1Key is a local-first password manager for Android. Your vault lives on your device, encrypted with a key only you hold, and never moves unless you export it yourself. There is no account to create, no server to breach, and no network connection of any kind — the INTERNET permission is stripped from the manifest, so the operating system itself enforces the offline guarantee.
