A controller is a person, company or association that decides how and for what purposes your personal data is processed. A hobby club can be a controller, for example. If you play ice hockey, your club is probably a controller, because it has information about you, such as your name and maybe your contact details.
You yourself are called a data subject. In your hobby, you are a data subject whose personal data is processed by the hobby organiser, such as your sports club.
