Privacy Policy
Last updated: June 2025
What we collect
StainMatrix does not require any account creation or personal information to use. We collect anonymous usage analytics (page views, device type, country) via Vercel Analytics to understand how the site is used and improve it over time. This data is aggregated and not linked to any individual.
Google AdSense
We serve advertisements via Google AdSense. Google may use cookies and similar technologies to show you ads based on your interests. You can opt out of personalised ads through Google's Ad Settings.
Amazon Associates
Some pages contain Amazon Associates affiliate links. If you click and purchase, we may earn a small commission at no cost to you. We only link to products that are relevant to the stain treatment described.
Cookies
StainMatrix itself does not set cookies. Third-party services (Google AdSense, Vercel Analytics) may set their own cookies per their privacy policies.
Your rights
Under GDPR and CCPA you have the right to know what data is held about you and to request its deletion. Because StainMatrix collects no personally identifiable information, there is no individual data to delete. For Google AdSense data, contact Google directly.
