About the local storage test:

• localStorage - persistent data storage (survives closing the browser)
• sessionStorage - temporary data storage (cleared after closing the tab)
• IndexedDB - a full-featured in-browser database for large amounts of data

Important: The tests will write and delete test data in your browser. All test data is automatically cleared after testing.

Note: Some browsers may have restrictions on using IndexedDB in private mode.

* IndexedDB can use up to 60-80% of the available disk space, but no more than 50GB in most browsers.
