Our Commitment to Minimizing Third-Party Dependencies

We regularly review our third-party service integrations to ensure they align with our privacy-first philosophy. Our goal is to provide a rich educational experience while minimizing data collection and external tracking. We prioritize services that offer strong privacy protections and transparent data practices.

Third-Party Policies and Data Sharing

We may share your information with third-party service providers who assist us in operating our website, conducting our business, or serving our users. These third parties have access to your personal information only to perform specific tasks on our behalf and are obligated not to disclose or use it for any other purpose.

Analytics Services

We previously used Google Analytics to analyze website traffic and user behavior, but have since removed all analytics services.

Advertising Networks

We use Google AdSense to display advertisements on our website. These services use cookies and web beacons to serve ads based on your prior visits to our site or other websites. You can control ad personalization through your Google Ad Settings or opt out through industry opt-out tools.

Data Processing Agreements

All companies we work with must keep your information safe and use it only for what we tell them to do.

Data Storage and Security
