How Age Calculator keeps your data private
Your birth date is sensitive PII — many online age calculators log it, tie it to an IP address, or use it for ad targeting. Ours does the Date math entirely in your browser, so your birthday or the birth dates of family members you calculate never enter a database anywhere.
