Cookies are small files, typically of letters and numbers, downloaded onto your computer or mobile device when you visit certain websites. When you return to these websites, or visit other websites that use the same cookies, the websites recognize these cookies and your browsing device. A cookie cannot read data off your hard drive or read cookie files created by other websites.
Cookies set by the website operator are called "first party cookies". Cookies set by parties other than the website operator are called "third party cookies". The parties that set third party cookies can recognize your web browser both when it visits the Coinbase website and when it visits certain other websites where the third party’s cookies are also present.
When you access our Sites and Services, we or companies we work with may place cookies on your computer or other device. These technologies help us better understand user behavior, and inform us about which parts of our websites people have visited.
We use first party and third party cookies to recognize you as a Coinbase customer, customize Coinbase Services, content, and advertising, to measure promotional effectiveness, and to collect information about your computer or other access device to mitigate risk, help prevent fraud, and promote trust and safety.
The following are some examples of information that we collect and how we may use it:
We may collect and store details of how you use our Sites and Services. Except in limited instances to ensure quality of our Services over the Internet, such information will not be associated with your IP address.
We may collect information such as your language, inferred zip code or area code, unique device identifier, referrer URL, location, and time zone so that we can better understand customer behavior and improve our Services.
We use the following types of cookies:
These cookies are necessary for the Sites to function and cannot be
switched off in our systems. They are usually only set in response to
actions made by you which amount to a request for services, such as
setting your privacy preferences, logging in, or filling in forms.
These also include cookies we may rely on for fraud prevention. You can set your browser to block or alert you about these cookies, but some parts of the site will not then work.
These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our Sites. They help us to know which pages are the most and least popular and see how visitors move around the site. All information these cookies collect is aggregated and therefore anonymous. If you do not allow these cookies we will not know when you have visited our site, and will not be able to monitor its performance.
These cookies allow us to remember the choices you make and to tailor our Services so we can provide relevant content to you. For example, a functionality cookie can remember your preferences (e.g., country or language selection), or your username.
Coinbase uses third party service providers to display advertising on our Services and serve advertising on other third party sites that may be relevant to you or your interests. These cookies are also used to help measure the effectiveness of the advertising campaign. They remember that you have visited a website and this information may be shared with other organizations, such as advertisers. This means that after you have been to our websites, you may see some advertisements about our Services elsewhere on the Internet. The information collected through this process by the third party service providers does not enable us or them to identify your name, contact details or other personal information that directly identifies you unless you choose to provide these. Such advertising will only be delivered where permitted by applicable law. If you do not allow these cookies, you will experience less advertising tailored to your inferred interests on our Sites and will not receive targeted Coinbase advertisements on third party websites.
The length of time a cookie will stay on your browsing device depends on whether it is a "persistent" or "session" cookie. Session cookies will only stay on your device until you close your browser. Persistent cookies stay on your browsing device until they expire or are deleted.
In addition to cookies, we may use other similar technologies, like web beacons to track users of our Sites and Services. Web beacons, or "clear gifs," are tiny graphics with a unique identifier, similar in function to cookies. They are used to track the online movements of web users.
In contrast to cookies, which are stored on a user's computer hard drive or device, clear gifs are embedded invisibly on web pages and are about the size of the period at the end of this sentence. We and our third-party service provider employ web beacons for the reasons stated above (under "Cookies"), but primarily to help us better manage content on our Services by informing us which content is effective.
We may also use so-called "Flash Cookies" (also known as "Local Shared Objects or "LSOs") to collect and store information about your use of our services, fraud prevention and for other site operations.
You have the right to decide whether to accept cookies. You can exercise your preferences in relation to cookies served on our Sites by taking the steps outlined below.
Cookies. You can enable or disable categories of cookies by visiting our Cookie Consent Manager. This includes both first party and third party cookies. You can also use the browser with which you are viewing this website to enable, disable or delete cookies. To do this, follow the instructions provided by your browser (usually located within the "Help", "Tools" or "Edit" settings), or review the instructions provided by the browsers listed here: Internet Explorer, Google Chrome, Mozilla Firefox, Safari Desktop, Safari Mobile, and Android browser. Please note, if you set your browser to disable cookies, you may not be able to access secure areas of the Sites and Services. Also, if you disable cookies other parts of the Services may not work properly. You can find more information about how to change your browser cookie settings at http://www.allaboutcookies.org.
There are also additional tools available to manage third party cookies. Many advertising companies that collect information for interest-based advertising are members of the Digital Advertising Alliance (DAA) or the Network Advertising Initiative (NAI), both of which maintain websites where individuals can opt out of interest-based advertising from their members. To opt-out of website interest-based advertising provided by each organization’s respective participating companies, visit the DAA’s opt-out portal available at http://optout.aboutads.info/, the DAA of Canada’s opt-out portal available at https://youradchoices.ca/en/tools, or visit the NAI’s opt-out portal available at http://optout.networkadvertising.org/?c=1. Residents of the European Union may opt-out of online behavioural advertising served by the European Interactive Digital Advertising Alliance’s participating member organizations by visiting https://www.youronlinechoices.eu/.
Mobile Advertising: You can opt out of having your mobile advertising identifiers used for certain types of advertising by accessing the appropriate settings in your mobile device and following the instructions. If you opt-out, we will remove all data about you and will not collect any further data. The random ID previously assigned to you will be removed. Thus, if at a later stage, you decide to opt-in, we will be unable to continue and track you using the prior ID and you will for all practical purposes be a new user. For iOS devices, to limit interest-based ad tracking, go to Settings > Privacy > Advertising > Turn on “Limit Ad Tracking.” For Android devices, go to Settings > Google services > Ads > Turn on “Opt out of Ads Personalization." For iOS and Android, you can also reset the advertising identifier that is currently assigned to you.
To opt-out of data collection for interest-based advertising across mobile applications by participating companies, download the DAA’s AppChoices mobile application opt-out offering here: https://youradchoices.com/appchoices.
Do Not Track: Some Internet browsers - like Internet Explorer, Firefox, and Safari - include the ability to transmit "Do Not Track" or "DNT" signals. Since uniform standards for "DNT" signals have not been adopted, our Sites do not currently process or respond to "DNT" signals.
Flash Cookies. 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, available here: http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager07.html. You can also control Flash Cookies by going to the global storage settings panel and following the instructions. 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.
