This Cookie Policy explains how Chainguard Inc. ("Company", "we", "us", and "our") uses cookies and similar technologies to recognize you when you visit our websites at https://chainguard.dev, https://edu.chainguard.dev, https://images.chainguard.dev, and https://courses.chainguard.dev ("Websites"). It explains what these technologies are and why we use them, as well as your rights to control our use of them.

In some cases, we may use cookies to collect personal information, or that becomes personal information if we combine it with other information. If we do, any personal information collected will be used in accordance with our Privacy Policy.

1. What are cookies?

Cookies are small data files that uniquely identify your browser or device. The cookies are placed on your browser or device when you visit a website. When you return to that website (or visit websites that use the same cookies) these websites recognize the cookies and your browsing device.

Cookies are widely used by website owners in order to make their websites work, or to work more efficiently, as well as to provide reporting information (for example, whether you have visited the website before).

2. Are there different types of cookies?

There are different types of cookies. Cookies set directly by the website owner (in this case, Chainguard, Inc.) are called "first party cookies". Cookies set by parties other than the website owner are called "third party cookies". Third party cookies enable third party features or functionality to be provided on or through the website (e.g. like advertising, interactive content and analytics). The parties that set these third party cookies can recognize your computer both when it visits the website in question and also when it visits certain other websites.

Cookies can remain on your device for different periods of time. Some cookies are "session cookies", meaning that they exist only while your browser is open and are deleted automatically once you close your browser. Other cookies are "permanent cookies", meaning that they survive after your browser is closed. They can be used to recognize your device when you open your browser and browse the Internet again.

3. Why do we use cookies?

We use first and third party cookies for several reasons:

Necessary: Some cookies are required for technical reasons in order for our Websites to operate, and we refer to these as "essential" or "strictly necessary" cookies. Without these cookies, we would not be able to provide you with the Websites and services that you have asked for.
Functionality: These cookies record information about choices you have made and allow us to provide relevant content and tailor our Websites for you.
Analytics: These cookies help us measure traffic and usage data to analyze how our Websites are used in order to provide you with a better user experience and maintain, operate and improve our Websites. They may also be used together with some of the advertising cookies described below to help show more relevant ads across the web and to measure interactions.
Advertising: These cookies are used to make advertising messages more relevant to you. They perform functions like preventing the same advertisement from continuously reappearing, ensuring that advertisements are properly displayed and, in some cases, selecting advertisements that are based on your interests.

4. What cookies do we use?

The specific types of first and third party cookies served through our Websites and the purposes they perform are described in the tables below. Please be aware that the cookies we use may depend on the Website you are visiting, the features you are using and the device, browser or operating system you are using.

5. What about other tracking technologies, like web beacons?

Cookies are not the only way to recognize or track visitors to a website. We may use other, similar technologies from time to time, like web beacons (sometimes called "tracking pixels" or "clear gifs"). These are tiny graphics files that contain a unique identifier that enable us to recognize when someone has visited our Websites or opened an e-mail including them. This allows us, for example, to monitor the traffic patterns of users from one page within a website to another, to deliver or communicate with cookies, to understand whether you have come to the website from an online advertisement displayed on a third-party website, to improve site performance, and to measure the success of e-mail marketing campaigns. In many instances, these technologies are reliant on cookies to function properly, and so declining cookies will impair their functioning.

6. Do you use Flash cookies or Local Shared Objects?

Websites may also use so-called "Flash Cookies" (also known as Local Shared Objects or "LSOs") to, among other things, collect and store information about your use of our services, fraud prevention and for other site operations. If you do not want Flash Cookies stored on your computer, you can adjust the settings of your Flash player to block Flash Cookies storage using the tools contained in the Website Storage Settings Panel. You can also control Flash Cookies by going to the Global Storage Settings Panel and following the instructions (which may include instructions that explain, for example, how to delete existing Flash Cookies (referred to "information" on the Macromedia site), how to prevent Flash LSOs from being placed on your computer without your being asked, and (for Flash Player 8 and later) how to block Flash Cookies that are not being delivered by the operator of the page you are on at the time). Please note that setting the Flash Player to restrict or limit acceptance of Flash Cookies may reduce or impede the functionality of some Flash applications, including, potentially, Flash applications used in connection with our services or online content.

7. Do you serve targeted advertising?

Third parties may serve cookies on your computer or mobile device to serve advertising through our Websites. These companies may use information about your visits to this and other websites in order to provide relevant advertisements about goods and services that you may be interested in. They may also employ technology that is used to measure the effectiveness of advertisements. This can be accomplished by them using cookies or web beacons to collect information about your visits to our Websites and other sites in order to provide relevant advertisements about goods and services of potential interest to you. The information collected through this process does not enable us or them to identify your name, contact details or other details that directly identify you unless you choose to provide these.

8. Cookie settings

Some of these cookies are essential and we cannot provide our Websites to you without them, but there are others that can be turned off. Please note that turning off certain cookies will disable some of the features available to you through our Websites. We cannot guarantee that your experience on our Websites will be as good as it could otherwise be.
