1. Introduction
This Privacy Policy applies to AI Video & Audio Converter, a mobile application provided by Xingtao (Wuhan) Technology Co., Ltd. ("we", "us" or "our"). The app provides video format conversion, audio format conversion, video trimming, audio trimming, video compression, video-to-audio conversion, and natural-language task generation for video or audio processing.
We are committed to handling user information responsibly and transparently. By using the app, you acknowledge that your information may be processed as described in this Privacy Policy.
2. Media Files You Select
The app may process media files that you choose, including videos, audio files, images and related file metadata. These files are selected by you for conversion, trimming, compression, extraction or other supported processing tasks.
Media processing is mainly performed locally on your device. We do not automatically upload your selected media files to our servers unless you actively use an AI feature, a cloud/upload feature, or another feature that clearly requires transmission.
3. Information We May Collect or Process
Information processed for core media functions
- Media files selected by you, such as videos, audio files and images.
- Basic file information, such as file type, duration, size, format and processing settings.
- Processing results generated on your device, such as converted or trimmed files.
Information processed when you use AI or upload features
If you actively use AI features or upload features, some information may be sent to our servers or relevant service infrastructure to generate a processing plan, perform requested processing, limit the number of free daily uses, maintain service availability and troubleshoot issues. This information may include:
- Natural-language text instructions entered by you.
- Task type, task status, processing parameters and server response status.
- Device identifiers or app-generated identifiers used for service operation and daily free-use limits.
- Error logs, crash information, diagnostic events and technical data needed to identify problems.
- Uploaded media files when the feature you choose requires cloud-side processing or upload.
4. How We Use Information
We use the information described above for the following purposes:
- To provide video and audio conversion, trimming, compression and extraction functions.
- To generate video or audio processing tasks from your natural-language instructions.
- To operate AI features, upload features and related server-side services.
- To limit daily free usage, prevent abuse and maintain fair use of service resources.
- To identify errors, improve stability, troubleshoot issues and maintain app security.
- To comply with applicable laws, regulations and platform requirements.
5. Information We Do Not Collect
We do not collect the following categories of sensitive information:
- Contacts or address book data.
- SMS messages.
- Call logs.
- Precise location data.
- Health data.
- Financial data.
We do not sell user data.
6. Data Sharing
We do not sell your personal information or media files. We may share limited information only when it is necessary to provide the app's functions, operate server-side services, comply with legal obligations or protect the rights, safety and security of users, our company or the service.
When AI or upload features require server-side infrastructure, the information needed to complete the requested task may be processed by our servers or service providers acting on our behalf.
7. Data Retention
Locally processed media files remain on your device unless you choose to export, share, upload or delete them. Server-side task records, device identifiers, logs and uploaded content are retained only for as long as reasonably necessary to provide the requested service, enforce free-use limits, troubleshoot problems, maintain security or comply with legal requirements.
8. Security
We use reasonable technical and organizational measures designed to protect information processed by the app. However, no method of transmission or storage is completely secure. You should avoid uploading or processing files that contain highly sensitive information unless you understand and accept the related risks.
9. Your Choices
- You may choose which media files to process in the app.
- You may avoid using AI or upload features if you do not want related information sent to servers.
- You may delete local output files using your device's file management tools or app controls.
- You may contact us to ask questions about this Privacy Policy or request support.
10. Children's Privacy
AI Video & Audio Converter is not directed to children. We do not knowingly collect personal information from children. If you believe that a child has provided information to us, please contact us and we will take appropriate steps in accordance with applicable law.
11. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes in the app, legal requirements or our practices. The updated version will be posted on this page with a revised effective date.
