FAQ · A few good questions

Questions, answered.

One app for the everyday work of a small company: chat, mail on your own address, calendar, contacts, files, and voice and video calls. Every company gets its own private space.

Request a pilot space with the form below. We set up your space at yourcompany.desyr.chat with a first admin account; your admin then adds the team, and everyone gets a link by mail to choose a password.

Nothing. desyr is free for pilot companies for the whole pilot, with no credit card and no automatic upgrade.

We’ll tell you the price before the pilot ends. If you’d rather not continue, we’ll help you take your data with you.

On desyr’s servers in Switzerland, with encrypted backups. Each company has its own separate space, and no other company can see into it.

Not your direct chats or encrypted channels: they are end-to-end encrypted, and only their members hold the keys. Mail, calendars and files are stored on our servers in Switzerland, and we never use them for ads or analysis.

No. desyr runs in the browser, and installs like an app on iPhone, Android, Mac and Windows, with notifications. No app store needed.
