Scope of the Privacy Statement

WFNS values privacy and is committed to protecting the personal data of all its stakeholders with the utmost care. We process personal data only in a fair and lawful manner. This Privacy Statement applies to our members and website visitors concerning the personal data collected and processed by WFNS through this website and related services.

This Privacy Statement provides essential information on how WFNS, as the data controller, collects and processes personal data, the purposes for which this data is used, and your rights as a data subject.

Processing of Personal Data

Personal data can be defined as any information that allows a natural person to be identified, directly or indirectly. You can provide us with your personal data in the context of the following activities, for the corresponding purposes and based on the stated grounds:

Newsletter: By subscribing to our newsletter, you provide your email address. Our website collects these data based on your consent and for the purpose of sending you relevant information and updates.

Website analytics: By accepting the cookies on the website, you consent to WFNS processing your IP address, country and behavioural data.

Other purposes: We may sometimes need to process personal data to comply with its legal obligations.
WFNS treats your personal data as confidential and commits to process it only in a way that is compatible with the purposes for which the data were initially collected.

Your Rights as a Data Subject

At all times, the data subject has the possibility to exercise his or her rights as described in the General Data Protection Regulation. The data subject can exercise the following rights:

Right of Access
You have the right at any time and free of charge to access your personal data and to request a copy of the personal data that WFNS collects about you.

Right to Rectification
You always have the right to have incorrect personal data corrected, or incomplete personal data completed.

Right to Erasure (“right to be forgotten”)
You can request to have your personal data erased from WFNS’s systems.

The request to erase your personal data cannot always be granted due to contractual or legal obligations. WFNS will take these obligations into account when replying to your request.

Right to Object
You have the right to object to the processing of your personal data if the processing takes place on the ground of the legitimate interest of WFNS or on the ground of the public interest. We will stop processing unless we can prove that there are compelling legitimate grounds for the processing or for the exercise of legal claims. You can also object in the case of direct marketing, so the personal data will no longer be processed for these purposes.

Right to Withdraw Consent
For the processing of your personal data collected by WFNS with your consent, you can withdraw your consent at any time. For example, you can always unsubscribe from the newsletters. However, the withdrawal of your consent does not apply to processing previously carried out by WFNS.

Right to Restriction of Processing
In certain cases, the data subject is entitled to obtain the restriction of the processing of his or her personal data. We will continue to store your data, but we will restrict its use. You can e.g. submit this request when you think that your personal data is inaccurate, or the processing by WFNS is unjustified. We only have to grant these requests in specific cases as defined by law.

Right to Data Portability
The data subject has the right to receive the personal data concerning him or her, processed by WFNS, in a structured, commonly used and machine-readable format and/or to transmit those data to another controller.

These rights can be exercised free of charge by sending an e-mail to We commit to answer your request within one month upon its receipt. It is possible that we request additional information first in order to confirm your identity and ensure the request originates from you.

Right to Lodge a Complaint
If, at any time, you believe that WFNS infringes your privacy, you have the right to lodge a complaint with the competent Supervisory Authority.

Disclosure to Third Parties
WFNS will refrain from disclosing or selling personal data of data subjects to third parties as well as publicly disclosing data subjects’ personal data, unless in the following specific cases:

• Personal data can be shared with third party service providers to which WFNS outsourced certain processing activities. In any case, they are limited to processing your personal data in accordance with our instructions. WFNS will conclude data processing agreement with such processors so they are obliged to comply with all obligations required by the applicable data protection legislation.

• If it is required by applicable laws or regulations.
