Privacy Policy

1. Overview

Calculopedia runs entirely in your browser. The calculators on this site compute locally on your device — the numbers you enter are not sent to, or stored on, any server. That means your calculations stay private by design.

2. What we collect

We do not require an account, and we never ask for personal information such as your name, email address or phone number to use any calculator.

We do process anonymous, aggregated usage data to understand how the site is used and to improve it. This data does not identify you personally.

3. Analytics

We use Google Analytics to measure page views and on-site interactions, such as which calculators are used. Google Analytics uses cookies and collects a pseudonymous identifier for your device, plus technical information such as browser type and approximate location. This helps us understand which content is useful and where to focus improvements.

4. Cookies & consent

When you first visit the site, we show a consent banner. Your choice is stored locally in your browser (via localStorage) so we remember it on your next visit. You can change or clear this choice at any time from your browser's settings.

5. Advertising

Where advertising is shown, ads load only after you accept the consent prompt. Advertising partners may use cookies to show relevant ads and to measure ad performance. No ads load if you decline consent.

6. Third-party links

Pages may link to external websites (for example, related tools or informational resources). We are not responsible for the privacy practices of those sites, and we encourage you to review their policies.

7. Your choices

You can decline analytics and advertising at any time by refusing or withdrawing consent in the consent prompt, or by clearing cookies and site data in your browser. Where required by law, you also have the right to access, correct or delete any personal data we hold about you.

8. Changes to this policy

We may update this policy from time to time. Changes take effect when they are published on this page, and the "last updated" date above reflects the latest revision.

9. Contact

If you have questions about this policy, you can reach us at the contact details listed on the site.
