RENA Technologies GmbH privacy policy

We thank you for your interest in our company and our products and services, and would also like you to feel comfortable about the protection of your personal data when visiting our website. We are subject to the provisions of the European General Data Protection Regulation (GDPR) as well as the supplementary regulations of the German Federal Data Protection Act (BDSG). To ensure that the data protection requirements are fulfilled both by us and our external service providers we have implemented suitable technical and organizational measures.

This privacy policy applies to our online offers. It covers websites, functions, and content as well as online presence away from the website, such as our use of social media. This general privacy policy is also intended to make you aware of further processing of your personal data and our fulfillment of the information obligations to you.

The terms used in this privacy policy, for example controller or personal data are used in accordance with the definitions in the GDPR. For reasons of readability and also for conveying information comprehensibly, the quoting of individual articles, paragraphs, etc., is generally dispensed with.

General information on the processing of data

Legal basis for the processing of personal data

Under statutory data protection regulations, processing of personal data is generally not allowed, unless there is a legally permitted reason for such authorization. We are obligated to make you aware of the legal basis for any data processing.

When we obtain your consent to process personal data, this provides legal basis.

When processing personal data is required for the performance of a contract to which you are a party, the performance of the contract provides legal basis. This also applies to processing procedures required prior to entering into a contract.

Where processing of personal data is required for compliance with a legal obligation to which we are subject, this provides legal basis.

Where the vital interests of the data subject, or another natural person, make the processing of personal data necessary, this provides legal basis.

If the processing is required to protect a legitimate interest pursued by our company or a third party and these interests do not override your fundamental rights and freedoms, then this provides legal basis.


Transfer of data to third countries

The GDPR guarantees a uniformly high level of data protection within the European Union (EU) and the European Economic Area (EEA). When selecting our service providers and partners, where possible we give preference to European partners if your personal data is to be processed.

Where we have your data processed in a third country, i.e. outside the EU/EEA, this is always done in accordance with statutory requirements.

Along with your specific consent, or contractually or legally required communication, we only allow your data to be processed in third countries with a recognized level of data protection from a contractual obligation by “standard contract clauses” of the European Commission, on production of certification or mandatory internal data protection regulations.


Existence of automated decision-making

We do not use automated decision-making or profiling.


Recipients of data/categories of recipients

Within our company, we ensure that only those persons receive your data, who require it to fulfill contractual and statutory obligations.

Occasionally, we make use of carefully selected external service providers for the processing of your data. If data is forwarded to service providers as part of order processing, then this is done subject to GDPR regulations. Our order processors are carefully selected and bound by our instructions. They are checked at regular intervals. We only use those order processors that provide sufficient guarantee that appropriate technical and organizational measures are in place so that the processing is done in accordance with the requirements of the GDPR and the BDSG, and the protection of your rights is guaranteed.


Forwarding of personal data to third parties

Generally, we do not forward personal data to third parties without your specific consent. Where we do, however, disclose your data to third parties, forward it to them, or provide them with other access to the data, this is done exclusively based on one of the legal foundations set out above.

By way of example, we forward data to payment service providers or suppliers where this is required for contract fulfillment. If we are obliged to do so legally, or as a result of a court decision, we must forward your data to the particular authorities entitled receive the information.



Use of our online offer

In principle, you can use our online offer without revealing your identity. In this section, we explain when and in what context we process data when using our online offer, which offers by service providers and partners we have implemented, how they work, and what happens to your data.



Our offer is essentially directed towards adults. Persons under 16 years are not allowed to forward personal data to us without the permission of their parents or guardians.


Transport encryption

In order to protect your forwarded data in the best way possible, we use “transport encryption”. In order to guarantee the security of your data during the forwarding process, we use a state-of-the-art SSL/TLS encryption procedure.


Data collection when visiting our website

Provided you use our website solely for information purposes and you neither register for an offer nor conclude a contract with us, or reveal information in any other way, we only gather the personal data that your browser sends to our server.

When visiting our website, we only gather the data technically necessary to display our website to you, and to ensure stability and security as set out below:

  • IP address of the visitor
  • Date and time of the inquiry
  • Content of the request (specific page)
  • Access status/HTTP status code
  • Specific volume of data transferred
  • Website from which the request comes
  • Operating system of the visitor
  • Language and version of the browser software

This data is temporarily retained in the log files of our system for a maximum of seven days. Further storage is possible, but in this case the IP addresses are abbreviated or obscured so that identification of the inquiring client is no longer possible. Storage of the log files, along with other personal data related to you, does not take place in this context. The legal basis for these processing procedures is our legitimate interest.

As the gathering of data to display the website and the storage of data in log files is absolutely essential for the operation of our website and for the maintenance of IT security, you have no right of objection.


Inquiries to us

Should you make an inquiry to us via our website, for example by using the contact form, your personal data will be processed to answer your inquiry.



Information on services used

Google Maps

In order to indicate the location of our sites, we use links to display the site in question to you on Google maps. This involves a service by Google LLC, Gordon House, 4 Barrow Street, Dublin, Ireland (referred to as Google below).

On clicking the link, the map is showed in a separate tab in your browser. By calling up this link, you leave our website and immediately enter into a user relationship with Google. More detailed information on usage conditions and data protection with Google can be obtained here.


General information on the use of cookies

In addition to the above-mentioned data, when using our website, cookies are stored on your terminal device during your visit. Cookies are small text packages that can be sent from a website to the browser and stored by it, and then returned. Various types of information can be stored in cookies that can be read by the entity placing the cookie. They generally contain a characteristic string (ID) that enables explicit identification of the browser when the website is visited again, or when moving to another page. Their primary purpose is to make our online offers overall more user-friendly and effective. The user data gathered in cookies is pseudonymized by technical processes, whereby association of the data with the visiting user is generally no longer possible. If identification is provided, such as with a login cookie, the session ID, which is necessarily is linked with the user’s account, we will make you aware of this at the appropriate point.

We use various types of cookie:

  • “Session cookies” are cookies that are deleted once you have left our online offer and closed the browser. In this type of cookie are stored such things as language settings, or the contents of a shopping basket.
  • “Permanent cookies” remain stored after the browser has been closed, allowing such things as the login status or search criteria to be stored. We use cookies for things such as analytics or marketing purposes. “Persistent cookies” are automatically deleted after a prescribed period that can vary according to the cookie. You can, however, delete these cookies at any time using your browser or other means.

In addition to “first-party cookies”, which are set by us as controllers for data processing, “third-party cookies” are also used that are offered by other providers.

  • “First party cookies” are set by us as controllers.
    The legal basis for the processing of your personal data in this case is our legitimate interest.
  • External service providers, who carry out such things as web tracking or analytics for us, can also set cookies.
    The legal basis for the processing of your personal data is your consent.

Privacy policy of the provider



We offer you the opportunity to subscribe to our free e-mail newsletter. We only send this newsletter with your consent. When signing up to a newsletter, the data from the input screen (name and e-mail address) is forwarded to us and stored for as long as the subscription to the newsletter remains active.

Your consent is obtained for the processing of this data for the purpose of sending the newsletter and you are referred to this privacy policy. We use the “double opt-in procedure” for the signing-up process. After signing up successfully, you receive an e-mail in which you must click on a link to confirm registration. In this way, we prevent unauthorized third parties from signing up using your e-mail address.

We record the signing-up process in order to show that it is in line with statutory requirements. For this purpose, the IP address of the requesting terminal device, and the date and time of signing up are recorded. The data you provide is stored for as long as the subscription remains active.

You are free to cancel the subscription at any time. For this purpose, in each newsletter there is a corresponding unsubscribe link. This also allows you to withdraw your consent. The legal basis for the processing of your data is your freely given consent to receive the newsletter.

If you obtain goods or services from us and give your e-mail address when doing so, we reserve the right to use it to send newsletters directly marketing our own similar goods or services. This is to safeguard our overriding legitimate interest as part of the balancing of interests in promoting advertising to our customers. By sending a message to the contacts listed below, or by using the unsubscribe link in the advertising e-mail, you can withdraw consent for this use of your data at any time and without any costs other than the transmission costs at basic rates. Where the newsletter is sent on the basis of the sale of goods or services, we refer to the requirements of the German Act Against Unfair Competition (UWG).


Commercial and business services

We process the data of our contractual and business partners, e.g. suppliers, customers, and interested parties (hereafter business partners) as part of contractual or equivalent legal relationships as well as associated actions and in the context of communication with our business partners.

We process this data to fulfill our contractual obligations, to secure our rights, and for the purpose of the associated administrative tasks, as well as our corporate organization. We only pass on the data of our business partners within the framework of the applicable legislation to the extent that this is required for the above purposes or for the fulfillment of statutory obligations or with the consent of the data subjects (e.g. participating telecommunications, transport, and other support services as well as sub-contractors, banks, taxation and legal advisers, payment services, or the tax authorities). Contractual partners are made aware of other forms of processing, e.g. for marketing purposes, in this privacy policy.

We inform the contractual partners of what data is required for the above purposes prior to, or as part of, data collection, or personally.


Erasure of data and duration of storage

As soon as the purpose for the processing no longer exists, we erase or block your personal data. Storage can extend beyond this period, however, if this is necessary according to statutory provisions to which we are subject. Above all, this affects data that must be retained for reasons of statutory archiving (e.g. for reasons of commercial law, generally for 6 years, or for reasons of tax law, generally for 10 years).


Data processed:

Listing data (e.g. names, addresses), payment data (e.g. bank details, invoices, payment history), contact data (e.g. e-mail addresses, telephone numbers), contract data (e.g. subject of the contract, duration).


Purposes of the processing:

Delivery of contractual and customer services, contact inquiries and communication, internal organizational processes, management, and responding to inquiries.


Legal foundations:

Contract performance/pre-contract inquiries, statutory obligation, legitimate interests.


Your rights as a data subject

As a data subject, you have various rights, which we would like to make you aware of below. Dependent upon the rationale and nature of the processing of your personal data, you have the rights described in the following paragraphs.


Your right of access

As a data subject, you have the right to find out from us whether we process your personal data and, if this is the case, what personal data we process.

You also have the right to request a copy of your personal data that is the subject of the processing.


Your right to rectification

You have the right to request that we immediately rectify any of your personal data that you consider to be inaccurate.

You also have the right to request that we complete any of your personal data that you consider to be incomplete.


Your right to erasure

On presentation of the statutory requirements, you may request the erasure of your personal data.

This is the case, for example, when we process your data based on your consent, which you subsequently withdraw.

However, we may not erase any data if we have to keep it for statutory retention periods. We can also not comply with your erasure request if it is necessary for us to process your personal data to establish, exercise, or defend against legal claims.


Your right to restriction of processing

As a data subject, under certain conditions you have the right to request that we restrict the processing of your personal data.

One of these conditions is, for example, that you contest the accuracy of your personal data. There is also the case where we no longer require your personal data, but you require it to establish, exercise, or defend against legal claims.


Your right to object

If we process your personal data on the basis of a legitimate interest, you have the right to object to this processing if this arises as a result of your particular situation.  This right to object does not exist, however, where there is a compelling public interest in the processing that overrides your interest and legally obligates us to carry out the processing, or the processing is to establish, exercise, or defend against legal claims.

If we use your personal data for direct marketing, then you have the right to lodge an objection at any time against processing for the purpose of such marketing. If you do raise objection to processing for this purpose, your personal data will no longer be used for this.

If we process your data based on your consent, then you have the right to withdraw the consent at any time to take effect in the future. The legality of the processing carried out up to the time the withdrawal request is lodged remains unaffected.


Your right to data portability

This right is only available to you in respect of such personal data that you have provided us with yourself. You have the right to request us to transmit this personal data directly to another controller.

Alternatively, you have the right to request that we provide you with your data in a machine-readable format. This only applies, however, if we process your personal data based on your consent, or a contract, and the processing is done by automated means.


Complaint to supervisory authorities

You also have the right to lodge a complaint with a supervisory authority, if you are of the view that the processing of your personal data contravenes the provisions of data protection law.



This privacy policy is amended from time to time. By way of example, these amendments are made if changes arise as a result of technical progress, statutory requirements, or other influences.
