Hmm, I guess this then makes sense if we regard the app as a latent space projecting user's data, so its views are awaiting to be activated.

Seen this way, the app is basically communicating to the user: Hey I have "Your Pictures", "Your Cases", etc. Click to find out.

But to me the "My ..." variation also makes sense. e.g. In Photos app on macOS you will see "My Albums", "My Projects", and although they can be renamed, I don't think I created them.
