Tether keeps your group aware of each other during events — a stadium, a festival, a night out. One QR code scan tethers the group. When the event ends, every breadcrumb evaporates.
Why Tether
Every other tracking tool assumes you want to be watched forever. Tether assumes you just need a few hours.
Draw a radius around your venue. Anyone who drifts outside gets an alert — and so does their buddy.
The host shows a QR code. Friends scan it. Done. Nobody creates an account or joins a permanent circle.
Users are paired. Yellow alert when someone drifts, orange when they're out more than 3 minutes, red SOS if their battery hits critical.
You set a timer. When it hits zero, all tracking stops and every location breadcrumb is erased from our servers. No trail left behind.
We use OS-level location triggers, not constant GPS polling. Tether won't eat 20% of your battery during a 6-hour event.
iOS and Android in one group — no "blue bubble" problem. Everyone sees everyone, regardless of their phone.
How it works
Name it, set a radius on the map, and choose how long it lasts — 2 hours to 12.
One scan joins the group instantly. No app account needed for guests.
Everyone sees each other on the shared map. Alerts fire if anyone drifts outside the zone.
Timer hits zero. All location history is wiped. No permanent record of the night.
Who uses Tether
Privacy
Tether is a utility, not a social network. We have no interest in your data beyond keeping your group safe for a few hours.
Awareness, not surveillance. Only the members of your active event can see your location — never us, never advertisers.
Breadcrumbs evaporate, not monetize. No marketing use, no data brokers, no third-party trackers — ever. Location data is wiped when your event ends.
Opt-in every time. Tracking is active only during an event you choose to join. A persistent banner on your phone tells you when sharing is live.
Download Tether and set your first halo in under a minute.
