Essential storage makes practice work. Analytics preferences and advertising-provider privacy controls are separate.
What is stored?
| Storage | Purpose | How long |
|---|---|---|
| Local practice storage | Preferences, custom text, and completed session results. | Until reset or removed by you or your browser. |
| Local privacy choice | Remembers your optional analytics choice. Earlier versions also stored a separate advertising switch, which is no longer used; it is not converted into advertising consent. | Choices expire after 180 days, or earlier if you clear them. |
| Optional Analytics cookies | Measure website visits when Analytics is enabled and permitted. | Varies with the provider and account settings. |
| Optional advertising and consent storage | Consent management, ad delivery, measurement, and fraud prevention. | Varies with the provider and consent settings. |
Local storage and cookies are different
Local storage remains in your browser and is read by the practice application. It is not automatically attached to requests like a cookie. Optional services may use cookies, local storage, and other browser identifiers.
Change or withdraw a choice
Open Privacy choices to change optional analytics. You can decline analytics and still practice. Advertising may remain visible; use the advertising provider’s privacy controls for its data-use choices. To remove all browser-held information for this site, use your browser’s site-data settings. Export your practice progress first if you want to keep it.
