About this app
KitchenLocker holds a combination for you and will not hand it back early.
You put whatever you are taking a break from into a box — a bottle, a pack, a console, a second phone — and shut it with an ordinary combination lock from any hardware shop. You save the digits here and set a timer. They stay hidden until it ends, even from you, unless you set up a way out first.
There is no motor, no Bluetooth, no clever hardware. The app's only moving part is refusing to answer.
Three kinds of lock
• Manual — stays shut until a date and time you pick.
• Recurring — opens once per period, a day or a week, then shuts again on its own schedule.
• On demand — stays shut indefinitely. Ask for it and a delay you chose in advance starts running: the time your resolve gets to change its mind. Asking can be cancelled. The delay cannot be hurried.
What it will not do
• Shorten a timer. A wait that can be talked down is not a wait. A running lock offers one adjustment: staying shut longer.
• Release the digits on the way out. Delete a lock and the combination stays sealed, waiting in Recently deleted for 30 days.
• Fall for the clock trick. Setting your phone forward does not open a lock early; setting it back does not stretch one out.
Two early exits, both set up before the lock shuts. A backup code: ten single-use codes, shown exactly once. Write them down somewhere outside the box. Spending one opens that lock on the spot, and your streak starts over. Or a partner you invited says yes, and your streak stands.
It runs on your phone
A timer is arithmetic against a saved time, not a process. Force-quit the app, switch on aeroplane mode, run the battery flat overnight — none of it moves an opening. Notifications are scheduled with the system, so your phone tells you when time is up whether the app is running or not. No connection required, and no account either unless you want sync or a partner.
Sealed before it leaves
Turn sync on and lock names, combinations, memos and history are sealed on the phone before they go anywhere, with a key that travels between your devices in envelopes no server can open. A new phone joins only when a phone that already syncs, or your recovery code, admits it — a password on its own is deliberately not enough. The service can see that a lock exists and how its timer runs. Not what it is called, unless you choose to share that, and never the digits.
An optional fingerprint, face or passcode gate keeps combinations and countdowns off the screen when somebody else is holding your phone.
What the app keeps
Every lock, every opening and every backup code spent lands in an activity log you can read back. The stats screen counts the hours you have held, your current streak, and how the weeks compare. A split-flap countdown on the home screen makes the wait harder to ignore.
What never goes in the box
Anything living, first and always. After that: medicine, spare keys, documents, anything you might need in an emergency, and anything you cannot afford to lose. Combinations get lost, and no system is perfect. Shut every box on the assumption that it might stay shut.
What it costs
Free with up to two locks shut at once. Sync, history and monthly reports are free for everyone, and will stay free. Pro is a subscription, by the 3 months or the year, that lifts the cap and adds on-demand locks. Nothing that opens a lock is ever charged for.
KitchenLocker is a commitment device, not a vault door. It works because you decided it should, and it keeps working after you change your mind.

Lock it in a box. The combination comes back when the timer says so.
