What local saving means
Tournament state is stored in IndexedDB in the browser profile you are using. That supports Auto Save and refresh restore on the same browser when the local record remains available. It does not upload the tournament to a BracketMetrik account or cloud database.
What it does not guarantee
BracketMetrik is not currently an installed PWA and does not register a Service Worker. Reopening the site normally requires the browser to retrieve application resources from the web. Do not assume that a previously opened page will load again, or that every feature will continue working, without a network connection.
Use JSON backups for portability
A downloaded JSON backup is more reliable than treating a browser cache as permanent offline storage. Export a current backup before travel, venue setup, browser maintenance, or device changes, and keep a copy somewhere you control. Import still requires BracketMetrik to be open and able to run in the browser.
Before an event
- Open the product and confirm the tournament restores correctly.
- Export and inspect a current JSON backup.
- Keep a printed copy or Save-as-PDF copy when appropriate.
- Plan for reliable network access to reopen the web application.
