ItsMyData for Chrome helps perform opt-outs to prevent online merchants from selling your data.

Online merchants are not fond of providing consumers more control over their personal information that businesses collect about them as required by law. They comply but begrudgingly and make the process as complicated as possible by sometimes burying the opt-out links so deep that the average consumer will never find them. This is where ItsMyData comes into play. ItsMyData will do the dirty work of locating the opt-out and then opting-out for you.

Additionally, ItsMyData will let you know if a site is or isn't an e-commerce site and if an opt-out is even available.

ItsMyData Features:

Opt-out automatically

This spares you the need to look for the opt-out process and go through complicated requirements set by the merchants
Never sell your data

They will not sell your data or provide it to third parties (except if required by law). You can always leave, and the record will be deleted at your request
Opt-in when you want

Want a certain vendor to have your data? Opt-in instead of having to opt-in from multiple other vendors
