--- id: task-032 title: Privacy Gradient Trust Circle System status: To Do assignee: [] created_date: '2025-12-04 21:12' labels: - feature - privacy - social dependencies: [] priority: medium --- ## Description 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. ## Acceptance Criteria - [ ] #1 Trust circle configuration UI - [ ] #2 Per-contact precision settings - [ ] #3 Group-based trust levels - [ ] #4 Precision degradation over time working - [ ] #5 Visual representation of trust circles on map - [ ] #6 Consent management interface - [ ] #7 Integration points with zkGPS task - [ ] #8 Privacy-by-default enforced
