RIVET

Privacy Policy

Updated 11 November 2026

The short version

RIVET has no accounts and no servers of its own, and the metronome itself collects nothing about you. The free version shows adverts from Google AdMob, and Google's advertising software collects some technical data in order to deliver them; exactly what is described under "Adverts" below. Your tempo, meters, riffs and drill choices never leave your device.

What RIVET stores

RIVET itself stores two on/off values: whether RIVET Pro is active, so a paying user is not shown an advert for the second it takes the App Store to confirm a purchase at launch, and, on iPad, whether you switched on the edge flash. They stay on your device and are removed when you delete the app.

Google's advertising components keep their own local settings on the device too, such as the state they need between launches and which region's advertising rules apply. Those are also removed when you delete the app.

Adverts

The free version of RIVET shows adverts supplied by Google AdMob. Every advert request RIVET makes is marked non-personalised, which means Google is told not to use any profile about you to choose what you see. Adverts are also limited to content suitable for all ages.

To deliver adverts, measure them and prevent fraud, Google's advertising software collects the following while the free version is running: device identifiers (the advertising identifier is not available to it, because RIVET never asks for tracking permission); your approximate location, derived from your IP address; advert interaction data, such as which adverts were shown and whether one was tapped; and diagnostic data, such as performance and crash information. Google may associate some of this data with your device. It is used for advertising, advert measurement, analytics and fraud prevention.

RIVET does not receive this data. Google processes it under its own privacy policy and the advertising terms RIVET operates under, which require Google to protect it. See policies.google.com/technologies/partner-sites and Google's data disclosure for this software at developers.google.com/admob/ios/privacy/data-disclosure.

RIVET does not ask for permission to track you across apps and websites, because it does not do that. RIVET Pro removes adverts entirely: the advertising software is not started at all for a Pro user.

If you are in Europe

RIVET does not show a consent prompt anywhere. In the EEA, the UK and Switzerland, Google therefore serves only "limited ads": they are not personalised, do not use device identifiers, and do not use cookies or local storage except to detect fraud. Google still uses your IP address to deliver them. See Google's description of limited ads.

Purchases

Purchases are handled entirely by Apple. RIVET never sees your payment details, your name, or your Apple Account. It asks Apple one question (is RIVET Pro active on this Apple Account?) and stores only the yes or no.

On Android

The Android version behaves the same way, with these differences. Purchases are handled entirely by Google Play: RIVET never sees your payment details, your name or your Google account, asks Google Play only whether RIVET Pro is active, and stores the yes or no. RIVET also stores your last practice settings (tempo, meter, accents, ramp, the loaded drill or riff) on the device, so the app opens where you left it; they are excluded from backups and deleted when you uninstall the app.

Adverts work exactly as described above: every request is non-personalised, content is limited to all ages, and no consent prompt is shown anywhere. RIVET removes the Android permission that would let the advertising software read your device's advertising ID. Google's advertising software still collects app and device information, approximate location from your IP address, advert interactions and diagnostics, as listed in Google's data disclosure for Android.

While the metronome is playing, Android shows a notification so the click can continue with the screen locked. It disappears when you stop and sends nothing anywhere.

Security

RIVET has no servers and sends nothing of its own over the network. What it stores stays in the app's private storage on your device, which other apps cannot read. Google's advertising and purchase software talks to Google only over encrypted (TLS) connections.

Retention, deletion and your choices

RIVET holds nothing about you to request, correct, export or delete: what it stores on your device is deleted with the app. Data collected by Google's advertising software is kept by Google according to its own retention policy at policies.google.com/technologies/retention.

To stop that collection, buy RIVET Pro or delete the app. To ask about data Google holds, use policies.google.com/privacy, or contact us below and we will help.

Children

RIVET is a general-audience app. It is not directed at children under 13 and does not knowingly collect personal information from them.

Changes

If what RIVET or its advertising partner collects changes, this policy is updated before the version of the app that does it is released, and the date at the top changes with it.
