Calculator data
SellerMath Tools calculators run in your browser. The numbers you type into the calculators are used to update the result on the page and are not submitted to SellerMath Tools by the calculator itself.
Market Atlas data and browser storage
Market Atlas stores your country shortlist and cached economic and exchange-rate data in this browser's local storage using keys beginning with atlas-. Clear this site's browser data to remove them. Pricing inputs are calculated locally and are not submitted to SellerMath by the tool.
Market Atlas includes a bundled dataset and requests updates from api.worldbank.org and api.frankfurter.dev. These providers receive normal connection information such as your IP address. Economic data is checked when older than 30 days and exchange rates when older than 7 days, on opening and hourly while the page remains open. There is no background server scheduler; failed updates retain the previous data. Google Fonts supplies the font through fonts.googleapis.com and fonts.gstatic.com, which also receive connection information.
