Enso is made by one person. Write to me and I'll answer.
I usually reply within two business days. If something is broken, telling me your iPhone model and iOS version saves us a round trip.
If you leave Enso and stay away for more than 30 seconds while a session is running, it's marked abandoned and no tree is planted. Locking your phone is fine — that counts as meditating, and the session keeps running. This is deliberate rather than a bug: sitting with the phone down is the whole point.
Tap Restore purchases at the bottom of the purchase screen, making sure you're signed in with the same Apple Account you bought with. If it still doesn't unlock, email me — include the Apple receipt and I'll sort it out.
On your iPhone: Settings → your Apple Account → Subscriptions → Enso → Cancel Subscription. Apple handles all billing, so cancelling and refunds go through them, not me. Cancelling stops future charges and you keep access until the current period ends.
Menu → Delete My Data permanently wipes every session and preference on your device. Deleting the app does the same thing. There's no copy on a server to delete, because nothing was ever sent to one.
No. Sessions, streaks and your forest stay on the device. The only thing sent anywhere is anonymous usage analytics, which you can turn off under Menu → Anonymous Analytics. Full detail in the privacy policy.
Refunds are handled by Apple at reportaproblem.apple.com. I can't issue them myself, but if something about Enso didn't work, tell me — I'd like to fix it.
Bugs, feature ideas, or a session that went wrong — email me. There's no ticket system and no bot on the other end.
