The AVG is for personal data. In other words, data that you store or process that is directly related to people. Think of name and address data with bank account numbers or, for example, data about sick leave, insurance, remuneration, etc. That you have this data or process it is not the problem. But not thinking about who can see it or who can provide access to it or how it is stored and backed up, that's exciting. By thinking about this and gaining insight, you can design adequate processes.
