Google Drive Access - what Data will be used?

Please help me understand how my Data will be used when allowing Google AI Studio Drive Access - will Google AI Studio only use this Access to save Prompt files? Or will it use my documents/files on drive to train AI Models?
As far as I know only files I actually add to a prompt and submit will be used by Google to fine tune AI Models, am I correct in this?
How does this change when in EWR-Countries - if I read the privacy policy correctly data uploaded from the EWR Region will not be used in training, correct?
Thank you for your help!

Hi @Kajetan_Abele, Welcome to the forum!

Once you provide drive access, Google AI Studio won’t use any of your documents/files to train AI Models.

Yes, you are correct if on free tier and not using enterprise grade.

Sometimes privacy policies depends on country to country also, so you should follow that.
