Privacy
What this site measures, why, and the honest answer - almost nothing, and only if you say yes.
The honest version first: I do not want your data. I want to know which pages get read, so I write more of those. That is the entire scheme. Nothing here is sold, profiled, retargeted or whispered to an ad network - the numbers are used for developing this site and for my own research into what is worth building next.
The version below is the same thing, said the way the law asks it to be said. It applies the GDPR - in Poland, RODO - because that is where I live and because you have rights here whether or not I find paperwork fun.
Who is responsible
Me - Adam Jurek, the one person behind this site. The contact page lists the channels that actually reach me; any of them works for anything on this page.
What is measured, and only if you said yes
Nothing is counted until you press Allow on the consent bar. Declining is not a negotiation - it is silence, permanently, until you change your mind.
If you did say yes, the site records page views - which page, when, what it was referred from, and rough facts about the browser and device - and reports of JavaScript errors the site throws in your browser, so I can fix them. The legal basis is your consent (art. 6(1)(a) GDPR), and you can withdraw it at any time - the cookies page says how, and withdrawing is as easy as agreeing was.
The counting is done by PostHog, running on their EU cloud, acting as a processor. Events go to their servers in the European Union and stay there.
What is collected without asking
The server that delivers these pages - hosted on Railway - keeps ordinary access logs for a short time: IP address, requested URL, timestamp. Every web server on earth does this; it is how problems get found and abuse gets stopped. The legal basis is legitimate interest (art. 6(1)(f) GDPR) in keeping the site running, and the logs are not used for anything else.
How long
Analytics events are kept for at most twelve months and then deleted. Server logs rotate away much sooner. There is no archive of you here.
Your rights
All of them, the full GDPR set: access, rectification, erasure, restriction, portability, and objection. Withdrawing consent never affects what happened before you withdrew it - it just stops the counting from then on.
If you believe I have handled your data badly, you can complain to your supervisory authority - in Poland that is the President of the Personal Data Protection Office (UODO, uodo.gov.pl). I would appreciate hearing about it first, because whatever it is, it is almost certainly a mistake rather than a scheme.
What this site will never do
The short list
No ads. No selling data. No cross-site tracking. No fingerprinting. No newsletters you did not ask for. No dark patterns on the consent bar - the no button is exactly as big as the yes button, on purpose.
