The contact data entered on your profile page is not visible to other members by default (exception: city, state and country from the business contact data). As the profile owner, however, you always see your contact data without restriction.
This is how you proceed:
- Log in to XING with your XING data.
- Click on your small profile photo in the top left navigation and select "Settings".
- Now click on "Privacy".
- Select "Contact details". Now you can select for whom your business and private contact data, as well as your date of birth, are visible.
- In addition, you have the option to "Add exceptions".
