Downloading data to the mobile app

Hi, I find a feature in the Android app for downloading data. Where do the data saved btw? I cannot find it in my phone folder

Thank you in advance!

Epicollect5 data can be accessed only by the Epicollect5 app, not by any third-party apps, to ensure data security and consistency.

But where do the data saved in my phone?

Or, eventhough I downloaded the data from the android app to my phone, there’s no way I could find it in my folder?
