Welcome to "ChessHop"! We understand the importance of personal privacy. This Privacy Policy outlines how we collect, use, store, and protect your relevant information, as well as our special declarations regarding the use of specific cloud AI services within the App.
1. Guest Data: When you use the "Guest Mode" directly without registering, we generate an anonymous device identifier to record your level clearance data, existing Credits, and ELO rating locally on your device (Local Storage). In this mode, unless data corruption occurs, relevant game progress is only kept on this device.
2. Account and Login Information: The App supports "Sign in with Apple". When you choose "Sign in with Apple", depending on your system-level permissions, we may receive a desensitized account credential to establish a unique ID (excluding your real name and real email, unless you actively authorize Apple to transmit it). This is used for your cross-device save data and cloud backup synchronization of Credit information.
3. In-Game Behavior and Data: We will record your game win/loss count, star rating for each level, remaining Credit amount, game duration, and operation frequency. These data will only be used to: (a) maintain basic App functions; (b) optimize the game difficulty experience under AI matchmaking.
1. The App features an "In-Game AI Mentor Dialogue" function. When you trigger specific moves (such as Check, Capture, Castling, etc.) or initiate a dialogue, we will obtain the current historical state of the chessboard (SAN notation) and send it as a non-real-name structured request to the data interface provided by a trusted third-party Large Language Model (LLM) service provider for processing, in order to generate "character dialogue" lines.
2. Important Security Warning: This is not processed locally, but is a request sent to a cloud service. Although we will desensitize the chessboard instruction text transmitted (only transmitting move notations and virtual display nicknames), we still remind you: Please absolutely DO NOT attempt to input and submit any state secrets, trade secrets, your bank accounts, location, or personal privacy characteristics in any possible custom input boxes or games. Any irrelevant privacy leakage caused by the player themselves is the player's own responsibility.
1. We use security protection mechanisms that comply with industry standards (such as encrypted communication) to protect your synchronized data.
2. Except for the aforementioned LLM third-party providers, we will not sell, trade, or unjustifiably disclose your privacy information that can locate your real name and physical device to any other third party, unless facing mandatory intervention by law and law enforcement agencies.
3. All data logs are strictly kept in accordance with the storage years permitted by law, and will be cleared and irreversibly unrecoverable when the year limit is reached or when you request deletion.
1. In accordance with the privacy protection requirements of the latest App Store Review Guidelines, you have the complete autonomous right to choose to permanently delete your account and account-related cloud game data within the App at any time.
2. You may perform the above operation by going to the App — [Profile] — [Settings] — and finding the [Delete Account and Data] entry. Once the cancellation is completed, all historical records and "Credits" purchased with fiat currency but not yet consumed in the app will be completely destroyed along with it, and cannot be recovered.
3. If you need to consult, revoke Apple SignIn authorization, or request to exercise your right to access information, you can also contact us for resolution via the email address attached at the end of this document. We will process it within 15 working days upon receipt.
In accordance with the "APP Compliance Guidelines", we do not subjectively and intentionally collect personal information from minors under the age of 14. If a user lacks full civil capacity and an in-app purchase occurs without the protection of a legal guardian, please promptly contact us through the customer service channel for proper handling.
If you have any questions, opinions, or suggestions about the privacy policy and information protection, please contact the developer:
