Closing a website does not mean that all information about a user’s presence there is also erased. A user may close the page after finishing a browsing session and assume their connection to the site is over, but some of the data related to searches, visits, clicks, user accounts, and the device used can still remain in various places.
Websites and digital services use various identifiers and data to provide services, preserve user settings, analyze visitor behavior, and manage accounts. For this reason, users’ online activity is much more continuous than what is merely seen on the screen.
End of browsing is not the end of data
When entering a website, different information about the user’s session may be recorded; including the pages viewed, the time spent on each page, and some settings related to the device and browser.
This information can have various uses. Services use some of these data to run essential features, store user settings and preferences, check page performance, identify technical issues, and improve user experience.
In some cases, the information from a visit can be linked to a specific account or profile. In such circumstances, the recorded data is no longer related merely to an anonymous visit and becomes more closely associated with a particular user.
Cookies are not the only tracking tool
Cookies are one of the best-known technologies for identifying users and remembering some information about them, but they are not the only tools used by websites.
Today’s services and apps also use other technologies to store settings, manage account sign-in, identify sessions, and measure user engagement.
On the other hand, some services may retain account-related information for a longer period; especially when this information is necessary to continue providing services, maintain security, or prevent fraud.
Therefore, removing a cookie from the browser does not necessarily mean that all information about previous activities has been erased. Some of these data may still be stored on the service’s servers.
Why do companies keep user information?
Storing user information is not always done for a single purpose. Some of the data are essential for account sign-in and service provision, while other data help companies understand how users use the service, identify technical problems, and find areas for product improvement.
Recorded data can also be important for maintaining security. For example, security logs may be used to detect unauthorized access attempts or unusual activities. Some services are also required by technical or legal obligations to retain certain information for a specified period.
In advertising and personalized services, data related to user activity can be used to understand their interests and deliver more relevant content or ads aligned with their behavior.
Deleting an account does not mean all data disappear immediately
The fate of information after account deletion or the end of a user’s activity depends on each service’s policies. Some data may be deleted immediately, but other information may remain for a time in backup systems, technical reports, or other parts of the infrastructure and be deleted later.
Companies may also retain certain information under their policies and laws for legal, security, or abuse-prevention reasons. Therefore, the deletion timing of data is not the same across all services.
How to reduce your digital footprint
Users can reduce the amount of data they leave across services with a few simple actions. Regularly reviewing privacy settings, deleting cookies and browsing history when needed, limiting permissions granted to websites and apps, and reviewing old accounts are actions that can help reduce the digital footprint.
It is also better to delete accounts that are no longer in use where possible. However, it should be noted that deleting information from a device or browser does not necessarily mean the same data are deleted from the service’s servers.
Ultimately, digital activity cannot be thought of like a piece of paper that can be torn up and destroyed after use. Each visit may create a set of records across different layers, and some of this information, depending on the type of service and data management practices, may remain for a period.
With users’ increasing reliance on online services, awareness of where data are stored, why they are retained, and when they are deleted has become an important part of understanding privacy. Digital traces may remain in digital infrastructures long after a user no longer even remembers visiting a website.
