What personal data I collect and why I am collecting it.

I’m not interested on any personal data. However, I can collect some data for services like statistics and comments to improve the overall user experience. I am not interested in selling your data to any third party company. You can find more information about data collection in the following text.


When visitors leave comments on the site I collect the data shown in the comments form, and also the visitor’s IP address and browser user agent string to help spam detection.

An anonymized string created from your email address (also called a hash) may be provided to the Gravatar service to see if you are using it. The Gravatar service privacy policy is available here: After approval of your comment, your profile picture is visible to the public in the context of your comment.

I collect information about visitors who comment on Sites that use our Akismet anti-spam service. The information I collect depends on how the User sets up Akismet for the Site, but typically includes the commenter’s IP address, user agent, referrer, and Site URL (along with other information directly provided by the commenter such as their name, username, email address, and the comment itself).


If you upload images to the website, you should avoid uploading images with embedded location data (EXIF GPS) included. Visitors to the website can download and extract any location data from images on the website.

Contact forms.

I have a couple of forms on my page so you are able to contact me. If you use one of the forms on my page I will use the data provided to answer your question or take your feedback. After your request is handled, I archive the contact request in my messaging system so I can refer later to this conversation. However, I will not use your information to send you any information you haven’t requested and I do not share this information with third parties.

Facebook Social Plugins.

My website uses social plug-ins, which are created and operated by the social network Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304, USA (“Facebook”). The plug-ins show the Facebook logo. When you open a page on My website containing a social plug-in, your browser establishes a direct connection to the servers operated by Facebook. The content of the plug-in is transferred from Facebook directly to your browser and integrated into the web page. Through integration of the plug-in, Facebook receives information that you have accessed the corresponding page on my website. If you are logged into Facebook, Facebook can associate the visit with your Facebook account. If you interact with plug-ins by using the “Like” button or submitting comments, for example, the information is sent from your browser directly to Facebook and stored there.

All users can see, edit, or delete their personal information at any time (except they cannot change their username). Website administrators can also see and edit that information.

You can also request that I erase any personal data I hold about you. This does not include any data I am obliged to keep for administrative, legal, or security purposes.
