1. Introduction
MathGyro ("we", "us", "our") operates the website mathgyro.com. This Privacy Policy explains what information we collect, how we use it, and your rights under the General Data Protection Regulation (GDPR) and other applicable privacy laws. By using our website you agree to the practices described below.
2. Data Controller
The data controller for mathgyro.com is MathGyro. You can reach us at contact@mathgyro.com for any privacy-related inquiries.
3. Information We Collect
MathGyro is a static website and does not require registration. We do not collect names, email addresses, or payment information through the site. The only data we may process includes: anonymous usage analytics via Google Analytics 4, aggregate cookie-free visit and performance metrics via Cloudflare Web Analytics, device type and browser information sent automatically by your browser, and locally stored preferences (theme, calculation history) which remain on your device and are never transmitted to our servers.
4. Cookies and Local Storage
Google Analytics 4 sets first-party cookies to distinguish users and sessions. You can block these via your browser settings or a cookie-management extension. Cloudflare Web Analytics does not use cookies. We use browser localStorage to save your theme preference and recent calculations. This data stays on your device and is not sent to any server.
We also display advertising served by Google AdSense. Google and its certified third-party vendors use cookies (including the DoubleClick cookie) to serve ads based on your prior visits to this and other websites. You can opt out of personalised advertising at any time through Google Ads Settings (google.com/settings/ads), and you can opt out of third-party vendors' use of cookies for personalised advertising at aboutads.info. You can also review how Google uses data from sites that use its services at policies.google.com/technologies/partner-sites.
5. How We Use Information
We use anonymous analytics data solely to understand which tools are most popular, identify technical errors, and improve the user experience. We never sell or rent your personal data. The analytics and advertising services we use may set their own cookies, as described in the Cookies and Third-Party Services sections.
