Privacy Policy

Last updated September 5, 2026

Short version: this site doesn't want your data. There are no accounts, no email forms, no ad networks, and no tracking pixels.

What happens to the numbers you type

Every tool on Trading Ranges runs inside your browser. The prices, sizes, and account figures you enter are used on your screen and nowhere else. They are never sent to a server. Close the tab and they're gone.

What gets saved on your device

A few tools remember things between visits so you don't have to start over: the trainer keeps your score and streak, and some tools keep your last settings. That information sits in your browser's local storage, on your device, under your control. Clearing your browser data wipes it. We can't see it.

What we do receive

When you load a page, the company that hosts these files receives the usual web request: your IP address, browser type, and the page you asked for. That's how the internet delivers a page. We don't use those logs to identify you or build a profile.

Pages load two typefaces (Inter and JetBrains Mono) from Google Fonts. That means your browser makes a request to Google's servers when a page opens. Google's own privacy policy covers what Google does with that request.

Cookies

This site sets none.

Other sites

If a page links out to another website, that site has its own rules. Read theirs before you trust them with anything.

Kids

This site is for adults who trade. It isn't aimed at anyone under 18 and we don't knowingly collect anything from them.

Changes

If this policy changes, the date at the top changes with it. The version on this page is the one that applies.
