We didn't find deletion information, unfortunately. Generally it seems Conrad takes privacy very seriously. Our advice is to send them an email requesting deletion. Obviously, you should do this from the mail address known at Conrad (linked to your account).
If you're in Germany, you could use this form: https://www.conrad.de/ce/de/ContactSend.html
In The Netherlands, you could use this form: https://www.conrad-electronic.nl/infocenter/contact.php
Otherwise, search on your local Conrad site for contact information, or try email@example.com.
Because an account at Conrad cannot be deleted, we suggest to make your data useless.
Be logged in on the site, then go to Profile Settings (Or Options, etc.). In all fields with personal data (such as name, address, city), fill in AccountKiller, if possible. If you can only choose from several options, change the value. If possible, use a homepage/URL field or long text field (such as Description) and put this line in it: http://www.accountkiller.com/removal-requested. This may incite webmasters to add an account deletion option.
If you can't find any contact info and still wish to ask something, for example a question about what exactly is deleted, about data retention, etc., you may contact the domain owners using this info.
If you signed up for Conrad using a third-party login such as Facebook or Twitter, you probably want to revoke all access from Conrad. Click the icon below to find out how.
