Cookie Notice
Effective 19 October 2026.
1. What this notice covers
This page explains, plainly and specifically, what this site and Coin Overload: Reactor store in your browser and what our hosting network may set on its own. It's meant to be read alongside the broader Privacy Notice.
2. Cookies we do not set
Yonderun does not set advertising cookies, does not set analytics cookies, and does not run any tracking script of its own. There is no advertising network on this site, and no analytics tool has been installed.
3. Browser storage this site does use
Nothing below is a cookie in the strict sense — all four entries are your browser's localStorage, which is never transmitted to our server or to anyone else. They're listed here for transparency, alongside anything Cloudflare may set as part of running the site.
| Name | Category | Purpose | Duration | Party |
|---|---|---|---|---|
| cor.best | Functional | Remembers your best score in Coin Overload: Reactor, on this device only | Until you clear your browser's site data | First-party (localStorage, not sent to our server) |
| cor.mute | Functional | Remembers whether you left the game's sound muted | Until you clear your browser's site data | First-party (localStorage, not sent to our server) |
| ydr-cookie | Preference | Remembers whether you accepted or declined this cookie notice, so it isn't shown again | Until you clear your browser's site data | First-party (localStorage, not sent to our server) |
| ydr-age | Functional | Remembers that you confirmed you are 13 or older, so the age check isn't shown on every page | Until you clear your browser's site data | First-party (localStorage, not sent to our server) |
4. Cloudflare
Yonderun is delivered through Cloudflare's network. Cloudflare may, as part of operating that network, apply its own essential security measures to keep the site available and secure. These are part of how the site is delivered rather than something this site's own code sets or controls. See the Privacy Notice for more detail on what that processing involves.
5. Managing storage
You can clear any of the entries above, or block localStorage entirely, through your browser's site-data or privacy settings. Clearing cor.best or cor.mute simply resets your best score or sound preference next time you play; clearing ydr-cookie brings the cookie banner back on your next visit; clearing ydr-age brings the age check back. There's no account to log back into and nothing else on this site that depends on storage beyond these four values.
6. Why the list is this short
Most cookie notices list a dozen or more entries because the site behind them runs advertising auctions, session tracking, or a marketing pixel from one or more third parties. Yonderun runs none of those, which is why this page covers four simple, functional values rather than a long list of categories that don't apply here. If that ever changes, this notice and the table above would be updated to say so honestly before the change went live, not after.
7. Changes to this notice
This notice is updated whenever what the site stores changes. Last updated: 19 October 2026.
