FAQ

Questions.

How does a Promise work?
Pick one app and how long to lock it. Lockdt uses Apple's Screen Time to block it until the time is up.
What happens if I break a Promise?
You get 20 minutes in the app, then the lock returns. On paid Promises, each break costs more than the last. No stakes Promises have free breaks.
Can I get a refund?
Purchases go through Apple. Request one at reportaproblem.apple.com.
Why did my Break button disappear?
Lockdt needs Screen Time access to work. Turn it back on in Settings → Screen Time → Apps with Screen Time Access → Lockdt. Break is also hidden in the last minute of a Promise.
