One of the legal grounds for lawful processing of personal data is the implementation of the data controller or a third party's legitimate interests. To determine when a legitimate interest is justified, a so-called balance test is done to weigh controller or a third party interest against the basic rights of the data subject.
When our processing based on a legitimate interest, we document the implementation of the balancing test and its results so that, if necessary, we can demonstrate that our operations comply with applicable data protection framework.
