### Summary

Where is the original vault located?

### Motivation

Sometimes can happens that I manually do a vault copy in another volume, for example Anemo or Aer (fdroid), and can happen that I am not sure on which of these is the original one.

So, where is located the original vault?
Is it a mistery or a user can knowing this info through the app itself?
