Privacy notice

Last updated: October 10, 2026

We don't sell personal data, and there is no third-party advertising on this site.

What we collect

• Sign-in details. When you sign in, what is needed to do that and to keep you signed in securely, such as the e-mail address a sign-in code is sent to, and when, in which browser and from which network address a code was requested.
• Usage information. The pages and features you use and how the site responds (for example how fast pages load and whether errors occur). We use it to improve the service.
• Device information. What your browser reports about itself and the device it runs on, without being asked and without any prompt: the browser and its version, the operating system and its version, the processor type, the screen and window size and colour settings, the language, the time zone, the connection type, how much memory and how many processor cores are available, the graphics hardware and the fonts installed, display preferences such as dark mode or reduced motion, whether cookies and browser storage work, and the page that linked you here.
• Approximate location and network. Your country, and where available your region, city and postcode, together with how wide an area that estimate covers; also the network operator your connection belongs to, and whether that network looks like a VPN, a proxy or a data centre. This is worked out from your network connection, with the help of location lookup services we pay for; we send them only the network address, never your name and nothing you do on the site. Our usage records keep the approximate location and the network, never the address itself and never map coordinates.
• We approximate some known identifiers to tell real visitors from automated traffic and to measure how the service is used.
• Messages you send us. If you use the Feedback button, your name, your message, the page you were on and any screenshot you add are delivered to our team's private channel on Discord, the chat service we use.
• Cookies and similar browser storage. This site's own cookies and storage keep you signed in, protect the site from automated traffic, remember your preferences (such as the colour theme) and measure usage, including recognising a browser that has visited before. One of them is a random id this site keeps in a cookie, in the browser's local storage and in its own small database, so the same browser is still recognised when one of those is cleared; clearing this site's data in your browser resets it. They are set by this site only.

We never ask your browser for permission to anything, and nothing here uses your camera, microphone, precise location, notifications or clipboard.

How we use it

Only to run, secure and improve this service. We don't sell or rent personal data, we don't share it with advertisers, and the site shows no third-party ads. The location lookup services are suppliers we use to answer one question; all we send them is a network address, with nothing that identifies you and nothing about what you did here.

How long we keep it

• Usage information (including the device and network information above): 45 days, then deleted automatically.
• Location lookups: the answer for one network address is kept for up to 30 days, so one visitor costs one lookup.
• Sign-in: a sign-in lasts up to 12 hours and ends after 2 hours without use. If you choose "Keep me signed in", that browser stays signed in for up to 30 days after you last use it, and 180 days at most.
• Returning-visitor cookie: up to one year in your browser; our record of it is removed once it would have expired.
• Feedback messages: kept in our team channel until we delete them.

Questions, or deleting your data

To ask what we hold about you, or to have it deleted, send us a note with the Feedback button on the right-hand side of any page of the dashboard. Tell us roughly when you used the site so we can find the right records, and we will reply.

You can also clear this site's cookies and stored data in your browser settings at any time.
