Building dropbox like app for photos and videos. Content has to be stored within the EU. Is it possible?

Hi everybody,

New to this and before going too deep I need to be sure that I can pick the storage solution of my choice for my dropbox-like web app.

Specifically, I need to make sure that photos and videos uploaded by the user(s) never leave the EU (for compliance reasons). Preferably I would like to store all photos and videos on Amazon S3. However, all is uploaded and downloaded through the bubble based app.

Is it possible?

Cheers
