Privacy Policy

Last updated: 2026-05-01

The short version

SupplementScore stores nothing about you on our servers. The "profile" feature (your age, sex, current supplements, prescription medications) lives entirely in your browser's local storage. We never see it. If you clear your browser data or open the site on a different device, the profile is gone.

What we collect

• Local-only profile data: if you fill in the profile form, your inputs (age, sex, current supplements, medications, blood-work values, goals) are stored in your browser's localStorage. They never leave your device.
• Inaccuracy reports: when you submit a "Report inaccuracy" form, the form contents (the claim you flagged, your suggested correction, your citation, optionally your email) are sent to our forms processor (Formspree) and forwarded to our editorial inbox.
• Server logs: our hosting provider (GitHub Pages) records standard HTTP request logs (IP address, user agent, requested URL, timestamp). These are retained per GitHub's policy and we do not link them to any other identifier.

What we don't collect

• No account system. No login. No email subscription unless you explicitly sign up.
• No cookies, tracking pixels, or third-party advertising scripts.
• No analytics that follow you across the web. (If we add a privacy-friendly analytics tool like Plausible or Umami, this section will list it.)
• No payment data — the site is free and does not process payments.

Third-party services

• GitHub Pages — site hosting. GitHub privacy statement.
• Formspree — handles inaccuracy reports and contributor signup forms. Formspree privacy policy.
• Google Fonts — serves the Plus Jakarta Sans typeface. Google may log the font request. Google privacy policy.

Your rights

If you're in the EU/EEA (GDPR), the UK (UK-GDPR), or California (CCPA), you have the right to:

• Access — request what data we have about you (we can only check our inaccuracy-report inbox; we have no other store).
• Delete — ask us to delete your inaccuracy-report submission. Email the contact below.
• Export — receive your inaccuracy-report submission in a portable format.
• Opt out — clearing your browser's local storage removes the profile we never saw to begin with.

Children

SupplementScore is not directed at children under 13 and we do not knowingly collect any data from anyone under 13. If you believe a child has submitted information through our forms, contact us and we will delete it.

Changes

If this policy changes materially, the "Last updated" date at the top will change and the change will be summarised in our annual transparency report.
