Privacy Policy

Rethink DNS + Firewall are anti-surveillance tools first and foremost: It is absolutely against our ethos, then, to track users of our apps and services, or sell any information whatsoever to any third-party in any form, pseudo-anonymized, de-anonymized, anonymized, aggregated, or otherwise.

App Privacy Policy

We do not collect, sell, license, share any data (personally identifiable or otherwise) from the Rethink DNS + Firewall Android app.

  • The app is free of any trackers, spyware, ads, or loggers whatsoever. This can be, to an extent, ascertained from our code which is open-source on GitHub.
  • The app does not use or depend on or embed any third-party services in its default setting. The only exception is Google PlayStore (see their privacy policy) which is used as an app distribution channel.
  • The app does not collect any debug or diagnostic data unless you explicitly choose to share it with us, for example, over email.
