Question

How to completely clear localstorage  sessionStorage and cookies in javascript    Is there any way one can get these values back after clearing them

User · Answer

The standard Web Storage  does not say anything about the restoring any of these  So there won t be any standard way to do it  You have to go through the way the browsers implement these  or find a way to backup these before you delete them

There is no way to retrieve localStorage  sessionStorage or cookie values via javascript in the browser after they ve been deleted via javascript   If what you re really asking is if there is some other way  from outside the browser  to recover that data  that s a different question and the answer will entirely depend upon the specific browser and how it implements the storage of each of those types of data   For example  Firefox stores cookies as individual files   When a cookie is deleted  its file is deleted   That means that the cookie can no longer be accessed via the browser   But  we know that from outside the browser  using system tools  the contents of deleted files can sometimes be retrieved     If you wanted to look into this further  you d have to discover how each browser stores each data type on each platform of interest and then explore if that type of storage has any recovery strategy
