This code has been deprecated.
The Keep My Opt-Outs project is now part of the Digital Advertising Alliance Self-Regulatory Program. Google has worked with the DAA to include the Keep My Opt-Outs functionality in the DAA's Protect My Choices. Because of this, Google has ceased maintaining this project. You can still use the code as is under the applicable license(s), but this project is not going to accept or receive changes anymore.
