Good questions.
Why does ScreenGuard need Screen Time access?
Blocking apps on iPhone is only possible through Apple's Screen Time framework. When you allow access, ScreenGuard can shield the apps you choose. See the privacy policy.
What is a lock?
A lock is a group of apps and when they're locked. There are three kinds: for a set time (now, or automatically at set times), all the time (with short Breaks when you need one, and optional free times like lunch), and a daily time limit (one shared amount of time a day for the group).
What is a Break?
A Break opens the apps of an always-on lock for a few minutes, after a short breathing pause, and locks them again automatically. You choose how many Breaks you get a day.
What does Strict mode do?
Strict mode (Pro) is for locks with an end time, up to 24 hours. A strict lock can't be ended early, paused, weakened or interrupted by a Break in the app until it ends by itself.
How do I cancel a subscription?
Settings › your name › Subscriptions › ScreenGuard Pro › Cancel Subscription. You keep Pro until the end of the period you paid for.
