The following provisions to describe the type, scope and purpose of collecting, processing and utilizing individual data. This data privacy policy applies only to my web sites and pages. If links on my sites and pages route you to other pages, please inquire there about how your data are handled in such cases. Some of them might not follow the German/European (EU) data privacy standards and/or host data outside of the European Union (EU). I host all data in Germany and the United Kingdom.

Information about cookies

  1. To optimize my web presence, I use cookies on some of the pages (especially on the WordPress based Blog). These are small text files stored in your computer’s main memory. These cookies are deleted after you close the browser. Other cookies remain on your computer (aka long-term cookies) and permit its recognition on your next visit. This allows us to improve your access to my sites or pages.
  2. You can prevent storage of cookies by choosing a “disable cookies” option in your browser settings. However, this might limit the functionality of my Internet sites or pages as a possible result.


To increase the performance and protect my Sites and pages, I use the CDN (Content Delivery Network) of CloudFlare Inc. for some of them. CloudFlare cache content and collect access data. They use distributed infrastructure, and the next/fastest servers might be outside of the European Union (EU). Based on the information CloudFlare published, they keep the collected raw data for four hours (max for three days) before they delete them. There is some information available about how and what CloudFlare collects and stores. And here is a link to the CloudFlareSecurity Policy.


To provide a secure but convenient way to contact me, I decided to use FORMSPREE as a Service. FORMSPREE is a community driven service. You can take a look at the GitHubpage of FORMSPREE to find out more about the guys behind the service. According to the FORMSPREE page, they just store 100 form submissions. FORMSPREE uses servers who might be outside of the European Union (EU).


I do not use SendGrid directly, but my Forms Service FORMSPREE does to transfer mails from the contact form I use. So I use them indirectly. So you should take a look at the SendGrid Privacy PolicySendGrid use servers who might be outside of the European Union (EU). SendGrid promises to respect Safe Harbor Principles for all data received from the European Union (EU).


My pages, sites, and services are not directed to children under 13 years of age. All pages, sites, and services are publicly available and none should contain adult content. Nevertheless, the legal situation for persons under 13 (Even under 18, to be honest) is much more complicated. So I decided to set the minimum age to 13, even if younger visitors should be OK.


According to the Federal Data Protection Act, you have a right to free-of-charge information about your stored data, and possibly entitlement to correction, blocking or deletion of such data. Inquiries can be directed to the following e-mail addresses: 


Social Media

If not otherwise noticed, the impress applies to all my social media profiles. In minimum to the following:[email protected]/

The impress applies to the complete content of profile and not only to the URLs above. This impress will as well apply to all other profiles that I generated on all other (unlisted above?) services and/or networks. It will not apply to generated profiles of me; some services establish profiles by crawling the web for info without my knowledge and/or permission.

It applies only to the content I provide on the social networks/social media services (like texts, source code, pictures, or contact informations). I’m not responsible for the web site or the service itself and/or the functionality! Only the owner/service provider of the network/service is responsible for that.

Domains covered

If not noticed otherwise, my impress and privacy statement applies to all my sub- and sibling sites. In minimum to the following domains (including all sub-domains):

Domains excluded

My impress and privacy statement doesn’t apply to the following:

There are technical reasons for that. It might be a 3rd party service that I use via a DNS cname entry or other.

Other data usage

I heavily use cloud services to store or transfer all kinds of data. Whenever possible I use encryption to protect personal or private data whenever I store or even transfer them via cloud services. Mostly, this protection is based on EncFS (Encrypted File System) or PGP. Most cloud service providers use servers outside of the European Union (EU).

An exception is the iCloud service from Apple: I really use a lot of Apple equipment, equipment that uses the iCloud service from Apple to store nearly everything (e.g. Text Messages, Call Logs and many other things). Apple promises that this data is saved securely and protected against others, but there is no way really proof that or to enforce any kind encryption from my end. Even so, I personally trust Apple here! Apple use servers outside of the European Union (EU).

The mail service of my domains is mostly hosted by Microsoft in Europe as part of their Office 365 (e.g. Exchange Online) services! I also use Microsoft Office 365 and some other Microsoft Azure services to save and sync calendar/contact infos across my devices and to transfer/save/store other data. The transfer is always encrypted but at the moment, there is no way to enforce an encryption of the data when they are stored in the data centers of Microsoft. Microsoft also uses servers outside of the European Union (EU).

I use a lot (!!!) of different mobile devices, most of the time they are based on iOS or Android. However, I also use a lot of other devices to test them. Trust me, I really spend a lot of time to configure all of them as secure as possible, but there is no guaranty that someone like the vendor (via call home), a carrier or any other service provider doesn’t get access to any personal data from these devices! Many vendors use servers outside of the European Union (EU).

All of my IT (mobile and desktops) systems and mobile devices are configured as secure as possible. All Data (even all my backups) are stored encrypted via Apple FileVault or EncFS (Encrypted File Fystem) whenever this is technically possible.

never safe any NDA (Non-disclosure agreement) protected content on cloud services or file servers controlled by others without encryption and the permission to do so!
