Security & Privacy

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

• Shared folders are viewable only by people you invite.

• 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

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.
