Identifying users

Publishers must:

• not pass any information to Google data that Google could use or recognize as personally identifiable information
• not use our services to identify users or 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 identification or merger. Irrespective of users' consent, you must not attempt to disaggregate data that Google reports in aggregate.

  For more information, please refer to Guidance for complying with the Identifying Users Policy.

• comply with the EU user consent policy.
