Privacy Policy — Mintronome

Effective 2 November 2026

The app has no accounts and no server of its own. Your practice history is stored locally; your operating system may include it in device backups or device transfers.

What is stored on your device

Your current tempo, meter, subdivision, swing, gap-training and count-in settings, your sound and playback choices, and the beat animation you chose
Practice sessions: when they started, how long they lasted, the rhythm used most and the tempo range
While a practice is running, a copy of it so the time is not lost if the system closes the app; it is removed when you finish
Whether you bought "Remove ads", the date the app was first opened and when a full-screen ad was last shown, to keep ads within the limits above

The journal's charts and the quick-pick tempos are calculated on the device from these sessions. Deleting a session in the journal removes it from the device.

Uninstalling the app removes its local copy of this data. Operating-system backups may retain or restore it; manage those copies through your device or backup provider's settings. The app has no export or app-managed cloud sync, and it does not hand any of this data to the advertising SDK.

Advertising and automatically processed information

To cover running costs, the app shows Google AdMob ads in two places: a small banner on the practice history screen and, at most once a day, a full-screen ad after you finish a practice of ten minutes or more with "Finish & save" (never in the first week after installing). No ads are requested or shown while you practice. According to Google's own disclosure, the Google Mobile Ads SDK may automatically collect and share the following for advertising, analytics and fraud prevention:

IP address, and the approximate location inferred from it
Interactions such as app launches, taps and ad views
Diagnostics and performance data relating to the app and the SDK
Device or account identifiers such as the advertising ID (Android) or, where available, the advertising identifier (iOS)

Information processed by Google is subject to Google's privacy policy and advertising policies. Data in transit is encrypted with TLS.

The "Remove ads" purchase

The app offers "Remove ads" as a one-time, non-consumable purchase through the App Store or Google Play. The payment sheet and payment details are handled by Apple or Google directly; the app has no access to them. The app only asks the store whether the purchase is owned and keeps that answer on the device, so ads stay off offline. Receipts, order IDs, prices and account details are never stored by the app or sent to any server of ours. After the purchase no further ads are requested, and from the next launch the app does not start the advertising SDK or the consent flow.

Privacy choices

The app uses Google's User Messaging Platform (UMP). Where consent is legally required, a privacy choice screen is shown before any ad is requested. Where the choice can be revisited, the history screen shows "Privacy choices". The app does not ask for App Tracking Transparency permission on iOS. Your advertising ID and personalised-ads preference can also be managed in your device's privacy settings.

Children

The app is not designed for children under 13.

Changes

If this policy changes, the effective date above is updated and the new version is published at this address.
