Privacy and measurement
How Fantasy Solvers – Balatro Lab handles game states, browser storage and analytics.
Game state
Solver requests are transmitted to the Fantasy Solvers native service for computation. Requests are bounded and worker processes terminate after completion or cancellation. The application does not persist card states, Joker notes or complete shared URLs on the server.
Browser library and links
Saved custom item definitions remain in your browser localStorage. Share links can contain card state and referenced custom definitions in their URL fragment. Anyone receiving the complete link can read them. Clearing browser storage removes your local library.
Analytics
At the site owner's request, public pages load Google Analytics 4, measurement ID G-5LL2XLMS9M. Google Analytics may use first-party cookies to distinguish visits and returning browsers. Page URLs are reduced to origin and path; query strings, fragments, game states and custom descriptions are not intentionally sent as analytics parameters. We track completed solver requests, unsupported-state events, shared-state loads, state-link copies and MCP-endpoint copies using allowlisted categories, not card contents. Advertising personalization and Google signals are disabled in the website tag. The tag is not loaded when the browser exposes Global Privacy Control or Do Not Track, or on localhost.
Google privacy policy · Google Analytics opt-out. Browser privacy settings and blocking extensions can affect measurement.
Operational metrics
Aggregate route, response-status and tool-completion events may be logged for reliability and discovery measurement. Crawler classification is kept separate from evidence of assistant citation or tool use. No user ID, game state, query string or custom notes are included in these operational events.
Scope and trust
Supported model: 20 validated Jokers, 150 catalog names; exact analysis accepts 1–8 hand cards, 0–12 draw cards, 1–2 hands and 0–2 discards. Uniform replacement draws and optimal continuation are assumed. Unsupported boss, consumable, shop, history and scaling effects are rejected. No standalone sampled full-deck advice. Card order is optimized; Joker slot order is preserved.
Mathematical action values are conditional on the stated game model, not estimates of real-game success. Equal values are ties. Incomplete searches provide no completed recommendation. This independent tool is not affiliated with the game publisher.
