In 2018, Strava's heatmap exposed military bases worldwide. The choice today is: accept the exposure, or stop tracking entirely. Specter is built for the people who refused both options.
GPS data is AES-256 encrypted at rest. A database breach exposes nothing.
Patent-pending route transposition. Run laps at home, share laps in Lisbon.
Ghost, Stealth, Social. Cryptographically enforced sharing controls.
iOS, Android, Apple Watch, Wear OS, and Garmin. One account, every device.
Per-person, time-limited grants. Stats-only, fuzzy route, or full route.
Delete means overwrite with random bytes. Not a database flag, actual destruction.
