Privacy Policy

Last updated: March 2026

1. Overview & Data Philosophy

At DrinkingWaterFilter.org, we prioritize visitor privacy above all. Our interactive diagnostic tools (Filter Matcher, Annual Savings Calculator) execute client-side entirely in your web browser. We do not store, sell, or transmit personal medical or water test answers to external servers.

2. Cookies & Analytics

We use privacy-friendly minimal telemetry to analyze traffic volume and ensure high server availability. We do not deploy invasive cross-site tracking cookies.

3. Third-Party Links & Affiliate Partnerships

When you click on an external link to purchase a water filter on Amazon, you will be redirected to Amazon’s respective regional storefront (Amazon.com or Amazon.es). Those external websites maintain their own independent privacy policies and tracking terms.

4. Contact Information

For privacy inquiries or data rights requests under GDPR or CCPA, email privacy@drinkingwaterfilter.org.
