Data protection

The operators of this website and its pages take the protection of your personal data very seriously. Hence, we handle your personal data as confidential information and in compliance with the statutory data protection regulations and this Data Protection Declaration.

Whenever you use this website, a variety of personal information will be collected. Personal data comprises data that can be used to personally identify you. This Data Protection Declaration explains which data we collect as well as the purposes we use this data for. It also explains how, and for which purpose the information is collected.

We herewith advise you that the transmission of data via the Internet (i.e., through e-mail communications) may be prone to security gaps. It is not possible to completely protect data against third-party access.

Information about the responsible party (referred to as the “controller” in the GDPR)

The data processing controller on this website is:

OCS Optical Control Systems GmbH
Wullener Feld 24
58454 Witten
Germany

Phone: +49 2302 956 22 0
E-mail: info@ocsgmbh.com

The controller is the natural person or legal entity that single-handedly or jointly with others makes decisions as to the purposes of and resources for the processing of personal data (e.g., names, e-mail addresses, etc.).

Storage duration

Unless a more specific storage period has been specified in this privacy policy, your personal data will remain with us until the purpose for which it was collected no longer applies. If you assert a justified 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., tax or commercial law retention periods); in the latter case, the deletion will take place after these reasons cease to apply.

General information on the legal basis for the 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) GDPR or Art. 9 (2)(a) GDPR, if special categories of data are processed according to Art. 9 (1) DSGVO.

Information on data transfer to the USA and other non-EU countries

Among other things, we use tools of companies domiciled in the United States or other from a data protection perspective non-secure non-EU countries. If these tools are active, your personal data may potentially be transferred to these non-EU countries and may be processed there. We must point out that in these countries, a data protection level that is comparable to that in the EU cannot be guaranteed. For instance, U.S. enterprises are under a mandate to release personal data to the security agencies and you as the data subject do not have any litigation options to defend yourself in court. Hence, it cannot be ruled out that U.S. agencies (e.g., the Secret Service) may process, analyze, and permanently archive your personal data for surveillance purposes. We have no control over these processing activities.

Revocation of your consent to the processing of data

A wide range of data processing transactions are possible only subject to your express consent. You can also revoke at any time any consent you have already given us. This shall be without prejudice to the lawfulness of any data collection that occurred prior to your revocation.

Right to object to the collection of data in special cases; right to object to direct advertising (Art. 21 GDPR)

IN THE EVENT THAT DATA ARE PROCESSED ON THE BASIS OF ART. 6(1)(E) OR (F) GDPR, YOU HAVE THE RIGHT TO AT ANY TIME OBJECT TO THE PROCESSING OF YOUR PERSONAL DATA BASED ON GROUNDS ARISING FROM YOUR UNIQUE SITUATION. THIS ALSO APPLIES TO ANY PROFILING BASED ON THESE PROVISIONS. TO DETERMINE THE LEGAL BASIS, ON WHICH ANY PROCESSING OF DATA IS BASED, PLEASE CONSULT THIS DATA PROTECTION DECLARATION. IF YOU LOG AN OBJECTION, WE WILL NO LONGER PROCESS YOUR AFFECTED PERSONAL DATA, UNLESS WE ARE IN A POSITION TO PRESENT COMPELLING PROTECTION WORTHY GROUNDS FOR THE PROCESSING OF YOUR DATA, THAT OUTWEIGH YOUR INTERESTS, RIGHTS AND FREEDOMS OR IF THE PURPOSE OF THE PROCESSING IS THE CLAIMING, EXERCISING OR DEFENCE OF LEGAL ENTITLEMENTS (OBJECTION PURSUANT TO ART. 21(1) GDPR).

IF YOUR PERSONAL DATA IS BEING PROCESSED IN ORDER TO ENGAGE IN DIRECT ADVERTISING, YOU HAVE THE RIGHT TO OBJECT TO THE PROCESSING OF YOUR AFFECTED PERSONAL DATA FOR THE PURPOSES OF SUCH ADVERTISING AT ANY TIME. THIS ALSO APPLIES TO PROFILING TO THE EXTENT THAT IT IS AFFILIATED WITH SUCH DIRECT ADVERTISING. IF YOU OBJECT, YOUR PERSONAL DATA WILL SUBSEQUENTLY NO LONGER BE USED FOR DIRECT ADVERTISING PURPOSES (OBJECTION PURSUANT TO ART. 21(2) GDPR).

Right to log a complaint with the competent supervisory agency

In the event of violations of the GDPR, data subjects are entitled to log a complaint with a supervisory agency, in particular in the member state where they usually maintain their domicile, place of work or at the place where the alleged violation occurred. The right to log a complaint is in effect regardless of any other administrative or court proceedings available as legal recourses.

Right to data portability

You have the right to demand that we hand over any data we automatically process on the basis of your consent or in order to fulfil a contract be handed over to you or a third party in a commonly used, machine readable format. If you should demand the direct transfer of the data to another controller, this will be done only if it is technically feasible.

SSL and/or TLS encryption

For security reasons and to protect the transmission of confidential content, such as purchase orders or inquiries you submit to us as the website operator, this website uses either an SSL or a TLS encryption program. You can recognize an encrypted connection by checking whether the address line of the browser switches from “http://” to “https://” and also by the appearance of the lock icon in the browser line.

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

Information about, rectification and eradication of data

Within the scope of the applicable statutory provisions, you have the right to at any time demand information about your archived personal data, their source and recipients as well as the purpose of the processing of your data. You may also have a right to have your data rectified or eradicated. If you have questions about this subject matter or any other questions about personal data, please do not hesitate to contact us at any time.

Right to demand processing restrictions

You have the right to demand the imposition of restrictions as far as the processing of your personal data is concerned. To do so, you may contact us at any time. The right to demand restriction of processing applies in the following cases:

  • In the event that you should dispute the correctness of your data archived by us, we will usually need some time to verify this claim. During the time that this investigation is ongoing, you have the right to demand that we restrict the processing of your personal data.
  • If the processing of your personal data was/is conducted in an unlawful manner, you have the option to demand the restriction of the processing of your data in lieu of demanding the eradication of this data.
  • If we do not need your personal data any longer and you need it to exercise, defend or claim legal entitlements, you have the right to demand the restriction of the processing of your personal data instead of its eradication.
  • If you have raised an objection pursuant to Art. 21(1) GDPR, your rights and our rights will have to be weighed against each other. As long as it has not been determined whose interests prevail, you have the right to demand a restriction of the processing of your personal data.

If you have restricted the processing of your personal data, these data – with the exception of their archiving – may be processed only subject to your consent or to claim, exercise or defend legal entitlements or to protect the rights of other natural persons or legal entities or for important public interest reasons cited by the European Union or a member state of the EU.

Rejection of unsolicited e-mails

We herewith object to the use of contact information published in conjunction with the mandatory information to be provided in our Site Notice to send us promotional and information material that we have not expressly requested. The operators of this website and its pages reserve the express right to take legal action in the event of the unsolicited sending of promotional information, for instance via SPAM messages.

4. Recording of data on this website

Cookies

Our websites and pages use what the industry refers to as “cookies.” Cookies are small text files that do not cause any damage to your device. They are either stored temporarily for the duration of a session (session cookies) or they are permanently archived on your device (permanent cookies). Session cookies are automatically deleted once you terminate your visit. Permanent cookies remain archived on your device until you actively delete them, or they are automatically eradicated by your web browser.

In some cases, it is possible that third-party cookies are stored on your device once you enter our site (third-party cookies). These cookies enable you or us to take advantage of certain services offered by the third party (e.g., cookies for the processing of payment services).

Cookies have a variety of functions. Many cookies are technically essential since certain website functions would not work in the absence of the cookies (e.g., the shopping cart function or the display of videos). The purpose of other cookies may be the analysis of user patterns or the display of promotional messages.

Cookies, which are required for the performance of electronic communication transactions, or for the provision of certain functions you want to use (e.g., for the shopping cart function) or those that are necessary for the optimization (required cookies) of the website (e.g., cookies that provide measurable insights into the web audience), shall be stored on the basis of Art. 6(1)(f) GDPR, unless a different legal basis is cited. The operator of the website has a legitimate interest in the storage of required cookies to ensure the technically error free and optimized provision of the operator’s services. If your consent to the storage of the cookies and similar recognition technologies has been requested, processing occurs exclusively on the basis of the consent obtained (Art. 6(1)(a) GDPR and § 25 (1) TTDSG); this consent may be revoked at any time.

You have the option to set up your browser in such a manner that you will be notified any time cookies are placed and to permit the acceptance of cookies only in specific cases. You may also exclude the acceptance of cookies in certain cases or in general or activate the delete function for the automatic eradication of cookies when the browser closes. If cookies are deactivated, the functions of this website may be limited.

In the event that third-party cookies are used or if cookies are used for analytical purposes, we will separately notify you in conjunction with this Data Protection Policy and, if applicable, ask for your consent.

Server log files

The provider of this website and its pages automatically collects and stores information in so-called server log files, which your browser communicates to us automatically. The information comprises:

  • The type and version of browser used
  • The used operating system
  • Referrer URL
  • The hostname of the accessing computer
  • The time of the server inquiry
  • The IP address

This data is not merged with other data sources.

This data is recorded on the basis of Art. 6(1)(f) GDPR. The operator of the website has a legitimate interest in the technically error free depiction and the optimization of the operator’s website. In order to achieve this, server log files must be recorded.

Contact form

If you submit inquiries to us via our contact form, the information provided in the contact form as well as any contact information provided therein will be stored by us in order to handle your inquiry and in the event that we have further questions. We will not share this information without your consent.

The processing of these data is based on Art. 6(1)(b) GDPR, if your request is related to the execution of a contract or if it is necessary to carry out pre-contractual measures. In all other cases the processing is based on our legitimate interest in the effective processing of the requests addressed to us (Art. 6(1)(f) GDPR) or on your agreement (Art. 6(1)(a) GDPR) if this has been requested; the consent can be revoked at any time.

The information you have entered into the contact form shall remain with us until you ask us to eradicate the data, revoke your consent to the archiving of data or if the purpose for which the information is being archived no longer exists (e.g., after we have concluded our response to your inquiry). This shall be without prejudice to any mandatory legal provisions, in particular retention periods.

Request by e-mail, telephone, or fax

If you contact us by e-mail, telephone or fax, your request, including all resulting personal data (name, request) will be stored and processed by us for the purpose of processing your request. We do not pass these data on without your consent.

These data are processed on the basis of Art. 6(1)(b) GDPR if your inquiry is related to the fulfillment of a contract or is required for the performance of pre-contractual measures. In all other cases, the data are processed on the basis of our legitimate interest in the effective handling of inquiries submitted to us (Art. 6(1)(f) GDPR) or on the basis of your consent (Art. 6(1)(a) GDPR) if it has been obtained; the consent can be revoked at any time.

The data sent by you to us via contact requests remain with us until you request us to delete, revoke your consent to the storage or the purpose for the data storage lapses (e.g. after completion of your request). Mandatory statutory provisions – in particular statutory retention periods – remain unaffected.

Live chat Userlike

OCS GmbH uses chat software from the company <a href=”http://www.userlike.com/”>Userlike</a> UG (limited liability), Probsteigasse 44-46, 50670 Cologne, Germany. You can use the chat like a contact form to chat with our staff in almost real time. When you start the chat, the following personal data is collected:

– Date and time of the call,
– URL of the previously visited website,
– Amount of data sent.
– And if specified: First name, last name, and email address.

Depending on the course of the conversation with our employees, further personal data may be collected in the chat, which is entered by you. The nature of this data depends to a high extent on your enquiry or the problem you are describing to us. The purpose of processing all of this data is to provide you with a fast and efficient means of contacting us and thus to improve our customer service.

All our staff have been and will be trained on data protection and how to handle customer data safely and confidentially. All our employees are bound to confidentiality and have signed an addendum in their employee contracts to the obligation to maintain confidentiality and to observe data protection.

By accessing the website https://www.ocsgmbh.com, the chat widget is loaded in the form of a JavaScript file from AWS Cloudfront. The chat widget technically represents the source code that is executed on your computer and enables the chat.

OCS GmbH also saves the chat history. This serves the purpose of sparing you extensive explanations about the history of your enquiry under certain circumstances as well as for the constant quality control of our chat offer. The processing is therefore permitted in accordance with Art. 6 Para. 1 Letter f DSGVO. If you do not wish this, you are welcome to inform us of this using the contact details listed above. Stored chats will then be deleted by us immediately.

The storage of chat data also serves the purpose of ensuring the security of our information technology systems. At the same time, this is our legitimate interest, which is why the processing is permissible according to Art. 6 para. 1 letter f DSGVO.

For more information, please see the <a href=”http://www.userlike.com/terms#privacy-policy”>Data Protection Policy of Userlike</a> UG (limited liability).

5. Analysis tools and advertising

Matomo

This website uses the open-source web analysis service Matomo. Matomo uses technologies that make it possible to recognize the user across multiple pages with the aim of analyzing the user patterns (e.g. cookies or device fingerprinting). The information recorded by Matomo about the use of this website will be stored on our server. Prior to archiving, the IP address will first be anonymized.

Through Matomo, we are able to collect and analyze data on the use of our website-by-website visitors. This enables us to find out, for instance, when which page views occurred and from which region they came. In addition, we collect various log files (e.g. IP address, referrer, browser, and operating system used) and can measure whether our website visitors perform certain actions (e.g. clicks, purchases, etc.).

The use of this analysis tool is based on Art. 6(1)(f) GDPR. The website operator has a legitimate interest in the analysis of user patterns, in order to optimize the operator’s web offerings and advertising. If appropriate consent has been obtained, the processing is carried out exclusively on the basis of Art. 6(1)(a) GDPR and § 25 (1) TTDSG, insofar the consent includes the storage of cookies or the access to information in the user’s end device (e.g., device fingerprinting) within the meaning of the TTDSG. This consent can be revoked at any time.

IP anonymization

For analysis with Matomo we use IP anonymization. Your IP address is shortened before the analysis, so that it is no longer clearly assignable to you.

Hosting

We host Matomo with the following third-party provider:

jungepartner
Wullener Feld 60
58452 Witten

Data processing

We have concluded a data processing agreement (DPA) with the above-mentioned provider. This is a contract mandated by data privacy laws that guarantees that they process personal data of our website visitors only based on our instructions and in compliance with the GDPR.

6. Plug-ins and Tools

YouTube with expanded data protection integration

Our website embeds videos of the website YouTube. The website operator is Google Ireland Limited (“Google”), Gordon House, Barrow Street, Dublin 4, Ireland.

We use YouTube in the expanded data protection mode. According to YouTube, this mode ensures that YouTube does not store any information about visitors to this website before they watch the video. Nevertheless, this does not necessarily mean that the sharing of data with YouTube partners can be ruled out as a result of the expanded data protection mode. For instance, regardless of whether you are watching a video, YouTube will always establish a connection with the Google DoubleClick network.

As soon as you start to play a YouTube video on this website, a connection to YouTube’s servers will be established. As a result, the YouTube server will be notified, which of our pages you have visited. If you are logged into your YouTube account while you visit our site, you enable YouTube to directly allocate your browsing patterns to your personal profile. You have the option to prevent this by logging out of your YouTube account.

Furthermore, after you have started to play a video, YouTube will be able to place various cookies on your device or comparable technologies for recognition (e.g. device fingerprinting). In this way YouTube will be able to obtain information about this website’s visitors. Among other things, this information will be used to generate video statistics with the aim of improving the user friendliness of the site and to prevent attempts to commit fraud.

Under certain circumstances, additional data processing transactions may be triggered after you have started to play a YouTube video, which are beyond our control.

The use of YouTube is based on our interest in presenting our online content in an appealing manner. Pursuant to Art. 6(1)(f) GDPR, this is a legitimate interest. If appropriate consent has been obtained, the processing is carried out exclusively on the basis of Art. 6(1)(a) GDPR and § 25 (1) TTDSG, insofar the consent includes the storage of cookies or the access to information in the user’s end device (e.g., device fingerprinting) within the meaning of the TTDSG. This consent can be revoked at any time.

For more information on how YouTube handles user data, please consult the YouTube Data Privacy Policy under: https://policies.google.com/privacy?hl=en.

Google Maps

This website uses the mapping service Google Maps. The provider is Google Ireland Limited (“Google”), Gordon House, Barrow Street, Dublin 4, Ireland.

To enable the use of the Google Maps features, your IP address must be stored. As a rule, this information is transferred to one of Google’s servers in the United States, where it is archived. The operator of this website has no control over the data transfer. In case Google Maps has been activated, Google has the option to use Google web fonts for the purpose of the uniform depiction of fonts. When you access Google Maps, your browser will load the required web fonts into your browser cache, to correctly display text and fonts.

We use Google Maps to present our online content in an appealing manner and to make the locations disclosed on our website easy to find. This constitutes a legitimate interest as defined in Art. 6(1)(f) GDPR. If appropriate consent has been obtained, the processing is carried out exclusively on the basis of Art. 6(1)(a) GDPR and § 25 (1) TTDSG, insofar the consent includes the storage of cookies or the access to information in the user’s end device (e.g., device fingerprinting) within the meaning of the TTDSG. This consent can be revoked at any time.

Data transmission to the US is based on the Standard Contractual Clauses (SCC) of the European Commission. Details can be found here: https://privacy.google.com/businesses/gdprcontrollerterms/ and https://privacy.google.com/businesses/gdprcontrollerterms/sccs/.

For more information on the handling of user data, please review Google’s Data Privacy Declaration under: https://policies.google.com/privacy?hl=en.

Google reCAPTCHA

We use “Google reCAPTCHA” (hereinafter referred to as “reCAPTCHA”) on this website. The provider is Google Ireland Limited (“Google”), Gordon House, Barrow Street, Dublin 4, Ireland.

The purpose of reCAPTCHA is to determine whether data entered on this website (e.g., information entered into a contact form) is being provided by a human user or by an automated program. To determine this, reCAPTCHA analyzes the behavior of the website visitors based on a variety of parameters. This analysis is triggered automatically as soon as the website visitor enters the site. For this analysis, reCAPTCHA evaluates a variety of data (e.g., IP address, time the website visitor spent on the site or cursor movements initiated by the user). The data tracked during such analyses are forwarded to Google.

reCAPTCHA analyses run entirely in the background. Website visitors are not alerted that an analysis is underway.

Data are stored and analyzed on the basis of Art. 6(1)(f) GDPR. The website operator has a legitimate interest in the protection of the operator’s websites against abusive automated spying and against SPAM. If appropriate consent has been obtained, the processing is carried out exclusively on the basis of Art. 6(1)(a) GDPR and § 25 (1) TTDSG, insofar the consent includes the storage of cookies or the access to information in the user’s end device (e.g., device fingerprinting) within the meaning of the TTDSG. This consent can be revoked at any time.

For more information about Google reCAPTCHA please refer to the Google Data Privacy Declaration and Terms Of Use under the following links: https://policies.google.com/privacy?hl=en and https://policies.google.com/terms?hl=en.

7. Custom Services

Handling applicant data

We offer website visitors the opportunity to submit job applications to us (e.g., via e-mail, via postal services on by submitting the online job application form). Below, we will brief you on the scope, purpose and use of the personal data collected from you in conjunction with the application process. We assure you that the collection, processing, and use of your data will occur in compliance with the applicable data privacy rights and all other statutory provisions and that your data will always be treated as strictly confidential.

Scope and purpose of the collection of data

If you submit a job application to us, we will process any affiliated personal data (e.g., contact and communications data, application documents, notes taken during job interviews, etc.), if they are required to make a decision concerning the establishment or an employment relationship. The legal grounds for the aforementioned are § 26 GDPR according to German Law (Negotiation of an Employment Relationship), Art. 6(1)(b) GDPR (General Contract Negotiations) and – provided you have given us your consent – Art. 6(1)(a) GDPR. You may revoke any consent given at any time. Within our company, your personal data will only be shared with individuals who are involved in the processing of your job application.

If your job application should result in your recruitment, the data you have submitted will be archived on the grounds of § 26 GDPR and Art. 6(1)(b) GDPR for the purpose of implementing the employment relationship in our data processing system.

Data Archiving Period

If we are unable to make you a job offer or you reject a job offer or withdraw your application, we reserve the right to retain the data you have submitted on the basis of our legitimate interests (Art. 6(1)(f) GDPR) for up to 6 months from the end of the application procedure (rejection or withdrawal of the application). Afterwards the data will be deleted, and the physical application documents will be destroyed. The storage serves in particular as evidence in the event of a legal dispute. If it is evident that the data will be required after the expiry of the 6-month period (e.g., due to an impending or pending legal dispute), deletion will only take place when the purpose for further storage no longer applies.

Longer storage may also take place if you have given your agreement (Article 6(1)(a) GDPR) or if statutory data retention requirements preclude the deletion.
