In today's digital world, our online activities generate vast amounts of data. This data is collected and used by websites and services for various purposes, from personalizing content to delivering targeted advertising. Understanding how this process works is crucial for navigating the internet with awareness.
When you visit a website or use an application, your device shares certain information. This can include precise location data and specific device properties. These details help to identify your device each time it connects to an online service.
Key Takeaways
- Websites collect device information and location data.
- Data is used for personalized ads, content, and service improvement.
- Cookies track site performance and user behavior.
- User profiles are built to deliver relevant experiences.
- Users have choices regarding data sharing.
How Data Collection Works
Data collection begins the moment you interact with an online service. This interaction triggers the storage and access of information on your device. Various identifiers, such as login-based identifiers, randomly generated IDs, or network-based identifiers, play a role. These work alongside other details like your browser type, language settings, and screen size.
Device Identification and Tracking
Each time your device connects to an app or website, these identifiers help recognize it. This recognition is fundamental for the processing purposes outlined by service providers. It allows for a continuous and personalized online experience.
Did You Know?
The average internet user interacts with hundreds of websites and apps each month, each potentially collecting various data points.
The Role of Cookies and Online Identifiers
Cookies are small pieces of data stored on your device. They are essential for website functionality. Some cookies are necessary for the site to work correctly, handling tasks like privacy settings, login information, or form submissions. Blocking these can impact site performance.
Measuring Site Performance
Other cookies help measure website performance. They count visits and traffic sources. This information allows website operators to understand which pages are most popular and how visitors move through the site. All data collected by these performance cookies is aggregated and anonymous, providing general insights without identifying individual users.

Personalization and Targeted Advertising
Advertising partners often place cookies through websites. These cookies build a profile of your interests. They do not store direct personal data but rely on unique identifiers for your browser and internet device. This profile then helps display relevant ads on other websites.
Building User Profiles
Information about your activities, such as forms you submit or content you view, can be combined with other data. This includes past activity on the service or other websites. This creates or enhances a user profile, which may include potential interests and personal characteristics. This profile helps companies present advertising more relevant to your likely interests.
Context: Data Aggregation
Data aggregation involves combining various datasets, such as user profiles, statistics, market research, and analytics. This process helps create reports on user interactions with advertising or content, identifying common characteristics and target audiences.
Content Personalization and Engagement
Beyond advertising, data also personalizes the content you see. Content profiles, based on your activities and interests, determine the order in which content appears. This aims to make it easier for you to find non-advertising content that matches your interests.
Measuring Content Effectiveness
Information on how you interact with content helps determine its effectiveness. This includes whether you read an article, watched a video, or listened to a podcast. It also tracks the time spent on a service or specific webpages. This data helps assess the relevance of non-advertising content presented to you.
- Exact Geolocation Data: Used with consent, within a 500-meter radius, to support various purposes.
- Device-Specific Characteristics: Requested and used with consent to distinguish your device from others (e.g., installed fonts, plugins, screen resolution).
- Fraud Prevention: Data monitors and prevents unusual or fraudulent activities, ensuring system security.
- Technical Compatibility: Information like IP address ensures content and advertising are technically compatible with your device.
Data Linkage and Device Association
Your activity data can be combined with other information from different sources. This includes activities on other online services, in-store loyalty card usage, or survey responses. This comprehensive data helps enhance the purposes explained by service providers.
Cross-Device Linking
It can also be determined if your device is likely linked to other devices you or your household own. This might be because you are logged into the same service on both your phone and computer, or because you use the same internet connection for multiple devices. This cross-device linking contributes to a more cohesive user profile.
Ultimately, the automatic transmission of information by your device, such as your internet connection's IP address or browser type, helps distinguish it. This information is crucial for delivering a tailored and functional online experience.
