ToddlerLock: Lock to One App

Hand your phone to your toddler without handing over your whole phone.

ToddlerLock locks your phone to one app. Your child watches the video or plays the game you picked, and everything else stays out of reach. No calls placed. No emails sent. No photos deleted. No in-app purchases.

HOW IT WORKS
Pick the one app your child gets. Tap Hand over. That app opens and the lock holds it there. If your child taps their way out, ToddlerLock brings them straight back. The notification shade stays shut. To release, you press and hold, then slide.

That is the whole product. It takes about three seconds, one handed, which is roughly how long you have.

WHAT IS FREE, FOREVER
The lock itself is free and always will be. That includes:

Lock to one app, with automatic return if your child leaves it
Max Lock, which uses Android's own app pinning for a stronger hold
Slide to release, so a toddler cannot get out but you can
A twenty minute session timer
Adjustable hold length

No ads. Core locking and the permanent free features need no account or sign-in. Optional Google sign-in connects an eligible 14-day Plus trial, referrals and purchase access.

WHAT PLUS ADDS
Plus is optional. If the free lock is all you need, keep it. Eligible adults can start a separate 14-day Plus trial with Google sign-in. No payment method is required, and the trial never charges automatically. Paid monthly and annual access starts only after you confirm a Google Play purchase. Lifetime is a separate one-time purchase.

Every session length, from ten minutes to an hour, plus custom
Release with your PIN or your fingerprint instead of the slide
A daily screen budget that caps the whole day, not just one session
Switchback and countdown timing you can tune

WHY PARENTS USE IT
A toddler on an unlocked phone finds the camera roll, the group chat and the app store within about ninety seconds. Android has screen pinning built in, but it is buried in settings, it behaves differently on Samsung and OnePlus, and a determined two year old can swipe out of it.

ToddlerLock is the version of that idea built for the actual moment: you are in a car, a waiting room or a queue, your child is already reaching, and you need the phone safe right now.

PERMISSIONS, PLAINLY
ToddlerLock needs accessibility access to notice when your child leaves the chosen app, and draw over apps to hold the lock in place. Android shows a strong warning when you grant accessibility access. That is Android being careful, not a sign anything is wrong.

While the lock is active, ToddlerLock reads the foreground app name so it can keep the chosen app open. It never reads what you type. Six account-unlinked usage counters are on by default, contain no identifier or chosen app name, and can be turned off in Settings. Optional account features send the disclosed Google account, device, purchase and qualifying-session records, without locked app names or screen content.

GOOD TO KNOW
Core locking and releasing work offline. Account trials, referrals and purchase sync need a connection.
Works on phones and tablets.
Max Lock affects incoming calls while active, so use it when that is acceptable.

Kid mode, child lock, baby mode, screen pinning: whatever you call it, this is the one that holds.
