Cookies are text files that contain data from visited websites or domains and are stored by a browser on the user’s computer. A cookie is primarily used to store information about a user during or after his visit within an online offer. Stored information may include, for example, language settings on a website, login status, a shopping cart, or where a video was watched. The term cookies also includes other technologies that perform the same functions as cookies (e.g., when user information is stored on the basis of pseudonymous online identifiers, also referred to as “user IDs”).
The following cookie types and functions are distinguished:
- Temporary cookies (also: session cookies): Temporary cookies are deleted at the latest after a user has left an online offer and closed his browser.
- Permanent cookies: Permanent cookies remain stored even after the browser is closed. For example, login status can be saved or preferred content can be displayed directly when the user revisits a website. Likewise, the interests of users used for reach measurement or marketing purposes may be stored in such a cookie.
- First-party cookies:First-party cookies are set by us.
- Third-party cookies:Third-party cookies are mainly used by advertisers (so-called third parties) to process user information.
- Necessary (also: essential or absolutely necessary) cookies: Cookies may be absolutely necessary for the operation of a website (e.g. to store logins or other user input or for security reasons).
- Types of data processed: Usage data (e.g. websites visited, interest in content, access times), meta/communication data (e.g. device information, IP addresses).
- Data subjects:Users (e.g., website visitors, users of online services).
- Legal basis:Consent (Art. 6 para. 1 p. 1 lit. a DSGVO), Legitimate Interests (Art. 6 para. 1 p. 1 lit. f. DSGVO).
