Privacy Policy

Last updated: May 2026

At Chronological Age Calculator, we take your privacy extremely seriously. Because our tool is frequently used in clinical and educational settings, we have built it with privacy at its core.

1. Data Collection and Storage

Our age calculator performs all mathematical operations entirely within your internet browser (client-side). We do not collect, transmit, or store any of the names, dates of birth, or test dates you input into the calculator. Once you close your browser tab, all session data is wiped.

2. File Exports

When you use our tool to generate a PDF report or export a CSV file of roster ages, that file generation happens directly on your device. No data is sent to a remote server for processing.

3. Cookies and Local Storage

We use minimal local storage purely to remember your user interface preferences, such as whether you prefer Light Mode or Dark Mode. We do not use intrusive tracking cookies or sell your browsing data to third parties.

4. Contact Us

If you have any questions or concerns regarding this Privacy Policy, please feel free to contact us.
