Sleutl provides end-to-end encrypted communication. Your messages, photos, and videos are only readable by you and the recipient.
Built with privacy as the foundation
Messages are encrypted on your device and only decrypted on the recipient's device. We cannot read your messages.
We use the proven Signal Protocol - the same encryption trusted by security experts worldwide.
