Privacy Policy
Effective: 2026-09-14 (previous version: 2026-08-31)
1. Data We Collect
Yes No Detective (the "Service") can be used without creating an account. We collect: · Anonymous identifier · a random ID stored in your browser (localStorage), not linked to your name or contact details. · Gameplay records · the question/answer text you type, AI verdicts, and scores; used to improve verdict quality and analyze misjudgments. · IP address · used only for daily usage limits and abuse prevention. · Error & performance data · for diagnosing service errors (Sentry). · Usage analytics · page visits and gameplay events (PostHog). No advertising trackers. · (Optional) Google Sign-In · only if you choose to back up your progress; we store your Google account identifier and email address. Your profile name and photo are kept in your browser for display only and are not sent to our server. · (Optional) Marketing consent. When signing in with Google you may opt in to receiving game news and updates by email; we store whether and when you consented. Consent is never a condition of using the Service, can be withdrawn anytime on the My Account page, and is removed when you delete your server backup. · Age verification result · before the game starts you confirm (by checkbox) that you are 18 or older. We do not ask for your date of birth or age; only the fact that you confirmed, with its timestamp, is kept in your browser (localStorage) and is not sent to our server.
2. About AI Processing
The dealer of this game (the "Archivist") is an AI. Question and answer text you enter is sent to an external AI provider (Google Gemini API) for judging. In addition, question text may be sent to OpenAI to generate embeddings for verdict caching, and question/answer text may be sent to OpenAI for fallback judging when Gemini is unavailable. Case stories (produced with the help of AI tools) and artwork (AI-generated) are fiction, unrelated to real people or events. AI verdicts may occasionally be inaccurate.
3. Cookies & Local Storage
We use no advertising or tracking cookies. Your browser's localStorage holds the anonymous identifier, settings, and progress records; clearing browser data removes them (a linked Google backup remains on the server).
4. Retention
· Active game-room state: automatically deleted within 24 hours after the last activity. · Gameplay logs: retained for up to 3 years from collection, then deleted. Deletion requests are honored without undue delay regardless of this period. · Account backups: retained until account deletion or a deletion request.
5. Processors
We rely on: Vercel (hosting), Supabase (database), Google (Gemini API for AI judging; Google Sign-In if you opt in), OpenAI (fallback AI judging and question embeddings; content-production tools), Sentry (error reporting), and PostHog (analytics). We do not sell personal data or provide it to third parties.
6. International Data Transfers
The processors above are overseas businesses or use overseas servers, so personal data is transferred to and stored abroad in the course of providing the Service. · Transferees: Vercel, Supabase, Google, OpenAI, Sentry, PostHog (each company's contact details are published on its website) · Country: United States (details including the Supabase hosting region to be confirmed and updated) · Data: among the items in Section 1, the scope needed for each processor's task · When and how: continuous network transmission as you use the Service · Purpose and retention: within each processing task's purpose, until the processing contract ends or the periods in Section 4 If you do not wish your data transferred, you may stop using the Service and request deletion via the contact below.
