Privacy

This site is run by me, Chongbo Ning. It uses no cookies.

What I record. The pages you visit, the skills you pick, what you type or paste into the printer, which cards print, and how long they stay on screen. Your IP address is used to count visits and is not kept.

Who handles it. PostHog stores the visit data in the EU. What you type is also sent to Anthropic in the US, so that Claude can choose the cards.

Why. To see which work people look for and improve the site. The legal basis is my legitimate interest in understanding how it is used.

How long. 30 days.

Your rights. Email me at ningchongbo2000@gmail.com to see or delete what I hold, or to object to it being recorded. You can also complain to the Information Commissioner's Office at ico.org.uk (opens in a new tab).
