Telling us your iOS version and roughly when the problem happened is usually enough for us to find it. Screenshots help. Please do not send passwords; we will never ask for one.

Lerin reads what is visible in a photograph. It is a cosmetic app: it does not diagnose, and it is not a medical device. If something on your skin worries you, please see a doctor or a dermatologist.

Scores move with lighting, angle, and time of day as well as with your skin. Scan in similar conditions each time and the comparison between scans means more. If a scan looks wrong, retake it in better, even light with your face unobstructed.

Your next check-in date is set by your plan, and face scans stay closed until it arrives. That is deliberate for every subscriber: skin does not change meaningfully day to day, and scanning more often would only measure the lighting.

Subscriptions are billed by Apple through your App Store account, not by us. Manage or cancel one in Settings → your name → Subscriptions on your iPhone. Cancelling stops the next renewal and you keep access until the current period ends.

Refunds are handled by Apple, not by us, at reportaproblem.apple.com. If a charge looks wrong, write to us anyway and we will help you work out what happened.

You can delete your account and everything in it from inside the app, under Settings. Deleting removes your scan photographs and the readings derived from them. It is permanent, and we cannot restore a deleted scan.

What we collect and why is set out in the Privacy Policy. Residents of states with dedicated health-data laws should also read the Consumer Health Data Privacy Notice. The Terms of Service cover the rest.
