What we collect, and why

We count visits with PostHog, an analytics service: which pages are viewed, the page you arrived from, and your browser and device type. To tell one visit from the next, it stores a random identifier in your browser. We use this to see which pages are useful and what people search for that we do not cover yet. It is not used for advertising and is not sold.

If a page breaks, an error report goes to Sentry: the page address, your browser and device type, and the technical details of the error. It does not include anything you typed into a form.

Like any website, the services that deliver these pages see your IP address when your browser asks for them. We use it to stop abuse — for example, limiting how many messages one address can send in a minute — and that limit is held in memory for about a minute. It is not stored with your message.

The contact form stores what you write, the kind of message, the page it is about if you came from one, your browser type, the time, and your email address only if you give one. The email address is used to reply to you and for nothing else. It is never shown on the site or added to any list.

Messages are read by the person who runs the site. They are kept while they are being dealt with and deleted within twelve months of being closed. Junk is deleted sooner.

The site runs on Vercel (the pages) and Railway (the server behind them), with its data held by Supabase. Analytics go to PostHog and error reports to Sentry. Each processes data only to provide that service. Nothing is sold or shared with anyone else.

You can read everything without giving us anything. You can send a message without an email address. Browser privacy settings and content blockers that stop analytics will not break the site.

To have a message you sent deleted, or to ask what we hold, use the contact form and quote your message number if you have it.
