Need help? Email Myappdeveloper371@gmail.com — My KC is built and supported by one person (who has keratoconus too), so you're writing to the actual developer. I aim to reply within a couple of days.
Retake the photo flat-on, with the whole page in frame, sharp and without glare — that fixes most misreads. Every AI-read value is editable before and after saving, so you can always correct a field by hand. Values it flags as "medium/low confidence" deserve a double-check against the printed report.
On your iPhone, and only there — there are no accounts and no cloud copy. That also means: if you delete the app, your data goes with it. Use Settings → Export backup first if you're switching phones or reinstalling.
Settings → Export backup on the old phone (save the file anywhere you like), then Settings → Import backup on the new one.
Tap Settings → "Restore subscription". If that doesn't unlock it, check you're signed into the same Apple ID that bought it, then email me.
Settings → Research → Withdraw stops all future contributions immediately. To have already-contributed data deleted, email me your contributor code (shown on the same screen) — it's the only identifier that exists, which is also why I can't recover it if lost.
No. My KC is a personal tracking aid. It cannot diagnose keratoconus, and its indicators are no substitute for your eye specialist's interpretation. If you're worried about your eyes, see your specialist.
