Privacy Policy

CalcGuides is designed so that your calculations stay private. This policy explains what we collect, what we do not, and how we use cookies and advertising technologies.

Calculations Run in Your Browser

All calculators — mortgage, BMI, loans, tax, currency, and more — perform their math entirely on your device using JavaScript. The numbers you enter are never sent to our servers, so we never see your financial, health, or personal inputs.

Information We Collect

We do not require accounts and we do not collect personal information. We operate no forms that capture names, emails, or payment details on the calculator pages themselves.

Cookies and Google AdSense

We display advertisements through Google AdSense. Google and its advertising partners may use cookies and similar technologies to serve ads based on your prior visits to this site and other websites. These advertising cookies help deliver more relevant ads.

You can opt out of personalized advertising by visiting Google Ads Settings. You may also opt out of third-party advertising cookies through the Network Advertising Initiative opt-out page.

Analytics

We use privacy-focused analytics (Umami) to understand aggregate traffic, such as which calculators are used most. This tool avoids tracking individual visitors and does not build long-term profiles.

Your Choices

You can control cookies through your browser settings. Declining advertising cookies will not affect the calculators. You can also use the cookie banner on this site to record your preference.

Changes

We may update this policy from time to time. Changes will be posted on this page. For privacy questions, contact us at robloxguides@proton.me.
