aload0/AppLock — reverse-engineered prompt

Build me a polished Android app locker focused on privacy. I want a simple app where I can see the apps installed on my phone, choose which ones to lock, and then require biometric unlock or a PIN before those apps open. It should feel modern and clean, match the phone theme with a Material You style, and be fast and lightweight.

Please include useful privacy features like background protection so locked apps stay protected, an unlock timeout so I do not have to re enter my PIN every second, and anti uninstall protection if possible. Everything should stay on device and it should work without root. Make the setup flow easy for normal people, including permissions and a clear explanation if overlay access is needed and why.

I would also like a settings screen, a first run intro, and a nice lock screen for entering the PIN or using fingerprint or face unlock. If anything is unclear, look up current Android docs online and make sensible choices.
