ricof30/sylo ? reverse-engineered prompt

Build me a local only Android password manager called Sylo.

It should let me save logins, cards, crypto seed phrases, API keys, and other sensitive notes in an encrypted vault that stays on the device only. I want the app to lock with fingerprint or a PIN every time I open it, auto lock after a while, and support Android autofill so it can suggest saved credentials in apps and websites. Include a password generator, a simple safety score for weak passwords, and an optional breach check using Have I Been Pwned. I also want encrypted backup and restore, custom icons for entries, dark, light, and system theme support, and a clean monochrome look that works well on phones and tablets.

Keep it simple, secure, and polished. If you need current Android docs or best practices, look them up online.
