faast: speed meets privacy

About this app

faast is a messenger built around your privacy. Messages, photos, voice notes, files and calls are end-to-end encrypted: only you and the people you talk to can read them, not even we can.

CHATS THAT STAY YOURS
• Private and group chats, channels, voice messages, photos, videos and files
• Audio and video calls, and a walkie talkie for quick voice messages
• Polls and events with the place on the map: one tap opens the navigator
• Share your position, once or live for a while
• Timed messages that delete themselves
• Locked chats: hidden behind a secret code, on all your devices
• Block or report anyone, the assistant included

DANA, YOUR ASSISTANT
Dana lives in a chat like a friend. Ask her to remind you of something, to add an event to your calendar, to summarise a long chat or to find information. She answers in your language. What you write to Dana is processed by our servers so that she can answer.

ONE ACCOUNT, EVERY DEVICE
Use faast on your phone, on your computer (Windows, macOS, Linux) and in the browser. Your history can be backed up, protected by a password only you know.

PRIVACY BY DESIGN
• Post-quantum protection: chats and groups use hybrid ML-KEM encryption, built to resist future quantum computers
• Standard, open cryptography (MLS, the IETF messaging standard)
• No ads and no tracking
• Optional connection through Tor
• Delete your account at any time, from the app or from faast.chat

What’s new

A new phone joins all chats right away. The phone number starts with your country code. Archived chats stay archived. Dates and distances follow the app language. The version is shown in Settings.
