Welcome to Vodafone Community
@gipjon Are you referring to the Private Message function here on the forum? Or are you querying the privacy of your messages on your phone using the Vodafone network?
@gipjon So the Private Message function is in fact private. However, as admins we reserve the right to view any messages our users may have should we have sufficient reason to do so. I can assure you we wouldn't typically ever look into the private messages exchanged between users, nor can staff randomly just out of curiosity either.
