Handling operators must comply with these requests unless there is a possibility that the disclosure could harm the data subject’s or a third party’s life, body, property or other rights or interests, or that it could seriously interfere with the handling operator’s business (Article 33).

The handling operator must investigate without delay and, based on the results of the investigation, comply with these requests to the extent necessary to achieve the purposes of use of the retained personal data (Article 34). Furthermore, data subjects may request that handling operators discontinue the use of or erase retained personal data and stop providing retained personal data to third parties if: • the data was or is being acquired, processed or provided to a third party in violation of the APPI;

measures regarding personal data: • the name of the handling operator;
