01
Assessments are temporary
Answer choices and the current score are held only in JavaScript memory while an assessment is open. Reloading or closing the page removes that temporary result. The assessment engine does not use local storage, cookies, a database, or a network request.
02
Appearance is remembered locally
The selected color theme and page style may be stored in this browser under the keys mathExplorerTheme and mathExplorerStyle. These values describe only page appearance and are not assessment data.
03
Offline files may be cached
On supported browsers, a service worker may cache public app files—HTML, CSS, JavaScript, icons, and the local math renderer—so visited content can load more reliably. The cache contains app resources, not student answers.
04
You can remove local information
Use the browser’s “clear site data” or storage settings to remove the appearance preference and offline cache. The app will return to its default appearance and can rebuild its public-file cache on a later visit.
