What We Track
Google Analytics collects anonymized usage data, including:
Privacy-First Approach: We use Google Consent Mode v2, which defaults to cookieless tracking. This means we collect basic analytics data without using cookies unless you explicitly opt in. When you opt in, Google Analytics may use cookies to provide more detailed analytics, but you can change your preference at any time.
Your Control
You can manage your cookie preferences at any time:
- Use the "Cookie Preferences" link in the footer
- Or scroll down to the Cookie Preferences section below
- Choose to accept or deny analytics cookies
All analytics data is anonymous and aggregated. We do not collect personally identifiable information (PII) through Google Analytics. For more information about how Google uses data, please see Google's Privacy Policy.
Google AdSense
If Google AdSense is enabled on our website, Google may collect information through cookies and similar technologies in accordance with Google's Privacy Policy. We do not have access to or control over this data collection. Any data collected by Google AdSense is subject to Google's privacy practices, not ours.
Cookies
We use minimal cookies necessary for website functionality. These may include:
By default, we use cookieless tracking for analytics (see Google Analytics section above). Analytics cookies are only used if you explicitly opt in via the cookie preferences below.
Manage Cookie Preferences
Third-Party Services
We do not share any user data with third parties. The only third-party services we use are:
Google OAuth
For user authentication (handled by Google)
Google AdSense
For advertising (handled by Google, subject to their privacy policy)
Google Analytics
For website analytics (cookieless by default, opt-in for full tracking)
We do not have access to data collected by these services beyond what is necessary for their basic functionality.
Data Security
We take reasonable measures to protect the progress data we store. Your progress is associated only with an anonymous user ID, not with personally identifiable information. However, no method of transmission over the Internet or electronic storage is 100% secure.
