Privacy Policy

1. Overview

We value your privacy and are committed to handling personal information responsibly. This Privacy Policy applies to your access to and use of VznGPT, including related account functions, device pairing, network configuration, diagnostics, and support services. Please read this Policy carefully so that you understand what information we collect, why we collect it, and the choices available to you.

2. Information We Collect

Depending on how you use the App and related devices, we may collect the following categories of information:

Account Information, such as your email address, login credentials, and authentication identifiers.
Device Information, such as device name, device identifier, firmware version, model information, pairing records, and connection status.
Usage Information, such as feature interactions, operation logs, crash logs, error codes, and app activity records.
Technical Information, such as IP address, app version, operating system, language settings, device type, and network environment information.
Support Information, such as information you voluntarily provide when contacting customer support, reporting issues, or submitting feedback.

3. How We Use Information

We may use the information we collect for the following purposes:

To register and manage user accounts and maintain login sessions.
To provide device discovery, pairing, connection, configuration, and management functions.
To enable QR code scanning, Bluetooth Low Energy (BLE) communication, Wi-Fi configuration, and related setup processes.
To maintain service quality, troubleshoot technical issues, and improve product performance and stability.
To protect the security of the App, related devices, users, and systems, including detection and prevention of abuse, fraud, unauthorized access, or other harmful activities.
To respond to inquiries, feedback, complaints, or support requests.
To comply with applicable legal obligations, regulatory requirements, or lawful requests.

4. Permissions and Device Access

To deliver core functionality, the App may request access to certain device permissions and hardware capabilities. For example, camera access may be used for scanning QR codes, Bluetooth access may be used for discovering and connecting to nearby devices, and certain Android location permissions may be required by the operating system for BLE scanning. We request only the permissions reasonably necessary to provide relevant functions.

5. Sensitive Information and Network Configuration

Some device setup scenarios may involve sensitive operational data. We take reasonable steps to reduce privacy and security risk, including:

Using secure transmission methods during device communication and configuration where applicable.
Limiting the use of Wi-Fi credentials or similar setup data to the connection and provisioning process.
Avoiding unnecessary retention of highly sensitive setup information within the App where not required for service delivery.
Applying session-based or temporary security measures where supported by the underlying technology.

6. How We Share Information

We do not sell your personal information. We may share information only in limited circumstances, including:

With service providers, contractors, or technical vendors that support account services, hosting, storage, analytics, security, or customer support, subject to appropriate obligations.
With affiliated entities where necessary for internal administration, product maintenance, or support operations.
Where required by applicable law, regulation, legal process, or government request.
Where necessary to protect the rights, property, safety, or security of our company, users, devices, services, or others.
In connection with a merger, acquisition, financing, restructuring, sale of assets, or similar corporate transaction, subject to applicable legal requirements.

7. International Data Transfers

Depending on the architecture of our services and vendors, your information may be processed, accessed, or stored in jurisdictions outside your country or region. In such cases:

We will take reasonable steps to ensure that transferred information is handled with appropriate safeguards.
You understand that data protection rules in other jurisdictions may differ from those in your place of residence.
By using the App where permitted by law, you acknowledge that your information may be transferred and processed across borders for the purposes described in this Policy.

8. Data Retention

We retain information only for as long as reasonably necessary to fulfill the purposes described in this Policy, including providing services, maintaining account functionality, resolving disputes, enforcing agreements, complying with legal obligations, and protecting security. Retention periods may vary depending on the type of information and the context in which it is collected.

9. Data Security

We implement reasonable technical, administrative, and organizational measures designed to protect personal information against unauthorized access, loss, misuse, alteration, or disclosure. However, no software, device environment, network transmission, or storage system can be guaranteed to be completely secure, and you should also take appropriate steps to protect your own account credentials and devices.

10. Your Choices and Controls

You may choose whether to provide certain information, although some features may not function properly without it. You may also manage permissions through your device settings, stop using the App at any time, or contact us regarding account-related requests.

13. Third-Party Services

The App may rely on third-party technologies or infrastructure providers to support authentication, cloud storage, analytics, crash reporting, or other technical functions. These third parties may process data on our behalf in accordance with contractual or legal obligations.
