Zeitgeist service comes pre-installed in Ubuntu and logs all activity such as files accessed, visited websites, etc. Activity Log Manager Zeitgeist is a GUI based application which lets you gain control of the information that Zeitgeist logs. It allows creating blacklists according to file or application type to disable logging for specified applications and user activities. This ensures that your personal information can be controlled from showing up in Zeitgeist logs. For example, you can use Activity log Manager to disabled logging for visited websites, certain file types (e.g. Libre Office files) and so on.
Activity log manager can be installed from the following PPA.
sudo add-apt-repository ppa:zeitgeist/ppa sudo apt-get update sudo apt-get upgrade zeitgeist-daemon --replace sudo apt-get install activity-log-manager
Once done, launch it from the Unity Dash. From the History tab you can select a time frame for deleting Zeitgeist history. This can be done according to specified hours, minutes, days weeks or only selected dates.
The Applications tab can be used to add applications to a block list. The added applications are no longer logged and their activity is not recorded by Zeitgeist.
Similarly, you can disable file types from being logged by specifying the kind of files which are to be added to the exception. The available file options include audio, video, instant messenger files, presentations, emails, spreadsheets, website data and images.
You can also download and compile the Activity Log Manager package from the Launchpad link given below..
