How can we help?

Subscriptions are billed and managed entirely by Apple through your Apple ID — we can't cancel it for you, but you can do it yourself in under a minute: open Settings → [your name] → Subscriptions → CaffCurve, then tap Cancel Subscription. You'll keep full access until the end of your current billing period. Full details: Apple's subscription management guide.

If you've reinstalled CaffCurve or switched devices, open the app and go to Profile → Subscription, then tap Restore Purchases. Make sure you're signed into the same Apple ID you originally subscribed with — Apple, not us, is the source of truth for your subscription status.

In the app, go to Profile → Sync & Data → Delete All My Data. This permanently deletes your caffeine logs, custom drinks, streaks, and settings — from your device, and from iCloud if you had Sync turned on. Your subscription and Apple ID aren't affected, since we never had access to either. Uninstalling the app has the same effect on locally stored data. We hold no copy of this data ourselves, so there's nothing further for us to delete on our end — see our Privacy Policy for the limited, anonymous subscription analytics we do keep, and how to have those removed.
