You can add or edit information in your Skype profile such as your location, email, or phone number to make it easier for friends to find you. If you prefer not to be included in the public search directory or suggested friend's, then you can opt out. Opting out will make you completely unsearchable to anyone.
To opt out of being discoverable in Skype search:
- Select your profile picture.
- Select Application Settings, then scroll down to Privacy.
- Select Manage how people find you on Skype.
- Toggle Appear in search results and suggestions off. You can make yourself discoverable again by toggling this option back on at any time.
