About this notice
Last updated: September 5, 2026. This notice describes the data handling used by Cage Grind’s current browser game.
Data saved on your device
Cage Grind uses browser storage for your saved career, preferences, and network session. The game also caches app files for faster loading and offline availability. Session information connects your browser to your network fighter identity.
You can remove local storage and cached files using your browser’s site-data settings. Doing so can remove your local progress or access to your saved career. It does not automatically erase records already stored by the online game.
Online fighter and social data
The game uses Supabase for authentication and online features. Data sent to the service includes fighter identity and career information, fight results, rankings, social activity, and referral information needed to run those features.
Your fighter name, chosen hometown, avatar, record, level, ranking, cosmetic Fight Skin, and public feed activity may be visible to other players. Your chosen fighter hometown is profile information, not a request for your device’s precise location. Avoid using sensitive personal information in public names or posts.
Invites
Invite links include a fighter identifier so the game can associate a new fighter with the inviter and validate the first-fight reward. Anyone you share the link with can see that link and its identifier.
Analytics and service providers
The game loads Google Analytics to measure visits and gameplay events. Google Analytics may use cookies or similar identifiers and process device, browser, and usage information. Your browser communicates with Google and Supabase when their features are used; these services can also receive technical request information such as your IP address.
See Google’s Privacy Policy and Supabase’s Privacy Policy for their practices. Browser privacy settings and content blockers may limit analytics; blocking game storage or online services can affect gameplay.
Retiring and clearing data
Retiring a fighter is a gameplay action, not a promise that all related online records are deleted. Public fight history or social activity may remain. Clearing your browser data only clears data on that browser.
Changes
This notice may be updated as game features or data handling change. The date above identifies the latest revision.
