We declare

We declare that, as the controller of your personal data, we comply with all legal obligations required by applicable legislation, in particular the Data Protection Act and the GDPR, and therefore that:

  • we will only process your personal data based on a valid legal ground, in particular a legitimate interest, the performance of a contract, a legal obligation or consent,
  • we comply with the information obligation under Article 13 of the GDPR before we start processing personal data,
  • enable and support you in exercising and fulfilling your rights under the Data Protection Act and the GDPR.

Scope of personal data and purposes of processing

We process personal data that you entrust to us for the following reasons (to fulfill these purposes):

  • Provision of services and performance of a contract
    Your personal data in the following scope: billing data, e-mail, telephone, or correspondence address, if necessary, is necessary for the performance of the contract
  • Bookkeeping
    If you are a customer, we necessarily need your personal data (billing data) to comply with the legal obligation to issue and record tax documents.
  • Marketing - sending newsletters

We use your personal data (email and name), gender, what you click on in the email and when you open it most often for direct marketing purposes - sending you commercial communications. If you are a customer, we do this out of legitimate interest, as we reasonably assume that you are interested in our newsletter, and for a period of 10 years from your last order. If you are not our customer, we only send you newsletters based on your consent, for a period of 10 years from the date of issue. If we come across someone else interesting work, we will be happy to recommend their work in an email. In either case, you can withdraw this consent by using the unsubscribe link in any email sent.


When you browse our website, we record your IP address, how long you stay on the site and which page you come from. We see the use of cookies to measure website traffic and to customize the display of the website as a legitimate interest of our administrator, as we believe that this allows us to offer you an even better service.

Cookies for advertising targeting will only be processed based on your consent.

Our website can also be browsed in a mode that does not allow the collection of personal data. You can disable the use of cookies on your computer in your internet browser.

Security and protection of personal data

We protect personal data to the maximum extent possible by using modern technologies that correspond to the state of the art. We protect it as if it were our own. We have adopted and maintain all possible (currently known) technical and organizational measures to prevent the misuse, damage or destruction of your personal data.

Transfer of personal data to third parties

Your personal data can be accessed by our employees and third parties who are bound by confidentiality and trained in the security of personal data processing.

For some specific processing operations that we are unable to provide on our own, we use the services and applications of processors who specialize in that processing and are GDPR compliant.

These are providers of the following platforms and services:

- SmartEmailing

- Facebook - FB pixel

- Google and Seznam - Google Analytics and Sklik

It is possible that in the future we may decide to use other applications or processors to facilitate and improve the quality of processing. However, we promise you that in such a case, we will place at least the same demands on the processor for security and quality of processing as we do on ourselves.

Data transfer outside the European Union

We only process data in the European Union or in countries that provide an adequate level of protection based on a decision of the European Commission.

Your rights in relation to data protection

You have a number of rights in relation to data protection. If you wish to exercise any of these rights, please contact us by email:

You have the right to information, which is already fulfilled by this information page with the personal data processing policy.

Thanks to the right of access, you can challenge us at any time, and we will document within 30 days which of your personal data we process and why.

If something changes or you find your personal data outdated or incomplete, you have the right to have your personal data completed and amended.

You can exercise your right to restrict processing if you believe that we are processing your inaccurate data, if you believe that we are processing unlawfully but do not want to delete all your data, or if you have objected to the processing.

You can limit the scope of personal data or the purposes of processing. (For example, by unsubscribing from the newsletter you limit the purpose of processing for sending commercial communications.)

Right to erasure (to be forgotten)

Another right you have is the right to erasure (to be forgotten). We do not want to forget you, but you have the right to do so if you wish. In this case, we will erase all your personal data from our system and from the system of all sub-processors and backups. We need 30 days to secure the right to erasure.

In some cases, we are bound by a legal obligation and, for example, we must keep records of tax documents issued for the period of time specified by law. In this case, we will therefore delete all such personal data that is not bound by another law. We will inform you by email when the deletion is completed.

Complaint to the Office for Personal Data Protection

If you feel that we are not treating your data in accordance with the law, you have the right to complain to the Data Protection Authority at any time. We would be very happy if you would first inform us of this suspicion so that we can do something about it and correct any wrongdoing.

Unsubscribing from newsletters and commercial communications

We send you emails with inspiration, articles, or products and services if you are a customer based on our legitimate interest.

If you are not yet a customer, we only send them to you based on your consent. In either case, you can stop receiving our emails by pressing the unsubscribe link in each email sent.


We would like to assure you that our employees and third parties who will process your personal data are obliged to maintain the confidentiality of personal data and security measures, the disclosure of which would compromise the security of your personal data. This confidentiality shall continue even after the end of the contractual relationship with us. Your personal data will not be released to any other third party without your consent.
