Dear User:
The Pinyin Typing Master application is a Pinyin typing service product (hereinafter referred to as "Daimajiang Tech") provided to you by Fuzhou High-tech Zone Daimajiang Technology Co., Ltd. (Registered address: Room 510-3, Building 2, China Metallurgical Geology, No. 1 Keji East Road, Jianping Village, Shangjie Town, Minhou County, Fujian Province, China; Contact: daimajiang@163.com). Daimajiang Tech deeply respects your personal information and data, and will do its utmost to keep your personal information and data safe and reliable. This policy applies only to the user information and data collected and stored by the Pinyin Typing Master application. Before using the Pinyin Typing Master application, please carefully read, understand, and agree to this Privacy Policy. This policy sets out how we will collect, use, disclose, process, and protect the information you provide to us when you use the Pinyin Typing Master application. When we need certain information from you to verify your identity while using the product, or when connecting services with our third-party service providers, we will strictly follow this privacy policy in using such information. If you have begun to use the Pinyin Typing Master application, this indicates that you have read, consented to, and accepted all terms described in this privacy policy, as well as any changes we may make at any time in the future. In addition, you must commit that you are already an adult when you begin to use this product; if you are a minor, you need your guardian's consent to use this product and to agree to the related service terms and privacy policy.
1. Information Required for Account Registration and Login
This application uses the following account systems: self-registration and third-party (QQ Login, WeChat Login) authentication. The application server only stores the openID obtained from third-party (QQ or WeChat) interfaces. The user's nickname and avatar come from third-party APIs. Currently, only self-registration is supported; third-party authentication login will be introduced in the future.
In theory, a user's third-party openID cannot be used to derive the user's QQ or WeChat account or password. Therefore, this application has no possibility of leaking such information. As for the user's nickname and avatar, although they are not important personal information, and the self-registered password, we will still encrypt the data and keep it properly to prevent leakage.
If you wish to deactivate a specific product or service, you can go to [Me] -> [Settings] to perform account deactivation. We will delete your personal information. After you perform the deactivation operation, there will be a seven-day cooling-off period, during which you can restore your account use. After the cooling-off period ends, your account and related data will be deleted immediately. After deletion, you will no longer be able to use certain features or services. Please proceed with caution.
2. Collection of Device-Related Information and Permissions
1) To learn the device information on which our App runs and facilitate optimization, we need to silently obtain the following from your device: device model, device serial number, operating system version, and screen resolution.
