Short version: Unit Circle Quiz does not require an account or ask for your name, email, or school. Practice mistakes and progress are stored locally in your browser. Production pages use Google Analytics to understand general site usage.
1. What this policy covers
This Privacy Policy explains how UnitCircleQuiz.com ("Unit Circle Quiz," "we," or "the site") handles information when you visit the site or use its quiz, fill-in circle, review, speed test, reference, and worksheet features. The site is a free educational tool for practicing unit-circle trigonometry.
2. Information you provide
The site currently has no account system, sign-in flow, checkout, or contact form. You can use the practice tools without submitting your name, email address, school, or other personal details to us.
If you contact the site operator by email, the operator will receive the information you choose to include in that message and will use it to respond to your request. Do not include sensitive information in a support message.
3. Information stored in your browser
Some practice features use browser storage so the tool can remember your learning state on the same device. This may include missed questions, spaced-review dates, and practice counts by skill, quadrant, angle, or level. This information is stored in your browser and is not intentionally uploaded to our server.
- Clearing the site’s browser storage can remove these records.
- Private browsing, storage restrictions, or browser settings may prevent records from being retained.
- Another person using the same browser profile may be able to see or change local practice state.
4. Shared practice links
The Share settings feature creates a link containing practice settings such as the selected mode, level, topic, question count, and answer style. It does not intentionally include your answers, mistakes, or practice history. Anyone you give the link to can see those settings, so share links only with people you trust.
These settings are placed in the URL fragment after the # symbol. Browsers normally do not send that fragment as part of an HTTP request, but a copied link can still reveal its settings to the person who receives it.
5. Analytics and cookies
On production pages, the site uses Google Analytics 4 to understand broad usage and improve the experience. Google Analytics may collect technical and usage information such as browser type, device information, approximate location, page views, and interaction timing. The site does not intentionally send quiz answers, local mistake records, or typed practice responses to Google Analytics.
Google Analytics may use cookies or similar technologies. You can limit cookies through your browser settings, use content-blocking tools, or review Google’s available controls. Blocking analytics does not prevent the practice tools from working.
6. How information is used
Information described in this policy is used to provide the site, keep local practice features working, understand aggregate site performance, detect technical problems, and respond to messages sent to the site operator. We do not sell personal information and do not use the quiz to make decisions about a student.
7. Third-party services and links
The site relies on Google Analytics for measurement. The site also links to its own pages and may link to third-party resources in the future. When you follow an external link, that destination’s privacy policy applies. Review third-party terms before sharing information with another service.
8. Children and educational use
Unit Circle Quiz is intended for general educational use. Because the site does not require an account or knowingly request personal information from children, the best way to use it with younger students is under the supervision of a parent, teacher, or school. Please contact the site operator if you believe personal information was submitted accidentally.
9. Your choices and requests
You can stop analytics collection by blocking analytics technologies in your browser. You can remove locally stored practice records by clearing this site’s storage in your browser. Because the site does not maintain a user account or server-side practice profile, there is generally no online account to close or practice history for us to export.
For privacy questions or requests, email [email protected].
10. Changes to this policy
We may update this policy when the site’s features, analytics, or legal obligations change. The “Last updated” date at the top will show when the current version was published. Continued use of the site after an update means you have had an opportunity to review the revised policy.
