Walk to clear the fog. A friend sends you a place and you do not get a pin — you get a mood, a climb, and a glimpse through the trees. The map stays misted until you stand there and walk it.
Walk to uncover your map and share a mystery with people you trust. Real Circle friends are accepted by you; there is no public feed, global board or chat.
Signing in alone does not upload your walking. Optional statistics sync and route sync are separate choices, off by default; routes exclude protected areas. Place sharing sends the package you choose, and notifications are optional. Read the Privacy Policy for what each choice transmits.
There are no analytics, advertising or tracking SDKs. FogTrail Pro subscriptions are handled by Apple.
FogTrail points at real places, but the routes, notes and stills inside it are illustrative examples — not a survey, and not navigation. Read Walking safely before your first walk.
