DoNotTrack is a property set in the Navigator. This means that users can turn this setting on to avoid being tracked.

But in fact, you can't "avoid tracking" because most sites don't obey this setting at all. Instead, they use it as an additional data point to improve the accuracy of the user's fingerprint recognition.

In VMLogin, the default value of "Do Not Track " is "not set " or unspecified, which means that the user has not made any active choice in advance. This is more in accordance with the behavior of the vast majority of Internet users.
