FAQ
Honest answers.
On Android, the system won't let an app reliably know when another app comes to the foreground without it. We use the Accessibility Service only to detect the moment a blocked app opens, so the quiz can appear instantly. We do not read what you type, screen content, passwords, or notifications. (On iPhone, LLLock uses Apple's Screen Time framework instead — no Accessibility access.)
The blocking and quiz loop is fully offline. Cards, decks, statistics, settings — all stored locally on your device in the app's private storage; uninstall and it's wiped. Only AI generation and photo-to-card need a connection (they call OpenAI). No account, no cloud sync.
The free tier has limits; full AI generation and photo-to-card unlock with the yearly subscription. When you use it, your prompt goes directly to OpenAI for processing — we do not store it.
Android: Google Play → your profile → Payments & subscriptions → Subscriptions → LLLock → Cancel. iPhone: Settings → your name → Subscriptions → LLLock → Cancel. Either way it takes effect at the end of the current billing period, and uninstalling the app does not cancel it.
Almost. Anything you can launch from your home screen — social, games, news, dating, video, even web browsers. System apps like Settings and Phone are off-limits to keep your phone usable.
Yes — LLLock is on the App Store for iPhone and on Google Play for Android. Same idea on both: pass a quick quiz to unlock a blocked app. The under-the-hood blocking differs per platform (Accessibility on Android, Screen Time on iPhone), but the experience is the same.
