Yueche Nanxia Community (the “App”, “we”, “us”, or “our”) values your personal information and privacy. We process and protect your personal information in accordance with the principles of lawfulness, fairness, necessity, and good faith.

Please read and fully understand this Privacy Policy before using the App. After you tap to agree, or otherwise clearly indicate your consent, we will process your personal information in accordance with this Policy.

If you do not agree with this Policy, you may stop using the relevant services.

1. Who We Are

• App name: Yueche Nanxia Community
• Operator: Dongguan Yongzhi Technology Co., Ltd.
• Contact email: i@znnu.com

The App mainly provides information related to Yueche Nanxia, article reading, vehicle plate and lottery query tools, map and location marker browsing, current location and nearby place display, distance calculation, in-app messages, account login, favorites, browsing history, and push notifications.

2. How We Collect and Use Your Personal Information

We only collect information that is necessary for the specific features you use.

If you refuse to provide certain information, you may be unable to use the corresponding feature, but other features that do not rely on that information will not be affected.

Account Registration, Login, and Identity Verification

When you use a phone number, email address, or WeChat to log in, register, or bind an account, we may process the following information:

• Phone number or email address;
• Verification code validation result;
• Account ID;
• Login credential and login status;
• Login time, login IP address, and necessary security logs.

When you use WeChat login or binding, after obtaining your authorization, we may receive the authorization code, OpenID, UnionID, nickname, avatar, and other public profile information returned by WeChat, for identity verification, account login, and account binding.

We do not store your password in plaintext, and we do not sell or illegally provide your phone number, email address, or WeChat account identifiers to unrelated third parties.

User Profile Features

When you actively edit your profile, we may process the nickname, avatar, and other profile information you submit, for displaying and managing your user profile.

To maintain a healthy community environment, we may conduct format validation, sensitive word checks, or necessary content safety review on the nickname, avatar, and other content you submit.

Article Reading, Favorites, and Browsing History

When you use article-related features, we may process the following information:

• Article identifier;
• Reading time;
• Favorite status;
• Browsing record;
• Account ID.

This information is used to display content and synchronize favorites and browsing history.

If you are not logged in, we will not generate account-level favorites or browsing history for you, but necessary page state and cache may be stored on your device.

Vehicle Plate Query and Lottery Query

When you use vehicle plate query, lottery query, or similar tools, we may process the following information:

• Query conditions you actively enter;
• Query time;
• Query results;
• Necessary API request logs and troubleshooting logs.

This information is used to complete your query request and perform necessary troubleshooting.

Please do not enter sensitive personal information unrelated to the query purpose, such as ID card numbers, financial accounts, or medical and health information.

In-App Messages and Notifications

When you use in-app message features, we may process the following information:

• Account ID;
• Message content;
• Message type;
• Sending and receiving time;
• Message read status.

This information is used to send, display, and manage in-app messages.

Push Notifications

After you allow system notification permission, we may process the device push token, app identifier, and push status generated by Apple Push Notification Service (APNs), so that we can send article notifications, in-app message notifications, and service notifications to your device.

We do not use push tokens for advertising tracking.

You can disable notification permission for the App at any time in iOS Settings.

Security, Risk Control, and Service Stability

To protect account, API, and service security, we may process the following information:

• IP address;
• Network type;
• Device model;
• Operating system version;
• App version;
• Request time;
• Account ID;
• Error information and crash information;
• Necessary operation logs.

This information is used only for identity verification, security risk control, statistical analysis, operation and maintenance, and troubleshooting. It will not be used for purposes unrelated to the App services.

When you use SMS verification code login, registration, phone number binding, or trigger security verification, we may process necessary information related to bot detection and security risk control through the GeeTest CAPTCHA v4 SDK and backend secondary verification service, such as device brand, device model, operating system and version, system language, device name, memory size, carrier information, screen size, whether the device is a tablet, IP address, network status, whether Wi-Fi is used, network type, verification interaction result, verification serial number, verification result, and necessary logs.

This information is used only to identify security risks such as automated scripts, malicious requests, bulk registration, and abuse of SMS verification codes. It is not used for personalized advertising or cross-app tracking. We initialize or call the relevant security verification SDK only after you agree to this Privacy Policy; the verification capability is called only when you actively trigger a feature that requires security verification.

Maps and Location Services

When you actively enter the map page, view your current location, view nearby markers, or calculate distance to a place, after obtaining your location authorization, we will use iOS system location service CoreLocation to obtain your precise or approximate location, including latitude and longitude.

Location information is used to:

• Display your current location on the map;
• Display or filter nearby places and markers;
• Calculate the distance between you and marker locations;
• Improve map browsing and place viewing experience.

Location information is sensitive personal information. We process it only within the scope necessary to provide the above features.

The App does not continuously obtain your location in the background, and does not use location information for user profiling, personalized advertising, or cross-app tracking.

Unless otherwise required by laws and regulations, or unless you actively submit it, we do not store your real-time location for a long time on our business servers.

Location permission is not required for using the App as a whole. You may refuse authorization or withdraw authorization in system settings. After withdrawal, only current location, nearby places, distance calculation, and related features will be affected.

3. System Permissions and Device Capabilities We Use

Notification permission: used to receive article notifications, in-app messages, and service notifications. This permission is optional and is usually requested when push notifications are first enabled. If you refuse it, you will not receive system push notifications, but other in-app features will not be affected.

Location permission while using the App: used to display your current location, nearby places, and calculate distance. This permission is optional and is usually requested when you actively use location-related features. If you refuse it, current location, nearby places, and distance calculation will not be available.

Precise location: used to improve map positioning and distance calculation accuracy. This permission is optional and is provided by the system after location permission is enabled. If you disable precise location, only approximate location may be available.

Photo library or file permission: used to select or upload avatars and files. This permission is optional and is requested only when you actively choose relevant content. If you refuse it, you cannot select or upload the corresponding content.

Network access: used to access backend APIs and load articles, maps, and query data. Network access is required for online features; without network access, network content and online features cannot be used.

You can view, enable, or disable relevant permissions in iOS “Settings - Privacy & Security” or the App’s system settings page.

Withdrawing authorization will not affect lawful processing already conducted based on your authorization before withdrawal.
