If you're big on security (or keeping a secret), you might not want the Edge browser to keep a permanent record of the sites you browse. If that's the case, you can use a setting in Edge to automatically erase your history every time you quit the program.
1. Click ". " in the upper right-hand corner of the Edge browser.
2. Click "Settings."
3. Click "Choose what to clear" under "Clear browsing data."
4. Switch "Always clear this when I close the browser" on.
