Constantly, until the day I moved out completely. Privacy only existed on paper. My room occasionally was searched while I was absent, and I only noticed because it was done sloppy (things were arranged differently). This was especially the case for all school related things, but included the occasional search for cigarettes and alcohol.

I'm really glad that the whole computer/ internet/ mobile phone/ social media thing started to happen while I was becoming an adult, and thus was on the brink of moving out. Maybe this helped me to spark a general interest in online privacy.

Sometimes at work we do have interns from a nearby school. They participate for two weeks, in order to prepare them for entering work force in a coulple of years, and to find out what these students are interested in. These students are around the age of 14 - 17 years old. To gain a school licence for our software we use at work, we make them to register with the software vendor to obtain such a temporary licence. This involves to register with the email adress they recieve from their school. Many of these interns struggle with that, because they cannot do this on their own, either, they don't know how to, or, because access within their phones is restricted by parental controls. One intern told me, that their parents regularly search their phone - and the worst part ist, that this is seen as completely normal to them! They already have been conditioned to constant surveillance that it would be weird to them if they were left unattended regarding this matter.

If my parents would have had access to my online activities (if availiable back then), they certainly would have had a field day.

I jokingly used to say: If we [my parents and I] lived in the GDR [Eastern Germany before the fall of the Iron Curtain], we woudn't just have had a car, but also a telephone. [The reason for this is that citizens who were actively involved in the suveillance of certain people, along with the spying of their neighbors and own families, were often members of the StaSi, and thus were rewarded for their loyality towards the party with a car whitout the long waiting time, and those who were within the party also would have had an own telephone at their homes as a reward for their loyal services.]
