About CalyxOS

Everyone needs a phone. Not everyone wants governments and corporations tracking their every move and spying on their communications. CalyxOS lets you have your cake and eat it too, with “Privacy by Design”

In social science, agency is defined as: the capacity of individuals to act independently and to make their own free choices. There is a whole community of free software developers working to build tools that enable us to take back our privacy, and we have curated a collection of the “best of the best” in order to give you back your agency.

When you use a phone with CalyxOS:

  • you are empowered by the combined expertise of the Internet privacy community
  • ‘de-googled’ Android - does not put your data in google’s cloud or constantly report your location to google
  • you can make encrypted phone calls directly, using the built-in integration for Signal and WhatsApp calls
  • you are warned when you make or receive an unencrypted phone call
  • text messages are encrypted and a timer can be set so they disappear
  • advertising and trackers blocked via DuckDuckGo Browser and DuckDuckGo as default search provider
  • web browsing is anonymized via Tor Browser
  • built-in free “Virtual Private Network” services from trusted organizations protect you from being spied on
