Lock down your sensitive data with 256-bit AES-GCM encryption — the same standard trusted by governments and militaries. Store it anywhere, even on a shared device. Without the key, it's unreadable. Period.
Need to send something privately? Share the password separately — in person or via a different channel. Never alongside the message itself.
Everything happens on your device. No servers. No cloud. No exceptions. Turn off your Wi-Fi and watch it still work — that's how you know your data never leaves your hands.
