Waveful is a frequency sound app designed to support rest, focus, meditation, breathing, and sound personalization. This Privacy Policy explains how Waveful handles information when you use the app.

1. Data Collection

Waveful does not collect personal data.

We do not collect, transmit, sell, rent, or share personal information such as your name, email address, phone number, precise location, contacts, photos, audio recordings, health data, device identifiers, advertising identifiers, or usage analytics.

Waveful does not use advertising SDKs, analytics SDKs, tracking SDKs, or third-party crash reporting services in the current app build.

2. Data Stored Locally on Your Device

Waveful may store certain app preferences locally on your device so the app can function properly. This may include:

• Selected app language
• Sound category and preset preferences
• Timer settings
• Mixer settings
• Breathing guide preferences
• Sleep routine notification settings
• Personalization settings such as sleep state, noise sensitivity, and focus style

This information stays on your device. It is not sent to Waveful, our servers, or third parties.

3. Data Retention

Because Waveful does not collect or store personal data on external servers, we do not retain personal data outside your device.

Local app preferences remain on your device only for as long as the app is installed or until you delete the app data. If you uninstall Waveful, your locally stored app preferences are deleted by the operating system according to Apple iOS or Android behavior.

If your device operating system provides an option to clear app storage or app data, using that option will also delete Waveful's locally stored preferences.
