Managing your subscription

Hemi Premium is billed through your Apple ID, not by us directly, so changes are made in iOS Settings rather than in the app.

To view, change, or cancel your plan, open the Settings app on your iPhone, tap your name at the top, then tap Subscriptions and choose Hemi. Cancelling stops the next renewal and you keep access until the end of the period you have already paid for.

If you cancel during a free trial before it ends, you are not charged at all.

Restoring a purchase

If you reinstalled Hemi, changed phones, or are being asked to subscribe despite already having an active subscription, tap Restore purchases — it appears both on the subscription screen and in Settings inside the app. Make sure you are signed in to the same Apple ID you originally subscribed with, as subscriptions are tied to the Apple ID that bought them rather than to your Hemi account.

Refunds

Refunds for App Store purchases are handled by Apple, not by us. You can request one at reportaproblem.apple.com. If something went wrong on our end, email us anyway — we will help you make the case.

Your data

You can delete your account and everything in it at any time from Settings inside the app. Deletion is permanent and removes your logs, photos-derived estimates, and profile from our systems.

You can also generate a shareable report of your own data from the Report tab, which you can save or send to a clinician. For any other data request, email us and we will help.

Trouble signing in

Hemi supports email, Apple, and Google sign-in. If you first signed up with Apple or Google, use that same method again — signing in with a different provider creates a separate account and your existing data will not appear under it. If you are stuck, email us with the address you signed up with and we will sort it out.

Reporting a bug

Email us with what happened, what you expected, and roughly when it occurred. Screenshots help a lot. Reports go straight to the person who builds the app.
