SessionStorage will be deleted under the following circumstances:

1. When the user closes all windows or tabs related to the website, SessionStorage will be cleared. Because SessionStorage is bound to the session, it is only valid during the current session.

2. When the user actively clears the browser cache and data, SessionStorage will also be cleared. Clearing browser data usually includes clearing cache, cookies, etc., and session data will also be cleared.

3. If the page uses the "sessionStorage.clear()" method to clear the data in SessionStorage, all session data will be deleted immediately.

It should be noted that SessionStorage data is stored in the user's local browser and therefore cannot be shared across different browser instances or devices. Each browser instance has its own independent SessionStorage.
