Privacy Policy
Huabai FM ("us", "we", or "our") operates the Huabai FM mobile application (the "Service"). Package name on Google Play: com.jng.fm. Store listing titles may vary by language or locale.
This page explains how we access, collect, use, retain, and delete information when you use the Service. By using the Service, you agree to this Privacy Policy.
What the Service does
Huabai FM is an ambient / white-noise sound app. You can play and mix nature and lifestyle sounds, adjust settings (such as sound effects and haptic feedback), organize tags, and unlock additional sounds and features with an optional Google Play subscription (VIP).
Definitions
Service — the Huabai FM mobile application.
Personal Data — information relating to an identified or identifiable individual.
Usage Data — technical information collected automatically when you use the Service (for example device type, OS version, diagnostic events).
Types of Data Accessed and Collected
App permissions (current Google Play build)
The current Google Play build declares:
- Internet — to load sound assets and complete Google Play Billing flows
- Vibrate — for optional haptic feedback you enable in settings
The Service does not require account registration with us to use core playback features. It does not request contacts, SMS, microphone, precise location, or photo library access for core sound playback in the current build.
Settings and local app data
Preferences and in-app state (for example language, sound-effect / haptic toggles, sound order, tags, and related focus/tag data) are stored on your device.
Sound content delivery
To play sounds, the Service may download or stream audio files from our content hosting (object storage). Requests for those files may include ordinary network metadata (such as IP address and user-agent) processed by the hosting provider to deliver the file. Sound content itself is not personal diary content.
Purchases / VIP
Optional VIP / membership is billed through Google Play Billing. We do not collect or store your payment card details. Google processes the purchase under Google’s policies. We receive purchase / entitlement status needed to unlock features you paid for.
Support communications
If you email us for feedback or support, we receive the address and content you send so we can reply.
Advertising and analytics SDKs
The current Google Play build is configured with ads disabled (adClose = true). Shared libraries may still include advertising or analytics SDK components. If those components process device identifiers or diagnostic Usage Data, their use is limited to what the build enables and to operating or securing the Service. If advertising is turned on in a future release, we will update this policy before that change.
Use of Data
- To provide sound playback, mixing, and in-app settings
- To deliver sound assets over the network
- To process VIP entitlements via Google Play
- To provide customer support when you contact us
- To maintain, secure, and improve the Service
Data Retention
- Local app data: Kept on your device until you clear app storage, delete in-app items (such as tags), or uninstall the app.
- Purchase records: Held by Google Play under Google’s retention practices; we keep only the entitlement state needed to unlock features on the device.
- Support emails: Kept as long as reasonably needed to handle your request, then deleted or anonymized when no longer required.
- No account cloud diary: We do not operate a user-account cloud database that stores your local preferences or tags for the core features described above.
Data Deletion
- In the app: Delete tags or related local items using the in-app controls where available.
- On device: Clear the app’s storage in Android settings, or uninstall Huabai FM to remove app-local data on that device.
- Subscriptions: Manage or cancel Google Play subscriptions in Google Play subscription settings. Uninstalling the app does not automatically cancel a subscription.
- Deletion request to us: Email jiniangu2024@gmail.com with subject “Data deletion request”. Because core preferences are stored on your device and not in a user account on our servers, we typically cannot remotely erase on-device data; we will confirm that, guide you to on-device deletion, and delete related support correspondence we hold. We aim to respond within 30 days.
Children’s Privacy
The Service is not directed to children under 13 (or the minimum age required in your country). We do not knowingly collect Personal Data from children. If you believe a child has provided us information via support email, contact us and we will delete it.
Security
No method of electronic storage or transmission is 100% secure. We use commercially reasonable measures appropriate to a local-preferences + content-delivery app.
International users
If you contact us by email, your message may be processed where we operate support (which may differ from your country). Sound asset requests are served by content hosting infrastructure that may be outside your country.
Changes
We may update this Privacy Policy by posting a new version on this page. Changes are effective when posted.
