Guidelines 1/2020 on processing personal data in the context of connected vehicles and mobility related applications
Paragraph 3.2.3 Retention period
134. EU regulation 2015/758 of 29 April 2015 stipulates that data shall not be retained for longer than is needed for processing emergency situations. Those data shall be completely deleted when they are no longer needed for that purpose. Furthermore, in the internal memory of the eCall system, data shall be automatically and constantly deleted. Only the vehicle’s last three positions can be stored, insofar as it is strictly necessary to specify the current position of the vehicle and the direction of travel at the time of the event.
