Privacy Policy
Short version: we don't collect your data.
Last updated: November 11, 2026
What You Enter
Every number you type into a calculator stays in your browser. Calculations run locally in JavaScript; nothing is sent to a server, saved in a database, or shared with anyone.
To make results shareable, the calculator writes your inputs into the page address (for example ?amount=100). That address is only stored where you choose to put it, such as your browser history or a link you share.
Cookies, Analytics and Ads
Ecom Fee Calculator sets no cookies, runs no analytics or advertising scripts, and loads no third-party trackers or fonts.
Hosting
The site is served by a content delivery network. Like any web server, it may process technical data needed to deliver pages and protect against abuse, such as your IP address, browser type and the page requested. We do not use this data to identify or profile visitors.
Links to Other Sites
Calculator pages link to official platform pages so you can check our sources. Those sites have their own privacy policies.
Changes
If this policy changes, the date at the top of this page will change too.
