Know your score.
Then move it.

Correct. The scoring model is bundled inside the app and runs on your iPhone's Neural Engine, so your face is measured and scored on the device and there is no code that would send the photo or the measurements anywhere. We do run a server for your account and progress, but your face never reaches it. The only way a photo of you leaves the device is if you tap Share yourself. You can verify the scoring is local: put the phone in airplane mode and scan. It works.

The model is trained on two public research datasets of faces rated by human panels, and it predicts how such a panel would rank a face. That is what it is — a statistical echo of other people's taste, learned from a few thousand faces. It is not an objective measure of you, and it is not a medical or psychological assessment. The datasets it learned from carry their raters' biases, so the model does too: we measure that per group instead of hiding behind one average, and it does not always come out well. Use the score as a training signal, not a verdict.

Overall is where your face scores today. Potential is where the model puts the same face with the things you can actually change — skin, hair, body fat, grooming, sleep — moved to their realistic best. The gap between the two is the part worth working on, and it is what the program is aimed at.

Because a face doesn't change in a day, but your lighting does. Scan daily and you measure the weather, not yourself — the number bounces and you quit. A week is long enough for a real change to clear the noise, often enough that you're still paying attention.

Not for the daily work. Your daily habit plan stays free for good, and so do your progress photos, the time-lapse export, three starter guides and deleting your data. What the subscription buys is every number this app worked out about your face — your Overall, your Potential and the eight metrics — the full 30-day program, points and streaks, and the per-metric deltas each week. We would rather you read that here than discover it after you've scanned your face. Any free trial is Apple's own introductory offer, shown on the purchase screen before you confirm. The subscription renews automatically, the price is always shown before you buy, and you cancel in your Apple settings in two taps. Full terms are here.

Settings → Erase all data wipes every photo, score, check-in and streak from your phone in one tap. Your photos and scores live only on your iPhone, so that is all it takes for them. For the anonymous account and progress we sync, Settings → Delete account hard-deletes it from our live systems at once; short-term encrypted backups hold a copy for up to about four weeks, then it is gone. Deleting the app removes the on-device data; use Delete account first if you want the server side gone too.
