If you don't want to leave the safeguarding of your Chrome browser history to Google, you can make backups yourself.
A browser history backup is useful if you accidentally delete your Google Account data, as it will erase your entire browser history from every device you were signed in to. The only way to get your browsing history data back at that point is to use a local backup.
Creating a browser history backup is simple. Google Chrome automatically saves your browsing history to a MySQL database file on your computer. You just need to copy that file to a desired safe location.
Whenever you want to restore the browser history backup, simply copy that file again to the Chrome folder and replace the existing database. This is how it works!
Backup Google Chrome browser history without Google account
Close the Google Chrome browser and open Windows Explorer.
Go to the folder:
C:\Users\Username\AppData\Local\Google\Chrome\User Data\Default\
(replace Username by your Windows username).
Copy the “History” file. This is the database with the Google Chrome browser history. Place the History file in a safe location. It is recommended to regularly back up this History file.
The next time you want to restore your browser history, copy the saved History file and overwrite it in the folder where the History file came from.
You have now secured Google Chrome browser history without a Google account. Thank you for reading!
