ClearKeep Android

Clearkeep is a free and open source software application for Android, iOS, that employs end-to-end encryption (E2EE) to keep communications safe.

Communications can be made between either individuals or a group, allowing users to send end-to-end encrypted text, picture, as well as engage in live video and audio calls.

Default end-to-end encryption scaling to thousands of users per room. We protects against accidental leaks, eavesdroppers and third party interference by ensuring that by default the server cannot see your conversations.
