1. Scope and Relationship to Terms

This Privacy Policy describes how 4tune3 Co., Ltd. ("Company", "we", "us", "our") collects, uses, shares, and protects information when you use the Blackjack AI application (the "Software") and the game and related services provided through it (the "Service").

This Privacy Policy forms part of the Blackjack AI Terms of Service ("Terms"). By using the Software and the Service, you consent to the practices described in this Privacy Policy. If you do not agree, please do not use the Software or the Service.

2. Platforms We Support

The Software and Service may be offered on or accessed through third-party platforms, storefronts, social networks, operating systems, or websites (collectively, "Platforms"), including but not limited to Apple App Store (iOS), Google Play (Android), Facebook, and web-based platforms. Some Platform features (for example, sign-in, billing, or analytics) may be governed by the Platform’s own policies.

3. Information We Collect

We collect information to operate the Service, improve gameplay experience, provide support, prevent fraud, and comply with legal obligations.

The categories below may vary depending on your device, Platform, settings, and how you use the Service:

A. Non-Personal / Device & Usage Information (may include):

·       Device and software information (OS version, app version, hardware model, carrier/network information)

·       Gameplay and usage data (session duration, feature usage, interactions, high scores, crash/incident logs, and diagnostics)

B. Personal Information (may include):

·       Transaction identifiers, purchase receipts, and subscription status (we do not receive your full credit card number when Platform billing is used)

·       Information you provide to us (for example, messages sent to Customer Support, or content you post where such features exist)

C. User-Generated Content and Community Features:

If the Service offers chat, message boards, comments, or similar features, any content you choose to post may be visible to others depending on the feature design and your settings. Please do not post information you want to keep private.

4. Third-Party SDKs, Advertising, and Analytics

We may use third-party advertising, attribution, and analytics tools/SDKs to help us understand usage, measure marketing effectiveness, and serve ads where applicable. These providers may collect information through the Software and Service using technologies such as SDKs, cookies (for web), and similar identifiers.

Information collected by these providers may include device identifiers, IP address, approximate location, in-game events, and interaction data. Their collection and use are subject to their own privacy policies.

5. How We Use Information

We may use information we collect to:

·       Provide and operate the Service (including account features, gameplay functionality, and security)

·       Improve, debug, and optimize performance and user experience

·       Provide customer support and respond to requests

·       Process purchases, validate receipts, and manage subscriptions (typically via Platform/Payment Provider systems)

·       Detect, prevent, and investigate fraud, abuse, or security incidents

·       Comply with applicable laws and enforce our Terms

·       Send service-related notices and, where permitted, notifications about features, updates, or products (you may control notifications via device/Platform settings)

6. Information Sharing

We do not sell your personal information. We may share information in the following cases:

·       Service Providers: with vendors who help us operate the Service (hosting, analytics, customer support, fraud prevention), under appropriate contractual protections

·       Platforms: with the Platform you use for sign-in, distribution, billing, refunds, or compliance, as required to provide the Service

·       Legal and Safety: if we believe in good faith that disclosure is required by applicable law, regulation, legal process, court order, or governmental request, or is necessary to investigate security breaches or fraud, or to protect rights, safety, and property

·       Business Transfers: in connection with a merger, acquisition, reorganization, or sale of substantially all assets (subject to this Privacy Policy as it existed at the time the data was collected, unless you are notified and consent where required)

If you click a link to a third-party site or advertiser within the Software, that third party may collect information from you directly. We do not control third-party sites and are not responsible for their practices.

7. Cookies (Web Versions)

If you access the Service through a web-based Platform, we and our partners may use cookies or similar technologies to remember preferences and collect aggregated usage statistics. You can configure your browser to accept or deny cookies.

8. Age Requirement

Unless stated otherwise, the Service is intended for users who are 18 or older for entertainment purposes only. We do not knowingly collect personal information from children under 18. If we learn that a person under 18 has provided personal information, we will take reasonable steps to delete it as soon as possible.

9. Data Security

We store and process information on our servers and use reasonable technical and organizational measures designed to protect information from accidental loss and unauthorized access, use, alteration, or disclosure. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security. Please be cautious when communicating with others through the Service.

Please note: we may retain certain information where required by law, for legitimate business purposes (e.g., fraud prevention, dispute resolution), or in backups for a limited period.
