When you use Google sites, apps, and services, a record of some of your activity is saved in your Google Account. You can easily access and control this activity , where you can find and... There are a few things to note before you start deleting all your Google activity history. Once you delete your Google history, you cannot recover it. Even if you delete the history, newer activity on your Google accounts and services may be automatically recorded. Go to myactivity.google.com in a web browser and select " Activity Controls." From there, you have the option to delete individual searches , large chunks of searches , and the ability to set up a recurring auto- delete schedule for your search history. If you want to delete my activity history, you need to delete it from your Google account. Clearing all the history from your account will delete the search history from all the devices you are logged in to, websites you have visited, and even the videos you have watched.
