Offline architecture
No cloud
On-device data, zero outbound paths
- Network disabled: remove network permissions to eliminate cloud leakage.
- Local database: SQLite / SwiftData keep text, tags, relations on-device.
- Zero tracking: no accounts, SDKs, analytics—privacy-first by default.
- Verifiable: no cloud logs or third-party calls; 100% offline solution.
