Terms

What we promise

To carry envelopes and not look inside them. Not to sell or hand over what we know to anyone - except where the law demands it; and then we can only hand over what we have, and we have very little (see Privacy).

What we do not promise

That the server will run without interruption. That your conversations will survive the loss of your phone. That encryption will protect you from a person you showed your screen to yourself.

What is not allowed

Using Tysha for threats, stalking, distributing child sexual abuse material, or anything else that lands people in prison in any country. We cannot see the content of conversations - so the only thing we can do is accept a report from the recipient and cut off access to the server.

Price

The app is free. If a paid part ever appears, it will not be payment for privacy: privacy is not a feature, it is a condition.

Age

Tysha is not intended for children under 13.
