Data involved
Device advertising data (device name, RSSI signal strength, MAC address), Bluetooth UUID
Purpose
Identify and connect to the target BLE device
Method
Local BLE scanning and connection via the iOS CoreBluetooth framework
Scope
Only user-initiated scans; results are displayed only within this App's interface
Storage location
Not stored; scan results are kept in memory only and released when leaving the page
Cross-border transfer
None; all data is processed locally on the device
Required Permissions
| Permission | Purpose | Method | Scope |
|---|
| Bluetooth access | Scan and connect to BLE devices | System Bluetooth API | When using the scan feature |
| Background Bluetooth | Keep the device connection in the background | System background Bluetooth mode | During OTA updates |
⬆️Feature 2: Firmware File Import and OTA Update
The user selects a firmware file (.bin / .hex / .hex4 / .hex16 / .res) and transfers it to the target device via Bluetooth to perform a firmware update.
Data involved
The imported firmware file, target device firmware version, chip PID/VID identifiers
Purpose
Write firmware data to the target BLE device to complete the update
Method
Import the file via iOS file sharing (Document Picker), then transfer the firmware data via the BLE protocol (SLB/SBK)
Scope
Only user-selected files; communicates only with the user-selected target device
Storage location
Firmware files are temporarily stored in the App's Documents directory solely for the update task; device version information is kept in memory only
Cross-border transfer
None; all data is processed locally on the device
Retention
Firmware files can be manually deleted by the user after the update; automatically cleared by the system on uninstall
Required Permissions
| Permission | Purpose | Method | Scope |
|---|
| File access | Pick firmware files from the device | iOS Document Picker | When the user taps "Select File" |
🏷️Feature 3: Device Alias Management
The user can set a custom alias for a connected Bluetooth device for easier identification and management of multiple devices.
Data involved
The user-entered custom alias (associated with the device Bluetooth UUID)
Purpose
Quickly identify a specific device among a large number of devices
Method
The user enters an alias via a dialog; the App associates it with the device UUID and saves it
Scope
Used only within this App, solely for device list display
Storage location
iOS device local UserDefaults
Cross-border transfer
None; stored locally on the device only
Retention
The user can swipe left on a device entry to delete the alias; all data is automatically cleared on uninstall
📝Feature 4: Bluetooth Interaction Log
Records communication logs between the App and BLE devices (commands sent/received, device events, etc.) for technical debugging.
Data involved
BLE communication command content, timestamps, device name/UUID, operation results
Purpose
For developers and technicians to debug Bluetooth communication issues
Method
The SDK records automatically during operation; the App layer collects and displays them
Scope
Viewable only in the "Interaction Log" page within this App
Storage location
iOS device local UserDefaults (OTASDKDemo project only); not persisted at the SDK layer
Cross-border transfer
None; stored locally on the device only
Retention
The user can clear logs at any time on the log page; automatically cleared on uninstall
🧪Feature 5: Stress / Burn-in Testing
Performs continuous repeated OTA update tests on BLE devices to verify device stability and reliability. (Applicable to the iOS_PHYOTA_Test project only)
Data involved
Test configuration parameters (test count, interval, etc.), test result statistics (success/failure counts, duration)
Purpose
Batch verification and reliability testing of devices in production or laboratory environments
Method
The user configures test parameters, then the App automatically loops through the OTA process and records results
Scope
Test results are displayed only within this App
Storage location
iOS device local UserDefaults
Cross-border transfer
None; stored locally on the device only
Retention
The user can clear test records; automatically cleared on uninstall
🗂️Storage Period
All data in this App is stored locally on the device. Retention follows these principles:
| Data type | Retention period | Description |
|---|
| Bluetooth scan data | Not stored | Kept in memory only; released when leaving the page or stopping the scan |
| Firmware files | Until the user deletes or uninstalls | Temporarily kept solely for the OTA update; no automatic expiration |
| Device alias | Until the user deletes or uninstalls | Retained until manually deleted by the user; no automatic expiration |
| BLE interaction log | Until the user clears or uninstalls | For debugging only; recommend clearing promptly after debugging |
| Stress test records | Until the user clears or uninstalls | For test verification only |
Retention principle: Since this App does not collect personally identifiable information and no data is transmitted over the network, data serves only the user's local usage needs. Therefore, retention is controlled by the user — the user may delete any data at any time, and uninstalling the App clears all data. We do not set automatic expiration for data, because we have no right to, and will not, remotely modify data on your device without your knowledge.
The ultimate means to achieve "storage minimization": uninstall this App, and iOS will automatically delete all App-related data.
🤝Sharing of Personal Information with Third Parties
This App does not share any user personal information with any third party. Specifically:
Types of shared personal info
None
Third-party SDK Integration
This App does not integrate any third-party SDKs (including but not limited to analytics, advertising, location, social sharing, crash collection, and payment SDKs). It does not share, transfer, or publicly disclose user data to any third party.
🔒Data Security
All data is stored only on your device. This App does not perform any network communication, so there is no risk of data being intercepted during transmission. We recommend protecting local data via the iOS device encryption and lock screen passcode.
Sensitive Personal Information
This App does not collect any sensitive personal information. Under China's Personal Information Protection Law, sensitive personal information includes biometric data, religious beliefs, specific identity, medical and health information, financial accounts, location tracking, and the personal information of minors under fourteen. This App processes only technical data necessary for Bluetooth firmware updates (BLE device MAC address, firmware version, device alias, communication logs), none of which falls into the category of sensitive personal information.
This App does not involve photo capture, audio recording, screen recording, or location tracking, and does not request permissions for camera, microphone, location, contacts, or photo library.
This App does not perform any data mining, user profiling, or behavioral analysis, integrates no analytics or statistics SDK, and performs no network communication.
Children's Privacy
This App is a professional firmware update tool for engineering and technical staff. It is not intended for children under 13, and it does not knowingly collect children's personal information.
Policy Changes
When the purpose, method, or scope of personal information processing changes, we will update this Privacy Policy in a timely manner and notify you as follows:
- Updating the content in the App's "Settings" → "Privacy Policy" page and marking the new effective date at the top of the page;
- For major changes (such as new types of data collection or changes in data usage), we will remind you in-app via a popup or other prominent means to read the updated Privacy Policy, and re-obtain your consent where necessary.
We recommend reviewing this Privacy Policy regularly to stay informed of the latest personal information processing rules.
