Sound Game — Privacy Policy

Last updated: 30 May 2026

Sound Game is an iPhone and iPad game developed by Leo Baron. Solo play is fully offline. The optional multiplayer feature ("challenge a friend") sends a small amount of game data to the app's own server so two players can compare scores. This policy explains exactly what is collected, when, and why.

Solo play collects nothing

If you only play solo, Sound Game collects, transmits, and logs nothing. There are no accounts, no analytics, no advertising SDKs, no telemetry, no crash reporters, and no network calls. Your high scores stay on your device.

Multiplayer & challenges

Data is sent to our server only when you actively create or accept a challenge. At that point the app sends:

• A display name you choose (a nickname — it does not need to be your real name), shown to the friends you duel.
• A random device identifier generated on first use. It is a random UUID, not linked to your Apple ID, phone number, email, or any advertising identifier.
• Game results — the tone frequencies of the challenge and your guesses, used by the server to compute and compare scores fairly.
• A push notification token — only if you enable notifications — so we can tell you when a friend takes or beats your challenge.

We do not collect your name, email, contacts, location, device sensors, or any advertising identifier. We do not sell or share this data, and there is no advertising or third-party analytics.

Where it is processed

Multiplayer data is processed and stored on infrastructure operated by Cloudflare, Inc. on the developer's behalf, solely to run the challenge feature. No other third party receives your data. Push notifications, when enabled, are delivered through Apple's Push Notification service.

Data stored on your device

The app stores the following only on your device:

• Your personal high scores, per difficulty and game mode (UserDefaults).
• Your chosen display name (UserDefaults) and the random device identifier (iOS Keychain).
• Whether you have dismissed the first-run onboarding screen.

Audio

Sound Game generates tones using the iOS AVAudioEngine framework. It does not request, access, or record microphone input. No ambient audio from your environment is ever captured.

Children

Sound Game is rated 4+. Multiplayer collects only a self-chosen nickname and a random identifier, never real-world personal information. We recommend not using a real name as the display name.

Your rights & data deletion

Because multiplayer data is tied to a random identifier rather than an account, the easiest way to stop all collection is to play solo or disable notifications. To request deletion of challenge data associated with your device, email leovbaron@me.com and we will remove it. Rights granted by the GDPR (EU/EEA/UK), CCPA (California), LGPD (Brazil), PIPEDA (Canada), and PDPA (Singapore) — access, correction, deletion, portability — are honored through this contact.

Changes to this policy

If the data practices change, this page and the "Last updated" date will be revised, with a release-note callout in the affected app version.
