Cookies & browser storage
Effective September 27, 2026 · Operated by Hanmin Yun, Ontario, Canada
UNIGRID uses browser storage for saves and preferences and a cookie for optional account sign-in. The Squarespace information website has its own cookie controls. This notice explains the distinction.
Inside the game
| Storage | Purpose and duration |
|---|---|
| Account session cookie | The secure, HTTP-only __Host-unigrid_session cookie keeps a player signed in. It lasts up to 30 days and is removed on sign-out. It is restricted to the game host. Blocking it prevents online account functions. |
| Local station library | Browser local storage keeps station snapshots and progress, including the current library and an older save format retained for migration. It stays until removed or cleared by the browser. It is not an advertising identifier. |
| Language preference | Local storage remembers English or Korean until changed or cleared. |
The current game does not install advertising cookies or a separate gameplay-analytics SDK. Infrastructure providers may process technical request data for delivery, security and abuse prevention.
On this Squarespace website
Squarespace uses necessary cookies for website functions and preference handling. Depending on your choices and enabled website features, optional analytics cookies can help measure website visits. Use Cookie Preferences on this website to review the available choices. These website choices do not delete your game saves or sign you out of the separate game host.
Details of Squarespace's cookie categories and durations are available in Squarespace's cookie documentation. Cloudflare describes its infrastructure processing in its privacy policy.
How to control storage
- For optional website cookies, open the website's Cookie Preferences control.
- To end the game's current account session, sign out through My stations.
- To remove local game data, use your browser's site-data settings for unigrid.hanminyun.com. Export important station saves first; removal can permanently erase local progress.
- To request removal of account or cloud-save records, contact snap.memoryun@gmail.com. Clearing cookies is not account deletion.
Browser controls and private-browsing modes can restrict saving. We do not promise identical behaviour across all browsers. See the Privacy policy for purposes, providers and privacy requests.
