Rasum Help

Rasum is a messenger for iPhone and Android. You can use it to write messages, send photos, files and voice messages, and make voice or video calls – with single people and in groups.

What is Rasum?

Rasum is a messenger app for the iPhone and for Android phones. New chats are end-to-end encrypted: only you and the people in the chat can read the messages. A chat without encryption is marked as “Not encrypted” in the chat info. Your account is always on the Rasum server rasum.chat. You cannot choose a different server in the app.

Your username has the form @name:rasum.chat. Other people find you by this name.

The app always uses the dark design. It shows its texts in the language of your phone, for example English, German or Russian.

How do I get started?

Download the app, create an account and sign in. You can find step-by-step instructions under Getting started.

Getting started – install the app, create an account, sign in
Write a message – send, reply, mention
Start a new chat – with one person or as a group
