1. Essential storage
Essential cookies or local storage support security, CSRF protection, language, session continuity, authentication and saved consent choices.
2. Optional analytics
Optional analytics must stay disabled until consent is granted and the actual provider, data, retention and transfer details are documented.
3. Personalization
Optional personalization may use learning history to recommend topics. Core progress tracking needed to provide the service is separate.
4. Marketing
Marketing consent is separate from required security, verification, recovery and service messages.
5. Change your choices
Use the Privacy Center or in-app consent controls. Withdrawal applies prospectively.
6. Advertising cookies and consent
When Google AdSense is enabled, Google and approved advertising technology providers may use cookies, local storage or similar technologies to deliver, measure, limit and protect advertisements. Advertising stays disabled until the required consent-management configuration is ready. Users in regions requiring consent must receive the applicable Google-certified consent experience before personalized advertising is served.
Advertising preferences are separate from essential security, authentication and progress-storage functions. The website does not require an ad click to unlock learning content.
