1. Introduction
Steven Huang ("we," "us," or "our") operates the Simple Piano mobile application (the "App"), available on iOS and Android platforms (Bundle ID: com.hsiangyu.simplepiano). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App.
By downloading, installing, or using the App, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree with the terms of this Privacy Policy, please do not use the App.
2. Information We Collect
2.1 Information Collected Automatically
When you use the App, certain information may be collected automatically by third-party services integrated into the App:
- Advertising Identifiers: Your device's advertising identifier (e.g., Google Advertising ID on Android, IDFA on iOS) may be collected by our advertising partner to serve ads. On iOS 14.5+, ad tracking requires your explicit permission through Apple's App Tracking Transparency framework; without your permission, only non-personalized ads are served.
- Device Information: Device model, operating system version, language settings, and general device configuration may be collected by advertising services to deliver appropriate ads.
- Ad Interaction Data: Information about your interactions with advertisements displayed in the App, such as ad views and clicks.
- IP Address: Your IP address may be collected by Google AdMob for the purpose of delivering ads.
2.2 Information Stored Locally
The App stores certain data locally on your device to provide its core functionality:
- App Preferences: Your settings (e.g., keyboard size) and ad frequency data (e.g., last ad display time) are stored on your device using local storage.
- Recording Data: Your piano recordings, including recording name, note sequences, and duration, are stored in a local database on your device. These are MIDI note events, not actual audio recordings.
This locally stored data does not leave your device and is not transmitted to us or any third party.
2.3 Information We Do NOT Collect
We do not collect any personally identifiable information (PII) directly. Specifically, we do not collect:
- Names, email addresses, or phone numbers
- Location data
- Camera, microphone, contacts, or other sensitive device features
- Crash reports or analytics data
3. How We Use Your Information
We use the information associated with our App to:
- Provide Core Functionality: Store your piano recordings and preferences locally on your device.
- Display Advertisements: Serve ads through Google AdMob to support the free availability of the App.
We do not use any data to personally identify you, build user profiles, or track you across other apps or websites.
4. Third-Party Services
Our App uses the following third-party services that may collect information:
4.1 Google AdMob
We use Google AdMob to display interstitial advertisements in the App. AdMob may collect and use certain data to serve ads, including:
- Device advertising identifiers (Android Advertising ID; IDFA on iOS only with your explicit consent)
- Device information (model, OS version)
- IP address (for general location-based ad targeting)
- Ad interaction data
On iOS 14.5+, personalized ads require your explicit consent through Apple's App Tracking Transparency (ATT) prompt. If you do not grant consent, only non-personalized ads will be shown. On Android, you can opt out of personalized advertising by adjusting your device settings:
- Android: Settings > Google > Ads > Opt out of Ads Personalization

6. Data Storage and Security
- Local Data: Your recording data and app preferences are stored locally on your device. This data is only accessible through the App and is removed when you uninstall the App.
- Advertising Data: Data collected by Google AdMob is stored and processed by Google in accordance with their privacy policy.
We implement reasonable measures to protect the information associated with our App. However, no method of electronic storage or transmission is 100% secure, and we cannot guarantee absolute security.
7. Data Retention
- Local Data: Recording data and preferences are retained on your device until you clear the App's data or uninstall the App.

8. Children's Privacy
Our App is not specifically directed at children under the age of 13. We do not knowingly collect personal information from children under 13. The App does display advertisements served by Google AdMob, which operates under its own policies regarding children's data.
