Visit posec.pages.dev or install the Android APK. No account linking, no phone number.
Choose any username. Your device generates a unique key pair — your cryptographic identity.
Write down your 12-word phrase. This is the ONLY way to recover your account. We can't reset it.
Yes, completely free. Encrypted messaging, groups, channels, Hangout, and Arena are all free. Optional premium features coming later.
We're submitting to Play Store soon. Until then, the APK is signed and safe to install directly. Your device may show a warning — this is normal for non-Store apps.

Signal requires a phone number. PoSec uses key-pair identity — no phone, no email, fully anonymous. Plus we have social features (Hangout, Arena) that Signal doesn't.
