Privacy Policy · Beat Maker Pro

CloudEx Inc. ("we", "us", or "our") operates the "Beat Maker Pro" app (the "Service"). This Privacy Policy explains what information we collect, how we use it, and the choices available to you. By using the Service, you are deemed to have agreed to the practices described in this Policy.

1. Our Core Principle

Beat Maker Pro is a music-making app: you tap beats on pads, enter melodies with steps or a piano roll, and chop sounds recorded with your microphone into songs. Making beats on the pads, step entry, the piano roll, the synths, the sampler, the song arrangement, and the mixer all run entirely on your device and work without an internet connection. The only sounds the app plays are sounds it synthesizes itself and sounds you record or import. It never downloads sound content. There is no account and no sign-up.

Your songs and your recordings are yours. They are stored on your device, and we never receive, listen to, or transmit them to our servers. Specifically, we do not have access to any of the following:

The songs you make (notes, patterns, song arrangement, instrument sounds, mixer settings, and so on)
The sounds you record with the microphone, the audio files you import, or anything else the microphone picks up
The files you export (WAV, MP3, per-track files, and MIDI files)

Your songs and sounds leave your device only when you share or save an exported file yourself (Section 2), or through Android backup (Section 3.2).

2. Microphone, Audio Files, and Export

Microphone: The microphone is used only while you record in the sampler. It stops when you stop recording or leave the sampler screen. When "Start when sound is heard" is on, the app simply waits until a sound is heard and starts recording from that moment. Your recordings are stored only on your device, and we never receive them.
Importing audio files: The app reads only the files you pick in your device's file picker.
Where your data is kept: Your songs, recorded sounds, and settings are stored in the app's own storage on your device.
Export: WAV, MP3, per-track files (stems), and MIDI files go only to the share target or save location you choose. We never receive them.

3. Information We Collect

3.1 Information Collected Automatically

Crash reports: Via Firebase Crashlytics. When the app crashes (and when an operation such as audio output, recording, or export fails), the app sends Google the device model, OS version, app version, the crash record (stack trace), and a per-installation identifier. This does not include your songs or your recordings. We do not use Firebase Analytics (usage analytics).
Purchase information: The one-time "Premium" purchase is processed by Google Play. The app receives only the purchase status (whether Premium has been bought), and we never receive any payment information such as credit card numbers.
List of our other apps: To show cards and a list introducing our other apps in the menu, the app downloads the list (https://adblockerpro-lists.pages.dev/sister/sister.json) and the images it refers to from static files we host on Cloudflare Pages. No information linked to you as an individual is sent. As with any request to a web server, the server receives general information such as your device's IP address as part of the connection. Tapping an app in the list opens its page on Google Play.

3.2 Information Stored Only on Your Device

Your songs: Notes, patterns, song arrangement, tracks, instrument sounds, mixer settings, and so on are stored in the app's storage on your device.
Recorded and imported sounds: Stored in the app's storage on your device, together with the slice points you set.
App settings: Settings such as the colour theme and the export format are stored on your device.
Android backup: If backup is turned on in your device settings, Android may include your songs and settings in the backup it saves to your own Google account (Google Drive). Recorded sounds are excluded from this cloud backup. When you transfer data directly to a new phone (device-to-device transfer), your recorded sounds are copied too. This is handled by Android; we have no access to it.
When you uninstall: Uninstalling the app or clearing its data deletes all the songs, recorded sounds, and settings in the app's storage. Files you have exported remain in the save location you chose.

3.3 Information We Explicitly Do Not Collect

Your songs, your recorded sounds, the audio files you import, or anything else the microphone picks up
The files you export
Your location (on Android 11 and earlier the app asks for the location permission to find Bluetooth devices, but it does not use or store your location)
Your name, email address, phone number, or contacts (the app has no account or sign-up)
Your advertising ID

3.4 Permissions the App Requests and Their Purposes

Beat Maker Pro uses the following permissions only for the stated purposes:

Microphone (RECORD_AUDIO) — Used only while you record in the sampler. The app asks for it when you try to start recording.
Nearby devices (BLUETOOTH_SCAN / BLUETOOTH_CONNECT, Android 12 and later) — Used only to find and connect to a Bluetooth MIDI keyboard (a Premium feature). The app asks for it when you search for Bluetooth MIDI on the MIDI keyboard screen. It is never used to determine your location.
Bluetooth (BLUETOOTH / BLUETOOTH_ADMIN, Android 11 and earlier) — As above, used only to find and connect to a Bluetooth MIDI keyboard.
Location (ACCESS_FINE_LOCATION, Android 11 and earlier only) — On Android 11 and earlier, the system requires this permission to search for Bluetooth devices. The app asks for it only when you search for a Bluetooth MIDI keyboard, and it does not use or store your location.
Internet (INTERNET) — Used only for sending crash reports, Google Play purchase verification, in-app reviews and in-app updates, downloading the list of our other apps, and showing this privacy policy in the app. Making music, recording, and exporting do not require an internet connection.

USB MIDI keyboards work without any permission.

4. How We Use Information

The limited information we collect is used only for the following purposes:

Operating and maintaining the Service
Verifying your Premium purchase
Diagnosing and fixing crashes
Responding to support inquiries
Complying with applicable laws

5. Third-Party Services

Beat Maker Pro uses the following third-party services. Each service has its own privacy policy.

Google Play Billing (Google LLC) — the one-time Premium purchase; payment is completed on Google Play, and the app receives only the purchase status
Firebase Crashlytics (Google LLC) — crash diagnostics
Google Play In-App Review and In-App Updates (Google LLC) — let you rate the app and install updates without leaving it; handled by Google Play
Cloudflare Pages (Cloudflare, Inc.) — hosts the list of our other apps and its images (static files)

Beat Maker Pro does not use your advertising ID and does not provide your data to advertising networks.

6. Data Retention

Crash reports: retained for 90 days, then deleted.
Support emails: retained for 12 months after the last reply, then deleted (except where legally required).
Your songs, recorded sounds, and settings on your device: kept until you delete them, uninstall the app, or clear the app's data. You can delete songs and recorded sounds in the app at any time.

7. International Data Transfers

We are based in Japan. The infrastructure used for crash diagnostics and for hosting the list of our other apps may be located in various countries. When you use the Service, the minimal information described above may be processed outside your country of residence under standard contractual safeguards.

8. Your Rights

Depending on where you reside (e.g., the EEA, UK, California, Japan), you may have the right to request access to, correction of, or deletion of the limited information we hold. You can:

Delete songs and recorded sounds in the app at any time, or uninstall the app or clear its data to erase all the songs, recorded sounds, and settings on your device
Withdraw the microphone, nearby devices, or location permission in your device settings at any time
Contact us at the address below to make a request regarding the information we hold

9. Children's Privacy

Beat Maker Pro is not directed to children under the age of 13 (or the equivalent minimum age in your region). The app has no account and is designed not to collect personal information. If we inadvertently collect information from such a child, we will delete it promptly upon being contacted.

10. Changes to This Policy

This Privacy Policy may be updated from time to time. The latest version is always published at this URL together with its effective date. We will also notify you within the app of significant changes as appropriate.
