Whenever we ask for your consent to process your data, you also have the right to withdraw your consent at any time and without providing any reasons.

  • Recipients or categories of recipients of the personal data
  • The planned duration of storage (or the criteria used to determine this duration)
  • The existence of your rights regarding the processing

When you request information about your data, we will provide you with comprehensive details on how your data is processed, its origin, and where it is transmitted to.

Right to rectification, Art. 16 GDPR

If any data stored by us is incorrect or no longer up to date, you have the right, in accordance with Article 16 of the GDPR (General Data Protection Regulation), to request the rectification of such data. We will promptly comply with your request.

When requesting a correction, you can provide us with the accurate data, and we will take care of the rest.

Right to erasure, Art. 17 GDPR

  • The data is no longer necessary for the purposes for which it was collected.
  • You have withdrawn your consent for the processing, and there is no other legal basis for the processing.
  • You have objected to the processing under Article 21 (1) or (2) of the GDPR (see below), and there are no overriding legitimate grounds for the processing.

If erasure is not possible due to other legal obligations, the data will be blocked and made available only for the purpose of fulfilling those legal obligations. 

If we have unlawfully processed data, we will promptly delete it.

Right to restriction of processing, Art. 18 GDPR

You have the right, as stated in Article 18 of the GDPR (General Data Protection Regulation), to request the restriction of the processing of your data if you believe that the data we have stored is inaccurate, the processing is unlawful, the personal data is no longer needed for its original purpose, or if you have objected to the processing.

You have the right to transmit this data to another data controller if the processing is based on your consent (Article 6(1)(a) of the GDPR) or on a contract between us (Article 6(1)(b) of the GDPR).

If you request the transfer of the data you have provided to us, we will provide it to you in a portable format.

If you exercise your right to object, we will assess whether there are compelling legitimate grounds for the processing on our part. If there are no such grounds, we will cease processing the data.

According to Article 7 (3), Sentence 1 of the GDPR (General Data Protection Regulation), you have the right to withdraw your consent at any time by notifying us at This withdrawal of consent will result in us no longer continuing the data processing based on that consent in the future.
