1.Introduction

Suzhou Lingqiaojiang Technology Co., Ltd. ("we", "us" or "our") takes your privacy and the protection of your personal information seriously. This Privacy Policy applies to your use of the Audify iOS app (the "App") and its services, including audio editing, format conversion, sound effects processing and recording.

Please read this Policy carefully before using the App. By using or continuing to use the App, you agree that we may handle your information as described in this Policy.

The App does not require you to register or sign in, contains no ads, and does not integrate any third-party analytics, advertising or tracking SDKs. We do not access your device's advertising identifier (IDFA), and we do not track you across other apps or websites.

2.How We Handle Your Information

2.1 On-device processing (nothing is uploaded)

Trimming and editing, speed and pitch changes, voice effects, reverb and EQ, mixing, recording, merging, splitting, ringtone creation and most format conversions are performed entirely on your device. Your audio files never leave your device, and we have no access to them.

2.2 Cloud processing (uploaded only when you choose to use it)

The following features require the audio file you select to be uploaded to our servers for processing:

• AI Noise Reduction;
• Vocal Separation;
• Exporting to formats that require server-side encoding, such as MP3 / OGG.

Uploaded files are used solely to complete the processing you requested. Once the result has been downloaded to your device, both the original file and the result on our server are automatically deleted within 60 minutes. We do not view, analyze, retain, or use these files for any other purpose, including model training.

2.3 Feedback

When you submit feedback via "Settings → Feedback", we collect the name, contact information (phone number or email address) and feedback content you choose to provide, as well as your IP address at the time of submission. This information is used only to respond to your feedback, improve the App and prevent abusive submissions.

2.4 Service logs

When you use cloud features, our servers automatically record necessary access logs (such as IP address, request time and the endpoint requested) to keep the service secure and to troubleshoot issues. These logs are not linked to your identity.

3.Device Permissions We Request

• Microphone: Requested only when you use the Recorder feature, to record audio. Recordings are saved on your device. Declining this permission does not affect other features.
• Photos (video picker): When you use features such as "Extract Audio from Video", the App reads only the videos you select through the system photo picker. The App cannot access any photos or videos you have not selected.
• Files: Used to import audio or video files you select through the system Files app. The App also lets you access its folder via the Files app or a computer so you can manage your exported files.
• Network: Used for cloud processing and for submitting feedback.
• Background audio: Used to continue playing or recording audio while the App is in the background or the screen is locked.

You can enable or disable these permissions at any time in iOS "Settings → Privacy & Security".

4.Data Storage

• On-device storage: Your audio library, exported files and preferences such as language are stored only in the App's sandbox. You can clear the cache in "Settings → Storage"; uninstalling the App deletes all of this data.
• Server storage: Our servers are located in the People's Republic of China. Files uploaded for cloud processing are automatically deleted within 60 minutes. Feedback information is kept for no more than 3 years after it has been handled, or for the period required by applicable laws and regulations.
• We do not transfer your personal information outside the People's Republic of China.

5.Sharing, Transfer and Public Disclosure

We do not sell your personal information, and we do not share, transfer or publicly disclose it to any third party, except in the following cases:

• With your prior explicit consent;
• As required by laws and regulations, legal proceedings, or mandatory requests from competent government authorities;
• Processing on our behalf: To improve the quality of AI Noise Reduction and Vocal Separation, we may engage Alibaba Cloud Computing Co., Ltd. (Intelligent Media Services and Object Storage Service, OSS) to process the audio you upload. Alibaba Cloud processes it only according to our instructions, may not use it for any other purpose, and the related temporary files are deleted once processing is complete. Feedback notification emails are sent via Alibaba Cloud Enterprise Mail.

6.Information Security

All data transmitted between the App and our servers is encrypted using HTTPS. We protect your information through access controls, data minimization and regular automatic deletion. However, no internet environment is completely secure. In the unlikely event of a personal information security incident, we will notify you promptly and report to the competent authorities as required by law.

7.Your Rights

• Access, correction and deletion: You can manage or delete on-device data directly in the App. To access, correct or delete feedback information you have submitted, please contact us using the details at the end of this Policy.
• Withdrawing consent: You can turn off the relevant permissions in system settings or stop using cloud features. Withdrawing consent does not affect processing carried out before the withdrawal.
• Account deletion: The App has no account system. Uninstalling the App removes all of its data from your device.

We will respond to your request within 15 business days of receiving it.

8.Children's Privacy

If you are under the age of 14, please read this Policy with the guidance of your parent or guardian, and use the App only with their consent. If a parent or guardian discovers that we have processed a minor's personal information without consent, please contact us and we will delete it as soon as possible.

9.Changes to This Policy

We may update this Policy as the App's features change or as required by laws and regulations. The updated Policy will be posted on this page. For material changes, we will notify you prominently within the App.
