1. Processing of personal data within the digital presences

1.1 Collection and processing of personal data on websites

- the web pages you visit on our site

- the website that you visit from our websites
- the access status (e.g. an error message)
- the current time (date and time) of the visit
- any search terms you may have entered

- the IP address assigned by your Internet provider. We store this data for a period of seven days to prevent and detect attacks.

We store and process other personal data only if you provide it to us, for example, for registration, within a contact form, or for the performance of a contract. The storage and processing is always carried out in accordance with applicable legal regulations or on the basis of a granted consent.

1.2 Use of personal data

massup uses your data when you visit our websites

- for the presentation and delivery of our contents

- for statistical purposes

- to provide and improve our offer

- for technical administration of the website

- to protect against attacks on our IT systems

This is done only to the extent necessary in each case.

massup uses the data you provide us for registration, within a contact form, or for the execution of a contract for the purposes mentioned above, as well as

- for customer administration

- for product surveys and marketing if you have given your consent

- processing and billing of contracts

This is done only to the extent necessary in each case.

1.3 Deletion of your personal data

Your personal data will be deleted as soon as the purpose for which we collected and processed the data no longer applies. Beyond this point in time, data will only be stored if this is required by valid legal regulations of the European Union or the Federal Republic of Germany. In addition, we process personal data for purposes of safeguarding our legitimate interests as well as the legitimate interests of third parties in accordance with Art.6 para. 1f DSGVO.

1.4 Social plug-ins and transfer of personal data to third parties
We use so-called „social plug-ins“ from social networks such as Google+ or Facebook on our websites. These are integrated as follows:

When you access our websites, the „social plug-ins“ are deactivated, i.e. there is no transmission of data to the operators of these social networks. If you wish to use one of the social networks, click on the corresponding „Social PlugIn“ to activate it and a connection will be established with the server of the respective social network. If you are logged in to the social network at the moment of activating the „Social PlugIn“, the social network can assign your visit to our websites to your user account there. Then the social network transmits content directly to your browser, which integrates it into our websites. At this moment, data may also be transmitted that is initiated and controlled by the respective social network. Please bear in mind that this may involve personal data being transferred to countries outside the European Economic Area that do not ensure an „adequate level of protection“ from the perspective of the European Union. If you log out of the social network before activating the „Social PlugIn“, the social network cannot assign your visit to our websites. An activated „Social PlugIn“ remains active until you deactivate it or delete your cookies.

Cookie notices

For all connection from your device to the social network, the privacy policy of the corresponding social network applies exclusively.
