2. Calculator Data — What We Do NOT Collect

Our calculators (Age Calculator, Days Alive Counter, Birthday Countdown, Retirement Calculator, Life Expectancy, and Work Anniversary) operate entirely within your web browser. This means:

  • Your date of birth is never transmitted to our servers.
  • Your name or any other input you provide to the tools is never stored.
  • All calculations are performed locally on your device using JavaScript.
  • Closing the browser tab permanently removes all inputs — nothing is retained.
