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:
- In the Chats screen, tap your profile picture.
- Tap the settings button.
- Tap Privacy, and then tap Include me in search and suggestions.
You can make yourself discoverable again by turning this option back on at any time.
