Updated 17 September 2026. Rival Ledger is a free browser game prototype.
Your game stays on your device
The game stores up to 40 completed runs in this browser: outcome, duration, fictional assets collected, upgrades, difficulty, seed and date. These records are not uploaded. “Your run history” lets you export or clear them. Clearing site data also removes them. Offline files may be cached by your browser so you can play again without a connection.
Optional challenge sharing
After a run, “Challenge a friend” lets you share your result through your device’s share menu or copy it. A challenge link contains only the game rules version, starting seed and difficulty, in the part after #. It contains no player identity, contact information or stored run history. Result text may include your outcome, time and department. You choose the destination; we do not send messages or collect your contacts. Sharing is never automatic. Your choices during play change how a shared seed unfolds.
Optional game feedback
After a finished run, you may choose to send two ratings: whether you want another dungeon and how the difficulty felt. Only pressing “Send feedback” uploads those answers, your difficulty mode, win/loss outcome, department reached and game feedback version. We also store the submission day and a random submission code to prevent a retry being counted twice. The code belongs to this submission, not an account or device profile. We do not ask for a name, email or free-text message. The feedback database does not store your IP address, browser details, full run history or a device identifier.
This feedback helps decide what to improve. It is optional and does not affect your game. Offline and downloaded/native copies do not queue uploads. Records older than 90 calendar days are removed when the next feedback submission is processed; this is not a scheduled deletion service. Feedback rows are private to the site operator. Feedback is not a verified count of people or purchases.
No account, ads or purchases
This version has no registration, analytics SDK, ad provider or payment integration. Game coins and assets are fictional and cannot be redeemed for money. The hosting providers, OpenAI Sites and Cloudflare, may process technical request logs to serve and protect the site; their own retention policies apply to those logs.
Former consultancy requests
The former consultancy has closed. New research requests are no longer accepted, and previous request information is not used for game marketing. If you previously submitted a request, the deletion code you received still removes it from the application database. Keep that code private.
