incredibly secure messaging that feature a self-destruct option for text, images and videos.
All the messages use multi-layer encryption with AES256 and ECDH521 and are never stored on any servers.
The desktop app also removes all metadata and is completely anonymous, with only your devices having the key that can reveal messages directed at you.
In addition to being able to set a time limit for all individual messages (with a maximum of six days), you can “forensically” wipe the deleted messages from your computer.
In other words, once it’s gone, it’s really gone.
