This page explains how Hintveil handles information and the rules for the base game and optional AI subscription. Contact the Hintveil developer at the email below.
The base game works offline without registration. Player names, roles, words, game progress, settings and saved decks are stored on your device; offline play does not require uploading this game content to us. System backups depend on your Apple settings. We do not provide ads or track you across apps for advertising.
Creating or revising an AI deck requires an internet connection. Your theme, language, game mode, generation settings and the sanitized public deck title needed for revisions are sent through our Alibaba Cloud service to DeepSeek for generation and necessary content safety checks. Do not enter identifying details, contact information or sensitive information about others. We do not use this content for model training or authorize its use for that purpose. AI does not assign offline player roles.
For AI requests, we verify Apple-signed transactions and query Apple for current subscription status. A hashed subscription identifier and short-term request/concurrency state are held in function memory for abuse prevention. We do not maintain installation identities, DeviceCheck trial eligibility, persistent sessions or monthly usage ledgers. Apple handles payments; we do not receive full card details.
Providers include Apple (purchase verification), Alibaba Cloud (function hosting), DeepSeek (AI processing) and GitHub Pages (website hosting). Network information such as IP addresses is processed for communication and security under providers’ policies. Processing may occur outside your country. We use HTTPS and do not sell personal information.
Local decks remain until you delete them; Apple settings govern system backups. Gateway processes themes and generated words for the request without saving them in a business database or application logs. Temporary abuse-prevention state can reset when functions restart. Providers may retain network/security records under their policies; no fixed deletion period for those records is promised.
You may avoid AI and continue playing the free offline game. Email us to request access, correction or deletion, or to raise a privacy concern. We may need information to verify that a request relates to you. Do not send passwords, private keys, full payment information or secret game words. Requests are handled subject to applicable rights and necessary security, billing and legal retention obligations. Deleting local data does not cancel an Apple subscription.
Minors should use AI and make purchases with a guardian's guidance. We do not ask children for identifying information. Contact us if you believe a child has submitted personal information. We will update this page for material changes and provide additional notice or obtain consent when required.
Hintveil is a face-to-face party game for 3–12 players sharing one iPhone. Base offline play is free and does not require registration. Follow applicable laws and respect other players' privacy.
The complete offline game and built-in decks are free. There is no free AI trial.
Hintveil Pro Monthly is a one-month auto-renewable subscription that unlocks AI deck creation and editing, with no monthly generation allowance. Short-term request and concurrency limits apply. Price, currency and applicable taxes are shown on Apple's purchase confirmation screen. Payment is charged to your Apple account. The subscription renews automatically unless auto-renewal is canceled at least 24 hours before the current period ends. Manage or cancel it in your Apple account's subscription settings. Canceling renewal normally preserves access for the paid period.
AI requires internet and current subscription verification. Outages or temporary rate limits may cause failure or delay; successful generation is not guaranteed for every request. On expiry, refund or revocation, new AI access follows Apple’s current transaction status. Saved decks remain playable offline.
Do not violate privacy or intellectual property rights, request unlawful harmful content, attack the service or bypass eligibility and usage limits. AI output may be inaccurate, unsuitable or repetitive; review it before use. It is not professional advice. You must have the right to submit content. We do not promise exclusive AI output. Abusive requests may be restricted and AI service may be interrupted; normal offline play does not depend on AI availability.
Request refunds through Apple's Report a Problem service; Apple handles them under applicable rules. The app is licensed under Apple's Standard End User License Agreement. This page provides supplementary service and subscription terms and does not replace that agreement or limit mandatory consumer rights. Material changes will be posted here, with additional notice when required.
