thank you for your interest in Boxcryptor!
I would like to help you understand Boxcryptor and how to use Boxcryptor to secure and encrypt your cloud storage.
Boxcryptor provides a cilent-sided encrypted. That means your files get encrypted before they are stored within the cloud.
Within the cloud storage (Google Drive), only encrypted files are hosted.
If you want to access these files, you access these files via Boxcryptor and they get decrypted on-the-fly.
If you want to use Boxcryptor on different devices (more than two) you have to purchase Boxcryptor Unlimited Personal License in order to use more than two devices.
Boxcryptor is available for all main platforms.
You can learn more about how to setup Boxcryptor here: https://support.boxcryptor.com/display/DOCEN/Boxcryptor+2.0+Documentation
