SoundLabPrivacy Policy
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.
- Microphone: to record audio.
- Media & Apple Music: to import songs from your music library.
- Photos: to choose cover art or a picture for a feedback message, and to save exported videos.
- Camera: to take a picture for a feedback message.
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:
- device model, iOS version, app version and build number;
- your language and region setting;
- a random installation ID, and a device ID that SoundLab derives from Apple’s identifier for vendor;
- an app-specific iCloud user identifier that Apple issues to SoundLab. It does not reveal your Apple Account, name or email address;
- your purchase status, for example free, subscribed or lifetime.
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:
- audio settings and the type of output in use, for example sample rates and whether Bluetooth headphones are connected;
- the format of imported audio, such as sample rate, channels and duration, and any error codes;
- a summary of the app’s storage use: total sizes and file counts of the app’s own folders.
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
- to provide the app, unlock purchases and keep your purchase status correct;
- to find and fix bugs, crashes and audio problems;
- to understand how features are used and improve them;
- to measure the effectiveness of our marketing;
- to answer your messages;
- to keep our services secure and meet legal obligations.
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:
| Provider | Purpose | Information | Privacy policy |
|---|---|---|---|
| Google Analytics for Firebase (Google LLC) | Usage analytics | App-instance identifier, identifier for vendor, device model, iOS and app version, language, approximate location, app events, purchase events; advertising identifier only if you allow tracking | firebase.google.com/support/privacy |
| AppsFlyer SDK (AppsFlyer Ltd.) | Install and purchase measurement | IP address, identifier for vendor, device model, iOS and app version, install, open and purchase events, Apple Search Ads attribution data; advertising identifier only if you allow tracking | appsflyer.com/legal/services-privacy-policy |
| Cloudflare, Inc. | Hosting our server and this website | Information in sections 2.1, 2.2 and 2.7 | cloudflare.com/privacypolicy |
| Apple Inc. | Payments, iCloud storage | Handled under Apple’s own terms; we receive only the transaction information in section 2.5 | apple.com/legal/privacy |
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
- Diagnostic data: 30 days, then deleted automatically.
- App and device information on our server: as long as needed for the purposes above, and deleted on request.
- Google Analytics: event-level data is kept for no more than 14 months.
- AppsFlyer: according to AppsFlyer’s retention policy.
- Support messages: as long as needed to handle your request and keep a record of it.
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.
- Turn tracking on or off in Settings > Privacy & Security > Tracking.
- Change the app’s permissions in the Settings app.
- Deleting SoundLab removes its data from your device. Files you saved in iCloud Drive stay there until you delete them.
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.
