XCoord

XCoord is a privacy-first live location sharing app for small groups — families, hiking trips, friends meeting up at a festival, parents tracking each other on a school run. WHY XCOORD IS DIFFERENT • End-to-end encrypted. The server only ever sees encrypted location blobs. Decryption keys are derived from your invite code, which never leaves your device once the group is created. • No accounts. No phone number, email, or social login. Just a display name you can change anytime. • Self-dissolving groups. Pick 1–15 days when you create a group; it auto-deletes when the timer ends. • One group at a time. Keeps things simple — no notification storms. HOW IT WORKS 1. Create a group → share the QR code or 10-character invite. 2. Friends scan or paste; everyone shows up on the map. 3. Move around — your dot follows you, theirs follows them. 4. Group expires (or you leave) → server forgets you exist. PRIVACY HIGHLIGHTS • AES-256-GCM encryption (industry standard, used by Signal, WhatsApp). • Invite codes are hashed before reaching the server — even if our database is stolen, attackers can't decrypt anyone's location. • Open privacy policy. We don't sell data. The only third-party SDK is Google AdMob (banner + occasional rewarded ads). GREAT FOR • Family meetups in unfamiliar cities • Hikes, festivals, conferences • Parents tracking school pickups • Friends finding each other at a venue PERMISSIONS • Location (always) — to share your dot with the group, even when the app is backgrounded. • Notifications — for the foreground service indicator. • Camera (optional) — to scan invite QR codes.
