Is there a separate client that resides on the actual USB drive?

I read an article that noted that Cryptomator was a good cross platform utility to encrypt data on a USB drive. Since I live in the iOS, Windows, OSX & Linux worlds almost daily, I was wondering if part of the application lives on the actual USB drive? Is there some online documentation I’m missing?

Thank you

No. There’s no app data stored where your vault is stored. So if you use an usb stick as your vault storage, then only the vault is on the stick.

If you are locking for documentation: https://docs.cryptomator.org/
