What to include

The build number - it is in Settings under «Version», and tapping it copies the number together with the commit and build time. If it is about a call, add the call trace from Diagnostics: there is a «copy» button there. None of this contains message text or keys - only states and numbers.

Common questions

How do I add someone?

Show them the QR code from «My profile» or send them the link. The code is single-use and lives fifteen minutes. Whoever used it appears on your side with a question: accept or decline.

Why can't anyone find me by search?

There is no people search here, deliberately. Every connection starts with a code you handed over yourself.

A call has no sound

Open Diagnostics → Last call trace. «Path found» means the connection was built; «audio: sent / received» tells you whether bytes are actually flowing. If bytes flow only one way, send us both traces - yours and the other side's.

I lost my phone

If you wrote down your twelve words, set the app up on a new phone and type them in: the account comes back - contacts, groups and settings. The conversations do not: they were only on that phone, and the encrypted backup on our server deliberately does not contain them. Without the words nobody can help, us included: the key to the backup is derived from them.

How do I delete my account?

Settings → Data → Delete account, or see Delete your account.

For companies

Can the whole team start now?

Yes, in the Tysha cloud: everyone installs the app, and colleagues connect with one-time codes - no phone numbers, no passwords. A console where a company issues seats and manages access is in development; what it will hold is on the For companies page.

Where is the data kept?

The server and the call relay are in the EU. Conversations live only on the participants' phones; the server holds only encrypted envelopes until delivery, for no more than 30 days, and files for up to 14 days.

Will the company admin see our messages?

No. The company console will manage seats, rules and devices, but it will not see content, contacts or who writes to whom. Neither the company nor we hold the encryption keys.

Can we run the server ourselves?

A dedicated server for your organisation in our infrastructure and deployment in your data centre or cloud are in development and done for a specific order. Write to us with the number of people and your requirements - we will tell you the stage and the timeline.

Someone left the company - what now?

Today - remove them from the work groups like any participant. The company console will add device revocation: the person's devices are disconnected from work groups in one step.

Which devices does it run on?

iPhone and iPad with iOS 18. Mac is in App Store review. Android and Windows are in testing.

How much does it cost?

The app is free for everyone. Terms for a dedicated server or deployment on your side are agreed separately - write to tysha@qbdp.online.

Has anyone checked the security?

What we checked, what we found and what we fixed is on the Security and Audit pages.
