Naamly stores everything on your device and keeps no copies anywhere else, so deleting your account and data is fully in your hands:
- To keep a copy first: Settings → Export data (JSON, shared via the share sheet).
- Sign out (if you used Sign in with Apple) from the Profile screen.
- Delete the app from your device. This permanently removes all Naamly data — mantras, counts, history, achievements, settings, and your profile photo.
- Optionally, stop sharing your Apple ID with Naamly: iPhone Settings → your name → Sign-In & Security → Sign in with Apple → Naamly → Stop using.
There is nothing to delete on any server, because Naamly has no servers and never receives your data.
