Privacy Policy
Last updated: April 26, 2026
The short version
Your quiz answers never leave your device. We have no backend, no database, no user accounts. Every calculation happens in your browser using JavaScript. When you close the tab, your data is gone.
What we do NOT collect
- Your quiz answers, scores, or results
- Your name, email, or any personal information
- Health data, body measurements, or financial data you enter
- Cookies for tracking your quiz activity
This is verifiable — our entire source code is open source on GitHub. You can inspect every line.
What we DO collect (analytics only)
We use Google Analytics 4 (GA4) to understand how visitors use the site. GA4 collects:
- Pages visited and time spent
- Approximate location (country/city level, from IP address)
- Device type, browser, and operating system
- Referral source (how you found us)
GA4 does NOT have access to your quiz inputs or results. It only sees which pages you visit.
Cookies
GA4 sets the following cookies:
_ga— Distinguishes unique visitors (expires after 2 years)_ga_*— Maintains session state (expires after 2 years)
We also store your theme preference (dark/light mode) in localStorage. This is not a cookie and contains no personal data.
Third-party services
- Google Analytics 4 — Pageview analytics (Google's Privacy Policy)
- Google Fonts — Font delivery (Inter). Google may log font requests.
- Cloudflare Pages — Hosting. Cloudflare processes requests per their privacy policy.
Data sharing
We do not sell, share, or transfer any data to third parties. We have no data to share — your inputs exist only in your browser's memory.
Children's privacy
This site is not directed at children under 13. We do not knowingly collect any information from children.
Your rights (GDPR / CCPA)
Since we don't collect personal data from your quiz usage, there is nothing to access, delete, or export. For GA4 analytics, you can:
- Use an ad blocker or privacy browser to block GA4
- Install the Google Analytics Opt-out Browser Add-on
- Clear cookies to reset your GA4 identifier
Security
The site is served over HTTPS with strict security headers (CSP, HSTS, X-Frame-Options). All calculations happen client-side — there is no server to breach. Our security policy is available at /.well-known/security.txt.
Changes to this policy
We will update this page if our practices change. The "last updated" date at the top will reflect any modifications.
