Backup & restore
Your data is private by design — it lives in this browser only, never on our servers.
Clearing "Cookies and other site data" in your browser will erase all your data!
Export a backup file to keep a copy.
The backup JSON file downloads to your browser's default Downloads folder. File name starts with "renosheets-backup-".
Importing merges the file into what's already here — matching items are updated, the rest are added.
