Let the kids play. Your vault stays locked.

Not from the pattern screen: the pattern screen has no delete button, and wrong tries never erase anything. Deleting a vault happens inside that vault, after that vault’s pattern is drawn again. Your kids could delete the whole Underlock app from your Home Screen, which deletes the vault on this iPhone. Guided Access keeps your kids in one app.

After 5 wrong tries, Underlock makes your child wait: 30 seconds, then 1, 5 and 15 minutes, then an hour each time. Nothing is ever erased for wrong tries. If you think your child has learned your pattern, change your pattern.

With Pro, the next time you open your vault, Underlock shows when someone tried, how many times and, if you turn it on, a photo of who it was.

Not photos in your vault. Photos in your vault aren’t in the Photos app, so iCloud Photos doesn’t show them on the iPad. If the iPad uses your Apple Account and iCloud Photos, your Hidden album shows on that iPad too, behind the iPad’s own lock.

Yes. Underlock is free forever: one vault, no file limit. If the free plan ever changes, you keep the plan you started with. More vaults come with Pro, Underlock’s paid plan.
