Metronome — Privacy Policy

Effective date: 2026-09-12 Last updated: 2026-09-12

Summary

Metronome keeps time and remembers the songs you practise. Everything it remembers stays on your phone.

There is no account, no sign-up, no cloud and no server of ours anywhere. Your setlists are not uploaded, not analysed and not used to train anything. We cannot see them and we could not hand them to anyone if we were asked, because we never receive them.

The app does not use the microphone. It makes sound; it does not listen. There is no recording of any kind, and no microphone permission in the app for one to hide behind.

The only data that leaves your device is what Google AdMob needs to show ads.

Who we are

• App name: Metronome
• Developer: Dash Fusion
• Support email: dash.fusion@outlook.com
• App listing: Google Play (com.dashfusion.listmetronome)

What the app stores, and where

Everything below is written to this app’s private storage — a local database and a preferences file that no other app on your phone can read:

• Setlists: the name you gave each one, and when you last edited it
• Songs: the name, the tempo in beats per minute, the time signature, which beats you accented, how many bars to run for, and their order in the setlist
• App preferences: theme, whether to keep the screen on while playing, whether to use the wallpaper’s colours, when a rewarded ad-free window runs out, and a count of finished practice sessions used to decide how often an ad may appear

We hold no copy of any of it. There is no analytics SDK in this app, no crash reporter of our own, and no telemetry. None of it is used for advertising.

The app opts out of Android cloud backup and device-to-device transfer (allowBackup="false"), so your setlists are not copied into Google’s backup service either.

Consequence, stated honestly: because your setlists exist only on this phone, uninstalling the app deletes them permanently and we cannot restore them. Settings → Save a copy writes a JSON file wherever you choose, and that copy is yours to keep.

Saving a copy is something you do, not something we do

Save a copy and Restore a copy use Android’s own file picker. You choose where the file goes and where it comes from, the file moves directly between your phone and that location, and it does not pass through us. We never see it.

Third-party services we use

Google AdMob (ads)

The app is supported by ads served by Google AdMob. Ads are the only reason the app needs an internet connection at all; the metronome, the setlists and the backup all work with no connection whatsoever.

The app shows no banner ads, and never shows an ad while the metronome is running. What it shows is an occasional full-screen ad after a practice session has ended — and only a session that actually ran, not a quick tempo check — plus an optional rewarded ad you can choose to watch to switch ads off for 24 hours. Nothing in the app is locked behind either one.

To serve ads, Google receives data from your device, which may include your device’s advertising identifier (AD_ID), coarse location inferred from your IP address, device and app information, and ad-interaction data. It does not receive your setlists, your songs, your tempos or your preferences — the app never sends those anywhere. Google’s processing is done as an independent controller under its own policies:

• Google Privacy Policy: https://policies.google.com/privacy
• How Google uses information from partner sites and apps: https://policies.google.com/technologies/partner-sites

Consent (UMP)

Where required by law, the app shows Google’s User Messaging Platform consent form before ads are initialised, and records your choice. In the EEA and the UK you are asked about personalised advertising; in covered US states you are offered the opt-out required there. You can change your decision at any time from Settings → Ad privacy options, and if you decline, every metronome and setlist feature continues to work exactly as before.

Data we collect ourselves

None. We operate no servers, no accounts and no analytics. We have no database with your name in it and no way to identify you or your device. We do not sell or share personal information, because we do not have any.

Permissions the app requests

The whole list, and it is short:

• Internet / network state (INTERNET, ACCESS_NETWORK_STATE) — solely so the Google Mobile Ads SDK can fetch ads. Turn off Wi-Fi and mobile data and no ads load; every other feature still works.
• Advertising ID (AD_ID) — required by Google Play for apps that serve ads; used by AdMob as described above.

That is all three of them. The app requests no microphone, no storage permission of any kind, no notifications, no camera, no contacts and no location. It cannot read your other files.

Children

This app is not directed at children and is intended for users aged 13 and over. We do not knowingly collect personal information from children — as described above, we hold no personal data at all.

Your choices

• Ad personalisation: change your consent decision any time via Settings → Ad privacy options.
• Reset your advertising ID or opt out of personalised ads in Android’s own settings, under Settings → Google → Ads.
• Delete your data by deleting setlists in the app, or by clearing the app’s storage or uninstalling it. Because everything lives only on your device, that removes it completely and irreversibly — there is no copy anywhere else, and no deletion request to send us.

Changes to this policy

If we change this policy we will update the Last updated date above and publish the new version at this URL. Material changes will also be noted in the app’s release notes on Google Play. This policy is versioned publicly in the Dash Fusion privacy repository, so any change is visible in its history.
