Security & Privacy

Dropbox takes the security and privacy of your files very seriously.

• Shared folders are viewable only by people you invite.
• All transmission of file data and metadata occurs over an encrypted channel (SSL).
• All files stored on Dropbox servers are encrypted (AES-256) and are inaccessible without your account password.
• Dropbox website and client software have been hardened against attacks from hackers.
• Dropbox employees are not able to view any user's files.
• Online access to your files requires your username and password.
• Public files are only viewable by people who have a link to the file(s). Public folders are not browsable or searchable

File Sync

Dropbox allows you to sync your files online and across your computers automatically.

• 2GB of online storage for free, with up to 100GB available to paying customers.
• Sync files of any size or type.
• Sync Windows, Mac and Linux computers.
• Automatically syncs when new files or changes are detected.
• Work on files in your Dropbox even if you're offline. Your changes sync once your computer has an Internet connection again.
• Dropbox transfers will correctly resume where they left off if the connection drops.
• Efficient sync – only the pieces of a file that changed (not the whole file) are synced. This saves you time.
