Privacy.

What we collect

• Anonymous page views via Google Analytics 4
• Anonymized IP address (anonymize_ip: true — the last octet is dropped before storage)
• Browser type, OS, and screen size (collected by GA4 automatically)
• Interaction events: reveal_answer, bookmark_toggle, cta_click — each containing only a question ID, section, or CTA placement label

What we don't collect

• Your name, email, or phone number
• Your study progress — that's stored in your browser only (localStorage), never on our servers
• Your bookmarks — same: local to your device
• Your precise location (IP is anonymized)

Do Not Sell My Personal Information

Cookies

Google Analytics 4 uses cookies (_ga, _gid) to recognize return visits anonymously. Once you disable analytics above, no new analytics cookies are set. Existing cookies can be removed via your browser settings.
