Data Annotation Cookie Policy

Effective: 25 November 2025

This Cookie Policy explains how Data Annotation ("we", "us", "our") uses cookies on https://www.dataannotation.tech/ (the "Website") and how we use pixels.

This Cookie Policy should be read alongside our Privacy Notice.

What Are Cookies and Pixel Tags?

"Cookies" are small files, containing letters and numbers, that are downloaded and stored on your browsing device, such as your computer, phone or tablet, when you visit a website. Cookies can be placed, read, and/or written to by our Website, or other websites or services that recognize a particular cookie, which allows the website to "remember" or "recognize" a particular browser or device and, in some cases, store information about that browser or device. Cookies help websites know whether the browsing device has visited the website before and can remember your preferences and settings for online services.

Certain types of cookies or cookie-like functionality may be placed or activated through browser add-ons, including, but not limited to, Adobe Flash. While these cookies are stored differently, their functionality and purpose is generally similar to other cookies.

Cookies are often used in conjunction with "pixel tags" (also known as "web beacons" or "clear gifs"). Pixel tags are small images that we, our analytics providers, advertisers, and other third parties can use to interact with cookies and other tracking technologies. For example, we use pixel tags to evaluate the effectiveness of our advertising and marketing campaigns and for desktop web push notifications.

For more information about cookies, please see www.allaboutcookies.org.

How Long Are Cookies Stored On My System?

A cookie may be classified as either a "first" or "third" party cookie, depending on whether the cookie is placed directly by the website that the user is visiting. A first-party cookie is set directly by the website you are visiting, whereas a third-party cookie is set by a third-party entity via the website you are visiting. The duration for which a cookie remains on your device depends on whether it is a "session" cookie or a "persistent" cookie.

"Session Cookies" are temporary files that are created when you open your browser and remain active only for as long as your browsing session lasts. These cookies are automatically removed from your device once you close your browser or log off. Websites use session cookies to identify and connect your actions during a single browsing session and to manage your user session.

"Persistent Cookies" remain on your device for a specified period of time. Unlike session cookies, persistent cookies are not deleted when you close your browser. Instead, they remain until they reach their set expiry date, or you manually remove them. Persistent cookies are commonly used to monitor user behaviour as you navigate a website, and the information collected can be used to build a profile of your browsing habits in order to recommend products, services, or content tailored to your interests.

Your choices may affect whether we use session or persistent cookies for a particular application.

Third-Party Functionality

We do not have access to or control over cookies or other features that advertisers and third party sites may use, and the information practices of those advertisers and third party websites are not covered by our Privacy Notice or this Cookie Policy.

For example, we provide social media buttons on the Website that allow users to visit, share, or bookmark web pages through third-party social media platforms, including Facebook (Meta), X (formerly Twitter), TikTok and Instagram. In addition, we may embed content or utilise features from other third-party services, such as YouTube videos or Google services, to enhance your experience on the Website. These third-party platforms and services may collect information about you, track your activity, or place their own cookies or similar technologies on your device when you interact with their content or features on our Website.

We do not control how those platforms collect information about you, nor whether or how they may track you or may activate their own cookies on your computer. This includes, for example, the use of LinkedIn cookies in connection with our advertising or analytics activities, even though we do not provide a LinkedIn social media button on the Website. For more information about how these third parties collect and use information about your activities, please review their applicable Terms of Use and Privacy Policies.
