Cookie Policy

A cookie is a small piece of data that a website asks your browser to store and then sends back to a server on future visits. Cookies are commonly used for logins, shopping carts, analytics, and advertising. Hardware Math uses none of these mechanisms and sets no cookies of any kind.

This is possible because of how the site is built. Hardware Math is a fully static website hosted on Cloudflare Pages. There is no server-side code, no backend, no database, and no user accounts. There is nothing to log you into and nothing that needs to remember you between visits, so there is no reason for us to set a cookie.

• No advertising cookies.
• No analytics cookies.
• No tracking or profiling cookies.
• No session or login cookies.
• No third-party cookies of any kind.

The single piece of information the site keeps on your device is your chosen light/dark theme. When you switch between light and dark mode, your browser records that choice using localStorage so the site can show you the same theme the next time you visit.

localStorage is a standard browser storage feature. It is not a cookie: it is never automatically attached to network requests, and it is not transmitted to a server the way cookies are. In our case it holds exactly one value: your theme preference. That is the entire extent of client-side storage on this site.

• What is stored: a single value indicating light or dark theme.
• Where it is stored: your own browser, on your own device.
• Where it is sent: nowhere. It never leaves your device and is never transmitted to us or to anyone else.
• What it is used for: functional display only, so the site remembers your preferred appearance.

Storing a theme preference is a functional (essential) convenience. It does not identify you, it does not follow you across websites, and it is not linked to any account, profile, or analytics record, because none of those things exist here.

Because Hardware Math is static and has no backend, we have no technical means to read this value from our side even if we wanted to. It lives entirely in your browser and is only read by the site's own code running locally in your browser to decide which theme to display.

You are always in control of this value. If you clear your browser's site data, use private/incognito mode, or otherwise wipe localStorage for this site, your saved theme preference is simply forgotten.

Nothing breaks. The next time you load the site, the theme resets to the default, which follows your system or browser light/dark preference. You can switch it again at any time, and the site will store your new choice the same way.

Cookie-consent banners exist because sites that set non-essential cookies, or that run analytics and advertising trackers, are generally required to ask for your permission first. Hardware Math does none of those things.

Because we set no cookies and perform no tracking, there is nothing to consent to, so we do not show a cookie-consent banner. We would rather tell you plainly on this page what we do than interrupt you with a pop-up that asks permission for tracking we do not actually do.

Some sites appear cookie-free but still load third-party code (analytics, fonts, ad networks, social widgets, embedded videos) that can set cookies or track you on the site owner's behalf. Hardware Math does not do this.

• No analytics services.
• No advertising or ad-network scripts.
• No third-party trackers or tag managers.
• No third-party fonts, images, or embeds.
• No social media widgets or share pixels.

Everything the site loads is first-party and static. There is no third party in a position to set a cookie or track you through this site.

Hardware Math does not currently plan to add analytics or advertising. But if that ever changes, we will not do it quietly.

If we ever introduce analytics, advertising, or any technology that sets cookies or tracks visitors, we will add an appropriate consent mechanism and update this Cookie Policy to describe exactly what is used and why. We will make those changes and give you the ability to make a choice before any such tracking begins, not after.

If you have questions about this policy, you can reach the site owner at simon.agentinfra@gmail.com.

This Cookie Policy was last updated on 2026-07-07. If we make material changes, we will update this page and revise the date above. For anything requiring a specific legal entity or governing jurisdiction, [jurisdiction to be specified by the site owner] applies once completed by the owner.
