Hi, For privacy reasons I would love to be possible to save my files using the cloud service Tresorit instead of Dropbox. Is it possible?
Yes - it doesn't look as though there is an API available. There look to have an iOS library that was discontinued back in 2018, but I don't think it offered that same sort of control you get with Dropbox, Box or WebDAV.
I'm a BeOrg user and a Tresorit user too, but I don't think it can be an option because Tresorit doesn't have APIs.
