Sextant

Where is everyone?
Others join through a link you send them — no code to type. Nothing to install, works in the browser on iPhone and Android. Positions are encrypted, the server can't read them.

How are you moving today?

Your group is ready

Send this link to the people you want in the group
…
🛡 Anyone who opens the link is in the group and sees everyone's position. Only send it to people you want there — the channel you send it through (SMS, WhatsApp…) sees it too.
🔒 The link carries the group's 256-bit key. It never reaches the server (it's after the "#"), so the server never sees positions. The group self-expires after 12 h of inactivity.
