Manage or cancel your subscription

NIX Pro is billed through your Apple account, so it is managed there rather than in the app:

• Open the Settings app on your iPhone
• Tap your name at the top, then Subscriptions
• Select NIX to change your plan or cancel

Cancelling stops the next renewal. You keep Pro access until the end of the period you have already paid for. To avoid being charged, turn off auto-renewal at least 24 hours before the period ends.

Restore a purchase

New phone, or reinstalled the app? Open NIX, go to the You tab and tap Restore purchases, signed in with the same Apple ID you originally purchased with. Your Pro access will come back automatically.

Delete your data

Your quit data lives encrypted on your device, not on our servers — there is no account to close. You can erase it in either of two ways:

• In the app: the You tab → Start over. This wipes your plan and history. There is no undo.
• Delete the app: uninstalling NIX removes all locally stored data with it.

See the Privacy Policy for the full detail on what is and isn't stored.

Common questions

The AI coach isn't responding. Check your internet connection first — the coach needs one. If you're connected and it still fails, the app falls back to offline coping guidance so you're never left without support. Email us if it persists.

I slipped and my plan looks wrong. That's expected behavior, not a bug. Logging a slip adjusts your plan and dips your Recovery Score by a few points. There's no reset and no penalty beyond that.

My notifications stopped. Check Settings → Notifications → NIX on your iPhone and make sure alerts are allowed. Reopening the app re-syncs your scheduled reminders.
