Privacy Policy

Thank you for visiting This privacy policy tells you how I use personal information collected here. Please read this privacy policy before using the site or submitting any personal information. By using the site, you accept the practices described in this privacy policy.


Most webpages here do not use any cookies (but third party services used by the website, such as Disqus for comments, may use their own cookies to fulfil your specific requests). Some pages may set tracking cookies to gather anonymous statistical data about how my visitors use the website, which allows me to improve the layout of this website.

Amazon Associates Program

This website is a participant in the Amazon Services LLC Associates Program. This means, in particular, that if you follow a link to or any other national version of Amazon website and then make a purchase within 24 hours, I will receive a small percentage of what you pay to Amazon (but your price will stay exactly the same).

I, however, never link to specific products just in order to advertize them. I link only to the products that I genuinely find helpful (usually books I have written; it would be a shame if I didn’t find those helpful), and the webpages linking to such products express my honest opinion on the products. In other words, I never recommend a product just in order to persuade you to buy it; I recommend it because I myself find it useful.

Collection of Information

I can collect personally identifiable information, like names, postal addresses, email addresses, etc., when voluntarily submitted by my visitors. This information is only used to fulfil your specific request, unless you give me permission to use it in another manner. I never share any information with third parties, unless required by the law.
