Works great, but ...

It needs an update. Will no longer work with Box Sync (and possibly other cloud providers) when they are loaded as an additional provider. So far, still works with OneDrive.




Platform: Mobile

Great universal app

Extremely useful for encrypting files across multiple platforms and cloud resources. Highly recommended




Platform: Mobile

Totally useless...

Can't upload other files like docx, ppt, PDF, excel, rar, zip, and many others, just photos... Photos aren't a privacy problem for me, I don't like take pics. This app is just usefull for people who likes some "secret" photos (especially nudes or something more "private")...

Works well for reading encrypted documents. But I wish I could edit them from the app.




Good concept, but feels as if still in "beta"

Installed it on my Lumia 630. Works for decryption of encrypted files / folders if used with an account, but it does NOT work for local accounts. If i open a *.bckey file with Boxcryptor, the App opens a page with "Local Account" but the page is just white. Additionally if i try to upload files, the "Photo" app gets opened, which is quite uninteresting for me, I don't need to encrypt my photos normally. I really want to use this app, but currently it feels like a beta version, since there are some things missing i want to use (i.e. hold finger down -> encrypt / decrypt file / folder) and I won't use it on windows phone unless the local account works, since i want to store my private key locally.

Can only upload and encrypt photos from my Windows Phone. Would be a 5 if I could upload any file type, not just pics.
