Sonar privacy policy

Effective date: April 3, 2026

Sonar is a macOS app created by Michal Černý. This policy explains what data Sonar uses, where that data is stored, and how it is handled.

Data collection

Sonar does not collect personal data for the developer, does not run third-party analytics, and does not track users across apps or websites.

Data Sonar uses on your Mac

To work with App Store Connect analytics, Sonar may use the following information locally on your device:

Where data is stored

Sonar stores sensitive connection data locally on your Mac, including secure storage where appropriate such as Keychain-backed storage. Downloaded analytics files and caches are also stored locally on your device so the app can display reports and comparisons.

How data is shared

Sonar communicates directly with Apple services, including App Store Connect and Apple’s public App Store endpoints, to fetch the data needed for the app experience. The developer does not receive a copy of that data through Sonar.

Tracking and advertising

Sonar does not use advertising SDKs, does not profile users for advertising, and does not use tracking technologies for cross-app or cross-site behavior.

Your choices

You can stop using Sonar at any time, remove the stored App Store Connect connection from within the app, and delete the app from your Mac. Because Sonar is designed as a local desktop tool, there is no separate Sonar account to close.
