Microsoft Editor - Data protection

When using Microsoft Editor, Microsoft Edge sends your typed text and a service token to a Microsoft cloud service over a secure HTTPS connection. The service token doesn't contain any user-identifiable information. A Microsoft cloud service then processes the text to detect spelling and grammar errors in your text. All your typed text that's sent to Microsoft is deleted immediately after processing occurs. No data is stored for any period of time.

In the settings page of Microsoft Edge, if you select Basic instead of Microsoft Editor, Microsoft Edge will perform only local spellchecking on the device, and no data will be sent to the cloud for spellchecking services.

To use Basic spelling and grammar checking:

1. Go to edge://settings/languages.
2. In the Use writing assistance section, select Basic.

To turn off all spelling and grammar capabilities:

1. Go to edge://settings/languages.
2. Turn off the Use writing assistance toggle.
