Can my parents see when I'm on Netflix?

So if, for example, I watched Netflix until 3 a.m., you can see that I was on Netflix at 3 a.m. The next day?

Yes, the time when a device was active on Netflix is logged and can be viewed in the account management.

Can that be prevented?

Everything is logged, really everything, every single click, every film start, every stop, every rating, just about everything. You can request the data via the settings.
