The original version of our Privacy Policy is in German. Foreign-language versions of this Policy like this version are intended for information purposes only. In the event of any ambiguity, inconsistency, conflict or contradiction between the German version and any translation thereof, the German version and its wording shall prevail.

The content of this website has been compiled with utmost care and is continually updated. However, despite meticulous control, we cannot guarantee full accuracy of all information included on this website. Legal liability on our behalf for lack of accuracy, completeness and timeliness of the information provided on this website is thus excluded.

Likewise, we shall assume no liability for any third-party contents linked to on our website through external links. Neither can we guarantee nor be held liable for the protection of your data and privacy on such third-party websites and venues.

That said, protecting your privacy in processing personal data as well as insuring the security of all business data is important to us. Any data collected during your visit to our website will be handled with utmost confidentiality and always in strict accordance with all pertinent legal provisions and regulations.

In the interest of maximum transparency, the following sections will detail whom to contact about privacy and data protection concerns as well as what information is gathered and how data are collected when you visit our website.

In addition, this Policy and Statement explain your choices about how we actually use information collected about you. This also includes how you can object to certain uses of that information. However, if you do not agree with this Policy, you may be unable to use our services or interact with any other aspect of our business.

2. Personal data collection and storage

This section subsequently describes different ways we collect data, how such data are used, as well as for what purposes and to what ends such data are stored. 

a) Website

When calling up our website at, the Web browser you use on your terminal device automatically starts sending certain data and information to the web server on which our website runs. This happens for technical reasons as otherwise communication between the terminal device and the web server would be impossible. These data are temporarily stored in what is referred to as a “log file.” Specifically, the following information is automatically stored until auto-deleted: 

  • the IP address of the computer connecting to the website,
  • date and time of access,
  • name and URL of retrieved file(s),
  • address of the website where a person clicked a link that sent them to our website (referrer URL),
  • the Web browser used to contact our web server, and possibly
  • the operating system run on the terminal device as well as the name of your Internet Access Provider (IAP).

 The data listed above are processed by us exclusively: 

  • to guarantee smooth connection to our website,
  • to ensure easy and convenient use of our website,
  • to assess system security and stability, as well as
  • for further administrative purposes.



Such legitimate commercial interest in data processing has its legal basis in Article 6 Section 1, specifically Subsection f, of the European Union’s General Data Protection Regulation of 2016 (hereinafter referred to simply as “GDPR”). 

b) Contact form

As a quick means of getting in touch with us directly, either to have a question answered or to launch a request with our sales team, an online contact form is available on our website at

Anybody using the contact form needs to enter their name and provide a valid e-mail address so that we know who launched the inquiry and how to contact them to respond to their inquiry. Other entries may be made at the user’s discretion.  

All data for contacting purposes via the online form are processed, based on your voluntary consent, pursuant to GDPR Article 6 Section 1 Subsection a. Personal data collected from the contact form are automatically deleted once the question or inquiry has been answered or otherwise resolved. 

However, if the contact form is used to launch requests for quotations or directly for the purchase of our products or for the solicitation of our services, data processing ensues for the express purpose of commencement of contract negotiations pursuant to GDPR Article 6 Section 1 Subsection b. If and when such a contract is actually entered into, the respective data are stored for 10 years for tax and bookkeeping purposes, as mandated by German law.

c) Newsletter

To subscribe to our newsletter, you have to enter your e-mail address in the text field below the Newsletter heading on the navigation sidebar of our website. Then, you have to click the Submit link below the text field while the radio button to sign up is checked. Doing so constitutes consent as required by GDPR Article 6 Section 1 Subsection a.

In addition, though, we first double-check any such registration for subscription through a process called “double opt-in.” This means we will send you a confirmation link to the e-mail address you entered into the text field before submitting your request for registration. Only after clicking on this confirmation link will your registration be considered verified and will you start receiving our newsletter regularly.

Canceling your subscription is possible at any time. There are three options to do so: For one, you can go through the same steps on our website as described above but would need to have the radio button set to sign out while submitting your e-mail address. Alternatively, you can either click the corresponding link at the end of each newsletter or send us your cancellation by e-mail to

Your e-mail address will only be stored for the duration of your consent, after which it will be deleted.

d) Contract agreement with BIT

When you enter into a contract with us, we store your master data and, if necessary, any additional data required to implement and execute the contract. Pursuant to GDPR Article 6 Section 1 Subsection b, data processing may proceed for as long as it is required to meet and satisfy any contractual obligations, goals and purposes. This usually comprises the entire duration of the contractual relationship.

After execution of the contract has concluded and after statutory periods for retaining business records (e.g., those mandated by the German Commercial Code) have elapsed, your data are deleted in the absence of any legitimate interest for retention as outlined in GDPR Article 6 Section 1. 

3. Transfer of data

We shall not transfer your personal data to third parties under any circumstances other than the ones listed below. Specifically, we may share your personal data with third parties:

  • if you have given explicit consent for us to do so, as per GDPR Article 6 Section 1 Subsection a;
  • if, pursuant to GDPR Article 6 Section 1 Subsection f, disclosure of such data is required for the assertion, exercise, or defense of legal claims, and if there is no apparent reason to assume a legitimate interest in not having the data disclosed;
  • if transfer of data is required to comply with legal obligations, as laid out in GDPR Article 6 Section 1 Subsection c; or
  • if admissible by law and if, pursuant to GDPR Article 6 Section 1 Subsection b, necessary for establishing, processing and executing contractual relationships with you.



4. Rights of data subjects

You have the right:

  • to request information about personal data processed on you by us. As per GDPR Article 15, the scope of such inquiries may specifically include: the purpose(s) for processing said data in the first place; the categories of personal data collected; the recipients or categories of recipient the data has been or will be disclosed to; planned storage times; to what extent a right exists to insist on correction or deletion of data, to either impose restrictions on processing or to object to such processing per se; the right to lodge a formal complaint; the source if said data was not collected by us; and to what extent automated decision-making – such as profiling – is used, including meaningful information on such decision-making’s underlying logic;
  • to request immediate correction of inaccurate, incorrect or incomplete personal data stored by us, as per GDPR Article 16;
  • to request, pursuant to GDPR Article 17, deletion of stored data inasmuch as such data is not necessary for exercising the right to freedom of expression and information, for complying with legal obligations as outlined in Section 3 Subsection b, for reasons of public interest as described in Section 3 Subsection c, or for the assertion, exercise or defense of legal claims;
  • to request, pursuant to GDPR Article 18, that restrictions be placed on the processing of personal data if you are contesting the accuracy or veracity of said data. You may also do so if such processing is unlawful, but you do not want the data deleted while we have no further need for said data, because you need them for asserting, exercising, or defending legal claims, or if you have already objected against processing in accordance with GDPR Article 1 Section 1;
  • to receive personal data collected on you in a structured, commonly used and machine-readable format, pursuant to GDPR Article 20, or to exercise your right to data portability by requesting transmission of said data to a third party of your own choosing;
  • to revoke at any time consent to having us process your personal data as per GDPR Article 7 Section 3, which effectively bars us from continuing any data processing based on your initial consent in the future; as well as
  • to lodge a complaint with a supervisory authority pursuant to GDPR Article 77 Section 1. As a general rule, you would usually address such a complaint to a supervisory authority at your place of residence or work or, alternatively, at the location of our headquarters. 

5. Right to object

Pursuant to GDPR Article 21 Section 1, you shall have the right to object at any time to processing of your personal data based on legitimate interest, as outlined in GDPR Article 6 Section 1 Subsection f, on grounds relating to your particular situation. Pursuant to GDPR Article 21 Section 2, you may do the same in response to data processing for direct advertising or marketing purposes without the need to supply any further evidence of special circumstances applying to your own situation. Should you want to exercise your right to cancellation or objection, sending an e-mail message to is usually sufficient to do so.

6. Data protection and security

Throughout our website, we employ SSL (Secure Socket Layer), one of the most widespread communication protocols, in connection with data encryption at the highest grade supported by the browser you are using to connect to our website. These days, that typically means 256-bit encryption. Should your browser not support such encryption, 128.bit v3 technology is used instead. You can usually tell that an individual page on our website is transmitted in encrypted mode when a key or lock symbol is showing in locked state on the lower status bar of your browser.

What’s more, we always make certain to take organizational and technical safety measures in an attempt to ensure that your data are protected from incidental or intentional manipulation, partial or complete loss, destruction, or against unauthorized access by third parties. These measures are continuously upgraded and improved as available technology develops and evolves. 

7. Changes to the privacy statement 

This version of our privacy statement is in effect as of August 2019. Either as a result of developing our website and further expanding our selection or in response to new laws and regulations, we may change or update our privacy statement without prior notice. That said, you can always refer to the most recent version of our privacy statement and have it printed out on our website at

8. Cookies

We do use cookies on our site. Cookies are small data files your browser automatically creates and stores on your terminal device (like your laptop, tablet, or smartphone) when you visit our website. Such files neither harm your terminal device nor do they contain viruses, Trojans, or any other kind of malware. 

Cookies simply serve to log information resulting from or relating to contact between our website and the browser run on the respective terminal device. Please note that this per se does by no means enable us to immediately determine your identity. 

Instead, cookies are intended to help make navigating and using our webpages easier and more convenient for you. Session cookies, for instance, are used to recognize which individual pages you have already visited on our website during the current session. These are automatically deleted after leaving our website.

In addition, to improve usability further, we use temporary cookies that are stored on your device for a specific period of time. The next time you visit our website to take advantage of our services, it will automatically recognize that you have already visited before. It will also remember previous browser activity such as the input you performed during previous sessions as well as stateful information such as your settings. This way, you don’t have to readjust or re-enter your settings every time you visit our website. Cookies also serve to track and record how our website is used by visitors for the purpose of statistical analysis, which in turn allows us to find better ways of optimizing our online services and product portfolio. Again, these cookies allow us to automatically recognize that you are a repeat visitor to our website. They are automatically deleted after a predefined period of time. 

All data processed through the use of cookies for the aforementioned purposes are needed to safeguard our legitimate interests as well as those of third parties pursuant to GDPR Article 6 Section 1 Subsection f. 

By default, most browsers accept cookies automatically. However, you can configure your browser either so that no cookies are stored on your computer at all or so that there will be a prompt showing each time a new cookie is generated. Please keep in mind that disabling cookies altogether may mean that you cannot use all the features on our website.

9. Tracking-tools

Utilization of the tracking tools listed below is intended to help us design our website to best conform with both our customers’ and our own needs and preferences. In addition, it further serves to ensure that our website can be optimized quickly and continuously. We also use these measures to track and statistically record usage of our website so that we can analyze and evaluate these data for the purpose of optimizing the services we offer. 

These purposes do constitute a legitimate interest as outlined in GDPR Section 1 Subsection f. Please consult the following subsections to learn more about the respective purposes of data categories and processing tied to each respective tracking tool employed. 

a) Google Analytics

BIT’s website uses Google Analytics, a Web analysis service provided by Google LLC (hereinafter referred to as “Google”), headquartered at 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States of America, with its homepage available at do so in a continuous effort to keep optimizing our website seamlessly and to tailor it as closely as possible to our customers’ and our own needs. 

To this end, cookies are employed (as described under Section 8 above) and user profiles are created, each under a different pseudonym. Data on your use of our website tracked and generated by Google Analytic cookies includes: 

  • browser type and version,
  • operating-system type and version,
  • referrer URL (i.e., the address of the website where a person clicked a link that sent them to our website),
  • host name of the accessing terminal device (usually, its IP address), plus
  • time and date when the server inquiry was made.



This information is then sent to a Google server operating from the United States of America and subsequently stored there. Information collected in this fashion serves to analyze and evaluate usage data on our website as well as to collate and create website activity reports. It is also used to assist in providing supplementary services associated with website and Internet usage, especially as they pertain to facilitating market research and demand-oriented Web design. 

These data may be transmitted to third parties if so required by law or if said parties have been commissioned or contracted to process such data. However, under no circumstances is your IP address to be cross-referenced, combined, or merged with other data Google has collected. To safeguard this, IP addresses are to be anonymized, effectively obviating clear identification of an IP address with a specific entity or person.

You can disable automatic installation of cookies altogether by selecting the appropriate setting in your browser. Please note, though, that this may well prevent you from full use of all features available on our website. Alternatively, you can block Google from collecting and processing data relating to your use of our website (including your IP address) generated by the cookie by downloading and installing a browser add-on under As an alternative to installing the full browser add-on, especially when using mobile terminal devices, you can also click on this link to have an opt-out cookie set that will prevent any collection of data during all future visits to a specific website. This opt-out cookie is stored on your device, will only work with the browser you used when you activated it, and will affect data traffic on the website it was activated for only. If you delete your cookies in your browser, you will have to reset the opt-out cookie again as described above.

You can find more information on the issues of data protection and privacy, specifically as they relate to Google Analytics, by consulting the Google Analytics online help at


b) GoogleMaps

Google Maps, Google’s web-mapping service, is accessed through an application programming interface (API) on our website. This plug-in is integrated into our website by means of the so-called two-click method to protect visitors to our website in the most effective way possible. To use GoogleMaps’ features and functions, your IP address needs to be collected and stored. This information is sent to a Google server operating from the USA and stored there, usually without prior anonymization. 

We use Google Maps in an effort to guarantee appealing presentation and visualization of the services we offer online and to facilitate the process of easily locating the sites referenced on our website. This represents a legitimate interest as required by GDPR Article 6 Section 1 Subsection f. Responsibility to conform with all privacy-related laws and regulations (like the GDPR) rests with the respective provider of the service, in this case Google LLC. 

For more detailed information on how Google processes and safeguards your information, please refer to their privacy policy, as documented online at
