support.

15. Changes and contact

If these terms change materially, the version date will be updated. For questions about using Margent, email hello@tuaev-dev.ru.
