1. Load the devices page. (login with your subscribed account)

2. Click the device name to expand its settings

3. Slide the blur slider to the level you wish to use.

4. Click Save in the bottom right-hand corner.

   

5. Restart the device to have the new blur setting take effect immediately. Otherwise it will take effect within a few minutes.

Changing image blurring settings is not retroactive, since the blurring occurs on the monitored device itself prior to sending the screenshots anywhere.
