About this update from 1&1 Ag
Information on data protection for shareholders 1&1 AG as the controller processes shareholders' personal data (surname and first name, address, email address, number of shares, class of shares, type of ownership of the shares and number of the admission ticket with access code and password to the AGM-Portal) as well as personal data of the shareholders' representatives, if applicable, for the purposes of the general meeting in accordance with applicable data protection laws. Purposes and legal grounds The processing of personal data is legally mandatory for the proper preparation and conduct of the general meeting, for the exercise of shareholders' voting rights. The legal grounds for the processing are found in point (c) of Art. 6 (1) first sentence GDPR in conjunction with Sections 118 et seqq. AktG. Furthermore, data processing that is useful for the organisation of the general meeting may be carried out on the grounds of overriding legitimate interests (point (f) of Art. 6 (1) first sentence GDPR). Insofar as shareholders do not provide their personal data themselves, 1&1 AG generally obtains these data from the shareholder's custodian bank. Transfer of data We also engage external service providers and group-affiliated companies to conduct our general meeting. These entities receive solely the personal data that are necessary for the performance of the engagement from the Company and the custodian banks. Insofar as they process your personal data, they are acting on our behalf as contracted processors in accordance with the provisions of Article 28 GDPR. The service providers engaged by the Company for the organisation of the general meeting process the personal data of the shareholders and shareholder representatives exclusively in accordance with the instructions of 1&1 AG and solely to the extent that this is necessary for the performance of the contracted service. All employees of the Company and the employees of the engaged service providers who have access to and/or process personal data of the shareholders or shareholder representatives are obligated to treat such data confidentially. In addition, personal data of shareholders or shareholder representatives who exercise their voting rights may be viewed by other shareholders and shareholder representatives within the scope of the statutory provisions (in particular the list of participants, Section 129 AktG, insofar as the shareholders or shareholder representatives are listed there). Duration of storage 1&1 AG deletes the personal data of shareholders and shareholder representatives in accordance with the statutory regulations, in particular if the personal data are no longer necessary for the original purposes of the collection or processing, the data are no longer needed in connection with any administrative or legal proceedings and there are no statutory retention obligations. Rights of the data subject Shareholders or shareholder representatives satisfying the legal prerequisites have the right to obtain information about their processed personal data and to request the rectification or erasure of their personal data or the restriction of processing. In addition, shareholders or shareholder representatives have the right to lodge a complaint with supervisory authorities. If personal data are processed on the basis of point (f) of Art. 6 (1) first sentence GDPR, shareholders or shareholder representatives shall also have a right of objection in accordance with the statutory prerequisites.
