These rights include, among others, the right to access the data stored about you, the right to rectify inaccuracies, and, where the legal requirements are met, the right to have your data erased. 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.

Right of access, Art. 15 GDPR

According to Article 15 of the GDPR (General Data Protection Regulation), you have the right to obtain from us confirmation as to whether or not personal data concerning you are being processed and where that is the case, access to the personal data including the following information.

We will inform you about:

  • The purpose of the processing
  • The categories of personal data concerned
  • 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
  • Whether we process data that we did not collect directly from you, and if so, the source of that data
  • The existence of automated decision-making

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

According to Article 17 of the GDPR (General Data Protection Regulation), you can also request the erasure of your data if one of the following situations applies:

  • 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  • You have withdrawn your consent for the processing, and there is no other legal basis for the processing.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.
  • Your data has been unlawfully processed.
  • The erasure of data is required to fulfill a legal obligation under the Union or Member State law.

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.

During the evaluation of your rights mentioned above, you can choose to have the processing of your data restricted.

Right to data portability, Art. 20 GDPR

Furthermore, according to Article 20 of the GDPR (General Data Protection Regulation), you have the right to receive the personal data concerning you, which you have provided to us, in a structured, commonly used, and machine-readable format. 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.

Right to object, Art. 21 GDPR

If we process your data based on legitimate interests according to Article 6 (1) (f) of the GDPR (General Data Protection Regulation), you have the right, under Article 21 of the GDPR, to object to the processing of your data. This right applies if there are reasons arising from your particular situation or if the objection is directed against direct marketing. In the latter case, you have a general right to object, which we will implement even without stating specific reasons.

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. The withdrawal of consent does not affect the lawfulness of the processing based on consent before its withdrawal, as stated in Article 7 (3), Sentence 2 of the GDPR.

If you withdraw your consent, we will cease the processing of data that was based on that consent.

Right to file a complaint, Art. 57 GDPR

Finally, you have the right to lodge a complaint with the supervisory authority that is responsible for us, as outlined in Article 77 (1) (f) of the GDPR (General Data Protection Regulation). You can exercise this right by contacting the supervisory authority in the member state where you have your habitual residence, your place of work, or the place of the alleged infringement.
