Data Storage
All data is persisted in the browser's localStorage. No server or database is required.
localStorage Keys
| Key | Contents |
|---|---|
grafik-shared | Employee list (persists across months) |
grafik-{YYYY}-{MM} | Shifts, overtime, notes, norm overrides for a given month |
grafik-current | Last viewed year/month |
Export & Import
Data can be exported to a JSON file via the export menu. This allows you to:
- Create backups — export before making large changes
- Transfer data — import on a different computer/browser
- Manual editing — view and modify raw JSON

Important
Heads up — local data
localStorage data is tied to a specific browser and domain. Clearing browser data will delete all schedules.
Regular backups
We recommend regularly backing up via the JSON export feature, especially before the end of each month.
