Deleting your account
Updated 12 September 2026
From the app, in three steps
Open Vitality, go to Settings, scroll to Account and tap «Delete account». The app asks for confirmation and, if you signed in a while ago, to sign in again: that stops anyone deleting an account from an unlocked phone.
Without the app
If you no longer have the phone, or the app will not open, write to vitality@gowithzefyr.ch from the address you registered with. We verify your identity and delete within thirty days.
What is deleted
Your profile, biometric measurements (sleep, recovery, strain, heart rate, ECG), coach conversations, goals and journal. Deletion is permanent: we keep no copy to restore from.
What stays, and for how long
Only what the law requires us to keep: purchase invoices, for ten years, under Swiss law. They contain no health data. Anonymous technical logs, which cannot be traced back to you, are kept for at most ninety days.
When
From the app, deletion is immediate. By email we carry it out within thirty days of verifying your identity, and we write to you once it is done.
