GeoLock is a City of Hats feature that locks encrypted messages to a specific geographic location. The recipient can only decrypt and read the message when their device confirms they are physically within the designated area.

How does location-gated decryption work?

When you send a GeoLocked message, you set a location and radius. The message is encrypted with a location-bound key. The recipient's device checks their GPS coordinates against the geofence — only when they are inside the boundary does the decryption key become available.

Does City of Hats track my location?

No. Location verification happens entirely on the recipient's device. City of Hats servers never receive, store, or process GPS coordinates. The geofence parameters are encrypted alongside the message.

Can I set any location and radius?

Yes. You can drop a pin anywhere on the map and set a custom radius. The recipient must be within that radius to unlock the message. Radius options range from a few meters to several kilometers.
