3.General information and mandatory information

Data protection

The site operators take the protection of your personal data very seriously. We treat your personal data in confidence and in line with legal data protection provisions, as well as this data protection declaration.

If you use this website, various personal data are collected. Personal data are data that can be used to identify you personally. The present data protection declaration explains which data we collect and why we use them. It also explains how this happens and for what purpose.

We would like to draw your attention to the fact that transferring data via the internet (e.g. when communicating by email) may be subject to security vulnerabilities. It is not possible to protect data completely from third-party access.

Information concerning the responsible party

The party responsible for processing data on this website is:

Rheinkalk GmbH
Am Kalkstein 1
42489 Wülfrath

Telephone: +49 (0)2058 170

A responsible party is a natural or legal person who decides upon the purpose and means of processing personal data (e.g. names, email addresses, etc.) alone or with others.

Storage period

Unless a specific storage period has been mentioned within this data protection declaration, your personal data are stored by us until the purpose for their processing lapses. If you make a legitimate request for deletion or revoke your consent to data processing, your data will be deleted providing we do not have other lawful grounds for storing your personal data (e.g. retention periods applicable under tax or commercial law); in the latter case, deletion takes place once these reasons lapse.

Statutory data protection officer

We have appointed a data protection officer for our company:

Dr Jörn Vossbein (UIMC Dr. Voßbein GmbH & Co. KG)
Otto-Hausmann-Ring 113
42115 Wuppertal

Telephone: +49 (0)202 946 772 6200

Revocation of your consent to data processing

Many data processing operations are only possible with your express consent. You may revoke consent that has been previously granted at any time. The lawfulness of data processing that has been conducted prior to revocation remains unaffected.

The right to object to the collection of data in specific cases, as well as to direct advertising (Art. 21 GDPR)

If data processing is conducted on the basis of Art. 6 para. 1(e) or (f) GDPR, you have the right to object to the processing of your personal data for reasons arising from your specific situation at any time; this also applies to profiling based on these provisions. The respective legal foundation on which processing is based can be found in this data protection declaration. If you file an objection, we will no longer process the personal data in question unless we are able to prove compelling and legitimate grounds for their processing that prevail over your interests, rights and freedoms, or if processing facilitates the assertion, exercising or defence of legal claims (objection in accordance with Art. 21 para. 1 GDPR).

If your personal data are processed to conduct direct advertising, you have the right to file an objection to the processing of your personal data for the purposes of this type of advertising at any time; this also applies to profiling if this occurs in connection with this type of direct advertising. If you object, your personal data will then no longer be used for the purposes of direct advertising (objection in accordance with Art. 21 para. 2 GDPR).

Right to appeal to the competent regulatory authority

In the event of infringements against the GDPR, the affected party has the right to appeal to a regulatory authority, especially in the member state in which they are usually resident, in which they work or where the suspected infringement has occurred. The right to appeal exists without prejudice to other administrative or judicial remedies.

Right to data portability

You are entitled to have data that we process with your consent or automatically for the fulfilment of a contract transferred to you or to a third party in a conventional, machine-readable format. If you request the direct transfer of data to another responsible party, this only takes place if this is technically feasible.

SSL/TLS encryption

For security reasons and to protect the transfer of confidential content such as orders or enquiries that you send to us as the site operator, this site uses SSL/TLS encryption. You can recognise an encrypted connection by the fact that the address field switches from ‘http://’ to ‘https://’ and a padlock symbol appears in the browser field.

If SSL/TLS encryption is activated, data that you transfer to us cannot be read by third parties.

Information, deletion and correction

Within the scope of the applicable legal provisions, you have the right to be informed at any time and free of charge regarding your stored personal data, their origin, recipients and the purpose of their processing, as well as a right to correct or delete these data, where appropriate. You may contact us at any time in this regard, as well as with any other questions concerning personal data.

Right to restrict processing

You have the right to request that processing of your personal data be restricted. You may contact us at any time for this purpose. The right to restrict processing applies in the following cases:

  • If you dispute the accuracy of your personal data stored by us, we generally require time to verify this. You have the right for the duration of this verification to request that processing of your personal data be restricted.
  • If the processing of your personal data was unlawful, you may request the restriction of data processing rather than deletion.
  • If we no longer require your personal data, but you require them for the assertion, defence or enforcement of legal claims, you have the right to request that processing of your personal data be restricted rather than these data being deleted.
  • If you have filed an objection in accordance with Art. 21 para. 1 GDPR, an assessment must be made as to whose interests prevail. If this has not yet been established, you have the right to request that processing of your personal data be restricted.

If you have restricted the processing of your personal data, these data – excluding their storage – may only be processed with your consent or for the assertion, exercising or defence of legal claims, or to protect the rights of another natural or legal person, or for reasons of substantial public interest on the part of the European Union or one of its member states.

They are stored on your end device either temporarily during a session (session cookies) or permanently (permanent cookies). Session cookies are automatically deleted once your visit ends. Permanent cookies remain stored on your end device until you delete them yourself or your web browser deletes them automatically.

Cookies from third parties may sometimes be stored on your end device if you visit our site (third-party cookies). These make it possible for us or you to use specific third-party services (e.g. cookies for processing payment services).

Cookies have various functions. Many cookies are a technical requirement because specific website features would not function without them (e.g. the shopping basket or video display). Other cookies are used to evaluate user behaviour or to display advertising.

Cookies that are necessary for the implementation of electronic communication procedures (required cookies) or the provision of specific functions that you require (functional cookies, e.g. for the shopping basket) or for website optimisation (e.g. cookies to measure website traffic) are stored based on Art. 6 para. 1(f) GDPR providing no other legal basis is specified. The website operator has a legitimate interest in storing cookies for the technically fault-free and optimised provision of its services. If consent is requested for the storage of cookies, the cookies in question are stored exclusively based on this consent (Art. 6 para. 1(a) GDPR); consent may be revoked at any time.

Cookie consent with Borlabs Cookie

Our website uses cookie consent technology from Borlabs Cookie in order to obtain your consent to the storage of specific cookies on your browser and to document this in a data protection–compliant manner. This technology is provided by Borlabs – Benjamin A. Bornschein, Georg-Wilhelm-Str. 17, 21107 Hamburg, Germany (hereafter Borlabs).

If you access our website, a Borlabs cookie will be stored on your browser and your consent or revocation of this consent will be saved there. These data are not forwarded to the provider of Borlabs Cookie.

The collected data are stored until you request that we delete them or you delete the Borlabs cookie yourself, or the reason for storing the data lapses. Statutory retention periods remain unaffected. Details regarding data processing by Borlabs cookies can be found at

Borlabs cookie consent technology is employed to obtain statutory consent for the use of cookies. The legal basis for this is Art. 6 para. 1 item 1(c) GDPR.

Server log files

The website provider automatically collects and stores information in so-called server log files, which your browser transfers to us automatically. These data include:

  • Browser type and browser version
  • Operating system used
  • Referrer URL
  • Host name of the accessing computer
  • Time of server request
  • IP address

These data are not pooled with other data sources.

These data are collected on the basis of Art. 6 para. 1(f) GDPR. The website operator has a legitimate interest in the technically fault-free display and optimisation of its website – for this reason, server log files must be collected.

Email, telephone or fax enquiries

If you contact us by email, telephone or fax, your enquiry will be stored and processed by us, including all resulting personal data (name, enquiry), for the purposes of processing your request. These data will not be transferred without your consent.

These data are processed based on Art. 6 para. 1(b) GDPR provided that your enquiry concerns the fulfilment of a contract or this is required for the implementation of precontractual steps. In all other cases, processing is based on our legitimate interest regarding the effective processing of the enquiry directed to us (Art. 6 para. 1(f) GDPR) or on your consent (Art. 6 para. 1(a) GDPR) if this has been requested.

We retain data transferred to us by you via contact enquiries until you request their deletion, revoke your consent to their storage, or the purpose for storing the data lapses (e.g. once the processing of your request has been completed). Statutory provisions – especially statutory retention periods – remain unaffected.
