Last updated: November 3, 2026
This policy describes how Seller Tools Lab may collect and use information when you visit the website.
Calculator inputs
The calculator values you enter are processed in your browser. The current static version of the site does not send those inputs to a server or require an account.
Analytics
The site can be configured to use a privacy-oriented page analytics service. If analytics is enabled, the service may receive technical information such as the page requested, the referring page, approximate location derived from the request, browser type, and device type. The site should not send calculator inputs to analytics.
Advertising and cookies
If third-party display advertising is enabled, the advertising provider may use cookies or similar technologies to measure ads and personalize content where permitted. For visitors in regions that require consent, a compliant consent management platform should be used before advertising cookies are set.
Affiliate links
Some outbound links may be affiliate links. If a visitor buys through an affiliate link, the site may receive a commission at no additional cost to the visitor. See the affiliate disclosure page for more information.
Third-party services
The site may use hosting, analytics, advertising, and affiliate services. Their own privacy policies govern how they process information. Before launch, list the actual providers and link to their policies.
Your choices
You can use the calculators without providing an account. You can block cookies through your browser, use a content blocker, and contact the site to ask about privacy choices. Where local law provides access, correction, deletion, or objection rights, use the contact page to make a request.

Privacy questions can be sent to the site contact address.
