Turn Dropbox into a private, encrypted pipeline for your files.

How it helps

Now you can safely sync your confidential files. We use client-side encryption to give you absolute privacy and control over your data.

How you can use it

Secure synchronization

SecretSync is a great way to easily share proprietary, sensitive information using online synchronization utilities like Dropbox.

Offsite backup

Even if you're not synchronizing, you can still use SecretSync to create an instant, secure, offsite backup. You can use it to backup financials, tax info, or any sensitive personal and business information you may have.

How it works

New! See the Getting started guide for more details.

We add an additional folder to your computer, a SecretSync folder. Anything that gets put in SecretSync is encrypted and then added to Dropbox to be synchronized to your other computers.

Before your files are synchronized by Dropbox to your other computers, they're encrypted with 256-bit AES encryption, using a key to which only you have access. The files are only decrypted on the other end — that is, on your other computers.

Your files are always encrypted when online. This means that before your files leave the computer you physically control and own, they're encrypted. They stay encrypted while being synchronized, until they're back in your physical control.

This is a beta release for Windows. (Linux and OS X coming soon.)

Doesn't Dropbox use encryption?

Yes. Dropbox takes every precaution to keep your data secure. They use SSL encryption to make sure that while you send your files to them, the network packets can't be compromised. Once they receive your files, they store them encrypted on their servers. They also use internal policies to ensure that employees can't access your files.

The difference is that we provide client-side encryption, while Dropbox provides encryption at the server. This just means that we're not asking you to trust us, or anyone, with your data. Your computer encrypts your files first, before anyone else has a chance to access them.

Dropbox is an excellent company with its user's interests at heart. We simply provide an additional layer of privacy and security to an already great, and secure, service.
