## 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.
|

## Implementation Notes
|
|
|
|
<!-- SECTION:NOTES:BEGIN -->
|
|
**TypeScript foundation completed in task-029:**
|
|
- TrustCircleManager class (src/open-mapping/privacy/trustCircles.ts)
|
|
- 5 trust levels with precision mapping
|
|
- Per-contact trust configuration
|
|
- Group trust levels
|
|
- Precision degradation over time
|
|
- Integration with zkGPS commitments
|
|
|
|
**Still needs UI components:**
|
|
- Trust circle configuration panel
|
|
- Contact management interface
|
|
- Visual concentric circles on map
|
|
- Consent management dialog
|
