Personal data is information that discloses or may disclose the identity of the user. We adhere to the principle of data avoidance. As far as possible, we try to deliver our services without the collection of personal data.

1.2 Handling of personal data

Personal data are used exclusively for establishing the contract, arrangement, alteration or execution of the contractual relationship (Art. 6 I b GDPR). They are not passed on to third parties. In order to process payments, the necessary payment data will be forwarded to the credit institution commissioned with the payment and, if applicable, to the commissioned and chosen payment service provider. Your personal data will be processed exclusively within the EU, with the exception of our push message feature for iOS and Android devices (unless it is set to "anonymous").

1.3 Data access

By using the app we can, depending on which functions you want to use specifically, get access to the following types of data:

  • Device
  • Device type
  • Time zone
  • Country of origin
  • Photos / Media / Files / Data

If you do not want this, please do not use these functions.

1.4 Usage data

When visiting the website / app general technical information is collected. These are the used IP address, time, duration of the visit, and by visiting our website the browser type and the origin site as well as by using the app the device type. These usage data are registered in a logfile for technical reasons and can be used and stored for statistical purposes of this website / app. A linking of this usage data with your other personal data does not take place.

1.5 Registration data

To fully utilize the features of our website / app, a registration is required. The registration data are collected through your input and used for the purpose specified in accordance with your consent (Art. 6 I a GDPR).

1.6 Duration of storage

We store your personal data after the end of the purpose for which the data was collected, only as long as required by law (in particular tax law).

2. Your rights

2.1 Information

You can ask us for information about whether we process personal data of you and, as far as this is the case, you have the right to request information about these personal data and to the other information mentioned in Art. 15 GDPR.

2.2 Right to rectification

You have the right to order a correction of incorrect personal data relating to you and may request the completion of incomplete personal data in accordance with Art. 16 GDPR.

2.3 Right to delete

You have the right to demand that the personal data concerning you be deleted immediately. We are obliged to delete them immediately, especially if one of the following reasons applies:

  • Your personal data is no longer necessary for the purposes for which it was collected or otherwise processed.
  • You revoke your consent to the processing of your data and there is no other legal basis for processing them.
  • Your data was processed unlawfully.

The right to delete does not exist if your personal data is necessary for the assertion, exercise or defense of our legal rights.

2.4 Right to restriction of processing

You have the right to require us to restrict the processing of your personal data if

  • you deny the accuracy of the data and we therefore check the accuracy,
  • the processing is unlawful and you refuse the deletion and instead demand the restriction of use,
  • we no longer need the data, but you need it to assert, exercise or defend your rights,
  • you have expressed an objection to the processing of your data, and it is not yet clear whether our legitimate reasons outweigh your reasons.
2.5 Right to data portability

You have the right to receive the personal information that you have provided us in a structured, common and machine-readable format and you have the right to transfer this data to another person without hindrance from us, provided the processing is based on your consent or a contract and processing is done by us using automated procedures.

2.6 Right of withdrawal

As far as the processing of your personal data is based on a consent, you have the right to revoke this consent at any time.

2.7 General and right to complain

The exercise of your rights stated above is free of charge. You have the right to contact the responsible supervisory authority, the state data protection officer, directly in case of complaints.

3. Data security

3.1 Data security

All data on our website / app are protected against loss, destruction, access, modification and dissemination through technical and organizational measures. However, we assume no liability for the destruction and damage of data.

3.2 Sessions and Cookies

To operate the website, we may use cookies or server-side sessions in which data can be stored. Cookies are files that are stored on your hard drive by a web page in order to automatically recognize this computer the next time you visit a website and to adapt the use of the website to you.

Some of the cookies used will be deleted after the end of the browser session. These are so-called session cookies. Other cookies remain on your device and allow the recognition of the browser during a later visit to our website (persistent cookies).

Likewise, persistent cookies are used for marketing purposes - for example, to define an original source of a user - whereby the setting and evaluation of these cookies is done exclusively by Stackfield itself. These cookies are stored for 90 days on the user's device. No interests of the users are affected, which could outweigh the registration of the source of the user (Art. 6 I S. 1 f GDPR). An opt-out, i.e. deactivation, of this kind of cookies for marketing purposes, is possible by clicking on the following link: Deactivate Tracking Cookies

Please note that even if the marketing cookies are deactivated, cookies will still be used to operate the website.

You can set your browser so that you are informed about the setting of cookies and individually decide on their acceptance or exclude the acceptance of cookies for specific cases or in general. Please note that you may not be able to use some features of this website if cookies are disabled.

We make sure that no personal data is taken over from sessions or through cookies and that cookies are only used if this is necessary for the website. Thus, the consideration shows that there are no overriding interests against you (Art. 6 I f GDPR).

4. Newsletter

If you subscribe to our newsletter, we will use the information required or separately provided by you to send you regular e-mail newsletters. The deregistration from the newsletter is possible at any time and can be done either by a message to us via the contact options specified in the imprint or via the dedicated link in the newsletter.

5. Push-Notifications

If you are using Stackfield on your mobile device, your device will be registered with the corresponding push service of the platform you are using (iOS - Apple Push Notification Service, Android - Google Cloud Messaging). In this case, your registration ID (Android) or your token (iOS) assigned by this registration will be sent to and stored by the respective service and our platform. The respective service providers have complied with the requirements of the EU-US Privacy Shield.

We use the push message feature to inform you about relevant information on your device without having to open our app for it. You can deactivate or anonymize (if not already preset) the push message function at any time in the settings of the organization. In addition, we'd like to inform you that third-party providers (Google and Apple) can not monitor or review the push notifications, and therefore do not act as the data processor for this service.

6. Präsenz auf Social Media Plattformen

We use the following social media platforms for company presentation and communication (the following linked privacy statements and opt-out options are expressly referred to).

These social media platforms may be able to process personal data outside the EU. We refer to the privacy statements of the social media platforms. Depending on your usage behavior and the resulting interests, the respective social media platforms may create user profiles for us and save cookies on your computer in which your usage behavior is stored. If you have an account on the respective social media platform and are logged in, your usage behavior can even be stored device-independently. Their usage profile can be used to e.g. place advertisements that are allegedly in line with your interests.

We process the personal data exclusively for communication with you about the social media platform chosen by you as well as the optimization of ours and ensure that no interests of yours are affected which outweigh this legitimate interest on our part (Art. 6 I p. 1 f GDPR). Insofar as you have already given the respective operator of the social media platform an effective consent to the relevant data processing, the processing of your personal data is also based on this consent (Article 6 I p. 1 a GDPR).

7. Third party services

Your personal information will be transferred to the third-party providers listed below only after you manually activate it yourself. When you use YouTube, we are using the advanced privacy options to prevent YouTube from setting cookies for tracking and promotional purposes.

7.1 Social media links and social sharing

We have separate social media sites on third-party sites to be reached through links from this website / app. By using the links you can access the respective websites of the third party providers (for example Facebook, Twitter, Google+) and you can also share our contents. Once you have accessed the third-party site, you are in the area of responsibility of each third-party provider, including their privacy statements and their statements about your use of the data. We have no influence on this, but we recommend to avoid unnecessary data transfer before using a corresponding link by logging out yourself from the respective third party, so by the use of the link no tracking like creating user profiles can be created by the third party.

7.2 Use of YouTube

This website and the integrated services contain so-called embedding of videos on YouTube. These allow the connection to YouTube and the videos stored there. YouTube is an offer from Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Irland (“Google”). For the purpose and scope of Google's data collection and use, as well as your rights and preferences for protection as a customer of YouTube, please visit the YouTube Privacy Policy. These can be found at:

7.3 Using the comment function of DISQUS

We also use the comment function of DISQUS (operated by DISQUS, Inc., 301 Howard St., Suite 300, San Francisco, CA 94105, USA). DISQUS allows you to log in either through your own DISQUS account or via your Facebook, Twitter or Google Plus account. For registration via the named social media services, the privacy policy and terms of use of these services apply:

When registering using these services, information about your use of the DISQUS functions will also be collected and processed by these providers.

In addition to the named functions, you can also comment on a limited basis as a guest. Your IP address and e-mail address provided when leaving a comment will be sent to us by DISQUS. We need this information for the purpose of contacting you in connection with your use of DISQUS (for example, in response to your comments).

7.4 Inxmail

For the mailing of any mails (autoresponder, system emails, etc.) an interface to our contractor Inxmail (Inxmail GmbH, Wentzingerstr. 17, 79106 Freiburg, Deutschland) is used. Only your mail address will be transferred to Inxmail and saved. In addition, Inxmail may, for its own information, use this data to optimize or improve its own services, e.g. for the technical optimization of the dispatch and the presentation of the mails. Inxmail does not use the data of our e-mail recipients to send marketing emails themselves or to pass them on to third parties. Thus, the consideration shows that there are no overriding interests on your part (Art. 6 I p. 1 f GDPR). To use the service, the terms of Inxmail apply:

8. Downloading information material

In the course of downloading information material, such as white papers, your contact details (first name, last name, company name, business e-mail address) are collected. By confirming the privacy policy and downloading this content, you agree to be contacted by our sales team and to receive offers and further marketing content. The legal basis for processing your personal data in this context is Article 6(1)(a) GDPR.
