1. Website analytics

This website uses Baidu Analytics to collect basic visit data, so we can understand page traffic and download conversion. The analytics script is loaded from Baidu's servers and may record general information such as pages visited, referral source, and device type. The specific data processing by Baidu Analytics is governed by Baidu Analytics' own privacy statement.

2. Kuaiyatu

Kuaiyatu's image compression runs locally on your phone. Based on the permissions declared by the current APK, Kuaiyatu requests the following system permissions:

  • Read media images (READ_MEDIA_IMAGES): to select the phone photos you want to compress.
  • Read/write external storage (READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE, on older system versions only): to access images and save results on older systems.
  • Foreground service and notifications (FOREGROUND_SERVICE, POST_NOTIFICATIONS): to keep compression tasks running and show prompts in the background.
  • Network and network state (INTERNET, ACCESS_NETWORK_STATE): used for analytics SDK reporting.
  • Wake lock and boot completed (WAKE_LOCK, RECEIVE_BOOT_COMPLETED): used for task-scheduling features.
  • Advertising ID (AD_ID): used by the analytics SDK.

Kuaiyatu includes the Umeng analytics SDK for anonymous usage statistics and product-experience improvement; its data processing is governed by Umeng's privacy policy. Image processing happens primarily on the device, and original images are not actively uploaded.

3. Kuailuping

Kuailuping's screen recordings are processed on your phone and saved to your local gallery. Based on the permissions declared by the current APK, Kuailuping requests the following system permissions:

  • Record audio (RECORD_AUDIO): to record microphone sound.
  • Media-projection foreground service (FOREGROUND_SERVICE, FOREGROUND_SERVICE_MEDIA_PROJECTION): to perform screen recording.
  • Notifications (POST_NOTIFICATIONS): to show the recording-status notification.
  • Network and network state (INTERNET, ACCESS_NETWORK_STATE): used for analytics and crash reporting.
  • Advertising ID (AD_ID): used by the analytics SDK.

Kuailuping includes the Umeng analytics SDK and components related to Tencent Bugly crash reporting, used respectively for anonymous usage statistics and crash diagnosis; their data processing is governed by those third parties' privacy policies. Recordings are kept on the device and are not actively uploaded.

4. Notes and limitations

The permission and SDK information above is based on static inspection of the current APK. The exact circumstances in which each permission is triggered at runtime depend on the app's actual behavior. If permissions or third-party components change, this policy will be updated accordingly.
