Terms of Service

Last updated: 17 September 2026 Version 1.0 Xilistudios

1. Acceptance of these terms

By installing, running or otherwise using Monark Password Manager, you agree to these Terms of Service. If you do not accept them, do not use the application.

2. Nature of the software and licence

Monark is a local-first, open-source credential and password management application.

The source code is distributed under the terms of the GNU Affero General Public License version 3.0 (AGPL-3.0). You are free to inspect, audit, modify and redistribute the code under the terms of that licence. The full licence text is available in the project's official GitHub repository.

3. User responsibility and the zero-knowledge model

Critical notice about your master password

Monark operates under a zero-knowledge cryptographic model. Your data is encrypted on your own device using your master password and derived keys (Argon2id and XChaCha20-Poly1305).

Xilistudios does not store, does not know and cannot reset your master password under any circumstance. If you forget your master password and hold no recovery key or backup, your data cannot be recovered.

You alone are responsible for:

  • Choosing a strong master password and keeping it safe.
  • Generating and retaining backups of your data and recovery keys.
  • Maintaining the physical and logical security of the devices on which Monark is installed.

4. Integration with third-party services (Google Drive)

Monark supports optional synchronisation with cloud storage provided by third parties, in particular Google Drive through OAuth authentication.

  • Use of Google Drive is subject to Google's Terms of Service.
  • Monark requests access only to manage backup files generated by the application itself (the drive.file scope), which are encrypted end to end before being sent.
  • Xilistudios is not responsible for connectivity failures, service interruptions or storage limits imposed by third-party cloud providers.

5. Acceptable use

You agree to use Monark only for lawful purposes. It is strictly prohibited to use the software to:

  • Store, manage or distribute credentials obtained unlawfully or without authorisation.
  • Attempt to breach, disable or circumvent the security measures of third-party services or systems you do not own.

6. Exclusion of warranties

To the maximum extent permitted by applicable law, the software is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, express or implied, including but not limited to the implied warranties of merchantability, fitness for a particular purpose or non-infringement.

Although we work to maintain high standards of quality, security and testing, Xilistudios does not warrant that the application will operate uninterrupted, be entirely free of errors, or be compatible with every hardware or software configuration.

7. Limitation of liability

Under no circumstances shall Xilistudios, its developers or contributors be liable for direct, indirect, incidental, special, consequential or punitive damages, including lost profits, data loss, business interruption or computer failure arising from the use of, or inability to use, the application.

8. Modifications to these terms

Xilistudios reserves the right to modify or update these Terms of Service at any time. The last-revision date will be updated at the top of this page. Continued use of the application after any change is published constitutes acceptance of the new terms.
