Want a quick start? Take a look at this very simple example: Changes to Google Picasa privacy policy from March 30, 2006. Or the change in Google Talk Privacy performed in 2009, where Google is keeping track of all your SMS.

What is GooDiff and how does it help me ?

Short answer

GooDiff is a service for automated tracking of semantic changes in web service policies.

Long answer

The problem

The Internet is composed of various services available to potential users and consumers (read: you and I). These services are quite different from each other and they are offered to users in a multitude of ways. Still, they all have one thing in common: they come with a large amount of legal information. The legal documents are often evolving over time, and it can be very difficult for end users to find out what has changed, when and to which extent.

In fact, users are often required to inform themselves of any document changes. Here is an excerpt of the Gmail Program Policies (as of March 17, 2006):

To uphold the quality and reputation of Google Gmail, your use of Gmail is subject to these program policies. If you are found to be in violation of our policies at any time, as determined by Google in its sole discretion, we may warn you or suspend or terminate your account.

Please note that we may change our policies at any time, and pursuant to our Terms of Use, it is your responsibility to keep up-to-date with and adhere to the policies posted here.

As you can see, ignorance of service changes might have serious consequences.

GooDiff to the rescue!

GooDiff is a simple service which monitors important documents of service providers and keeps track of their changes and indirectly the changes of the services described therein. With GooDiff, users can find out if the legal documents are (still) respecting their privacy and personal rights. It's all about users, and transparency.
