Who We Are

The Claude Certification Guide (claudecertificationguide.com) is an independent, free educational resource for developers preparing for the Claude Certified Architect (Foundations) exam. It is not affiliated with Anthropic.

What Data We Collect

We collect minimal data to understand how the site is used and to improve the learning experience:

• Analytics data — We use Google Analytics (GA4) and Vercel Analytics to collect anonymous usage data including page views, session duration, device type, browser, and approximate geographic location. No personally identifiable information is collected by these tools.
• Local storage data — Your study progress, practice exam history, and theme preferences are stored in your browser's local storage. This data never leaves your device and is not transmitted to any server.
• Feedback submissions — If you use the feedback button, any text you submit is collected to improve the site. Do not include personal information in feedback messages.
• Waitlist email addresses — If you join the launch waitlist for an upcoming certification track, we collect the email address you submit and which track you chose. That is the only personal data the form collects, and joining is optional.

Cookies and Tracking

Google Analytics uses cookies to distinguish unique users and sessions. These are first-party cookies set by Google's analytics script. Vercel Analytics does not use cookies. We do not use any advertising cookies or tracking pixels.

How We Use Your Data

• To understand which content is most useful and where users spend time
• To identify technical issues (broken pages, slow load times)
• To improve lessons, practice questions, and study materials
• To send waitlist subscribers a single launch email when the certification track they signed up for goes live

We do not sell, share, or transfer your data to third parties for marketing or advertising purposes.

Third-Party Services

• Google Analytics (GA4) — Privacy policy: policies.google.com/privacy
• Vercel Analytics — Privacy-friendly, cookieless analytics. Privacy policy: vercel.com/legal/privacy-policy
• Vercel (hosting) — The site is hosted on Vercel's infrastructure. Vercel processes server logs containing IP addresses as part of standard web hosting.
• Brevo (email) — Waitlist email addresses are stored and sent through Brevo, the email platform acting as our data processor for launch notifications. Brevo receives only the address you submit and the track you chose, and stores that data within the European Union. Privacy policy: brevo.com/legal/privacypolicy

Your Rights

The waitlist is the only place we deliberately collect personal data. Every email we send includes an unsubscribe link, which stops future sends. To have your address deleted entirely, use the feedback button on any page and include the address you signed up with — the one exception to the rule about keeping personal information out of feedback.

Beyond that, we do not collect personally identifiable information, so there is typically no personal data to access, correct, or delete. If you want to opt out of Google Analytics tracking, you can install the Google Analytics Opt-out Browser Add-on. To clear local study progress data, clear your browser's local storage for this site.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated date.
