Storage limitation

Data should in principle be kept for no longer than is necessary for the purposes for which the personal data is processed.

According to Article 19 of the APPI, PIHBOs are required to "strive […] to delete the personal data without delay when such utilisation has become unnecessary". That provision needs to be read in conjunction with Article 16(1) of the APPI prohibiting the handling of personal information beyond "the necessary scope to achieve a utilisation purpose". Once the utilisation purpose has been achieved, processing of personal information cannot be considered necessary anymore and, hence, cannot continue (unless the PIHBO obtains the data subject's consent to do so).
