Privacy Policy

Release date: August 17, 2026
Update date: August 17, 2026

Introduction

Welcome to Curvycare (the "App"). The App is developed and operated by Shenzhen Ainengke Electronics Co., Ltd. ("we", "us", or the "Company") and may be used on Apple, Android, and HarmonyOS. It works with our ultrasonic teeth-cleaning hardware for device connection, live preview, photo/video capture, album management, and help content.

This Privacy Policy explains how we handle information related to the App and the rights you have. Please read it carefully. By using the App, you agree to this Policy. If you do not agree, please stop using and uninstall the App.

1. How We Collect and Use Information

(1) Local connection; images are not uploaded to our servers
The App connects your phone to the device locally: Bluetooth is used to recognize the device and obtain its hotspot name; then the phone joins the device open Wi‑Fi hotspot for live preview and device control on the local network. We do not upload your cleaning images, photos/videos, or album content to our servers.

(2) Information that may be processed locally

  • Bluetooth and device recognition data: to discover and connect compatible devices;
  • Wi‑Fi hotspot name and local network status: to join the hotspot and communicate with the device;
  • Device status (such as battery, light, model identifiers, attitude/angle): for in-app display and feature control;
  • Language and similar preferences: stored on-device for UI display;
  • Basic device information necessary for secure operation: for compatibility and security hardening only—not for marketing profiles.

(3) Photos and videos you capture
Stored on your phone and may also be saved to the system gallery for your own management. You control this content; we do not upload it to the cloud.

(4) Information we do not collect unnecessarily
No account is required. We do not collect sensitive personal information unrelated to local cleaning features, such as your name, ID number, or phone number. We do not use location for maps, tracking, or profiling. Where an OS requires related capabilities to discover nearby devices, we use them only to find our hardware.

2. Permissions

To provide these features, the App may request the permissions or system capabilities below. Names may differ by platform. You may revoke them in system settings; some features may then become unavailable:

  • Bluetooth: to recognize the device and obtain connection information;
  • Wi‑Fi / Local Network / Nearby devices: to join the device hotspot and preview/control the device on the LAN;
  • Photos / Media / Storage: to save, view, and manage your photos and videos;
  • Network access: for local communication with the device, and for opening links you choose (such as an ICP filing page).
Note: The device hotspot is typically for direct hardware communication and usually cannot access the public Internet. A “No Internet” prompt is expected and does not mean we collect your browsing activity.

3. Storage and Security

  1. Photos, videos, settings, and connection-related data are stored mainly on your device.
  2. We take reasonable measures to protect the App, including third-party hardening where appropriate.
  3. Please keep your phone and gallery safe. To the extent permitted by law, we are not responsible for risks arising from your sharing or backups to third parties, device loss, or system failure.

4. Third-party SDKs

For app hardening, the App may integrate the following SDK, which may collect necessary basic device information:

Partner: Beijing Qihoo Technology Co., Ltd. (360 App Guard)
Purpose: App hardening against cracking, reverse engineering, and repackaging
Data type: Basic device information
Official link: https://jiagu.360.cn/#/global/details/app

Except as described above or required by law, we do not sell your personal information.

5. Minors

If you are a minor, please use the App under a guardian’s guidance. We do not knowingly collect minors’ sensitive personal information.

6. Your Rights

  1. Revoke related permissions in system settings;
  2. Delete photos and videos in the App album;
  3. Uninstall the App to stop using our services. Private app data is typically removed after uninstall; files already in the system gallery may remain until you delete them.

7. Updates

We may update this Policy and notify you in the App. Continued use means you accept the updated Policy.
