Email support@lockintwin.app and you'll get a reply. Include your phone number's country code and roughly when the problem happened — that's usually enough to find it.
Reporting something
Every photo, proof and written card in the app has a report control on it. Reports reach us directly and we review them within 24 hours. You can also end a deal at any time from Settings, which stops all further content from that person.
If something needs attention faster than the in-app report, email the address above.
Common questions
- My friend's invite link won't open the app. Install Lock In Twin from the App Store, then tap the link again. You can also open the app and enter the invite code yourself. Lock In Twin is iPhone-only for now.
- My friend hasn't confirmed my check-in. Check-ins confirm automatically after 12 hours. Silence counts as a yes.
- My check-in didn't count. Older Wake Up Early challenges only count check-ins taken inside the wake-up window you agreed. A photo taken outside it is saved but doesn't count, and the app says so at the time. Wake Up Early can't be chosen for new challenges.
- I can't take proof of my punishment. Punishment proof accepts a photo from your library as well as the camera, and the person owed the debt can close it out themselves. Check-ins are camera-only.
- How many challenges can I have? Up to three at once, each with one friend.
- Where are the re-roll credits I bought? They belong to your account, not your phone, so signing in with the same phone number brings them back. Your balance is in Settings → Re-roll credits. A credit redraws an upcoming card before its week starts; it can't change a result. Purchases go through Apple, so refunds are requested from Apple at reportaproblem.apple.com.
- I want my data. Settings → Export my data.
- I want my account deleted. Settings → Delete account. It removes your photos, your record and your account itself.
