Privacy at a Glance
Every Specter account has a privacy tier that controls who sees your data.
| Tier | Your Stats | Your Location | Best For |
|---|---|---|---|
| Ghost | Trust circles only | Never shared | Maximum operational security |
| Stealth | Public | Trust circles + explicit grants | Share performance, protect routes |
| Social | Public | Explicit grant per activity | Selective sharing with control |
How Location Privacy Works
GPS tracks are AES-256 encrypted at rest. Start and end coordinates are jittered by up to 500 meters to prevent home/office inference. Route data is only accessible via an explicit, revocable ShareGrant — default is deny.
