Privacy Policy

Effective 2026-11-07Version 1.0Operator Vicino Labs

Pianino, a piano, metronome and tuner app made by Vicino Labs, does not collect personal data. There is no account, no ad network, no purchase and no server. The microphone sound the tuner uses only serves to measure pitch on your device; it is never recorded or sent anywhere. Here are the details, as precisely as we can put them.

1. Data controller

The operator's address and contact details are at the end of this document and in the Impressum.

Vicino Labs is the “controller” under the EU General Data Protection Regulation (GDPR) for any personal data processed in connection with this app.

2. Summary

  • No account or sign-in. Your settings are stored only on your device — we cannot see them.
  • The microphone is used only while listening is on in the tuner. The sound is analysed on the device in real time for its pitch and then discarded — it is never recorded, stored or sent.
  • No ad networks and no in-app purchases. The only ad in the app is our own banner for welegato, a service of the same company. No advertising ID, and no analytics or tracking tools.
  • The app does not connect to the internet by itself. Your browser or app store opens only when you tap the welegato banner, “More apps for musicians” or a link to our legal documents.

3. Data stored on your device

  • Piano settings — piano sound, concert pitch (A4), number of keys and rows, key labels, visible range
  • Metronome settings — tempo, metre, click sound, accents, subdivision
  • Tuner settings — transposing instrument
  • Display settings — language, note-name system, appearance, colour theme

This data stays in the app's private storage on your device and is never sent to us. It is deleted when you uninstall the app. Legal basis: providing the app's features (Art. 6(1)(b) GDPR).

4. Microphone (tuner)

The first time you turn on listening in the tuner, the app asks for your device's microphone permission.

  • The microphone sound is used only to calculate the pitch (frequency) in the device's memory, a fraction of a second at a time, and is overwritten straight away. The pitch graph on screen keeps only the pitch values of the last few seconds and is cleared when you leave the tuner.
  • The sound itself is never recorded to a file, stored or sent anywhere. The app does not have the internet permission.
  • The microphone is switched off when you leave the tuner or the app goes to the background.
  • You can revoke the permission in your device settings at any time. Only the tuner's listening stops working; the piano, the metronome and the reference tones still work.

5. Sound, background playback and screen

Piano sounds and metronome clicks are generated on the device from sound samples included in the app. The metronome can keep playing when you switch apps or turn off the screen (iOS background audio), and the screen stays on while the tuner is listening. All of this works entirely on the device and sends no data.

6. The welegato banner and external links

At the bottom of the screen there is a banner for welegato, a music-lesson platform run by the same company (Vicino Labs), and the settings show “More apps for musicians” from the same company. Your browser or app store opens only when you tap one of them; the app does not pass on any personal data, before or after.

  • The link carries a campaign tag (utm_source=pianino) that only says the visit came from Pianino. It contains no value that identifies you.
  • Once a website or store page is open, its own privacy policy applies — welegato privacy policy; for this site (vicinolabs.com) see Datenschutz.
  • As with any website visit, your device's IP address reaches that site's server (hosting provider) when the page loads.

7. App stores

The app is distributed through Google Play and the Apple App Store. Installs, updates and crash reports are handled by the store under its own privacy policy; we only see anonymous statistics the store provides (such as install and crash counts).

8. Data we don't collect

We do not collect names, email addresses, phone numbers, location, contacts, photos, camera data, recorded sound, advertising IDs or device identifiers. The Android app does not even have the internet permission.

9. Children

Because the app collects no personal data, there is no age restriction for privacy reasons.

10. Your rights

  • Access, rectification, erasure, restriction of processing, data portability and objection (Art. 15–21 GDPR)
  • Lodge a complaint with a supervisory authority — e.g. the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia (LDI NRW) or the authority where you live

We hold no data about you; the settings on your device are deleted when you uninstall the app. For any question, please contact us below.

11. Changes to this policy

We may update this policy when the law or the app changes; changes and the effective date are posted on this page.
