​

• with the prior consent of the user before the  storage of information on his terminal or access to information already stored on it  ;

​​

• except  if these actions are strictly necessary for the provision of an online communication service expressly requested by the user or have the exclusive purpose of allowing or facilitating communication by electronic means.
