Privacy Policy — Piano: Learn & Play Music

1. At a glance

2. Who we are and what this covers

This Privacy Policy explains how Mobile Clean System Lab processes personal data when you use Piano: Learn & Play Music (piano.learn.music.tutor), which helps you learn and practise piano with guided lessons and playable keys.

Product list and related notices: https://fmappstudio.uk/legal/. Related terms: Terms of Use.

3. Contact details

We have not appointed a separate EU/UK GDPR Article 27 representative. Privacy requests should be sent to the email above.

4. What data we collect

5. Why we process it, on what legal basis, and for how long

6. Sensitive permissions this app requests

Permissions are requested in context. You can revoke them in iOS Settings or Android settings; some features will stop working. Platform-specific permissions below apply only where that platform requests them.

This app does not request the sensitive device permissions listed in our special-permission catalogue. Standard storage, photo library, or notification prompts may still appear for ordinary features on iOS or Android.

7. Who receives data

If a build ships fewer SDKs, only the shipped services apply. Store data disclosures (Google Play Data safety / Apple privacy labels) should match this list for each product.

8. Advertising and your choices

• Android: reset or delete your Advertising ID in device settings.
• iOS: limit ad tracking / App Tracking Transparency prompts in Settings, and reset advertising identifier where available.
• Use in-app Privacy options where shown (UMP / privacy form).
• Opt out of interest-based ads via device settings or partner tools.

Limits we accept: We do not use SMS content, consumer health cycle data, or Accessibility screen content for advertising.

9. Consent in the EEA, the UK and Switzerland

Where required, we use a Google-certified consent management platform integrated with the IAB Transparency and Consent Framework. Personalised advertising and related analytics storage rely on consent, not legitimate interest, for those regions.

Consent signals such as ad_storage, analytics_storage, ad_user_data and ad_personalization are passed to Google as required. You can reopen the privacy options form from app settings where available.

10. International transfers

Our studio is based in Hong Kong. Google and other processors may process data in the United States and other countries. Where GDPR requires safeguards, we rely on the processors’ Standard Contractual Clauses and other lawful transfer mechanisms. You may request more information by emailing us.

11. How long we keep data

• On-device content: until you delete it or uninstall the app.
• Support emails: up to 3 years after the request is closed.
• Analytics/crash: see the table in section 5.
• Legal claims and accounting: up to 10 years where needed.

12. Security

Data the app sends from the device leaves over TLS. No method of transmission or storage is perfectly secure. Keep your device updated and protect access to your phone.

13. Children

Our apps are directed to a general audience and are not intended for children under 13 (or a higher age required in your country). We do not knowingly collect personal data from children. Contact us for deletion if you believe a child has provided data.

14. Your rights

Depending on where you live, you may have rights to access, correct, delete, restrict, object, port data, withdraw consent, and complain to a supervisory authority. Email mobilecleansystemlab@gmail.com. We respond within 30 days where required, or the period your law sets. For deletion steps see Data deletion.

15. Automated decision-making

We do not use automated decision-making that produces legal or similarly significant effects about you.

16. Notice to California residents

Categories collected match section 4. We may “share” personal information for cross-context behavioural advertising via ad partners even when we do not sell data for money. You may opt out by Advertising ID / IDFA controls, in-app privacy options, Global Privacy Control signals where technically received, or by emailing us with the subject “Do Not Sell or Share”.

We do not sell personal information of consumers under 16. Sensitive personal information is used only to provide the app features you request.

17. Notice to residents of other US states

Residents of states such as Colorado, Virginia, Connecticut and others may have similar access, deletion and opt-out rights, and in some states an appeal process. Email us to exercise these rights. Health apps should also review Consumer Health Data Privacy.

18. Country-specific information

Brazil, Canada, Japan, Korea, India, Australia and other countries may grant additional rights or require local notices. Contact us to exercise applicable rights. India’s child threshold is 18; we do not target children.

19. Changes to this notice

• Version 2026.10.09 (9 October 2026): republished under Mobile Clean System Lab with Hong Kong contact details and per-app structure aligned to our legal standard.

Material reductions of your rights will be announced in-app or on this page with reasonable notice.
