The moment a blocked app opens, a lock overlay appears instantly — no delay, no workaround. Switch profiles from the notification bar or Quick Settings tile without even opening the app. Each profile switch requires a PIN, so kids can't switch to Personal mode when you're not looking. ━━━━━━━━━━━━━━━━━━━━━━━ 🛡️ FEATURES ━━━━━━━━━━━━━━━━━━━━━━━ ✔ App blocking — choose exactly which apps are allowed per profile ✔ Screen time limits — daily limit per profile, auto-locks when time is up ✔ Strict Kiosk Mode — single-app lock for Kids profiles ✔ Study lock — timed deep focus sessions that can't be interrupted ✔ Custom launcher — your home screen shows only allowed apps ✔ PIN protection — master PIN + optional per-profile PINs ✔ Quick switch — notification bar & Quick Settings tile ✔ Auto-restore — active profile survives reboots ✔ App widget — active profile at a glance ━━━━━━━━━━━━━━━━━━━━━━━ 🌱 PRIVACY FIRST ━━━━━━━━━━━━━━━━━━━━━━━ Profile Locker collects zero personal data. Everything stays on your device. No account required. No internet permission. No analytics, no ads, no tracking — ever. Your PIN is hashed with PBKDF2-SHA256 (310,000 iterations). Your profiles never leave your phone. Backups are explicitly disabled to keep your security settings safe.
