Sleuth the Truth is a free game by Ben Brady. This policy explains what data is collected when you play and how it's handled. The short version: we collect minimal data to keep the game running and don't sell it to anyone.
Prompts & questions. The prompts you use to create boards and the questions you ask during gameplay are sent to our servers and forwarded to third-party AI providers (currently via OpenRouter) to generate responses. These may be logged for debugging, abuse prevention, and improving the game.
Game sessions. Board configurations, secret cards, guess history, and answer results are stored on our servers to power gameplay, puzzles, and the daily leaderboard.
Analytics & metrics. We collect basic usage metrics such as board creation counts, question counts, cache hit rates, and error rates. These are aggregated and not tied to individual identities.
Local storage. Game history, daily streaks, theme preference, and eliminated-card state are stored in your browser's localStorage. This data never leaves your device.
No accounts. Sleuth the Truth does not require registration. We don't collect names, emails, or passwords.
Cloudflare. The game is hosted on Cloudflare Workers. Cloudflare may process standard web request data (IP addresses, headers) per their privacy policy.
OpenRouter / AI providers. Your questions and board prompts are sent to AI models via OpenRouter to generate answers and board content. See OpenRouter's privacy policy.
Wikipedia. Board images and summaries are fetched from the Wikimedia API. No user data is sent to Wikipedia.
Sleuth the Truth does not set any cookies. All client-side state is stored in localStorage.
The game is designed to be family-friendly. We do not knowingly collect personal information from children. Since no accounts or personal data are required, children can play without providing identifying information.
Server-side game session data is retained as long as needed for gameplay and analytics. Question/answer logs may be periodically purged. You can clear all local data by clearing your browser's localStorage for this site.
Since we don't collect personal identifiers, there's typically no personal data to request or delete. If you believe we hold data about you and want it removed, get in touch via the contact details below.
We may update this policy from time to time. Changes will be posted on this page with an updated date. Continued use of the game constitutes acceptance of any changes.
