What is a cookie?
A cookie is a small text file a website asks your browser to keep. Browsers also offer related storage mechanisms — localStorage, sessionStorage, and IndexedDB — that work in similar ways. CountDay.org uses both true cookies (set by Google's services) and localStorage (used by the site itself to remember your countdowns). This page treats them together because the privacy implications are the same.

Strictly necessary
These keep the site usable. The countdowns you create are stored in your browser's localStorage under the keys used by the site (for example countdowns). This is what makes "no signup" possible — your countdowns travel with the browser, not with our servers. If you block this storage, the create-countdown feature will not be able to remember anything between page loads.
Analytics
Google Analytics 4 (measurement ID G-MK5PVK6WL0) sets cookies in the _ga family — typically _ga and _ga_<container-id>. These let Google recognise repeat visits to the site and report aggregate traffic. The data is used to understand which pages are useful and which are slow. The _ga cookie is normally retained for up to two years; _ga_<container-id> is similar. You can disable it in your browser, with an extension, or via the controls below.
Advertising
Google AdSense and its partners may set cookies — including those in the __gads, __gpi, IDE, and NID families — to deliver ads, measure ad performance, and limit how often you see the same ad. If you have not opted out of personalised advertising, these cookies may also be used to show ads relevant to your interests based on your activity on this and other sites in Google's network.
Functional
Loading Google Fonts may cause your browser to receive a small font cache identifier from Google. We do not set our own functional cookies beyond what localStorage stores for countdowns.
How to opt out or limit cookies
Personalised ads
Google's Ad Settings let you turn off personalised ads across Google services, including AdSense. The industry-wide opt-outs at YourOnlineChoices.com (Europe) and optout.aboutads.info (US) cover many third-party advertising vendors that participate in the AdSense ecosystem.
Analytics
Google publishes a Google Analytics opt-out browser add-on that prevents Analytics from sending data when you visit any site, including this one.
Browser controls
Every modern browser lets you view, block, and delete cookies. Look in your browser's settings under "Privacy," "Site data," or "Cookies." Blocking all cookies will break parts of many websites; blocking third-party cookies is a moderate compromise that disables most ad and cross-site analytics while leaving site features mostly intact.
Removing your countdowns
To clear the countdowns you created on this site, open your browser's site-data settings for countday.org and remove storage. You can also delete countdowns one at a time on the home page.
Do Not Track
The Do Not Track browser signal does not have a single agreed-upon meaning. We do not currently change site behaviour based on the DNT header; the controls described above are the most reliable way to limit tracking on this site.
Changes to this policy
If we add or remove a service that uses cookies, we revise this page and update the "Last reviewed" date.
