3. general notes and mandatory information data protection

The operators of these pages take the protection of your personal data very seriously. We treat your personal data confidentially and in accordance with the statutory data protection regulations and this privacy policy.

When you use this website, various personal data are collected. Personal data is data with which you can be personally identified. This privacy policy explains what data we collect and what we use it for. It also explains how and for what purpose this is done.

We point out that data transmission over the Internet (eg communication by e-mail) security gaps. A complete protection of the data against access by third parties is not possible.

Note on the responsible entity

The responsible party for data processing on this website is:

Mathefritz Media Jörg Christmann Pfaffenkopfstr. 21E 66125 Saarbrücken, Germany

Phone: +49 (0) 68 97 - 500 9490 E-mail: [email protected]

The controller is the natural or legal person who alone or jointly with others determines the purposes and means of the processing of personal data (e.g. names, e-mail addresses, etc.).

Storage duration

Unless a more specific storage period has been specified within this privacy policy, your personal data will remain with us until the purpose for data processing no longer applies. If you assert a legitimate request for deletion or revoke your consent to data processing, your data will be deleted unless we have other legally permissible reasons for storing your personal data (e.g. retention periods under tax or commercial law); in the latter case, the data will be deleted once these reasons no longer apply.

General information on the legal basis for data processing on this website

If you have consented to data processing, we process your personal data on the basis of Art. 6 (1) a DSGVO or Art. 9 (2) a DSGVO, if special categories of data are processed according to Art. 9 (1) DSGVO. In the case of explicit consent to the transfer of personal data to third countries, the data processing is also based on Art. 49 (1) a DSGVO. If you have consented to the storage of cookies or to the access to information in your terminal device (e.g. via device fingerprinting), the data processing is additionally carried out on the basis of Section 25 (1) TTDSG. The consent can be revoked at any time. If your data is required for the performance of a contract or for the implementation of pre-contractual measures, we process your data on the basis of Art. 6 para. 1 lit. b DSGVO. Furthermore, if your data is required for the fulfillment of a legal obligation, we process it on the basis of Art. 6 para. 1 lit. c DSGVO. Furthermore, the data processing may be carried out on the basis of our legitimate interest according to Art. 6 para. 1 lit. f DSGVO. Information about the relevant legal basis in each individual case is provided in the following paragraphs of this privacy policy.

Note on data transfer to the USA and other third countries

Among other things, we use tools from companies based in the USA or other third countries that are not secure under data protection law. If these tools are active, your personal data may be transferred to these third countries and processed there. We would like to point out that no level of data protection comparable to that in the EU can be guaranteed in these countries. For example, US companies are obliged to hand over personal data to security authorities without you as a data subject being able to take legal action against this. It can therefore not be ruled out that US authorities (e.g. intelligence services) process, evaluate and permanently store your data located on US servers for monitoring purposes. We have no influence on these processing activities.

Recipients of personal data

In the course of our business activities, we cooperate with various external bodies. In some cases, this also requires the transfer of personal data to these external bodies. We only pass on personal data to external bodies if this is necessary within the framework of the performance of a contract, if we are legally obliged to do so (e.g. passing on data to tax authorities), if we have a legitimate interest in passing on the data in accordance with Art. 6 Para. 1 lit. f DSGVO or if another legal basis permits the passing on of the data. When using processors, we only disclose personal data of our customers on the basis of a valid contract on commissioned processing. In the case of joint processing, a joint processing agreement is concluded.

Revocation of your consent to data processing

Many data processing operations are only possible with your express consent. You can revoke consent you have already given at any time. The legality of the data processing carried out until the revocation remains unaffected by the revocation.

Right to object to data collection in special cases and to direct marketing (Art. 21 DSGVO)

IF THE DATA PROCESSING IS CARRIED OUT ON THE BASIS OF ART. 6 ABS. 1 LIT. E OR F DSGVO, YOU HAVE THE RIGHT TO OBJECT TO THE PROCESSING OF YOUR PERSONAL DATA AT ANY TIME FOR REASONS ARISING FROM YOUR PARTICULAR SITUATION; THIS ALSO APPLIES TO PROFILING BASED ON THESE PROVISIONS. THE RESPECTIVE LEGAL BASIS ON WHICH PROCESSING IS BASED CAN BE FOUND IN THIS PRIVACY POLICY. IF YOU OBJECT, WE WILL NO LONGER PROCESS YOUR PERSONAL DATA UNLESS WE CAN DEMONSTRATE COMPELLING LEGITIMATE GROUNDS FOR THE PROCESSING WHICH OVERRIDE YOUR INTERESTS, RIGHTS AND FREEDOMS, OR THE PROCESSING SERVES THE PURPOSE OF ASSERTING, EXERCISING OR DEFENDING LEGAL CLAIMS (OBJECTION UNDER ARTICLE 21 (1) DSGVO).

IF YOUR PERSONAL DATA IS PROCESSED FOR THE PURPOSE OF DIRECT MARKETING, YOU HAVE THE RIGHT TO OBJECT AT ANY TIME TO THE PROCESSING OF PERSONAL DATA CONCERNING YOU FOR THE PURPOSE OF SUCH MARKETING; THIS ALSO APPLIES TO PROFILING INSOFAR AS IT IS CONNECTED WITH SUCH DIRECT MARKETING. IF YOU OBJECT, YOUR PERSONAL DATA WILL SUBSEQUENTLY NO LONGER BE USED FOR THE PURPOSE OF DIRECT MARKETING (OBJECTION PURSUANT TO ARTICLE 21 (2) DSGVO).

Right of appeal to the competent supervisory authority

In the event of breaches of the GDPR, data subjects shall have a right of appeal to a supervisory authority, in particular in the Member State of their habitual residence, their place of work or the place of the alleged breach. The right of appeal is without prejudice to other administrative or judicial remedies.

Right to data portability

You have the right to have data that we process automatically on the basis of your consent or in fulfillment of a contract handed over to you or to a third party in a common, machine-readable format. If you request the direct transfer of the data to another controller, this will only be done insofar as it is technically feasible.

Information, correction and deletion

Within the framework of the applicable legal provisions, you have the right at any time to free information about your stored personal data, its origin and recipient and the purpose of data processing and, if necessary, a right to correction or deletion of this data. For this purpose, as well as for further questions on the subject of personal data, you can contact us at any time.

Right to restriction of processing

You have the right to request the restriction of the processing of your personal data. For this purpose, you can contact us at any time. The right to restriction of processing exists in the following cases:

If you dispute the accuracy of your personal data stored by us, we usually need time to verify this. For the duration of the verification, you have the right to request the restriction of the processing of your personal data.
If the processing of your personal data happened/is happening unlawfully, you can request the restriction of the data processing instead of the deletion.

If we no longer need your personal data, but you need it to exercise, defend or enforce legal claims, you have the right to request restriction of the processing of your personal data instead of deletion.
If you have lodged an objection in accordance with Art. 21 (1) DSGVO, a balance must be struck between your interests and ours. As long as it has not yet been determined whose interests prevail, you have the right to request the restriction of the processing of your personal data.

If you have restricted the processing of your personal data, this data may - apart from being stored - only be processed with your consent or for the assertion, exercise or defense of legal claims or for the protection of the rights of another natural or legal person or for reasons of an important public interest of the European Union or a Member State.

SSL or TLS encryption

For security reasons and to protect the transmission of confidential content, such as orders or requests that you send to us as the site operator, this site uses SSL or TLS encryption. You can recognize an encrypted connection by the fact that the address line of the browser changes from "http://" to "https://" and by the lock symbol in your browser line.

If SSL or TLS encryption is activated, the data you transmit to us cannot be read by third parties.

Objection to advertising e-mails

The use of contact data published within the framework of the imprint obligation to send advertising and information materials not expressly requested is hereby prohibited. The operators of the pages expressly reserve the right to take legal action in the event of the unsolicited sending of advertising information, such as spam e-mails.

The website operator has a legitimate interest in storing necessary cookies for the technically error-free and optimized provision of its services. If consent to the storage of cookies and comparable recognition technologies has been requested, the processing is based exclusively on this consent (Art. 6 para. 1 lit. a DSGVO and § 25 para. 1 TTDSG); the consent can be revoked at any time.

5. analysis tools and advertising - Google Analytics

This website uses functions of the web analytics service Google Analytics. The provider is Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.

Google Analytics enables the website operator to analyze the behavior of website visitors. In doing so, the website operator receives various usage data, such as page views, dwell time, operating systems used and the origin of the user. This data is assigned to the respective end device of the user. An assignment to a user ID does not take place.

Furthermore, Google Analytics allows us to record your mouse and scroll movements and clicks, among other things. Furthermore, Google Analytics uses various modeling approaches to supplement the collected data sets and uses machine learning technologies in the data analysis.

Google Analytics uses technologies that enable the recognition of the user for the purpose of analyzing user behavior (e.g. cookies or device fingerprinting). The information collected by Google about the use of this website is usually transferred to a Google server in the USA and stored there.

The use of this service is based on your consent according to Art. 6 para. 1 lit. a DSGVO and § 25 para. 1 TTDSG. The consent can be revoked at any time.

Data transfer to the USA is based on the standard contractual clauses of the EU Commission. Details can be found here:

For more information on how Google Analytics handles user data, please see Google's privacy policy:https://support.google.com/analytics/answer/6004245?hl=de.

Google AdSense (not personalized)

This website uses Google AdSense, a service for integrating advertisements. The provider is Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.

We use Google AdSense in "non-personalized" mode. In contrast to the personalized mode, the advertisements are therefore not based on your previous user behavior and no user profile of you is created. Instead, so-called "contextual information" is used to select the advertisements. The selected ads are then based, for example, on your location, the content of the website you are on, or your current search terms. You can find out more about the differences between personalized and non-personalized targeting with Google AdSense at:

https://support.google.com/adsense/answer/9007336.

Please note that cookies or comparable recognition technologies (e.g. device fingerprinting) may also be used when using Google Adsense in non-personalized mode. According to Google, these are used to combat fraud and abuse.

The use of this service is based on your consent according to Art. 6 para. 1 lit. a DSGVO and § 25 para. 1 TTDSG. The consent can be revoked at any time.

Data transfer to the USA is based on the standard contractual clauses of the EU Commission. Details can be found here:

More information about Google's advertising technologies can be found here: https://policies.google.com/technologies/ads and https://www.google.de/intl/de/policies/privacy/.

6. newsletter - newsletter data

If you would like to receive the newsletter offered on the website, we require an e-mail address from you as well as information that allows us to verify that you are the owner of the specified e-mail address and agree to receive the newsletter. Further data is not collected or only on a voluntary basis. We use this data exclusively for sending the requested information and do not pass it on to third parties.

The processing of the data entered in the newsletter registration form is based exclusively on your consent (Art. 6 para. 1 lit. a DSGVO). You can revoke your consent to the storage of the data, the e-mail address and their use for sending the newsletter at any time, for example via the "unsubscribe" link in the newsletter. The legality of the data processing operations already carried out remains unaffected by the revocation.

The data you provide for the purpose of receiving the newsletter will be stored by us or the newsletter service provider until you unsubscribe from the newsletter and will be deleted from the newsletter distribution list after you unsubscribe from the newsletter or after the purpose has ceased to exist. We reserve the right to delete or block e-mail addresses from our newsletter distribution list at our own discretion within the scope of our legitimate interest pursuant to Art. 6 (1) lit. f DSGVO.

Data that has been stored by us for other purposes remains unaffected by this.

After you have unsubscribed from the newsletter distribution list, your e-mail address will be stored by us or the newsletter service provider in a blacklist, if necessary, to prevent future mailings. The data from the blacklist will only be used for this purpose and will not be merged with other data. This serves both your interest and our interest in complying with legal requirements when sending newsletters (legitimate interest within the meaning of Art. 6 (1) lit. f DSGVO). The storage in the blacklist is not limited in time. You can object to the storage if your interests outweigh our legitimate interest.

7. plugins and tools
YouTube with enhanced data protection

This website embeds videos from the website YouTube. The operator of the pages is Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.

We use YouTube in extended privacy mode. According to YouTube, this mode means that YouTube does not store any information about visitors to this website before they watch the video. However, the disclosure of data to YouTube partners is not necessarily excluded by the extended data protection mode. Thus, YouTube - regardless of whether you watch a video - establishes a connection to the Google DoubleClick network.

As soon as you start a YouTube video on this website, a connection to the YouTube servers is established. This tells the YouTube server which of our pages you have visited. If you are logged into your YouTube account, you enable YouTube to assign your surfing behavior directly to your personal profile. You can prevent this by logging out of your YouTube account.

Furthermore, after starting a video, YouTube may store various cookies on your end device or use comparable recognition technologies (e.g. device fingerprinting). In this way, YouTube can obtain information about visitors to this website. This information is used, among other things, to collect video statistics, improve the user experience, and prevent fraud attempts.

If necessary, further data processing operations may be triggered after the start of a YouTube video, over which we have no control.

YouTube is used in the interest of an appealing presentation of our online offers. This represents a legitimate interest within the meaning of Art. 6 para. 1 lit. f DSGVO. Insofar as a corresponding consent has been requested, the processing is carried out exclusively on the basis of Art. 6 para. 1 lit. a DSGVO and § 25 para. 1 TTDSG, insofar as the consent includes the storage of cookies or access to information in the user's terminal device (e.g. device fingerprinting) within the meaning of the TTDSG. The consent can be revoked at any time.

For more information about privacy at YouTube, please see their privacy policy at: https://policies.google.com/privacy?hl=de.

Google Fonts (local hosting)

This site uses so-called Google Fonts, which are provided by Google, for the uniform display of fonts. The Google Fonts are installed locally. A connection to Google servers does not take place.

For more information about Google Fonts, please visit https://developers.google.com/fonts/faq and read Google's privacy policy:https://policies.google.com/privacy?hl=de.
