What Makes a Note-Taking App Truly Private?
Core Privacy Principles
Data Minimization
Truly private apps collect the minimum data necessary for operation:
**No user accounts**: Anonymous usage without registration**No analytics**: Zero tracking of user behavior**No telemetry**: No automatic data transmission**Local processing**: All operations performed on-deviceUser Control
Privacy-focused apps give users complete control:
**Data ownership**: Users own all their data**Export capabilities**: Easy data portability**Deletion control**: Complete data removal options**Access management**: User-controlled security settingsTransparency
Private apps are open about their practices:
**Clear policies**: Straightforward privacy statements**Open source**: Code available for inspection**Regular audits**: Third-party security reviews**Communication**: Direct developer communicationComprehensive Privacy Comparison
