Visual Piano BarsPrivacy Policy

Lumicreative ("we," "us," or "our") provides Visual Piano Bars for Android, including its optional Pro upgrade. This policy explains how the app accesses, uses, stores, and shares information.

1. Sheet music, photos, and settings

The app accesses the sheet-music photos, cover images, and MusicXML files you choose, and photos you take with its camera features. It uses this content to recognize notation, read printed titles and tempo markings, create playable scores, and personalize your library.

Recognition and playback run on your device. We do not upload your photos, sheet music, recognized text, or generated scores to Lumicreative servers, and we do not use this content to train online AI models.

The app stores your library, source pages, cover artwork, edits, playback preferences, and appearance settings locally. You can select a picture storage location in Settings. On Android 10 and newer, captured scan pages are also copied to Pictures / Visual Piano Bars, where other apps with appropriate access and any photo backup services you enable may access them.

2. Permissions and file access

Camera access is used when you choose to scan music or take a cover photo. You can revoke camera permission in Android Settings. Android's file picker grants access to the images, files, or folder you select; the app may retain that access to work with your selected content. The app does not request microphone, contacts, or location permissions.

3. Google text recognition

The app uses Google ML Kit through Google Play services to read printed score titles and tempo markings. Google states that input images and recognized results are processed on the device and are not sent to its servers.

This component may contact Google for model downloads, updates, and compatibility information. Google also collects technical diagnostics and usage metrics, including device and app information, device or installation identifiers, processing performance, API configuration, input/output sizes, feature events, and error codes. Google uses these to operate, maintain, improve, and protect its services. Google states that ML Kit metrics are encrypted in transit.

See ML Kit Terms & Privacy, ML Kit data disclosures, and the Google Privacy Policy for details.

4. Pro purchases

Google Play processes purchases and restores for Visual Piano Bars Pro. The app receives purchase information, including a purchase token, product identifier, purchase status, and signed receipt, to verify, acknowledge, and restore your entitlement. It caches the signed receipt and verification information locally so Pro can remain available offline, and checks ownership with Google Play when available.

We do not receive your full payment card details through the app. Google handles payment and account information under its own policies. Clearing app data or uninstalling the app does not delete Google's transaction records or refund a purchase.

5. Advertising, sharing, and support

The app does not include advertising SDKs or a separate Lumicreative analytics or crash-reporting service. We do not sell your personal information or use it for targeted advertising. Google services process information as described above.

If you email us, we receive your email address, message, and any attachments you choose to send. We use this information to respond and resolve your request; our email provider processes it to deliver and store correspondence. Please send only the information needed for support. We may disclose support correspondence when legally required or necessary to protect rights and security.

6. Retention and deletion

• Saved scores: Delete a score from its library menu to remove its app-managed score, source pages, and cover copies. Files outside the app may remain if access is unavailable or deletion fails.
• All private app data: Use Android Settings to clear the app's storage, or uninstall it. This removes private library data, preferences, and cached purchase information. The app disables Android's standard automatic app backup.
• Pictures and original imports: Gallery copies, original imported files, and files in a folder you selected can remain after deleting a score, clearing app data, or uninstalling. Delete these separately with your gallery or file manager. Copies held by a backup provider are governed by that provider's controls and retention policy.
• Support messages: We keep correspondence as needed to resolve your request and maintain related support records, or meet legal obligations. You may request deletion by contacting us below.

We cannot remotely access or delete your on-device library. Google determines retention of information it processes under its policies; use Google's privacy and account controls for that information.

7. Security and your choices

The app uses Android's private app storage for its internal data. Files saved to shared storage have different access protections. Protect your device and review permissions and photo backup settings. No storage or transmission method can guarantee absolute security.

You can choose which files to import, manage camera permissions, change the picture location, and delete stored content. Depending on your location, applicable law may provide rights to access, correct, delete, or restrict use of personal information, or to complain to a data protection authority. Contact us to exercise rights concerning information we hold, such as support correspondence.

8. Children's privacy

The app does not ask users to provide their name, age, or contact details and does not offer public profiles or messaging. Its local music features follow the same practices regardless of age. Google services process technical and purchase information as described above. A parent or guardian who believes a child has sent personal information to us can contact us to request its deletion.

9. Policy updates and scope

We may update this policy as app features or data practices change. We will post the revised policy here and update the effective date, and provide additional notice or obtain consent when required. This policy covers the Android app; visiting a website or following an external link also involves that website's hosting and privacy practices.
