Privacy Policy

At chronologicalagecalculation.com, your privacy is our priority. This Privacy Policy explains what information we do and do not collect when you use our website.

No Personal Data Collected

We do not collect, store, or process any personal data. Specifically:

  • We do not ask for your name, email address, or any identifying information to use our calculators.

  • No dates of birth, test dates, or calculation results are sent to our servers.
  • We do not store any user-entered data in databases or server logs.
