Privacy Policy

1 Data We Do NOT Collect

MyCalculatorHQ does not collect any personal data, identifiers, or tracking profiles. You do not need to register, verify an email, or sign in to use any of our calculators. Every calculation — age, date difference, time duration, and more — is performed entirely in your browser using JavaScript. We never transmit your input data to our servers because there is nothing to transmit. Your dates, times, and personal information stay on your device and nowhere else.

2 Local Storage & Preferences

We use the browser's localStorage feature for one purpose only: remembering your dark/light theme preference. That is it. No scores, no usage history, no behavioral data is stored or transmitted.

• Your theme preference stays on your device only.
• We have no access to your localStorage data.
• You can clear all site data at any time through your browser settings.

3 Cookies & Third-Party Services

MyCalculatorHQ does not set tracking cookies. We do not use Google Analytics, Facebook Pixel, or any third-party tracking scripts. The only external request our pages make is to Google Fonts for the Inter typeface. If we ever introduce advertising or analytics partners in the future to keep this site free, they will comply with standard privacy guidelines, and we will update this policy accordingly.

4 Contact Information

If you have any questions or concerns about this privacy policy, you can reach us through our Contact Us page. We are happy to clarify exactly how your data is (or is not) handled.
