Personal data protection and safety

We protect personal data to the maximum extent using modern technology that is in accordance with the degree of technological development. We protect it as if it was our own. We have adopted and maintain all possible (currently known) technical and organisational measures that prevent abuse, damage, or destruction of your personal data.

Transferring personal data to third parties

Our employees and co-workers have access to your personal data. For specific processing operations that we are unable to manage on our own, we utilise the service and applications of processors who are able to protect data even better than we are, and specialise in this type of processing. These include the following processors:

  • operator of applications for communication, the web, and invoicing,
  • operator of applications for e-mail correspondence and customer support,
  • Facebook, Google,
  • accounting and tax advising providers,
  • IT service and hosting providers, including cloud servers,
  • assistant service providers for customer support,
  • payment gateway providers (payment card providers),
  • legal service providers, lawyers,
  • printing and postal service providers,
  • used plugin providers,
  • partners collaborating with us in special events for clients.

It is possible that we may decide to utilise additional applications or processors in the future, for easier and higher-quality processing. However, we promise that I will expect a minimum of the same requirement for the protection and quality of the processing as I would for myself during the selection process.
