Irish regulators are seeking clarifications from Facebook after the world's largest social network informed users proposed plans to change its privacy policy.

Facebook proposed a number of changes to its data governance and privacy policy on Wednesday, including its data-use policy and its statement of rights and responsibilities.

Among other, the changes could open the door for the company to build unified profiles of its users that include people's personal data from its social network and from Instagram. In addition, Facebook proposed to eliminate a setting for users to control who can contact them and add new filters for managing incoming messages instead.

Facebook's anouncement Facebook could not be overseen by the Irish data protection regulators, which is Facebook's regulator in Europe.

"We will be seeking urgent further clarification from Facebook Ireland and if we consider that the proposed changes require a specific consent from EU users we will require Facebook to do this," Gary Davis, Ireland?s deputy data- protection commissioner, told Bloomberg.

Facebook says it remains in contact with the Office of the Irish Data Protection Commissioner to ensure that the company maintains high standards of transparency.

The Irish regulator in September concluded a review. into Facebook that pushed the owner of the biggest social-networking site to delete data collected from users within the EU for its facial-recognition feature.
