Privacy Policy

Last Updated: March 25, 2026

Welcome to SubPlayer (hereinafter referred to as "the App"). We value your privacy and strive to handle data in a transparent, necessary, and minimal manner. This policy explains: the types of information the App may process when you use its features, how such information is used, and how you can manage and delete related data.

1. Scope of Application

This policy applies to data processing activities when you use features such as local media browsing, remote connections, online playback, in-app transactions, and related functionalities through the App.

2. What Information We Process and How We Use It

During your use of the App, we may process the following types of information based on the features you enable, device permissions you grant, and your actual operations. Some information is processed and stored only on your device and is not uploaded to our servers; when you actively use online features, data directly related to those features will be sent to the corresponding services only to the extent necessary.

• Information you actively provide or configure: For example, connection details you add, file resources you choose to access or manage, and information you submit when using transactions, memberships, or other online services, used to provide the relevant features and respond to your actions.
• Information processed and stored only on your device: For example, playback progress, browsing history, favorites, download records, preference settings, cache, on-device identifiers, and local login status, used to save usage state, maintain continuity of experience, and support troubleshooting. Such information is stored locally on your device by default and is not collected online by us.
• Information required for online features: When you actively use remote connections, authentication, transaction verification, entitlement synchronization, or other online features, the App may send device information, app and version information, session or identity identifiers, transaction-related credentials, and other data necessary to complete the corresponding features to the relevant services, for the purposes of providing services, verifying identity or entitlements, ensuring security, and complying with legal requirements.

We follow the principle of minimum necessity when processing the above information, primarily using it to provide core features, ensure service security, maintain service and transaction status, improve product experience, and comply with legal requirements.

3. Subtitle Generation

The App provides an automatic subtitle generation feature. When you use this feature:

• The App extracts audio segments from the video and sends them to our server for processing.
• Subtitle generation is performed entirely on our own servers. Your audio data is never forwarded to or shared with any third party.
• Our server uses the Qwen3-ASR-Flash model for speech recognition to generate corresponding subtitle files.
• Audio data is used solely for subtitle generation purposes. It is deleted immediately upon completion of processing, and we do not retain your audio data.
• The generated subtitle files are returned to your device for local storage. No subtitle content is retained on the server.
• If you do not use this feature, no audio data will be extracted or uploaded.

4. Device Permissions and Local Resource Access

• Photo Library / Media Library Permission: When you browse videos, audio, or photo library content on your device, the App will request the corresponding permissions. You can grant full access, limited access, or deny authorization.
• File and Directory Access: When you actively select local files, document directories, or download locations, the App only accesses the corresponding files or directories within the scope of your authorization.
• Permission Revocation: You can revoke the above permissions at any time in your device's system settings. After revocation, the related features may no longer be available.

5. Data Sharing and Third-Party Services

We do not sell your personal information. Only to the extent necessary to provide services, complete transactions, or fulfill legal obligations, will we provide data to the following categories of third parties or external services:

• Services you actively designate or connect to: When you use related online features, the App will communicate with servers, devices, or network services that you have configured or designated, in accordance with your actions.
• Transaction and payment-related service providers: When you use transactions, payments, order verification, entitlement synchronization, or similar services, related data may be provided to app distribution platforms, payment processors, or transaction verification service providers.
• Legal requirements or rights protection: When required by laws and regulations, legitimate requests from regulatory authorities, or when necessary to protect the legitimate rights and interests of us, users, and the public.

For third-party service providers who access user data pursuant to law or to provide related services, we require them to process the related data with protective measures no less stringent than those described in this policy.

6. Data Storage and Retention

Unless otherwise required by laws, regulations, or regulatory authorities, we only store your personal information for the minimum period necessary for the purposes described in this policy.

If we cease services or operations, we will promptly stop collecting your personal information, notify you in advance in accordance with applicable legal requirements, and delete or anonymize your personal information after the termination of services or operations, unless otherwise required by laws, regulations, or regulatory authorities.

7. Data Security

We have comprehensive encryption and security mechanisms to prevent the leakage of your personal information. We have adopted industry-standard technical and administrative measures to protect the security of your data:

• Local configurations and records are stored in your device's local storage by default and are protected by system-level security.
• Network communications with online services are transmitted through encrypted protocols such as HTTPS to ensure the confidentiality of data during transmission.
• We take reasonable technical and administrative measures to reduce the risk of unauthorized access, disclosure, or misuse, but please understand that no system can guarantee absolute security.

8. Your Rights and Choices

• You can revoke permissions for photo library, file access, and similar authorizations in your device's system settings.
• You can stop using related online features; when you do not use such features, the corresponding data will generally not be sent to our services.
• If you wish to delete server-side records related to online services, or submit a data processing request, you can contact us through the contact information provided in this policy. To protect account and device security, we may need you to provide necessary information to verify the request.

9. Protection of Minors

The App is not designed for children under the age of 13, and we do not knowingly collect personal information from children under 13. If a guardian discovers that a minor has provided personal information to us without consent, please contact us through the contact information in this policy, and we will handle it in accordance with the law after verification.
