End-to-end encrypted
Messages, files, pictures, calls and calendar events are encrypted on your device with post-quantum hybrid cryptography (ML-KEM-1024 with P-384). The server stores and forwards only ciphertext.
Our apps
Snack — private messaging for teams.
Snack is an end-to-end encrypted messenger for conversations, files, calls and calendars, developed and published by Blyg AB. Only the people in a conversation can read it: not the server, and not us.
Features
Everything a team talks about, encrypted.
Sign in with a YubiKey
Your key can live on a YubiKey, so it never leaves the card. Single sign-on and passphrase-protected keys are supported too.
Rooms and direct messages
Group rooms with roles and moderation, direct messages, replies, reactions, pinned messages, formatted text and file sharing.
Calls and meetings
Encrypted voice and video calls, screen sharing, and meetings that guests without an account can join with a link and a password.
Calendar
Invitations, answers and reminders, end-to-end encrypted like everything else, with optional free/busy sharing between colleagues.
Your own server, if you want
Use Snack on the servers Blyg AB runs, or host it for your organisation. Servers connect to each other, so people on different servers can talk.
Platforms
On every device you use.
One account works on all of them, and your conversations follow you.
- Android phones and tablets
- iPhone
- Web browsers, with the Snack YubiKey extension for Chrome and Firefox
- Windows and Linux desktop app
- A terminal client and a command-line tool for Linux
Privacy and safety
Snack contains no advertising, analytics or tracking. What a Snack server can and cannot see, and how long it is kept, is described in the Privacy Policy. Using Snack is subject to our Terms of Use, which do not allow objectionable content or abusive behaviour.
You can leave any conversation, room moderators can remove and ban people, and you can block people from contacting you. To report abuse, a user or a message, or to close your account, e-mail dev@blyg.se; we act on reports within 24 hours.
