Sharing with authorized partners

To provide push notification services, we integrate SDKs provided by partners. We may share information necessary to implement the features with the following authorized partners, and we require them to protect your personal information in accordance with applicable laws and this Policy through agreements and other measures:

Push notification service provider: Zhejiang Daily Interactive Co., Ltd. provides the “Message Push SDK (Android)” push technology services. We may provide your device platform, device manufacturer, device brand, device identifiers (including but not limited to IMEI, ANDROID_ID, DEVICE_ID, IMSI, OAID, MAC address, and on HarmonyOS NEXT / HarmonyOS, identifiers such as OAID (HarmonyOS), ODID (HarmonyOS), AAID (HarmonyOS), etc.), installed application list information, network information (including reading the device IP address), and location-related information to Zhejiang Daily Interactive Co., Ltd. to provide push notification technology services. OAID/ODID/AAID, etc. (anonymous or app-level device identifiers, subject to the system and SDK capabilities) are used for device identification and push services; MAC address is used for network connectivity and push link optimization; the device IP address is read by the Message Push SDK (Android) to establish push connections, optimize push links, and improve push delivery success rates; the installed application list is used for push channel keep-alive and link tuning. When we send push messages to you, we may authorize Zhejiang Daily Interactive Co., Ltd. to perform link tuning and mutual wake-up of closed SDK push processes so that you can receive our messages in a timely manner. SDK name: Message Push SDK (Android); developer: Zhejiang Daily Interactive Co., Ltd.; privacy policy: https://docs.getui.com/privacy/.

IV. Third-party SDKs

To implement app features, we use the uni-app framework and the third-party SDKs listed below. For each SDK, we list its name, developer, purpose, permissions used, personal information involved, and privacy policy link for your reference. This information is consistent with the records published on the National SDK Management Service Platform (https://sdk.caict.ac.cn/official/#/home).

Our product is developed based on DCloud uni-app (5+ App/Wap2App). During app operation, we need to collect your device unique identifiers (IMEI/Android ID/DEVICE_ID/IDFA, SIM IMSI, OAID) to provide statistical analysis services, and we analyze launch data and error logs to improve performance and user experience. For details, please refer to the DCloud App Engine Privacy Policy.

Supplement for HarmonyOS NEXT / HarmonyOS: When you use the App on HarmonyOS NEXT / HarmonyOS devices, relevant SDKs or system capabilities may, where permitted by law and consistent with the data minimization principle, collect or use identifiers such as OAID (HarmonyOS), ODID (HarmonyOS), AAID (HarmonyOS), or other device/app-related identifiers (subject to the system version, device manufacturer policies, and SDK implementation) for purposes such as push notifications, analytics, risk control, and security. We will process such information within the scope of your authorization or as permitted by law, and we implement necessary security measures to protect it.
