Browser data is fragile. Your data will be erased if you clear browser history or use incognito mode. Export regularly — it's your only backup.
Privacy: all data stays on this device only.
Download all your cars, maintenance logs, accessories and issues as a JSON file. Use this regularly as a backup — your data only lives in this browser.
Restore from a previously exported JSON file. This will overwrite your current data.
Only files exported from this app will be accepted. Make sure the file ends in .json.
All your cars and service records are saved directly in your browser's localStorage. No account required, no server involved.
Your data never leaves your device. It cannot be accessed by us or anyone else. What you log stays yours.
Because data lives only in your browser, clearing site data or switching browsers will erase it. Use Export regularly to keep a safe copy.
Exported files are plain JSON — human-readable and easy to inspect or migrate. You can re-import them any time.
Permanently erase all your cars and maintenance records. This action cannot be undone. Export your data first if in doubt.
