Data protection on Facebook: 10 tips on how you can protect your personal data


But with the increasing mass of personal data, criticism of the data protection of the contact platform is also increasing, not least in connection with security deficiencies. Only recently did Facebook respond to criticism and simplify the security of personal data. For most users, backing up personal information, and some information that is not intended for the general public, is still quite opaque and complicated. This article will help you protect your data on Facebook.

1. Invisibility of the profile for Facebook and Google searches

So that your profile is no longer listed in a Google search, you can switch this off in the "Privacy" under the heading "Applications and websites". If you do not want to be found by other Facebook users, you should deselect your visibility in the general search under “Privacy” under “Search”.

2. What data do I reveal?

Check at regular intervals what information you provide on your profile and reflect on whether this is really necessary. In this context, pay attention to which friends list can see which information.

3. User ID

Every Facebook user has an individual user ID. Knowledge of this ID does not allow access to private information, but some information is categorized as “publicly accessible” by Facebook. The name, profile picture and connections are generally available data that can be accessed by anyone on the Internet.

Using the user ID, it is still possible to find out the associated name, so that every member should assume that his name, his contacts and his profile picture are freely accessible.

4. Business use of Facebook

The personal profile can be used not only for private, but also for business purposes. If you do not want to share all of the information that you reveal to your friends with your business contacts, you should organize your contacts in friend lists. In this way you can determine which friends list you want to display.

5. Friendships

With every friend request, pay attention to who you are confirming as a friend. Because a potential friend is not always interested in you. Rather, he might want your data. So make a conscious decision who you want to take as a friend and which data should be visible for the contact.

If you want to avoid that anyone can click through your friendships, define the accessibility of your contacts in the "General Information" under "Privacy".

6. Keep contact information private

The personal contact information can be kept private, for example if the private cell phone number should not be accessible to business contacts. This can be changed in the "Privacy" under "Custom Settings".

7. Photo album visibility

Photo albums don't necessarily have to be visible to every friend. If, for example, the vacation photos are not to be viewed by the business contacts, you can change this in the "Privacy" settings in the "Photos" section. If you select the setting "User-defined" there, you can select the corresponding list of friends for whom the photo albums should be visible.

8. "News and pin board"

In this category you can define which changes in the private settings (e.g. relationship status, interests, place of residence, etc ...) should be made visible to your friends. For example, you can deselect the item "Change relationship status" and thus make it appear less interesting.

9. Use of Applications

In particular, the use of applications (or "apps") that have been developed by third parties pose a great risk to personal data. User IDs from these applications are said to have been passed on to advertisers or address collectors. However, Facebook users can also protect themselves from such data transfers by using as few applications as possible. "Privacy" also provides an overview of the third-party applications that you use under the heading ("Applications and websites").

10. Communication via Facebook

Dialogues on the pin board are public and can be read by all contacts. So if you would like to send a private message to a friend, use the option of sending a message on the contact's profile via "Send a message".


Regularly check the options Facebook offers to protect your personal information. Keep the information that is private, too. Use your "privacy" settings to ensure that the data remains private. Also, think carefully about who you add as a friend and thus offer free access to your data.
