Download for Android
After installing once, the app updates itself from inside —
you never need to download from this page again.
How to install
1
Tap “Download for Android”. The file downloads to your phone (about 47 MB).
2
Open the downloaded file (swipe the notification, or look in Downloads).
Android will ask to allow installs from your browser — tap Allow. This is normal for apps
outside the Play Store.
3
If Play Protect appears (“Scan app recommended”), tap
Scan app, wait for the scan, then Install. The app is safe — it's ours.
4
Sign in with your Google account or email. Then share your
8-character code from Profile with family to start chatting.

Voice & Video Calls
Encrypted calls, peer-to-peer. Group calls too.
Group Chats
Family groups with encryption for every member.
Photos & Voice Notes
Share encrypted photos, files and voice messages.
