Your dates never leave your browser.

Every calculator on SimpleDates 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.

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

We don't use cookies for advertising, and we don't sell or share any data with data brokers. If you have questions about this policy, you can reach out through the project's GitHub repository.
