(I) Information collected and used when you use our products or services

We collect and use your user information only for the business functions described in this policy. The purpose of collecting such information is to provide you with our products or services. You may choose at your discretion whether to provide this information; however, in most cases, if you decline to provide it, we may be unable to deliver the corresponding service or address issues you encounter.

When you use our services, we may collect information that you voluntarily provide to us or that is necessary to deliver our services, including: account nickname, password, password protection options, email address, phone number, and device information.

II. How we use cookies and similar technologies

(I) Cookies

To ensure the proper functioning of our website, we store small data files called “cookies” on your computer or mobile device. Cookies typically contain identifiers, site names, and some numbers and characters. Using cookies, websites can store your browsing preferences.

We will not use cookies for any purpose beyond those described in this policy. You may manage or delete cookies according to your preferences. You may delete all cookies saved on your computer, and most web browsers offer settings to block cookies. However, doing so requires you to manually adjust your user settings each time you visit our website.

(II) Web beacons and pixel tags

In addition to cookies, we also use other similar technologies on our website, such as web beacons and pixel tags. For example, emails we send you may contain links pointing to content on our website.

If you click such a link, we track that click to better understand your product or service preferences and improve customer service. Web beacons are typically transparent images embedded in websites or emails. Pixel tags in emails allow us to determine whether an email has been opened. If you prefer not to have your activities tracked in this manner, you may unsubscribe from our mailing list at any time.

(III) Do Not Track (DNT)

Many web browsers include a Do Not Track feature, which sends a DNT signal to websites. Currently, major internet standards organizations have not established policies specifying how websites should respond to such signals. However, if your browser has Do Not Track enabled, all our websites will honor your preference.

III. How we share, transfer, or publicly disclose your user information

(I) Sharing

We do not share your user information with any other company, organization, or individual, except in the following circumstances:

1. Sharing with explicit consent: We will share your user information with third parties only after obtaining your explicit consent.

2. Sharing as required by law: We may share your user information in accordance with legal requirements or mandatory requests from governmental authorities.

3. Sharing with affiliated companies: Your user information may be shared with our affiliated companies. We will share only the minimum necessary user information, strictly limited to the purposes stated in this Privacy Policy. If an affiliated company intends to change the purpose for which user information is processed, it will seek your renewed authorization and consent.

4. Sharing with authorized partners: Certain of our services are provided by authorized partners. To enhance customer service and user experience, we may share certain of your user information with these partners. We share your user information only for lawful, legitimate, necessary, specific, and explicit purposes, and only the minimum information necessary to deliver the service. To better operate and improve our technology and services, you agree that we and our authorized partners may, subject to applicable laws and regulations, use collected information for other services and purposes.

Below is a list of specific authorized partners, along with links to their respective privacy policies. We recommend that you review their privacy policies:

(1) Push Notification Service Provider: GeTui Inc. provides push notification technical services. We may share with GeTui Inc. certain device information—including device platform, device manufacturer and brand, device model and system version, device identifier, device serial number—as well as app list information, network information, and location-related information, to enable push notification services. When delivering push notifications to you, we may authorize GeTui Inc. to optimize connection pathways and mutually reactivate SDK push processes that have been disabled, thereby ensuring timely delivery of our push notifications to you. For details, please refer to GeTui’s User Privacy Policy.

① Device information: Device identifiers (see “Privacy Policy”), device platform, and device manufacturer are used to generate a unique push target ID (CID) and device ID (GID), ensuring accurate message delivery and precise device identification. Device brand, device model, and system version are used to optimize channel resource efficiency, enhancing message delivery rates and stability. Additionally, to ensure CID uniqueness and improve push stability and accuracy, you must grant storage permissions (WRITE_EXTERNAL_STORAGE, READ_EXTERNAL_STORAGE) and device permissions (READ_PHONE_STATE).
② App list information: We employ merged-channel technology for push delivery. When multiple apps on a single device simultaneously maintain active push channels, we randomly merge them into one channel to conserve battery power and data usage for users. Thus, access to app list information is required. We also provide intelligent push functionality, using this information to recommend more relevant push content tailored to your needs, reducing unnecessary push notifications. You may choose to enable or disable this feature; however, disabling it may increase battery consumption and data usage.
③ Network information [including IP address, Wi-Fi information (SSID, BSSID), cell tower information, carrier information] and location-related information: To maximize network connection stability and establish persistent long-lived connections, we need to monitor device network status and changes, enabling stable and continuous push services. Our context-aware push feature uses location-related information to deliver refined, location-specific push notifications, recommending more relevant content and reducing irrelevant push messages.
④ To ensure timely message delivery while you use push notification services, you may authorize us to optimize connection pathways and mutually reactivate SDK push processes that have been disabled, thereby ensuring effective message delivery.
To ensure stable operation and full functionality of our push services—and to enable you to access and enjoy additional features and services—our services integrate software development kits (SDKs) and application programming interfaces (APIs)[1] provided by our partners. We conduct rigorous security assessments of partner-provided SDKs and APIs[2], and require partners to implement strict data protection measures, mandating that they process personal information in accordance with this Privacy Policy and any other applicable confidentiality and security measures. Below are details of our integrated partners; we recommend reviewing their respective privacy policies:
SDK Name: ZhuoXin ID
Information Collected: Weak device identifiers (features lacking uniqueness and stability): device information (device manufacturer, device model, device system information), device network information (network connection method and status), device environment information (screen brightness, battery status, country, device app information [versions and installation status of common apps]),
Purpose: To provide device identification and security risk control services,

2. Transfer in connection with mergers, acquisitions, or bankruptcy proceedings: In cases involving user information transfers due to mergers, acquisitions, or bankruptcy liquidation, we will require the new entity holding your user information to remain bound by this Privacy Policy. Otherwise, we will require the new entity to obtain your renewed authorization and consent.

(III) Public Disclosure

We will publicly disclose your user information only in the following circumstances:

1. After obtaining your explicit consent;

2. Legal disclosure: We may disclose your user information when required by law, legal process, litigation, or mandatory requests from governmental authorities.

(IV) Exceptions to obtaining prior authorization and consent for sharing, transfer, or public disclosure

Please note that, pursuant to applicable laws, regulations, and relevant national standards, we are not required to obtain your authorization and consent for sharing, transferring, or publicly disclosing your user information in the following circumstances:

1. Directly related to national security or national defense security;

2. Directly related to public security, public health, or major public interests;

3. Directly related to criminal investigation, prosecution, trial, or enforcement of judgments;
