Key Notice: This application is a utility tool designed to connect and control the smart stringing machine. No registration or account login is required. We do not collect any personal identity information (such as your name, phone number, email, or third-party accounts). All custom stringing parameters are stored strictly locally on your device.
1. Introduction
Pusun Stringing Machine (hereinafter referred to as "the App" or "we") is developed and operated by Shenzhen Pusun Intelligent Sports Co., Ltd. We are strictly committed to protecting your privacy and complying with applicable privacy laws and Apple's App Store Review Guidelines.
Please read this Privacy Policy carefully before using the App. By downloading, installing, or using the App, you acknowledge and agree to the terms described herein.
2. Information Collection and Usage
As a lightweight hardware control utility, the App strictly adheres to the "data minimization" principle. We only request permissions and handle data that are strictly necessary for connecting and controlling the stringing machine:
| Permission / Data |
Purpose & Usage Scenarios |
Acquisition |
Requirement |
| Bluetooth Permission |
Used to scan nearby smart stringing machines via Bluetooth Low Energy (BLE), establish a wireless connection, transmit control commands (such as tension, pulling speed, knot, and pre-stretch settings), and receive real-time device telemetry.
|
System authorization prompt upon first use |
Essential
Cannot connect to the machine if denied |
Local Storage
(Sandbox) |
Stores user-defined stringing presets (such as tension profiles for tennis/badminton rackets) and local pulling counter records within the iOS application private sandbox.
|
Saved locally by user actions |
Optional
Does not affect basic controls |
Camera Permission
*Optional* |
Activated only if you choose to scan the QR code on the machine to pair. Used exclusively to recognize the device pairing code. We do not capture photos, record videos, or transmit visual data.
|
Explicit user consent when scanning |
Optional
Can connect via Bluetooth list directly |
Explicit Declarations:
- No Account System: The App does not require registration, SMS codes, or third-party logins (such as WeChat or Sign in with Apple). No cloud-based user profile database is created.
- No Personal Identifiable Information: We do not collect your name, phone number, contacts, messages, GPS location, or photo gallery.
- No Tracking & No Ads: The App does not access the IDFA (Identifier for Advertisers), contains no advertising/tracking SDKs, and does not track user activity across other companies' apps or websites under the App Tracking Transparency (ATT) framework.
3. Third-Party SDKs and Data Sharing
To ensure a secure and minimal operational environment:
- No Third-Party Social/Ad SDKs: The App does not integrate any third-party social login, push notification, or advertising SDKs.
- No Data Sharing or Sale: We will never sell, lease, share, or transfer any of your hardware usage data or device identifiers to third parties.
4. Data Storage and Protection
- Strictly Local Storage: All your custom tension parameters, stringing presets, and connection preferences reside exclusively in your local iOS sandbox and are never uploaded to remote cloud servers.
- Communication Security: Data transmission between the iPhone and the stringing machine is carried out over proprietary BLE protocols to ensure command integrity.
- Data Deletion: Because all data is stored locally, uninstalling or deleting the App from your iOS device will instantly and permanently erase all saved presets and records.
5. Your Rights and Choices
- Permission Control: You can manage or revoke Bluetooth permissions at any time via iOS Settings > Privacy & Security > Bluetooth (or Settings > Pusun Stringing Machine). Revoking permission will disconnect the hardware but does not affect normal iOS functionality.
- No Deletion Request Required: Since we do not collect personal profiles or maintain cloud accounts, there is no account deletion procedure required. Uninstalling the app completely removes all data.
6. Children's Privacy
The App serves as a physical sports equipment utility and does not contain content directed at children:
- We do not knowingly collect personal information from children under the age of 14.
- Stringing machines involve high-tension mechanical components. Minors operating the physical hardware should always do so under adult supervision.
7. Policy Changes and Updates
We may update this Privacy Policy to reflect firmware enhancements or regulatory changes. Material updates will be reflected in the "Last Updated" date at the top of this page or announced within app update release notes.
