The only thing I collect is the number of download on a launchpad project,
I do not store your IP, your browser, or anything that can be used to track you,
for me, you're anonymous.
I don't even use ads.
I use the youtube-nocookie.com links and reCaptcha (contact page) on my website, but we never know if google is collecting you data anyway, so be careful.
The only cookie I set is for the language (in the header) and is used for display purpose only, nothing is collected or saved, clear your browser's cookies and it will be gone, forever (and a day).
