Cookie Notice

How DeadlineDays uses browser storage, optional cookies, advertising cookies, and consent controls.

Essential cookies

The core calculator app does not require account cookies or login cookies. DeadlineDays is designed for browser-side calculation without a user account system.

Browser storage

Some calculators may use localStorage for preferences, recent calculator settings, shareable settings, or public holiday API cache data. This browser storage can be cleared from the user's browser settings.

Advertising cookies

If advertising services are enabled, Google and other third-party vendors may use cookies or similar technologies to serve and measure ads. Google advertising cookies may help serve ads based on prior visits to this site or other websites.

Personalized advertising choices

Users can manage personalized advertising settings or opt out through Google and browser-provided controls. Personalized advertising must not be served until the required consent handling and certified CMP configuration are in place in regions where consent is required.

Consent in EEA, UK, and Switzerland

When personalized advertising is served to users in the EEA, UK, or Switzerland, a Google-certified consent management platform integrated with the IAB TCF is required. Last updated: 2026-06-13.
