Terms of Use for D-Schutz

Last updated: 2026-09-03

These terms govern your use of D-Schutz ("the app"), a local, offline PDF reader with an on-device AI assistant, developed and operated by Medina Labs (Max Francisco Medina Estrella), reachable at max@medina-labs.com. By downloading, installing, or using the app, you agree to these terms. If you do not agree, do not use the app.

License

Medina Labs grants you a personal, non-exclusive, non-transferable, revocable license to install and use D-Schutz on devices you own or control, for your own personal or internal purposes. You may not copy, modify, reverse-engineer, redistribute, or sell the app, except to the extent applicable law gives you the right to do so despite this restriction.

Your responsibilities

You are responsible for the PDF documents you import into the app, for having the right to use and store them, and for keeping your device secure. D-Schutz processes documents on-device; see the Privacy Policy for details on how imported and password-protected documents are handled, including the fact that a decrypted copy of a password-protected PDF is stored in the app's private storage without its own password protection.

Third-party services

D-Schutz downloads AI model files from Hugging Face and may use Google ML Kit and Google Play services (for the optional document scanner), each governed by its own terms and privacy policy, outside Medina Labs' control. See the Privacy Policy for details on what is transmitted to these services.

No warranty

D-Schutz is provided "as is" and "as available," without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. The on-device AI assistant's answers and summaries may be inaccurate or incomplete — do not rely on them for decisions where accuracy is critical without independently verifying the source document.

Limitation of liability

To the maximum extent permitted by applicable law, Medina Labs and Max Francisco Medina Estrella shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, arising from or related to your use of the app — including, without limitation, any exposure of a decrypted PDF copy resulting from loss, theft, or compromise of your device, as described in the Privacy Policy. For ordinary negligence, liability is limited to breaches of essential contractual obligations (Kardinalpflichten) whose fulfillment makes proper use of the app possible in the first place, and even then only to foreseeable, typical damages. Nothing in these terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for intent or gross negligence, for injury to life, body, or health, or under the German Product Liability Act (Produkthaftungsgesetz).

Termination

You may stop using the app and uninstall it at any time. Medina Labs may discontinue or modify the app at any time. Sections that by their nature should survive termination (including "No warranty" and "Limitation of liability") will survive.

Changes to these terms

If these terms change, the "Last updated" date above will be revised. Continued use of the app after changes are published constitutes acceptance of the revised terms.

Governing law

These terms are governed by the laws of the Federal Republic of Germany, excluding its conflict-of-law rules, without prejudice to any mandatory consumer-protection provisions of the country in which you reside.
