Can advertisers have access to user data? Will these data be used by advertisers for their own purposes?
What exactly do you mean? What kind of personal data are you talking about and how can they be passed on to the advertiser?
Well, for the display of contextual advertising, certain information about the user will be collected and transmitted to the advertiser, am I right? Or will it work differently?
It depends on what kind of personal data you mean. Yes, advertisers will be able to access a portion of the user's personal data, but only with the consent of the users and on the terms of the advertiser.
