Latch support
Latch: Focus Lock & Blocker for iPhone.
Contact
Email goapps500@gmail.com. Please include your iPhone model and iOS version. In Latch, More › Protection health › Export diagnostics makes a text file you can attach; it contains no app names or personal data.
Blocking is off
Open Latch and go to More › Protection health. If Screen Time access is off, tap Fix and allow it. Latch cannot block anything without it.
Purchases
To restore Pro on a new iPhone, open the paywall and tap Restore. Subscriptions are managed and cancelled in Settings › Apple Account › Subscriptions.
What Latch cannot do
Like every iPhone blocker, Latch works within Apple's Screen Time rules. Resetting the Screen Time passcode, turning off Share Across Devices or erasing the iPhone removes its blocks. Latch tells you this in the app instead of pretending otherwise.
