Clients are subject to further information and rights and will be addressed directly.  Log Files My contractor and Webhost (1&1) saves log information while you visit this website. The log files cannot be deleted manually and contain - IP address,- date and time of visit,- Uniform Resource Locator (URL) you called in order to visit,- Uniform Resource Locator (URL) you call in order to leave, and- browser information in anonymised form for a period of only 21 days; the information is not subject to transfer to third parties or countries outside the EU. Log files are of technical importance. The Webhost stores log file data in order to monitor network functionality and understand and solve technical problems. The Webhost also produces statistics for these reasons and therefore may claim a legitimate interest. Technically, I am able to access the log files. However, I do not make any use of the information stored therein, I do not store log information on my devices and do not pass them on to third parties, either. If you disagree with log information storage please exit the website(s). Cookies & Co. Cookies, fingerprinting technologies, tracking and identification tools such as Google Analytics, Adwords etc. are not applied.  Links to other websites This privacy statement does not cover other websites which are linked to this website. Social Media buttons on this websites are simple graphics manually linked to the respective profiles.  Newsletter and contact forms There are no newsletters or contact forms with third parties involved.  First contact If you wish to get in touch you may choose to send a simple or encrypted e-mail - it depends on your idea of secrecy. You may prefer to call me directly on the phone. In case I cannot answer, my team will offer you to leave a message for me to call you back. If you wish so. If you don't, no information will be gathered and send. You may always try to call again. Mails will be deleted after I called you back or other reason of completion occurs. If you wish to get in touch via social media, I expect you to know about the respective privacy terms. If possible, I link my profile with the respective terms. I do have to warn though, that social media is not the right media to write confidential information. My profiles exist for information purposes only. That is also why I do not use statistics like Facebook Insights offers. As long as I cannot turn them off, I have to look away and refer to Facebooks privacy terms.  Your rights Of course, I will send you the necessary information above if you ask for it via info(at) Deletion happens after 21 days when it comes to log files, right after completion (e.g. contact) and I will delete social media profiles when necessary, but not because of paranoia.
