Privacy

The short version: this site keeps a count of which pages get read, a rough sense of what city readers are in, and a random number in your browser so it can tell a returning reader from a new one. It does not keep your IP address, does not use tracking cookies, and does not sell or share any of it.

// WHAT IS STORED, AND WHERE

Page counts — on our server
Each page view increments a counter for that path and that day. Only paths this site actually publishes are counted. Daily rows are kept for about three months.
City and country — in aggregate, on our server
Our host derives an approximate region — Auckland, Canterbury — from the network your request arrives on. We count it (“Auckland: 12”) and nothing else. It is stored in a separate tally from everything about visitors, so it cannot be traced back to say where any particular reader is.
A visitor id — in your browser, hashed on our server
The first time you arrive, your browser generates a random number and keeps it in its own local storage. It is not a cookie, contains nothing about you or your device, and is not shared with anyone. When a page view is recorded we send that number, and the server stores only a salted hash of it — so the value we hold is not the value you could read in your own browser. It lets us tell that someone came back. It is forgotten after six months, and clearing your site data ends it immediately.
Your drill answers — only in your browser
The record of which drills you have worked, and what you chose, is kept in your browser alone. It is never sent to us. You can clear it from the archive page.
Your email — only if you give it to us
Subscribing sends your address to our newsletter provider so we can send you drills. We record which page you subscribed from. Every email carries an unsubscribe link.

// WHAT IS NOT STORED

  • Your IP address. It is used in the moment to work out a rough city, then discarded — never written down.
  • Tracking cookies, advertising identifiers, or device fingerprints of any kind.
  • Any link between where you are and who you are — those are two separate tallies by design.
  • Anything at all about what you read, tied to your name or email.

// OTHERS INVOLVED

The site is hosted by Vercel, which keeps its own server logs, and uses Vercel Analytics for cookieless page statistics. Newsletter subscriptions are handled by beehiiv. Paid products are sold through Gumroad, which handles payment and holds purchase records — this site never sees your card details.

// ASKING US TO FORGET YOU

Clearing this site's data in your browser removes the visitor id and your drill record, and there is no way for us to reconstruct either. For anything else — a newsletter address, a question about what is held — write to hello@bankingjudgmentlab.com.
