In Saudi Arabia, there are a lot of things that are commonplace in Europe and illegal there.
Are immigration authorities known to inspect the files on computers and phones for things that would be considered against the morals? For example :
Intimate pictures that a couple may share with each other
Dating apps, especially those where people can exchange pictures through the messaging function
Would it be good advice to delete the pictures and uninstall those apps beforehand to someone who would need to travel into the country for business? Doing it would keep things on the safe side but risk a loss of contacts & messages history, for instance.
