Privacy Policy
Last updated: April 19, 2026
1. Information we collect
- Quiz answers (gender, age, goals, body composition, budget, etc.)
- Email address and archetype code if you subscribe to the newsletter
- Name, email, message if you use the contact form
- Quiz answers cached in your browser's local storage (on your device only)
- Aggregate completion metadata (archetype code, goal, budget, frequency) — anonymous, no PII
- Affiliate link click data (which supplement and vendor you clicked) — no IP or user-agent stored
- Anonymous traffic data via analytics (e.g. Vercel Analytics)
2. How we use information
- Generate and display your supplement stack
- Deliver the newsletter (subscribers only)
- Respond to contact-form inquiries
- Statistical analysis to improve the service (non-identifying)
3. Third-party sharing
We do not share personal information with third parties without consent, except where required by law.
4. Cookies and local storage
Quiz answers stay in your browser's sessionStorage and are never sent to our servers. The only data persisted server-side is newsletter signups and contact-form submissions.
5. Affiliate disclosure
Product links on this site include affiliate programs (iHerb Rewards, Amazon Associates, A8.net, MyProtein, Rakuten). We may earn a commission when you purchase through them, but this never affects the price you pay. Recommendations are based on scientific evidence and your quiz answers alone — commission rates have zero influence on ranking.
6. Data retention and deletion
Newsletter signups are retained until unsubscribe. Contact-form submissions are retained for two years after resolution. You can request deletion at any time and we will respond within a reasonable timeframe.
7. Contact
For questions about how we handle your data, please use our contact form.
8. Changes to this policy
We may update this policy without prior notice. Updates take effect upon publication on this page.
