App Store Connect analytics without the mess.

In the macOS Keychain on your Mac, together with the issuer ID and key ID. Sonar uses the private key locally to sign short-lived tokens for Apple’s API. The private key itself is never sent anywhere, not even to Apple, and there is no Sonar server.

Apple only allows Admin keys to create Analytics Report requests. Finance and Sales and Reports keys can only download reports that already exist. Sonar creates the requests the first time you connect. You can revoke the key at any time in App Store Connect → Users and Access → Integrations.

Not to me or anyone else besides Apple. Sonar downloads the reports directly from Apple and keeps them in the app’s container on your Mac. I never receive a copy, and they are not part of usage statistics or crash reports.

No ads and no tracking across apps or websites. Sonar includes Google Firebase Analytics and Crashlytics, but both are off until you allow them: Sonar asks once after setup (in Demo Mode it doesn’t ask and both stay off), and you can change your choice anytime in Settings → General → Privacy (Share usage statistics, Send crash reports).

If you allow them, they are tied only to a random install ID. Usage statistics never include App Store Connect data, API keys, key file names or app IDs. Crash reports contain the crash or error and where in the app it happened, your Mac model, the macOS and app version and the device state at that moment.

Besides Apple and these opt-in reports, Sonar talks to RevenueCat to check whether you have Sonar Pro. RevenueCat gets a random customer ID and your App Store purchase data, never your App Store Connect data. Version 1.0.0 collected usage statistics without asking; 1.0.1 fixed that.

Yes. Choose Try Demo Mode on the first screen to explore Sonar with sample data.

Settings → Connection → Remove Connection deletes the key and token from the Keychain. Downloaded reports stay in Sonar’s folder ~/Library/Containers/com.michalcerny.sonar until you quit Sonar and delete that folder. Remove the connection before you delete the app: deleting the app may leave the Keychain items and that folder on your Mac.

Usage statistics and crash reports are deleted when their retention period ends (see the privacy policy). For purchase records, email me.

Sonar shows Apple’s Analytics Reports. Sales reports count units differently and usually come out higher, and in some metrics Apple only includes users who share analytics with developers. Fresh data arrives once a day, and the first reports take 1-2 days.
