Precise location
Local map cells
Private identity key
Computed and protected locally. These values are not placed in network requests.
Private social presence
Put your

Explore when mutual friends may be nearby. The current pre-release app keeps coordinates and raw map cells on the device while acknowledging the metadata and malicious-friend limits that remain.
Private prototype · iOS and Android development builds
Coordinates and raw map cells stay client-side.
Presence is deliberate, bounded, and still pre-release.

Coordinates stay on your device.
Precise location
Ephemeral service
Token equality
Timing metadata

Made for deliberate presence.

Put your hat on
Nearby matching runs for one finite hour, then turns itself off.

Send a small encrypted invitation when a friend matches nearby.
A private signal for
real-world friendship.
