Providing your personal data is always voluntary, but necessary to place an order, subscribe to the newsletter, add a comment on our blog or simply contact us.

We guarantee the confidentiality of all your personal data. We ensure that all security and personal data protection measures required by appropriate provisions of the law are taken. Personal data is collected with due diligence and properly protected against access by unauthorized persons. Personal data is processed within the European Union and the USA.

We entrust the processing of personal data to the following entities:

  • Fakturownia – to use the invoicing system, 
  • Biuro Rachunkowe Kazimierz Borowski, our accounting service provider,
  • Mail Chimp – to use the mailing system,
  • WooCommerce – to use the e-commerce system

The Mail Chimp mailing system uses servers located outside the EU, which means your personal data is transferred to a third country, in this case the USA. The provider of the mailing system guarantees an appropriate level of protection and security of personal data.


Via our website, you can subscribe to a newsletter with information about new products, promotions, products and services related to our online activity. To send the newsletter, we must process your personal data (name and e-mail address).

In the case of the newsletter, the legal justification for the processing of your personal data is your consent expressed by clicking the link in the e-mail confirming the subscription to the newsletter. You can withdraw your consent at any time by canceling your newsletter subscription.
The data is processed for the duration of the newsletter, unless you unsubscribe from it, which will delete the data from our database.


When placing an order, you must provide your personal data necessary to process the order, i.e. name and surname, e-mail address (and in the case of physical products, telephone number and address for order delivery).

The data provided in the order form will be saved in our database and will be stored there until the claims for the concluded contract are time-barred. Each order is recorded as a separate item in the database. In addition to personal data, order details such as the date of placing the order, subject and value of the order are also recorded.


If we issue an invoice, we process your personal data to the extent necessary to issue an invoice. The legal justification for the processing of your data in this case is the fulfillment of the legal obligation to issue an invoice.
