Privacy Policy

Effective Date: October 11, 2026

This policy describes what Simple Compound Calculator ("we") does with information when you use this website. The calculator itself runs in your browser. The numbers you type are not sent to us.

1. What stays on your device

We do not ask for your name, email address, or an account. Calculator inputs, the result link in the address bar, your dark-mode choice, and your analytics choice are stored in your browser (the address bar, or local storage). We do not receive those calculator inputs.

2. Analytics, only if you accept

If you click Accept on the banner, we load Google Tag Manager (container GTM-KJ76NL4F), which loads Google Analytics. Until you accept, those scripts are not loaded. If you click Decline, we store that choice and do not load them.

When analytics is on, Google can receive:

That information can identify a browser. It is used to see how the site is used. Google processes it under its own terms. Google may store it outside the United Kingdom, including in the United States.

3. Cookies and similar storage

Essential storage is the analytics choice and, if you use it, the dark-mode choice. Those stay in local storage on your device. Google Analytics cookies are set only after you accept. You can also block cookies in your browser. Blocking them does not stop the calculator from working.

4. How to withdraw consent

You can turn analytics off at any time. Click the button below, or use Cookie settings in the footer. That stores Decline and reloads the page so Google Tag Manager is not loaded again. Cookies Google already set can be removed in your browser settings.

5. Data Security

We take reasonable measures to protect the information we collect from loss, misuse, and unauthorized access. However, please be aware that no method of internet transmission or electronic storage is 100% secure. We encourage you to use caution when sharing information online.

6. Links to Other Websites

Our website may contain links to external sites that are not operated by us. We are not responsible for the privacy practices or content of such third-party sites. Please review their privacy policies before providing any information.

7. Children’s Privacy

Our website is not intended for children under the age of 13. We do not knowingly collect or solicit personal information from children. If you believe a child has provided us with personal information, please contact us and we will promptly delete such data.

8. International Users

This website is operated from the United Kingdom. If you accept analytics, Google may process that data in other countries. Using the calculator without accepting does not send your inputs to us or to Google Analytics.

9. Your Rights and Choices

You can refuse analytics, withdraw an earlier acceptance, and delete cookies in your browser. If you want to ask about the data Google holds from this site, contact us at the email below and we will point you to Google's tools. We do not keep a copy of the calculator numbers you enter.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. We will post any updates on this page with a new effective date. Please review this policy periodically for changes.
