Privacy Policy

Last updated: August 11, 2026

What the calculator processes

The birth date you enter is processed locally in your browser to calculate calendar dates. The current version does not send, store or add that date to the page URL.

Accounts, uploads and payments

The current tool has no accounts, file uploads, payment flow or server-side user database.

Cookies and analytics

The current version does not set advertising cookies or use third-party analytics. If analytics are added after launch, this policy and any required consent controls must be updated first.

Hosting and security logs

This site is hosted on Cloudflare. Cloudflare may process standard technical information such as IP address, browser type, requested URL and request time to deliver, secure and maintain the site. See Cloudflare's privacy policy for details about its processing.

Children

The calculator can be used by families, but it is not designed to collect personal information from children. Do not enter additional identifying information anywhere on the site.

Changes

This policy will be revised if the site begins using analytics, advertising, accounts or other third-party services.
