Privacy Policy

Last updated: October 2026.

TradeCalc calculators run entirely in your browser. We do not collect, store, or transmit anything you type into a calculator — your measurements never leave your device. There are no accounts and no signup, so we hold no names, email addresses, or passwords.

Cookies and analytics

We use Google Analytics to understand aggregate site usage (pages visited, approximate location, device type). Google Analytics uses cookies — such as _ga — to distinguish visits. We do not combine this with any personal data because we collect none, and we do not use analytics data to identify individual visitors.

Like every website, our hosting provider necessarily processes standard web-server log data (such as IP address, requested page, and time) in order to deliver the pages. We do not combine this with anything else and do not use it to identify you.

Your consent choice: when you first visit, a cookie banner asks for your consent. Choosing Accept enables these analytics cookies; choosing Decline keeps them off entirely. Your choice is remembered on your device, and clearing this site's stored data will ask you again.

Your choices: you can block or delete cookies in your browser settings, and Google offers an opt-out browser add-on for Google Analytics. Blocking cookies does not affect the calculators — they work fully without them.

Data retention

Because calculator inputs never leave your browser, there is nothing to retain from your use of the tools themselves. Aggregate analytics data is held by Google under its own retention settings, and advertising cookie data is governed by Google's policies linked above. We keep no user database, no logs of calculator inputs, and no profiles — there is simply nothing of yours on our servers to retain or delete.

Advertising

We use Google AdSense to serve ads, which keeps the calculators free. Google may use cookies (including the DoubleClick cookie) to serve ads based on your visits to this and other sites. You can opt out of personalized advertising at Google's Ads Settings. See Google's advertising policies for details.

Children's privacy

TradeCalc is a general-audience site not directed at children under 13, and we do not knowingly collect personal information from children. Because the calculators run entirely in your browser, there is nothing for a child (or anyone) to submit to us in the first place. If you believe a child has emailed us personal information, contact us at the address below and we will delete it.

Changes to this policy

If this policy changes, the "Last updated" date above will change with it, and material changes will be described here. Continued use of the site after changes means you accept the updated policy.
