You can make your entire Deezer Profile private so that it is not visible to other users. Nobody will be able to see your music feed or your music library.
- Log in to your Deezer account via Deezer.com
- Click on the Settings icon
- Click Account Settings
- Tap the Alerts and Sharing tab
- Under the I would like heading, will be a chance to tick Make my profile private
You can change this back whenever you want by following the same process.
