Data we collect
SellerTools Online does not collect personal data. All calculations run entirely in your browser using JavaScript. We do not send any numbers you enter to our servers.
Analytics
We use analytics tools, including Google Analytics and Microsoft Clarity, to understand how visitors use the site, improve page design, and identify technical issues. These tools may collect usage data such as pages visited, clicks, scroll behavior, browser type, device type, approximate location, referrer, and session interactions. Microsoft Clarity may provide heatmaps and session replay features. We do not use these tools to collect the calculator numbers you enter, and we do not sell your personal data.
Cookies
Analytics providers may set cookies or similar technologies to measure site usage and distinguish visits. This site does not use advertising cookies for our own ad targeting.
Affiliate links
Some tool pages contain affiliate links to Amazon.com. Clicking these links may set an Amazon affiliate cookie. See our Affiliate Disclosure for details.
