Privacy Policy

Effective November 12, 2026

This policy explains what information the SoundLab app (called “合声” in mainland China) and this website collect, how it is used, and the choices you have. SoundLab is published by Wuhan BigTool365 Technology Co., Ltd. (“we”, “us”).

  • Your audio stays on your device. Editing, recording, AI separation and noise reduction run on your iPhone or iPad. We never receive your recordings, projects or files.
  • No account. SoundLab does not ask for your name, email address or phone number.
  • Limited technical data. We collect device and usage information to run the app, measure our marketing and fix problems. We do not sell personal information.
  • Tracking only with your permission. Advertising identifiers are used only if you allow tracking in Apple’s prompt.

1. Information that stays on your device

Your audio files, recordings, projects, the text you turn into speech, and the images you choose as cover art are stored on your device. If you use iCloud, they are also stored in your own iCloud account, which Apple operates. We cannot access any of this.

SoundLab asks for these permissions only when you use the related feature. You can change them at any time in the Settings app.

Wi-Fi transfer sends files directly between your devices on your local network. Text-to-speech uses Apple’s speech engine on your device.

2. Information we collect

2.1 App and device information

When SoundLab starts, it connects to our server (biz.soundlab.cloud, hosted by Cloudflare) and sends:

Our server works out your country from your IP address. The IP address itself is used only to protect the server from abuse and is not stored. We use this information to operate the app’s online functions, to decide which diagnostics a device should run, to prevent abuse, and to produce aggregate statistics.

2.2 Diagnostic data

To investigate specific problems, we may turn on diagnostics for a limited number of devices. When diagnostics are on, the app sends technical measurements such as:

Diagnostic data never includes file names, folder names, project or track names, audio content, contacts or location. It is deleted automatically after 30 days.

2.3 Usage analytics

We use Google Analytics for Firebase to understand which features are used and where the app needs improvement. It receives app events (for example, that an export finished or a feature was opened), an app-instance identifier, device and app information, basic purchase events, and an approximate location derived from your IP address.

2.4 Install and purchase measurement

We use AppsFlyer to learn which campaigns, such as Apple Search Ads, bring people to SoundLab. It receives your IP address, device and app information, the identifier for vendor, install and open events, and purchase events (product, price and currency). It receives the advertising identifier (IDFA) only if you allow tracking.

2.5 Purchases

Apple processes all payments. We never receive your payment card or billing details. We receive information about your transactions from Apple, such as the product, purchase date, subscription status and transaction ID, so that we can unlock and restore SoundLab Pro.

2.6 Feedback and support

If you contact us, for example through the Feedback option in the app, we receive your email address, your message and any attachments you choose, together with the technical details the app adds to the message, such as device model and app version. Feature requests on our feedback board (soundlab.nolt.io) are handled by Nolt under its own privacy policy.

2.7 This website

This website does not use cookies or analytics. Cloudflare, which hosts it, processes request data such as IP addresses to deliver and protect the site.

3. Tracking and your choice

SoundLab shows Apple’s App Tracking Transparency prompt. If you allow tracking, AppsFlyer and Google Analytics may receive your device’s advertising identifier to measure our advertising. If you do not allow it, the advertising identifier is not accessed. You can change this at any time in Settings > Privacy & Security > Tracking. SoundLab does not show ads.

4. How we use information

We do not use your information to make decisions that have legal or similarly significant effects on you.

5. Sharing

We do not sell personal information. We share it only with service providers that process it for us under contract, and only for the purposes in this policy:

We may also disclose information if the law requires it, to protect the rights and safety of our users or others, or as part of a merger or acquisition, in which case this policy continues to protect it.

6. How long we keep information

7. Your rights and choices

Depending on where you live, you may have the right to access, correct, delete or obtain a copy of your personal information, to object to or restrict its use, and to withdraw consent. To make a request, email us at the address below. Because SoundLab has no accounts, we may ask for details that help us locate the data from your device.

If you are in the European Economic Area or the United Kingdom, we rely on these legal bases: performing our contract with you (providing the app and purchases), our legitimate interests (security, diagnostics and improving the app), and your consent (tracking). You can also complain to your local data protection authority.

8. Security

Information is sent over encrypted connections, and access to our server data is limited to the people who need it to run and improve SoundLab. No method of transmission or storage is completely secure, but we work to protect your information.

9. International transfers

Our server runs on Cloudflare’s global network, and Google and AppsFlyer may process information in the United States and other countries. Where required, these transfers are protected by appropriate safeguards such as standard contractual clauses.

10. Children

SoundLab is not directed to children under 13 (under 14 in mainland China), and we do not knowingly collect their personal information. If you believe a child has provided personal information to us, contact us and we will delete it.

11. Changes to this policy

We will post any changes on this page and update the effective date. If a change is significant, we will also give notice in the app or on this website.

隐私政策

生效日期:2026 年 11 月 12 日

本政策说明 SoundLab 应用(在中国大陆名为“合声”)和本网站收集哪些信息、如何使用,以及你可以做出的选择。SoundLab 由Wuhan BigTool365 Technology Co., Ltd.(以下简称“我们”)发布。

  • 你的音频留在你的设备上。编辑、录音、AI 分离和降噪都在你的 iPhone 或 iPad 上完成。我们不会收到你的录音、工程或文件。
  • 无需账号。SoundLab 不会要求你提供姓名、电子邮箱或手机号码。
  • 只收集有限的技术数据。我们收集设备和使用信息,用于运行应用、衡量推广效果和修复问题。我们不出售个人信息。
  • 经你同意才会跟踪。只有你在 Apple 的提示中允许跟踪,才会使用广告标识符。

一、留在你设备上的信息

你的音频文件、录音、工程、用于文字转语音的文字,以及你选作封面的图片,都保存在你的设备上。如果你使用 iCloud,它们还会保存在你自己的、由 Apple 运营的 iCloud 账户中。我们无法访问这些内容。

SoundLab 只在你使用相关功能时才申请以下权限,你可以随时在“设置”中更改:

Wi-Fi 传输在你的设备之间通过本地网络直接传送文件。文字转语音使用设备上的 Apple 语音引擎。

二、我们收集的信息

2.1 应用和设备信息

SoundLab 启动时会连接我们的服务器(biz.soundlab.cloud,由 Cloudflare 托管),并发送:

服务器会根据你的 IP 地址判断所在国家或地区。IP 地址本身只用于防止服务器被滥用,不会被保存。我们使用这些信息来运行应用的联网功能、决定设备运行哪些诊断、防止滥用,以及生成汇总统计。

2.2 诊断数据

为排查具体问题,我们可能会在少量设备上开启诊断。开启后,应用会发送以下技术测量数据:

诊断数据不包含文件名、文件夹名、工程或音轨名称、音频内容、通讯录或位置。诊断数据在 30 天后自动删除。

2.3 使用统计

我们使用 Google Analytics for Firebase 了解哪些功能被使用、哪些地方需要改进。它会收到应用事件(例如导出完成、打开了某个功能)、应用实例标识符、设备和应用信息、基本的购买事件,以及根据 IP 地址推断的大致位置。

2.4 安装和购买归因

我们使用 AppsFlyer 了解哪些推广渠道(例如 Apple 搜索广告)带来了用户。它会收到你的 IP 地址、设备和应用信息、供应商标识符(IDFV)、安装和启动事件,以及购买事件(商品、价格和币种)。只有在你允许跟踪时,它才会收到广告标识符(IDFA)。

2.5 购买

所有付款都由 Apple 处理。我们不会收到你的银行卡或账单信息。我们会从 Apple 获得交易信息,例如商品、购买日期、订阅状态和交易 ID,用于解锁和恢复 SoundLab Pro。

2.6 反馈与支持

如果你联系我们(例如通过应用里的“反馈”),我们会收到你的电子邮箱、你的留言和你选择的附件,以及应用附加在邮件中的技术信息,例如设备型号和应用版本。反馈看板(soundlab.nolt.io)上的功能建议由 Nolt 按其隐私政策处理。

2.7 本网站

本网站不使用 Cookie,也不使用统计分析。托管本网站的 Cloudflare 会处理 IP 地址等请求数据,用于提供和保护网站。

三、跟踪与你的选择

SoundLab 会显示 Apple 的“App 跟踪透明度”提示。如果你允许跟踪,AppsFlyer 和 Google Analytics 可能会收到设备的广告标识符,用于衡量我们的广告效果。如果你不允许,应用不会访问广告标识符。你可以随时在“设置 > 隐私与安全性 > 跟踪”中更改。SoundLab 不展示广告。

四、我们如何使用信息

我们不会利用你的信息作出对你产生法律影响或类似重大影响的自动化决定。

五、共享
