Proton OS Privacy Policy

At Proton OS, we believe privacy is a fundamental human right, not an adjustable setting or a premium feature. Operating systems should serve their users—not collect background telemetry, build advertising profiles, or monitor how hardware is used.

​

This Privacy Policy outlines our strict commitment to your privacy regarding both the Proton OS Operating System and the Proton OS Website and Services.

1. The Proton OS Operating System

Zero Telemetry & Zero Tracking

​

  • No Background Telemetry: Proton OS contains zero telemetry, spy software, or user-behavior tracking mechanisms. We do not collect metrics on what applications you run, how long you use your system, or your hardware configuration.

​

  • No Cloud Account Required: You do not need to create an online account, register an email address, or log into a network to install or use Proton OS. Your local administrator account and data reside strictly on your device.

​

  • Local Data Stays Local: Files, documents, browsing history, and system settings are never transmitted to Proton OS or any third-party servers.​

​

System Updates & Software Repositories

​

  • When your system checks for or downloads updates, it connects directly to official upstream Debian software repositories.

​

  • These connections function as standard HTTPS requests. The package manager transmits only the minimum information necessary to fetch updates (such as package names and system architecture). No unique hardware IDs, personal identifiers, or serial numbers are ever attached to update requests.

​

​

2. Proton OS Website & Infrastructure

Web Server Logs

​

When you visit our website, download the Proton OS ISO, or access documentation, our web servers automatically record standard, temporary HTTP connection logs. These logs typically include:

​

  • Your IP address

  • Date and timestamp of the request

  • Web browser type (User-Agent string)

  • Requested page or file (e.g., ISO download link)

​

Why we log this: These logs are strictly used for network security, preventing Denial of Service (DoS) attacks, monitoring server bandwidth, and ensuring reliable ISO mirror performance. Server logs are automatically overwritten and purged on a regular schedule and are never linked to personal identities.

​

Cookies

  • The Proton OS website is designed to be as lightweight and privacy-respecting as possible.

  • We do not use third-party tracking cookies, behavioral advertising cookies, or cross-site tracking scripts.

  • If cookies are used, they are strictly necessary for core website functionality (such as remembering display preferences).

​​

​

3. Third-Party Services & Financial Contributions

​

If you choose to support Proton OS financially through external donation platforms (such as GitHub Sponsors, Open Collective, or PayPal):

​

  • Financial transactions are processed entirely by those respective payment providers.

  • Proton OS does not collect, process, or store your credit card numbers or banking information on our servers.

  • Please review the privacy policies of those specific payment platforms when making a contribution.

​

​

4. Links to External Websites

​

Our website or documentation may contain links to third-party sites (such as external software documentation, ISO Repository, Debian upstream resources, or community forums). Proton OS is not responsible for the privacy practices or content of external third-party websites.

​​

​

5. Changes to This Policy

​

We may update this Privacy Policy periodically to reflect changes in our infrastructure or legal requirements. Any modifications will be posted directly to this page with an updated "Last Updated" date. Because we do not collect user emails, we encourage users to check this page periodically for updates.
