We usually reply within a day.
Write to us here, or from inside the app under Settings → Contact support. Sending from the app attaches your account, which lets us look up a portrait you're asking about.
No. A credit is only spent on a portrait that succeeds; if generation fails the credit is returned to your balance automatically.
Portraits are stored on your device, and accounts are anonymous, so deleting the app can end the link to your history. Write to us with the email you used to buy and we'll help.
Subscriptions are managed by Apple: open the Settings app, tap your name, then Subscriptions. You can also reach the subscription screen from Settings → Manage subscription in the app.
Use Settings → Delete my scans in the app to remove your portrait history. To have everything erased, send us a message here.
