Field notes
Group setup is described as exchanging a random key through a QR code or link rather than relying on an account or central trust broker. The homepage says last-seen details remain in memory for up to six hours, and that users can decline location and use a hot/cold fallback. These are descriptions on the site, not independent tests of the app's performance.
