To accomplish this right, you need to submit a written request to the controller that you think processes your personal data and where you will specify in detail the data that you want to know about.
The controller has a deadline of 30 days after the submission of the written request to notify you about:
If you re-submit the same or similar request for access to your personal data and no change has occurred in the meantime, the controller (the authority) is not obliged to answer.
There is an exception to this rule when more than six months have passed since the day of submitting the previous request.
Also, when personal data is processed solely for scientific research or statistical purposes, the controller is not obliged to act on the request.
