Is there a recent-is review of the crypto it uses? I used to use Boxcryptor so I could have file-by-file encryption and sync directories full of encrypted files to various cloud storage services, but there was a know vulnerability with the way the crypto worked, were updates/changes to previously encrypted files could leak important info (I don't recall if it was cleartext or key hints?). It also had the problem of not encrypting directory names, so an attacker could see that you had a directory named "Plans For Super Secret Volcano Submarine Base" or "Darkweb purchase receipts".
