During your registration you grated us permission to
"CloudWok would like access to its own folder, Apps › CloudWok, inside your Dropbox."
"Have offline access"
"Read and write all files and folders"
First – those permissions are only used for the programming logic to work. So it will always be the system creating a folder or accessing your files. Individual persons do not have any chance to access your Cloud!
Second – how exactly are the permissions uses?
Triggered manually by your creating a new CloudWok or when changing the target folder of a Wok.
Derive folder structure:
Triggered by any upload from the upload page
Only possible right after an upload in case the user sees that she/he just uploaded a wrong file. Not deletion possible after an upload session is closed.
Via the download tab on the upload site (in case you activated this). This only applies for the files available in the linked folder in your Cloud. No other files in your Cloud may be accessed.
