Your dates never leave your browser.

Every calculator on Simple Age runs entirely client-side. When you enter a birth date or any other date, it is used only to compute a result in your browser's memory. Nothing you type into a calculator form is sent to our servers, stored in a database, or shared with any third party.

Simple Age uses Google Analytics to understand aggregate traffic patterns, such as which pages are visited and how many people use each calculator. This is never linked to the dates or personal information you enter into a calculator.

Google AdSense may use cookies or device identifiers to show and measure ads. Where required, we request your consent through Google's Funding Choices message. Use the Privacy choices link in the footer to review or change your choice. We don't sell your calculator inputs or share them with data brokers.
