Rephrasing

   Sometimes Advanced Privacy indicates a tracker being loaded by the System. It's because in /e/ OS Progressive Web Apps (PWA) are managed by PWAPlayer, which is a system app. PWAPlayer does not load any trackers by itself but the websites browsed using PWAPlayer may load their trackers, which are ultimately blocked by Advanced Privacy.

   If any app (including system apps) load any trackers, the Tracker Blocker will block it. We do not intend to use/promote any services that attempt to track you, and we are actively developing better solutions to address these challenges.

4. Sometimes users get confused when they see a domain being listed as a tracker by Advanced Privacy, but not by filter lists (like Exodus). This happens because some websites/applications may add, remove, or modify their trackers over time. It is also possible that some trackers (i.e. tracking domains) will change their behaviour and stop tracking users. These changes become part of the filter lists when they are updated. In situations like this, trackers won't disappear from Advanced Privacy so as to reflect the domain's historical nature.

5. Advanced Privacy in /e/OS determines tracking domains using AdAway and Exodus filter lists. Most of these trackers are from analytical services used by app developers, but occasionally a company that offers a variety of services can act as a third-party tracker in other apps. As an example, Microsoft uses one of its subdomains, login.microsoftonline.com, to allow users to log in to Microsoft apps, but according to Exodus,  [the same subdomain is also used by Microsoft to track users in third-party apps](https://reports.exodus-privacy.eu.org/en/trackers/63/). In situations like this, Advanced Privacy finds it difficult to determine whether a domain is being used to track a user or if the user is willingly using a service that uses the same domain. Developing a technical solution is difficult here as the context of user action is lacking. Nonetheless, we are currently evaluating options for dealing with those situations. In the meantime, [you can disable blocking of specific domains for specific apps in the Advanced Privacy settings](/support-topics/block-unblock-trackers-per-app).

4. Over time, trackers (i.e. tracking domains) may stop tracking users or change their behavior. These changes are adopted into filter lists (like Exodus) during their updates. However, these trackers won't disappear from Advanced Privacy to reflect the tracking domain's historical nature.

5. Advanced Privacy in /e/OS uses AdAway and Exodus filter lists to identify tracking domains. That means Advanced Privacy will block domains present in those filter lists. In rare cases, this process of blocking trackers may lead to some inconvenience. As an example, one of Microsoft's subdomain `login.microsoftonline.com` severs multiple purposes. Firstly, it allows Microsoft users to log in to Microsoft apps, but according to Exodus, [the same subdomain is used by Microsoft to track users in third-party apps](https://reports.exodus-privacy.eu.org/en/trackers/63/). In such cases, Advanced Privacy can't determine if a user is willingly using a service or is being tracked. We are currently evaluating options for dealing with situations like this, but in the meantime, [you can allow specific domains for specific apps in the Advanced Privacy settings](/support-topics/block-unblock-trackers-per-app). So, even in rare cases, you can enjoy the services you use without compromising on privacy across other apps.
