Short answer: No—being the YouTube Premium family manager doesn’t give your parents access to your watch or search history. They can manage billing and members, that’s it.
Things to watch out for:
- Shared devices/TVs: if your account’s signed in, anyone can see your history there.
- Supervised (Family Link) accounts: parents get more control/restrictions; not Premium-related, but they may have some visibility/control.
- If they know your Google password or you share an account, they can see everything.
Quick fixes:
- Use your own Google account, sign out on shared TVs, or use YouTube’s Incognito/Pause watch history.
- Check your history settings at myactivity.google.com and YouTube app > History > controls.
