Flash Player local storage

Flash Player local storage refers to files that can be created that store information on your computer when you visit certain websites. They are sometimes incorrectly referred to as “Flash cookies” because, like browser cookies, they can be used to store information such as login data or pages that you’ve visited. Many websites use this feature to remember information such as form information entered in content using Flash Player, your online game progress or high scores, settings such as your preferred playback volume, or where you last left off when watching a video. The information stored in local storage remains on your computer after you close Flash Player (even if you clear your browser cache) and is available only to the website that stored it. That website may retrieve the information in the local storage the next time you visit that site. You can clear this information at any time using Flash Player Settings Manager. For more information on local storage see www.adobe.com/products/flashplayer/articles/lso.

What are the potential privacy issues?

It has been reported that some companies may be using Flash Player local storage to track users online in place of using HTTP cookies for that purpose. Some companies may also place a backup copy of HTTP cookies in local storage for use in the event the user deletes their cookies (this has sometimes been referred to as “respawning”). Adobe has publicly condemned the use of local storage in ways that are contrary to the user’s expressed intentions, but the nature of providing tools for an open platform means that we cannot control how developers and content producers use our products.
