Delete your account

In Stiff, open the Profile tab, tap Settings, then Delete account. You confirm with your password, or with Apple if you signed in with Apple. Deleting is immediate and permanent: your scans, results, plan, routines, streaks, friends and reminders are deleted from Stiff’s servers, and there is no undo. What happens after that is in our Privacy Policy.

If you can’t sign in, email support@trystiff.com from the address you signed up with and we’ll help you delete it.

Your subscription

Subscriptions are billed by Apple, so Apple manages them. To change or cancel, open Settings on your iPhone, tap your name, then Subscriptions. Deleting your Stiff account doesn’t cancel a subscription: cancel it in Settings too. Refunds are handled by Apple at reportaproblem.apple.com.

Your data

To get a copy of your data, correct it, withdraw your consent to health data or ask anything about your privacy, email support@trystiff.com. We answer within 30 days (45 days for a request under a US state health data law). See our Consumer Health Data Privacy Policy and Privacy Policy.

Stiff isn’t medical advice

Stiff measures how you move and suggests stretches. It doesn’t diagnose, treat or prevent any condition. If you have pain, an injury or a health condition, check with a doctor before you start, and stop any stretch that hurts.
