Privacy policy

Last updated: 5 September 2026

Backing Band is a practice companion for musicians. We run no server for this app, there is no account or login, and the app contains no analytics, no advertising and no third-party SDKs. The app makes no connection to the internet and uses no external services, including iCloud; the sound is generated on the device. We receive no data from you.

1. Data controller

We have not appointed a data protection officer or an EU representative because we do not reach the relevant thresholds. Please address all requests to the contact above.

2. What data we process

What we explicitly do not collect

• No account, no name, no e-mail address
• No advertising, no advertising ID, no analytics, no trackers, no third-party SDKs
• No server, no iCloud sync and no network connection: your chord progressions never go to us or third parties

3. Permissions on your device

The app does not request any special system permissions.

4. Legal bases

We process personal data under the Swiss Federal Act on Data Protection (revFADP). Where the GDPR applies, we rely on:

• Performance of a contract (Art. 6(1)(b) GDPR) — everything needed for the app to deliver the function you requested.
• Legitimate interests (Art. 6(1)(f) GDPR) — secure and stable operation, abuse prevention, troubleshooting.
• Consent (Art. 6(1)(a) GDPR) — this app requests no special system permissions, so no separate consent is required.
• Legal obligation (Art. 6(1)(c) GDPR) — in particular commercial and tax retention duties for payments.

Sounds (included in the app, nothing is downloaded): Piano: Salamander Grand Piano V3 by Alexander Holm, licensed under CC BY 3.0. Drums: MuldjordKit by Lars Muldjord (FreePats version), licensed under CC BY 4.0. These samples were modified (shortened, faded, level-matched, pitch-corrected and converted to SoundFont); the licensors do not endorse this app. Public-domain sounds (CC0): FreePats project, Karoryfer Samples, D. Smolken, Versilian Community Sample Library. More sounds: GeneralUser GS by S. Christian Collins, used under its licence. The example chord progressions are general chord patterns or public-domain pieces (title, chord symbols and bar structure only; no melody, no lyrics).

6. Retention and deletion

We store nothing because we run no server for this app. Your chord progressions, setlists and settings live on the device only. Removing the app deletes this data.

Step-by-step instructions are available at Delete data.

7. Children and young people

This app is not directed at children. We do not knowingly collect personal data from children under 16. If we learn that such data has been submitted without parental consent, we delete it without delay.

8. Data security

Wherever the app transmits data at all, connections are encrypted via HTTPS/TLS. On the server side we use access restrictions, tenant separation and regular backups. Nobody can, however, guarantee absolute security for data transmission over the internet.

9. Your rights

• Access to the personal data we process
• Rectification of inaccurate data
• Erasure or destruction of your data
• Restriction of and objection to processing
• Receiving or porting your data in a common format
• Withdrawal of consent with effect for the future

An informal message to info@babala.ch or a call to 076 792 63 50. We normally respond within 30 days. To verify your identity we may request suitable proof. You may also lodge a complaint with a supervisory authority (Switzerland: FDPIC; EU: your competent authority).

10. Changes to this policy

We may adapt this policy when the app or the legal framework changes. The version published on this page, with the date shown above, is the applicable one. We announce material changes inside the app.
