Privacy

What this site runs, what it records, and the choice you get to make about it — in plain sentences.

Always on: aggregate counts

Umamicounts pageviews and copy events — no cookies, no fingerprinting, no personal identifiers, no cross-site anything. It is how we know whether anyone uses this reference at all. It runs for every visitor, and both its script and the counts it sends go through this domain rather than the vendor's, so blocklists that cut the vendor's domain don't skew the only counts we keep. Fetches of the plain-text files (the .md mirrors, llms.txt) and any non-browser request for a page are counted on the server the same way: a URL and a user-agent class. For requests that aren't from a browser, a truncated copy of the user-agent string the agent sends is kept too — that is how a new crawler gets recognized. Nothing else.

Optional: product analytics and session replay

Mixpanel(event analytics) andMicrosoft Clarity(session replay) record how the site is used in enough detail to count as personal data, so they are optional:

• In the EU/EEA, the UK, and Switzerland they load only after you allow them from the banner.
• Everywhere else they load by default — you can turn them off below.
• If your browser sendsGlobal Privacy Control, they stay off and we don't ask.

What this site keeps on your device

One cookie and four values in your browser's local storage. None of them is an identifier, none is sent to anyone else, and nothing here follows you to other sites.

• The cookie is nk-geo, and it holds one word — gated or open — for a day. The server works out from your connection whether the banner applies in your region and writes down which rule won, so the page doesn't have to ship a location lookup to your browser. Being a cookie it travels along with later requests, though nothing on the server reads it back. It records the rule, not where you are.
• nk-consent is your answer about the optional analytics — the two buttons below write it and clear it.
• nk-theme, nk-mode-override, and nk-snippet-framework remember your dark-mode choice, whether the reference shows live or simulated keyboards, and which framework tab you last copied from.

What we never collect

No accounts, no names, no ads, no selling or sharing of data. The waitlist stores exactly the email you type into it, for exactly one send. Our success metric is copy events — whether the markup was useful enough to take — not how long you stayed.

Change your mind

Both controls apply immediately and reload the page.

Reset clears your stored choice; in regions with the banner it will ask again, elsewhere the defaults return.
