Is watching YouTube in an app private?

The app on my iPhone can the videos I watch be monitored and released what videos I was watchinh

You have a YouTube watched history, if you don't clear that then somebody who has access to your account can view your watch history

Nothing is really private since Google and the government is still spying on you through YouTube.

No. There are a dozen different ways that a person could determine what you are viewing on YouTube. Including the viewing history on your phone, the viewing history on your YouTube account, the metadata at your phone provider (if you are their Wi-Fi), the history/metadata at your ISP (if using your PC Wi-Fi), etc.

However none of them are things the average user would know how to do. Or they require a court order to view the information.

I don't know but i doint think youll be harmed watching it

Depends on if that app is signed into your YouTube account as well. If not, then it is off the record basically.

Yes
