Local-first data ownership
All your data lives in a Room database on your device. No cloud sync.
Summary
Profiles, shot logs, calibration offsets, gear, all stored in a Room SQLite database on the device. No cloud sync, no server-side copy, no account required.
How it works
What this means
Your shot log, your gear, your custom film stocks, your calibration offsets, all live in a single SQLite database file in the app's private storage on this device. There is no cloud sync, no account login, no server-side copy. If you uninstall the app, the data goes with it. If you back up the device, the data is in your backup.
Why
Most logging apps treat the user's data as something to ingest and lock behind an account. The model here is the opposite: this is a tool you own, and the data it records is yours, on hardware you own, in a format that survives the app shutting down (SQLite is open and forever-readable).
How to move data between devices
Today the path is the system-level Android backup (Google Drive auto-backup, or vendor-specific backup for Samsung/Sony/etc.) which captures the database with the rest of the app's data. Future direct export/import (file-based) is on the roadmap but not in scope yet.
