If you do not want to participate in this survey or in any other surveys that might follow,
reply to the email and tell us that you want to opt out. You can also only write the word optout in your reply.
If you want to have all your personal data deleted from the Paessler systems in accordance with data protection laws, contact the Paessler Data Protection Officer in a separate email to privacy@paessler.com and ask them to delete all your personal data.
