**Last Updated:** January 14, 2026

We recognize the importance of your personal information and are committed to handling it in accordance with the principles of lawfulness, fairness, necessity, good faith, and transparency.

This Privacy Policy explains how we collect, use, share, and protect your personal information, as well as the rights you have regarding your data.

**Key Principles:** We follow the principles of data minimization and purpose limitation. If we need to change the purposes, methods, or scope of data processing, we will obtain your consent again.

## 1. Information We Collect

We may collect the following categories of information:

- **Account Information:** Identifiers provided through Sign in with Apple or WeChat Login.
- **Training Data:** Training ends, arrow counts, scores, arrow impact coordinate snapshots, statistical analysis results, and related training records.
- **Device and Log Information:** Device model, operating system version, unique device identifiers, network information, crash reports, and performance data.
- **Media Information:** Profile pictures and training-related images accessed with your permission, used for profile customization, generating training posters, and related features. Denying permission will not affect core training functionality.
- **Local Cache and Settings:** Target face types, bow types, shooting distances, training modes, and other configuration preferences.
- **Error and Performance Diagnostics:** Crash stack traces, error messages, performance metrics, device and application environment information (including IP addresses), interaction breadcrumbs, and navigation events.
- **Session Replay Data:** Interface and interaction events used to reproduce and diagnose issues. Session replay is subject to limited sampling by default, which may increase when errors occur. Sensitive areas are masked.
- **User Feedback:** Information you voluntarily submit through feedback forms, along with basic diagnostic context.

- **Permanent Hardware Identifiers:** We do not collect IMEI, IMSI, MAC addresses, device serial numbers, or similar permanent hardware identifiers.
- **Clipboard:** We do not proactively access clipboard contents unless you explicitly paste information into the application.

If future functionality requires processing any of the above information, we will obtain your explicit consent separately and update this Privacy Policy accordingly.

## 2. How We Use Your Information

We use collected information for the following purposes:

- **Service Delivery and Improvement:** To provide, maintain, and optimize application functionality, including training records, statistical summaries, charts, and performance analysis.
- **Account and Service Security:** To authenticate users, detect unusual activity, troubleshoot issues, and track errors.
- **Diagnostics and Performance Optimization:** To identify technical problems, improve application performance, and enhance service quality. This information is not used for personalized advertising.
- **Permission-Based Features:** To perform specific actions with your authorization, such as taking photos or saving training posters to your photo library.
- **Legal Compliance:** To comply with applicable laws, regulatory requirements, and lawful requests from judicial authorities.

Permissions are requested only when you use the corresponding features. You can manage or revoke permissions through your device's system settings.

## 4. Third-Party Sharing and Data Processing

Where necessary to provide our services, we may share limited personal information with third parties or engage third-party service providers to process information on our behalf, such as for account authentication, cloud storage, and analytics.

We limit such sharing and processing to the minimum information necessary for the specified purposes.

**Important:** All third-party SDKs are activated only after you have agreed to this Privacy Policy. No third-party SDK will collect information before your consent.

The application integrates the following third-party services:

Where separate consent is required by law, we will provide a clear notice within the application and obtain your authorization before the transfer.

## 6. Data Storage and Security

- **Storage Location:** Personal information is stored in compliance with applicable laws and regulations.
- **Retention Period:** We retain personal information only for the minimum period necessary to fulfill its intended purposes. Once the retention period expires, information will be deleted or anonymized unless otherwise required by law.
- **Security Measures:** We implement encrypted data transmission, access controls, least-privilege permissions, log auditing, backup, and recovery mechanisms to protect user information.

Diagnostic and session replay data are generally retained for no more than 90 days (or according to the actual service configuration). After the applicable retention period, such data will be automatically deleted or anonymized.

We also employ encryption in transit and at rest, access controls, and sensitive-area masking to enhance data protection.

## 7. Your Rights

- **Deletion and Withdrawal of Consent:** You may request the deletion of training data or withdraw previously granted permissions.
- **Account Deletion:** You may request account deletion through **Profile > Account Settings > Delete Account**, or an equivalent option within the application.

Upon receiving an account deletion request, we will verify your identity and process the request within a reasonable period. Once your account is deleted, associated personal information will be deleted or anonymized in accordance with applicable laws, except where retention is legally required.

You may disable error tracking and session replay through **Settings > Privacy & Security** (available after the feature is released). Once disabled, no new related diagnostic or replay data will be uploaded.

Following account deletion, we will also delete or anonymize diagnostic data associated with your account, except where legal retention obligations apply.

We will respond to requests concerning your personal information within the time limits required by applicable law. However, certain requests may be restricted where they affect the rights of others or conflict with legal requirements.

If a parent or guardian believes that we have inadvertently collected a child's personal information, they may contact us to request its deletion or withdraw consent.
