All messages in our Signal groups are end-to-end encrypted using the Signal protocol. Neither Signal itself nor any third parties can read them. Even metadata, such as group memberships, is not stored on the servers.
Signal is operated by a nonprofit foundation and is funded exclusively by donations. It has no advertising-based business model, does not engage in profiling, and does not sell user data to third parties.
Signal’s entire source code is publicly available and is regularly reviewed by independent security researchers. This allows anyone to see how your data is processed. No black box—just full transparency.
Signal is recommended as a secure alternative by nearly all German data protection authorities. Unlike other messaging apps, Signal stores almost no personal data on its servers—only your registration date and the time of your last connection.
