The Historical Purge
Google Chrome is designed to keep your browser relatively lightweight by periodically cleaning out its own databases. By default, Chrome’s internal logic will silently and automatically delete any browsing history entries that are older than 90 days. While this prevents the history database file from growing to multiple gigabytes in size, it is a massive problem for researchers, journalists, or anyone who frequently needs to recall a specific, obscure webpage they visited six months ago for a project.
Leveraging the My Activity Portal
Unfortunately, Google does not provide a simple toggle switch within the local Chrome browser settings to stop this 90-day purge. To keep a permanent, searchable record of every webpage you visit indefinitely, you must rely on Google’s cloud-based “Web & App Activity” sync, which overrides the local browser limitations.
Ensure you are signed into your Google account in Chrome. Open a new tab and navigate to myactivity.google.com. In the main dashboard, click on the Web & App Activity panel. You will see an option labelled Auto-delete. Click this option to open the retention settings. By default, this might be set to delete activity older than 18 or 36 months, or it might be turned off entirely. To ensure your history is never purged, select the radio button labelled Don’t auto-delete activity. Click Next, then click Confirm. From now on, even when your local Chrome browser purges its 90-day cache, you can always visit the My Activity portal to search for webpages you visited years ago.
