Data & Storage
End-to-end
encrypted. Always.
Your sessions belong to you. Here's exactly what that looks like under the hood.
How your data is protected
AES-256 end-to-end encryption
Every message, breath log and session note is encrypted on your device before it ever leaves it. The key never leaves your phone.
Zero-knowledge servers
Our servers store ciphertext only. We can't read your conversations even if we wanted to — and we have audited proof we can't.
No third-party trackers
No Google Analytics, no Meta pixel, no ad networks. We don't sell, share or rent your data — full stop.
You choose where it lives
On-device only by default. Optionally sync an encrypted backup to iCloud or your own server.
