We use one thing.

The one thing we use.

localStorage["theme"] — this stores your preference between light mode and dark mode. When you click the sun-or-moon toggle in the navbar, we save your choice to this key on your own device. Next time you visit, we read it and apply your preferred theme without flashing the wrong one on load.

This data is stored exclusively in your browser, on your device. It never leaves your machine. There is no server to receive it, because we did not build one for this site.

Technically, localStorage is not a cookie — it is a separate browser-storage API. We are listing it here anyway because most people think of "what does this site save on my device" as "cookies," and we want to be honest about what is being saved.

What we don't use.

• No first-party tracking cookies.
• No third-party advertising cookies.
• No analytics cookies (no Google Analytics, no Plausible, no Fathom, no Mixpanel, no PostHog).
• No session cookies (there are no sessions to track).
• No authentication cookies (there is no authentication).
• No re-targeting pixels.
• No fingerprinting scripts.
• No A/B testing tools.
• No consent-banner vendor cookie (you may have noticed the absence of a consent banner — that is the reason).

How to clear the one thing.

Open your browser's DevTools, go to Application (Chrome) or Storage (Firefox), find Local Storage, click the entry for this site's URL, and delete the theme key. Or wipe site data through your browser's privacy settings. Either way, the site continues to work — it just defaults to whichever color scheme your operating system prefers.

If we ever changed this.

If we add a new key to localStorage, or if we ever introduce a real cookie, we will update this page first and the rest of the site after. The list above is meant to stay accurate — if it ever stops being accurate, that is a bug.
