Hello flanco,
right now we have no official support for PCloud.
However, Boxcryptor works with almost every cloud provider.
As long as you have a folder which gets synchronized you can easily add this folder as a Boxcryptor Location.
Please have a look at this tutorial:
https://www.boxcryptor.com/help/manage-cloud-providers-and-locations/
On mobile the situation is a little bit different, because we have to implement every provider by ourselves.
However, if PCloud supports webDAV, you can easily add it with our mobile apps.
As far as we know, PCloud started to support WebDAV.
You should be able to connect with these settings:
Link: https://webdav.pcloud.com
Port: 443
Username: {Your user name}
Password: {Your password}
I am sure that the PCloud support will be glad to help in case you have trouble connecting via webDAV.
PCloud is on our list of cloud providers which should be included, but I can neither say if nor when official support will be available.
Best regards,
Yasmin
