Pulsari Privacy Policy

Effective date: September 24, 2026

Pulsari is a metronome and practice app for Apple Watch, iPhone, and iPad, made by an independent developer. The short version: Pulsari has no accounts, collects no personal information, shows no ads, and does not track you. Your musical data stays on your devices and in your own iCloud. The details follow.

Data that stays on your device and in your iCloud

Your songs, setlists, practice history, routines, recordings, and settings are stored on your device. If you are signed in to iCloud, Pulsari syncs songs, setlists, and practice history between your devices using Apple’s CloudKit, stored in your private iCloud database. This data is protected by your Apple account and is not accessible to us — we cannot read, see, or share it. You can delete it at any time by deleting the app’s data in iOS Settings → Apple ID → iCloud, or by deleting the app.

Microphone and speech

With your permission, Pulsari uses the microphone for the tuner, timing accuracy scoring, practice recordings, and optional hands-free voice control. All audio is processed on your device. Audio is never uploaded or shared by the app. Practice recordings are saved only on your device and leave it only if you choose to share or export them yourself. Voice commands are recognized using Apple’s on-device speech recognition; what you say is not sent to us or to any server.

Health data (optional)

If you allow it, the Apple Watch app records practice sessions as workouts in Apple Health, and the app may read basic readiness information to adapt your daily practice plan. Health data never leaves Apple Health, is never transmitted to us or to any third party, and is never used for marketing or advertising.

Anonymous usage analytics

To understand which features are used and improve the app, Pulsari sends a small set of anonymous usage events to PostHog, our analytics provider (PostHog Inc., US cloud). Examples: “a session was started in the 120–159 BPM range,” “the tuner was opened,” “onboarding was completed.” Values are intentionally bucketed into ranges rather than exact numbers. These events are associated with a random identifier that is not linked to your name, email, contacts, location, or any account — Pulsari has no accounts. We do not collect your precise settings, your recordings, your song names, or anything you type or say. We do not use the advertising identifier (IDFA), and the app never shows an App Tracking Transparency prompt because it does not track you across apps or websites.

Crash reports

If the app crashes, a crash report is sent to Firebase Crashlytics (a Google service) so we can find and fix the bug. Crash reports contain technical information such as device model, OS version, the app version, and the state of the code at the time of the crash, associated with a random installation identifier. They do not contain your musical content or any personal information. We use Crashlytics only for crash reporting — Pulsari does not include Google’s advertising or ad-attribution components.

Band sync on your local network

Features that keep several devices in time (band sync, ensemble mode, sharing between nearby devices) communicate directly between devices over your local network or peer-to-peer connections, with your permission. Timing and setlist data exchanged this way goes only to the devices you connect to — not to us or to any server.

Purchases

Optional upgrades are one-time purchases made through Apple’s App Store. Payment is handled entirely by Apple — we never see your payment details. The app records only an anonymous event that a purchase occurred (for example, “Pro was purchased”), with no identity attached.

Children

Pulsari is not directed at children under 13, does not knowingly collect personal information from anyone, and contains no third-party advertising.

Your rights and choices

  • You can deny or revoke microphone, speech, Health, and local-network permissions at any time in iOS Settings; the related features simply turn off.
  • Because analytics and crash data are anonymous, we cannot look up data belonging to a specific person. If you have a privacy question or request (including under GDPR or CCPA), contact us through our support page and we will help.
  • Deleting the app removes all locally stored data. iCloud-synced data can be removed in iOS Settings → Apple ID → iCloud → Manage Storage.

Changes to this policy

If we change what the app collects, we will update this page and the effective date above before the change ships.
