Dear sir or madam,
according to the German Privacy Law (BDSG § 34, https://www.gesetze-im-internet.de/bdsg_1990/__34.html) I ask you to provide me with the following information:
* all data stored by your company that is in any way related to my person
* how you obtained this data
* for what purposes you were using this data
* to which other organizations you forwarded the data
By law you are obliged to provide this information on demand once per year. If you do not comply, a German Privacy Protection Agency will be involved. You are free to send this information to me via e-mail or other viable means. Please note that this e-mail has to be transmitted via a secure connection. I suggest to use GPG.
Best regards
