This agreement stipulates that LinkedIn itself assumes all data protection obligations in connection with Page Insights.

2.   Categories of Data, purpose and legal basis

With regard to the data processing by LinkedIn we refer to its data protection notice:

Below we explain the data processing operations we carry out.

a)   Statistical Data

We can retrieve statistical data of different categories via the so-called “Insights” (
These statistics are created and provided by LinkedIn. LinkedIn provides us with the following data for a definable period of time for the categories, respectively, job title, company and industry: Number of interactions like Likes, comments, shared posts, clicks, shares, conversion rate, video views of posts on our LinkedIn site.
As a result of the continuous development of LinkedIn, the availability and processing of data changes, wherefore we refer to the data protection notice of LinkedIn for more detailed information.
Legal basis for processing is Art. 6 1 f GDPR. Making our posts and activities more attractive to users is our legitimate interest. For example, we use demographic data for addressing our users in an adjusted way and the preferred visiting hours of the users for optimized scheduling of our posts. Information about the user’s device help us adjusting our posts in appearance.

b)   Interactions with our account

Also, you can interact with our account. For example, you can do that by pressing the “Like” button, sharing or commenting on a post or by directly writing to us.
In case of you interacting with us, we inevitably process your data as we then can see your account and therefore have access to your personal data; this includes your username, profile picture or date or time of your interaction. According to LinkedIn’s terms of use, that every user has agreed to when creating a LinkedIn profile, we can identify subscribers and fans of the page and view their profile as well as their shared content.
These data are information that are only provided through an interaction with our profile. Legal basis for processing is Art. 6 1 b GDPR.

 3.   Recipient of data

We would like to point out that LinkedIn might transmit your data to third parties. We cannot influence this, though. You can find more detailed information within the data protection notice of LinkedIn:

We only share personal data within our organization if and when necessary for the purposes specified in this privacy notice. We don´t share personal data with any third party outside of our organization unless one of the following circumstances applies.

Art 6 (1) c GDPR

Processing is necessary for compliance with a legal obligation to which the controller is subject.
Recipients of your personal data may be public offices as well as processors, processing the data collected online in our behalf (Webhosts, designer etc.)

 4.   Storage period and erasure

You can find information about data storage by LinkedIn in their data protection notice:

We store the personal data transmitted to us by you only for the period of time that is necessary to fulfil the purposes for which the data have been transmitted or as long as we are obligated by law to store them. After fulfilment of the purpose and/or after the legal retention period has expired, we either delete or block the data.

5.   Your rights

According to GDPR you have the following rights with regard to your personal data. You can find more detailed information in Art. 15 to 21 GDPR as well as in §§ 32 to 37 German Federal Data Protection Act. 
You have the right to access your personal data. You may also request the rectification of inaccurate data. Under certain conditions you have the right to erasure, the right to restriction and the right to data portability. Further, you have the right to object to processing of personal data which is based on point (e), (f) of Art. 6(1), including profiling based on those provisions. You may withdraw your consent at any time and without giving reasons with effect for the future. 

You may assert these rights directly with the controller. Therefore, informal contact is sufficient. You may send an Email or a letter. 
You also have the right to lodge a complaint with a supervisory authority if you find our processing of your personal data to be inconsistent with applicable data protection law. A list of federal Data Protection Commissioner and contact data can be found here:
