Service description

BandMATRIX lets you manage sheet music, tablature and repertoires, import and sync files from Google Drive, connect devices directly over Bluetooth and Wi-Fi, and control compatible MIDI equipment. Available features depend on the version and device compatibility.

Conditions of use

You must use the application lawfully, respect third-party rights and grant the permissions required by the features you choose to use.

Free and Premium versions

BandMATRIX offers a free version and Premium features through a one-time Google Play purchase, with no subscription or recurring renewals. The features and price are displayed before purchase. The price includes applicable taxes under EU rules. Access is subject to purchase verification and Google Play terms. You receive a license to use the software. Ownership is retained by the developer. Once payment is complete, the Pro features remain unlocked under the conditions described.

Purchases and refunds

Google Play processes purchases. The price and applicable taxes are displayed before you confirm payment. Under European consumer rules on digital content supplied electronically, when you download and immediately unlock Pro features, you expressly consent to performance starting and acknowledge the loss of the right of withdrawal, subject to Google Play refund policies.

Google Drive and external services

Importing and syncing from Google Drive requires the relevant authorization or file selection. You retain control of your original documents. External services are subject to their providers’ availability and terms.

Communication between devices

Sheet music syncs directly over Bluetooth and Wi-Fi without a developer-operated server. Only authorize connections to trusted devices and share content for which you hold sufficient rights.

MIDI equipment

Operation depends on equipment compatibility, configuration and connections. Check your setup before rehearsals or performances and follow the manufacturers’ instructions.

Intellectual property

BandMATRIX grants no right to reproduce or distribute third-party musical works without authorization. It is a tool for managing and viewing documents and sheet music in PDF or image format. Users are solely responsible for the files, sheet music, tablature and content they import, store or reproduce in the app and must ensure they have the necessary rights or licenses. The developer is not responsible for users’ misuse of copyrighted material.

Availability and updates

The developer may release security updates, fixes and improvements. Changes will respect acquired rights and legally required guarantees.

Liability

The developer will make efforts to keep the application working correctly but cannot guarantee that it will be free of errors or interruptions. Keep backups. These terms do not exclude liability that cannot legally be excluded or limit rights that cannot be waived.

Privacy

See the Privacy Policy for information about data processing.

Changes

These terms may be updated to reflect legal, technical or functional changes. Users will be informed of material changes and consent will be requested where required.

Applicable law
