1. Overview

AI-200 Prep ("we", "us", "our") operates the website ai200prep.com. This Privacy Policy explains how we handle information when you use our site. We are committed to being transparent about our practices and protecting your privacy.

This site is a free, static educational resource. We do not require you to create an account, and we do not sell or share personal data with third parties for commercial purposes.

2. Information We Collect

2.1 Automatically Collected Data

When you visit our site, our hosting provider (Cloudflare Pages) may automatically collect standard web server log data, which can include:

IP address (anonymised)
Browser type and version
Operating system
Pages visited and time spent
Referring URL
Date and time of visit

This data is processed by Cloudflare under their own Privacy Policy.

2.2 Analytics

We may use privacy-respecting analytics tools to understand how our content is used and improve the site. Any analytics we use will not track you across other websites and will not use persistent cookies for advertising.

2.3 Local Storage

We use browser localStorage to save your theme preference (dark/light mode). This data stays on your device and is never transmitted to our servers.

3. Cookies

This site does not use advertising cookies, tracking cookies, or third-party marketing cookies. We only use essential browser storage (localStorage) for your theme preference. No cookie consent banner is required as we do not serve non-essential cookies.

4. How We Use Your Information

Any data collected is used solely to:

Operate and maintain the website
Monitor site performance and security (via Cloudflare)
Understand which content is most useful to visitors
Diagnose technical issues

We do not use your data for advertising, profiling, or sell it to any third party.

5. Third-Party Services

Our site is hosted on Cloudflare Pages. Cloudflare provides CDN, DDoS protection, and analytics services. Please review Cloudflare's Privacy Policy to understand their data practices.

We may embed content from YouTube (for video walkthroughs). YouTube videos are loaded from YouTube's servers and are subject to Google's Privacy Policy. We use youtube-nocookie.com embeds where possible to minimise tracking.

6. Data Retention

We do not store personal data on our own servers. Cloudflare may retain access logs for a limited period in accordance with their data retention policies.

7. Your Rights

Depending on your location, you may have rights under applicable privacy laws (e.g., GDPR, UK GDPR, CCPA) including:

Right to access the data held about you
Right to erasure ("right to be forgotten")
Right to object to processing
Right to data portability

Since we do not collect or store personal data directly, most of these rights apply to our third-party processors (Cloudflare). Contact us if you have any concerns.

8. Children's Privacy

This site is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information to us, please contact us and we will take steps to remove it.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by the "Last updated" date at the top of this page. Continued use of the site after changes constitutes acceptance of the updated policy.
