Your dates stay in your browser.

DayCountLab does not require an account and does not send the dates you enter in a calculator to our servers.

Calculator inputs

Calculations run locally in your web browser. We do not intentionally collect, store, or associate calculator inputs with an individual.

Basic technical data

Like most websites, our hosting provider may process limited technical information such as IP address, browser type, requested page, timestamps, and security logs to deliver and protect the site.

Advertising and cookies

We may use Google AdSense or another advertising provider to help fund the site. If advertising is enabled, providers may use cookies or similar technologies to deliver, measure, and protect ads. Where required, you will be asked for consent before optional advertising technologies are used.

Learn more about how Google uses information from sites that use its services and manage ad personalization through Google Ad Settings.

Analytics

We may use privacy-conscious traffic measurement to understand which pages are useful and improve site performance. We do not use analytics to capture the dates entered in calculators.

Your choices

You can block or clear cookies in your browser and use the consent controls presented on the site where applicable. Blocking some technologies may change how advertising is displayed but does not prevent calculator use.

This policy may be updated when our services or legal obligations change. The review date below indicates the latest published version.
