Privacy Policy

Last updated: March 16, 2026

Website (verifiedsupplementdata.com)

Data We Collect

We collect no personal data. We do not use cookies for tracking, do not require accounts, and do not collect email addresses, names, or any personally identifiable information.

Analytics

We use Cloudflare Web Analytics, which is privacy-first and does not use cookies or collect personal data. It provides aggregate page view and visitor counts only.

Affiliate Links

Product links on this site use Amazon Associates affiliate tags. When you click a product link and make a purchase on Amazon, we earn a small commission at no additional cost to you. Amazon's privacy policy governs data collection on amazon.com. We do not receive any personal information about your Amazon purchases.

APIs

Our public APIs (recommendation API, form classifier, product feeds) do not require authentication and do not log personally identifiable information. API request logs contain only timestamps and requested URLs for performance monitoring.

Chrome Extension (Supplement Checker)

What the Extension Does

The Supplement Checker extension analyzes supplement product pages on Amazon.com. It reads the product title, description, and ingredient information on your device only to identify the supplement form and provide evidence-based analysis.

Data Collection

The extension collects no data. Specifically:

  • No browsing history is collected or transmitted
  • No personal information is collected
  • No data is sent to our servers or any third party
  • All analysis happens locally in your browser
  • The evidence database is bundled with the extension, not fetched remotely

Permissions

The extension requests permission to run on Amazon.com product pages only. It does not access any other websites. It uses storage.sync to save your medication list (if you choose to enter one) — this data stays in your Chrome profile and is never sent to us.

Affiliate Disclosure

Links to verifiedsupplementdata.com comparison pages from the extension may contain affiliate links. This is clearly disclosed in the extension interface. The extension does not modify Amazon product pages, inject affiliate links into Amazon, or alter any existing links.
