Abstract
An online system determines a frequency with which its users delete information stored in a browser on client devices associated with each user. When a user accesses the online system, the online system determines a user identifier associated with the user and determines if one or more conditions are satisfied based on information received from a browser used to access the online system. If a condition is satisfied, the online system communicates an instruction to the browser to communicate information associated with a third party and the user identifier to the third party. Information previously stored in the browser and associated with the user identifier is compared to information associated with the user identifier received from the browser. Deletion of information stored in the browser is determined when stored information associated with the user identifier differs from received information associated with the user identifier.
