Is My Best Score Saved Privately?
Yes — and here is exactly where that number actually lives.
Short answer: yes, and it never leaves your browser
Your best distance is stored using a browser feature called localStorage — a small key-value box that belongs entirely to your browser, on your device, tied to this specific website. It is not uploaded to a server, not attached to your name or email (there's no account system at all), and not visible to anyone else who visits the site. If you never told anyone your score, nobody but you can see it.
What "local" actually means, technically
- It lives in the browser, not the game. When you beat your best distance, a single line of code writes a number to
localStorageunder a key likesd_best. That's the entire mechanism — no network request, no database, no server involved. - It's tied to this browser, on this device. Switch from Chrome to Firefox, or from your school Chromebook to your phone, and you'll see a fresh "0m" — because
localStoragedoesn't sync across browsers or devices. There's no login to tie them together. - Clearing your browser data deletes it. "Clear browsing data," a private/incognito window, or a fresh browser profile all wipe it instantly and permanently — there's no backup copy anywhere else to restore it from.
What this doesn't cover
Being private doesn't mean being invisible to every kind of tracking. Like most websites, this site uses standard analytics (page visits, roughly how long a page stays open) to understand traffic — that's aggregate, anonymized site usage, completely separate from your personal best score, and it's the same category of tracking almost every website on the internet uses. If your school network blocks analytics domains, that data doesn't even reach us; either way, it has nothing to do with your saved distance, which stays local no matter what.
The trade-off, stated plainly
No account system means your progress genuinely can't follow you anywhere — which is exactly why there's no sign-up wall between you and the game, and part of why it's safe to play on a shared or school computer. If you want your best score to survive a browser reset or follow you to a new device, the honest answer is that this design doesn't support that. That's a deliberate trade: less convenience for you, in exchange for nothing about your play history ever needing to exist outside your own browser.
