Questions
Can I always get into my apps?
Yes. Breaking a seal or Emergency unlock always opens them, even in Strict mode. It just costs you a piece.
What does Walnut see?
Nothing inside your apps. It uses Apple’s Screen Time, and the list of apps you lock never leaves your phone.
What if I delete Walnut?
Every lock is removed with it. Nothing stays locked.
Do I need an account?
No. There is no sign-up. Your progress lives on your phone.
