Quick answers
How do I cancel my subscription?
Subscriptions are managed by Apple, not by us. On your iPhone: Settings → your name → Subscriptions → Proof28 → Cancel. Cancel at least 24 hours before your renewal date to avoid being charged. Deleting the app does not cancel a subscription.
How do I request a refund?
Because Apple processes all payments, refunds go through Apple. Visit reportaproblem.apple.com, sign in with your Apple ID, and select the Proof28 purchase.
How do I delete my account and data?
Email us at support@proof28.com from the address on your account and we'll permanently delete your account data within 30 days, as described in our Privacy Policy. Photos are stored on your device, so deleting the app removes them.
My photos look misaligned between days — what happened?
Alignment works best when you use the ghost overlay each day: line your face up with the faint Day 1 outline before capturing. Distance from the camera matters most — try to keep your phone at the same arm's length each day, in similar lighting.
The AI analysis says it couldn't compare my photos.
This usually means one of the photos was too dark, blurry, or your face wasn't clearly visible. Retake the photo in even, natural light facing a window if you can, and try again.
Is my data safe? Where do my photos go?
Your daily photos stay on your device — they're never uploaded to our servers. Photos are only transmitted when you run an AI analysis, and only the photos involved. Full details are in our Privacy Policy.
I found a bug — what should I tell you?
Brilliant, thank you. Email us with: your iPhone model, your iOS version, what you were doing when it happened, and a screenshot if you can. That's usually everything we need to fix it fast.
