Important: Clearing browser data, deleting the installed web app, or losing the phone may remove locally stored measurements. Keep a recent backup somewhere outside the app.
Create a full backup
- Open Body Stats and go to Settings.
- Choose the full backup/export option.
- Save the JSON backup in Files, Google Drive, Dropbox, or another location you control.
- Check that the file appears in the chosen location before clearing data or changing phones.
A full JSON backup includes measurements, profile and settings, and goals.
Move to a new phone
- Create a fresh full backup on the old phone.
- Install Body Stats on the new phone.
- Transfer the backup file to the new phone using a service you trust.
- Open Settings in Body Stats and choose Import or Restore.
- Select the backup and confirm that Dashboard, Log, Progress, Goals and custom labels look correct.
CSV exports
CSV is useful for opening measurement data in spreadsheet software. Use the full JSON backup—not CSV—when you want to restore the complete app state.
How often should I back up?
Back up after important measurement sessions and before changing phones, clearing browser data, reinstalling the app, or importing another file.
