Calculatormatics.com ("we", "us", "our") operates the website at https://calculatormatics.com. This page informs you of our policies regarding the collection, use, and disclosure of personal information when you use our website.
Information We Collect
Calculator Inputs
All calculations are performed entirely in your browser (client-side JavaScript). We do not collect, store, or transmit any numbers you enter into our calculators. Your financial data, health measurements, and other inputs never leave your device.
Analytics Data
We use Cloudflare Web Analytics, a privacy-focused analytics service that does not use cookies, does not collect personal data, and does not track individual users across sites. It collects only aggregate page view and performance data. No consent is required for this service under GDPR, ePrivacy, or CCPA regulations.
Contact Form
If you contact us through the Contact page, we collect the information you provide: your name, email address, and message content. We use this information solely to respond to your inquiry. We do not add you to any mailing list or share your contact information with third parties.
Cookies

We display advertisements through third-party ad networks (such as Google AdSense). These services may use cookies to serve personalized ads based on your browsing history. Ad cookies are only loaded after you accept cookies through our consent banner. If you decline cookies, no ad tracking cookies are set.
