Encryption

Isshio encrypts every group end to end. You need no account, no email address and no phone number.

How it works

1. Every group has a twelve-character code, for example ABCD-EFGH-JKLM. It is both the way in and the key.

2. Before your device stores the group online, it encrypts it with this code. The code itself never goes to the server, not even in the invitation link.

3. The server only sees unreadable data. Without the code nobody can read the group, not even the operator.

4. Anyone who has the code can read and change the group. Only share it with people who take part.
