Privacy policy

At CalHub, your privacy is our priority. This Privacy Policy outlines our straightforward approach to handling your data.

1. Our Core Privacy Principle

We do not collect, store, or share your personal data. CalHub is designed to be a completely private experience. All calculations run entirely within your web browser.

2. Information We Do Not Collect

When you use our calculators, any numbers, values, or metrics you enter never leave your device. We do not have servers that record your inputs, and we do not track your individual usage behavior.

3. Cookies and Tracking

We believe in a tracking-free environment. CalHub does not set any tracking cookies, does not use fingerprinting techniques, and does not employ third-party analytics tools (like Google Analytics) to monitor your activity.

4. Third-Party Services

To provide you with the best experience, we may load strictly necessary third-party libraries (such as Chart.js via public CDNs) to render interactive elements. These providers may temporarily process your IP address to deliver the files, but they are not authorized to track you on our behalf.

5. Data Security

Because your calculations happen locally on your device and are not transmitted to us, the security of your data is inherently protected. However, we ensure that our site is served over a secure connection (HTTPS) to protect against man-in-the-middle attacks.

6. Children's Privacy

Our Service is intended for a general audience. Given our strict no-collection policy, we inherently do not knowingly collect personal information from children under the age of 13.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time to reflect changes in our practices. Any changes will be posted on this page with an updated revision date.
