With your permission, the new Microsoft Edge can remember information for you, making it easier to return to a favorite site or fill in forms. Microsoft Edge stores your browsing data, such as your passwords, info you've entered in forms, sites you've visited, and other information. Other browsing modes such as InPrivate browsing and Guest mode function differently and store less data than normal browsing.
Your browsing data is stored on your device. If you've turned on sync, those data types can also be stored in the Microsoft cloud to be synced across your signed in versions of Microsoft Edge.
You can see and clear your browsing history by selecting Settings and more > History > Manage history. You may choose to clear your browsing history at any time.
Clear browsing data stored on your computer
To clear browsing data on your computer, make sure sync is turned off. Items that are synced will be cleared across all synced devices.

Select Settings and more > Settings > Privacy, search, and services .
Under Clear browsing data, select Choose what to clear.
Choose a time range from the Time range drop-down menu.

Clear browsing data stored in the cloud (if you’ve turned on sync or personalization)
To manage and delete data saved in the Microsoft cloud, see the privacy dashboard. On the privacy dashboard you can view or delete your data. Data that you delete on the privacy dashboard won’t be deleted from your device.
To learn more about how to stop sharing your data with Microsoft, see Microsoft Edge browsing data and privacy.
