+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Implement a non-binary privacy system where location and presence information is shared at different precision levels based on trust circles.
+
+Trust circle levels (configurable):
+- Intimate: Exact coordinates, real-time updates
+- Close: Street/block level precision
+- Friends: Neighborhood/district level
+- Network: City/region only
+- Public: Just "online" status or timezone
+
+Features:
+- Per-contact trust level configuration
+- Group trust levels (share more with "coworkers" group)
+- Automatic precision degradation over time
+- Selective disclosure controls per-session
+- Trust level visualization on map (concentric circles of precision)
+- Integration with zkGPS for cryptographic enforcement
+- Consent management and audit logs
+
+The system should default to maximum privacy and require explicit opt-in to share more precise information.
