Information We Collect

MatrixCalc does not collect personal information. All matrix calculations run entirely in your browser — your matrix entries, equation coefficients, and computed results never leave your device and are never transmitted to our servers. You can use every tool on MatrixCalc completely anonymously.

Analytics

MatrixCalc uses Google Analytics 4 to collect anonymous usage data such as page views, session duration, and which tools are used most frequently. GA4 is configured with IP anonymization, so your IP address is never stored in identifiable form. This aggregate data helps us improve the site and prioritize new calculators. No personally identifiable information is collected. You can opt out via the Google Analytics opt-out browser add-on.

Cookies

MatrixCalc does not set first-party cookies. Google Analytics sets cookies (such as _ga and _ga_*) to distinguish users and sessions. Google AdSense may set cookies to deliver and measure advertisements. You can opt out or block these cookies via your browser settings. Doing so will not affect the functionality of our matrix calculators.

Advertising

We use Google AdSense to display ads that help keep MatrixCalc free. Google may use cookies to show relevant ads based on your visits to this and other sites. You can manage ad personalization at Google Ad Settings.

Third-Party Services

Our only third-party service integrations are Google Analytics and Google AdSense, both governed by Google's Privacy Policy. We do not sell or share user data with any other parties.

Children's Privacy (COPPA)

MatrixCalc is not directed at children under 13. We do not knowingly collect personal information from children. Our site requires no registration or personal data to use any calculator. If a parent or guardian believes their child has submitted personal information via our contact form, please contact us to have it removed.

Data Retention

Because MatrixCalc collects no personal data, there is nothing to retain. Anonymized analytics data is retained per Google Analytics' standard schedule. Contact form submissions are kept only as long as needed to respond to the inquiry.

Changes to This Policy

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