Can Cryptomator read my files when connected to my cloud?

Hello,

Can Cryptomator read my files when connected to my cloud ? I trusted Cryptomator, But I aware of its security.

Thank you.

Access key/s to manage files on your cloud storage account never leaves Cryptomator app, so only Cryptomator app on your device gets access to the files on your cloud storage account. Cryptomator app uses this permission to manage vaults on your cloud.

We don’t have access to your cloud account, nor do we know which cloud account you use, because there is no intermediate server or service.

So, does this mean that even if I install Cryptomator on another phone, I still need to authenticate (log in again) in order to manage and access my cloud? And of course, the access tokens on the two phones would be different, right?

Are there any chance that Cryptomator could access files other than the encrypted ones in my cloud?
