Privacy Policy

Effective 2026-10-01Version 3.0Operator Vicino Labs

Appoggio, a breathing-training app for singers made by Vicino Labs, does not collect personal data. There is no account, no ad network, no purchase and no server, and your training history never leaves your device. 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. Training settings, reminder times and training history are stored only on your device — we cannot see them.
  • No ad networks (such as AdMob) and no in-app purchases (since version 1.2.0). 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 SDKs (e.g. Firebase Analytics).
  • The app does not connect to the internet by itself. Your browser opens only when you tap the welegato banner or a link to our privacy policy or terms.
  • Reminders are local notifications scheduled on your device — no push server is involved.

3. Data stored on your device

  • Training settings — number of rounds, timer style, feedback (sound/vibration), language, dark mode, colour theme
  • Reminder settings — on/off and time
  • Training history — the dates you trained and which of the four methods you completed that day. We don't store the exact time or session length.

This data stays in the app's private storage on your device and is never sent to us. You can delete it anytime with “Reset records” on the records screen or by uninstalling the app. Legal basis: providing the app's features (Art. 6(1)(b) GDPR).

4. Notifications, sound, vibration and screen

When you turn on a reminder, the app asks for your device's notification permission. Notifications are scheduled and shown on the device without contacting any server, and you can revoke the permission in your device settings at any time. The sound and vibration cues between breathing phases, and keeping the screen on during a session, also work entirely on the device and send no data.

5. The welegato banner and external links

At the bottom of the home and training screens there is a banner for welegato, a music-lesson platform run by the same company (Vicino Labs). The welegato website opens in your browser only when you tap the banner; the app does not pass on any personal data, before or after.

  • The link carries a campaign tag (utm_source=appoggio) that only says the visit came from the app. It contains no value that identifies you.
  • Once a website is open, that website's 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.

6. App stores

The app is distributed through Google Play (and later possibly 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).

7. Data we don't collect

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

8. Children

Because the app collects no personal data, there is no age restriction for privacy reasons. Please practise breathing exercises sensibly and, for children, under adult supervision (see the health notes in our Terms).

9. 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; what is on your device you can delete yourself in the app (Reset records) or by uninstalling it. For any question, please contact us below.

10. 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. Unlike version 2.0, version 3.0 reflects app version 1.2.0, which no longer uses an ad network or in-app purchases.
