Simple Opt Out is drawing attention to opt-out data sharing and marketing practices that many people aren't aware of (and most people don't want), then making it easier to opt out. Target "may share your personal information with other companies which are not part of Target." Chase may share your "account balances and transaction history … For nonaffiliates to market to you." Crate & Barrel may share "your customer information [name, postal address and email address, and transactions you conduct on our Website or offline] with other select companies." This site makes it easier to opt out of data sharing by 40+ companies (or add a company). Enjoy!
