A '''local shared object''' ('''LSO'''), commonly called a '''Flash cookie''' (due to its similarity with an [[HTTP cookie]]), is a piece of data that websites that use [[Adobe Flash]] may store on a user's computer. Local shared objects have been used by all versions of [[Flash Player]] (developed by Macromedia, which was later acquired by [[Adobe Systems]]) since version 6.<ref name="adobe-lso">{{cite web

Flash cookies, which can be stored or retrieved whenever a user accesses a page containing a Flash application, are a form of local storage. Similar to cookies, they can be used to store user preferences, save data from [[Flash game]]s, or track users' Internet activity.<ref>[{{cite web|title=When the cookies crumbled, so did your web anonymity|language=en|website=The Guardian|date=2014-10-04|access-date=2023-12-28|url=https://www.theguardian.com/technology/2014/oct/05/cookies-crumbled-internet-anonymity The Guardian newspaper, When the |archive-url=http://web.archive.org/web/20230605133635/https://www.theguardian.com/technology/2014/oct/05/cookies -crumbled, so did your web -internet-anonymity, 5 October 2014]|archive-date=2023-06-05}}</ref> LSOs have been criticised as a breach of [[browser security]], but there are now browser settings and addons to limit the duration of their storage.
