Privacy Policy

Overview

TradeCalc ("we", "us", or "our") operates the website tradecalc.net. This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our Service.

Information We Collect

TradeCalc is a static website with no user accounts. We do not collect personal information directly. All calculator computations happen entirely in your browser and are never sent to our servers.

We may collect anonymous usage data through third-party analytics services to understand how our site is used and improve the user experience.

After using a calculator, you may optionally rate its helpfulness. The rating is anonymous and recorded via our feedback API (your IP is one-way hashed, never stored in raw form) to help us improve calculator quality. No name or account is required, and you can use the calculators without submitting any feedback.

Advertising & Cookies

We use Google AdSense to display advertisements. Google, as a third-party vendor, uses cookies to serve ads on this site. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to this site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings (google.com/settings/ads) or www.aboutads.info.

Analytics Cookies

We use cookies and similar tracking technologies for analytics to understand how our site is used and improve the user experience. You can control cookie preferences through your browser settings. Disabling cookies may affect the functionality of certain features.

Cookie Consent Management

When you first visit TradeCalc, a cookie consent banner appears at the bottom of the screen. You may choose to accept all cookies, reject all, or manage preferences individually.

We categorize cookies into three groups: Essential (required for site functionality — always active), Analytics (Google Analytics 4, used to understand traffic and improve the site), and Advertising (Google AdSense, used to serve relevant ads).

Your consent choice is stored in your browser's local storage under the key cc_tradecalc. You can change your preferences at any time by clicking the "Cookie Settings" link at the bottom-left of any page. No cookies are set until you make a choice.

Third-Party Links

Our site may contain links to third-party websites. We are not responsible for the privacy practices of those sites. We encourage you to review their privacy policies.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date.

<strong>Do Not Sell or Share (California, CCPA/CPRA):</strong> we do not sell personal data.
