As a data subject, you have the following rights vis-à-vis BMW under the GDPR:
Right to know (Art. 15 GDPR):
You may at any time request information from us about the data we hold about you. This information concerns, among other things, the categories of data we process, the purposes for which we process them, the origin of the data if we have not collected it directly from you and, if applicable, the recipients to whom we have transmitted your data. You can obtain a copy of your personal data from us free of charge. If you request additional copies, we reserve the right to charge you for the additional copies.
Right to rectification (Art. 16 GDPR):
You can request that we correct your data. We will take reasonable steps to keep the information we hold and process about you accurate, complete and up to date, based on the most recent information available to us.
Right to deletion (Art. 17 GDPR):
You can ask us to delete your data if the legal requirements are met. According to Art. 17 GDPR, this may be the case, for example, if
the data is no longer necessary for the purposes for which it was collected or otherwise processed;
you withdraw your consent that is the basis for the data processing and there is no other legal basis for the processing;
you object to the processing of your data and there are no overriding legitimate grounds for the processing, or you object to the processing of your data for direct marketing purposes;
the data has been processed unlawfully, unless the processing is necessary,
to ensure compliance with a legal obligation that requires us to process your data;
in particular with regard to statutory retention periods;
to assert, exercise or defend legal claims.
Right to restrict processing (Art. 18 GDPR):
You can request that we restrict the processing of your data if
you contest the accuracy of the data, for the period of time we need to verify the accuracy of the data;
the processing is unlawful and you object to the deletion of your data and request the restriction of their use instead;
we no longer need your data, but you need it to assert, exercise or defend legal claims;
you have objected to processing pending the verification whether our legitimate grounds override yours.
Right to data portability (Art. 20 GDPR):
At your request, we will transfer your data to another controller, insofar as this is technically possible. However, you are only entitled to this right if the data processing is based on your consent or is necessary to fulfil a contract. Instead of receiving a copy of your data, you can also ask us to transfer the data directly to another controller specified by you.
Right to object (Art. 21 GDPR):
You may object to the processing of your data at any time for reasons relating to your particular situation, provided that the data processing is based on your consent or on our or a third party's legitimate interests. In this case, we will no longer process your data. This does not apply if we can demonstrate compelling legitimate grounds for the processing which override your interests, or if we need your data for the establishment, exercise or defence of legal claims.
