In contrast, Dropbox keeps a copy of your encryption keys, which they use to access, scan, and share your files with trusted third parties. This is all part of the terms of service you agree to in order to use their service. Hard to believe? Read the TOS!
If you're storing sensitive, personal or confidential data with Dropbox, keep in mind, you're not the only one who has access to your files!
For far too long, and without knowing it, people have traded away their complete security and privacy when storing their content in the cloud. Sync still believes in your complete privacy, and has built a cloud storage platform based on that foundation. While it may be common knowledge that encryption is the most reliable way to secure information on the Internet, it’s meaningless if your cloud service provider keeps a copy of your encryption keys.
Just like Dropbox, Sync makes it easy to share and access your files from any computer, phone, or tablet - but with security and privacy built in at every turn. With support for Mac, Windows, Android and iOS it’s easy to get up and running.
