We do not pass any information to Google:
that Google could use or recognize as personally identifiable information; or
that permanently identifies a particular device (such as a mobile phone's unique device identifier if such an identifier cannot be reset).
We do not use Google AdSense to facilitate the merging of personally identifiable information with information previously collected as non-personally identifiable information without robust notice of, and the user's prior affirmative (i.e., opt-in) consent to, that merger.
