Privacy Policy
Read the SellerCalc privacy policy covering calculator use, technical information, links, analytics and advertising.
Effective date: August 26, 2026
Overview
SellerCalc is a free website providing marketplace seller calculators and educational resources. We aim to collect as little personal information as reasonably necessary to operate the site.
Calculator information
Calculator fields are intended for business estimates. Do not enter passwords, payment card information, marketplace login credentials or other sensitive information. Where calculations are performed in the browser, the values entered are used to produce the displayed estimate.
Technical information
Like most websites, the hosting platform may process technical information such as IP address, browser type, device information and request data for security, reliability and performance. SellerCalc uses third-party advertising services, including Adsterra, to display ads. These providers may process technical information such as IP address, browser/device information, approximate location and advertising identifiers or cookies as permitted by their systems and applicable law. Their data practices are governed by their own privacy policies and controls.
Third-party links and services
SellerCalc may link to marketplaces, social networks and other third-party websites. Their privacy practices are controlled by those providers, not SellerCalc.
Changes
This policy may be updated when the website, analytics, advertising or data practices change. The effective date above will be updated when material changes are made.
