According to Art. 15 GDPR, you have the right at all time, to be informed whether there are stored personal data available about you. If so, you have furthermore the right to have wrong data corrected (Art. 16 GDPR) and its deletion by request (“right to be forgotten”, Art. 17 GDPR).
Line of action
Please understand that before we will take any action about information, correction or deletion, we have to verificate your identity in order to prevent data from falling into the wrong hands. To prepare a complete record of your data, I’ll need your full name and the email address(es) used for interaction.
The identity check can be done by a suitable proof (ID card copy) or by the confirmation of your e-mail address. A copy of the ID card is only necessary if e.g. the requesting e-mail address does not match what I have stored with me or if there is any suspicion that the person requesting is not the same for whom the data provision is intended.
