Optional website analytics
This website uses optional Google Analytics through Firebase to understand page visits and clicks on Google Play links. If you allow it, Google can process browser and device information, usage events, identifiers and approximate location derived from network information. Analytics can use cookies or browser identifiers.
The Analytics SDK is loaded only after you allow it. Your choice is stored locally in your browser. Use “Analytics preferences” in the footer to change it. Browsing and Play Store links work without Analytics. The website configures page and referrer URLs without query strings or fragments.
Mobile app learning data
The app stores selected level, quiz history, Academy progress, study plans, reminder preferences and related learning state locally. Downloaded study PDFs can be cached on the device. The current dependencies do not include Firebase Analytics or Google Mobile Ads in the mobile app; website analytics settings apply to this website only.
Online resources and external services
Study resources can use YouTube and remotely hosted PDFs. Opening or loading an online resource sends requests to its provider, which processes network information under its own policies. Google Play handles app downloads. Hosting providers process network requests to serve this site. See Google’s Privacy Policy and Google Analytics privacy information.
Choices and local data
You can decline website Analytics, change the choice in the footer, or clear site storage in browser settings. Notification permission can be managed in device settings. Clearing app storage removes locally saved learning state and may remove cached resources; backup behavior varies by device. Clearing local data does not automatically remove data already processed by external services.
