Privacy Policy
Last updated: July 4, 2026
SellerSums is built to work without collecting personal data. There are no accounts, no sign-ups and no forms asking for your details.
Calculator inputs
Everything you type into a calculator is processed in your browser. Inputs are saved to your browser's local storage so they're still there when you come back, and they are encoded into the URL only when you click "Share". They are never sent to our servers.
Analytics
We may use Google Analytics 4 with IP anonymization to understand aggregate usage (pages visited, calculator interactions). This data is not used to identify individuals. If a cookie consent banner is shown in your region, analytics and advertising cookies are only set after you consent.
Advertising and affiliate links
Pages may contain advertising and affiliate links (see our affiliate disclosure). Ad networks may use cookies subject to your consent choices. We do not sell personal data.
Your rights
Depending on your region (including under UK/EU GDPR), you may have rights to access, correct or delete personal data. Since we hold none, exercising these rights typically means clearing your browser's local storage and cookies. Questions: contact us via the blog at blog.sellersums.com.
