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 require an account and we do not directly collect your name, email address, phone number, precise location, contacts, photos, audio recordings, health data, or payment card details.

Waveful uses Google AdMob / Google Mobile Ads SDK to display advertisements. Google may collect or process data such as approximate location, device identifiers, advertising data, product interaction data, crash logs, and performance data for advertising, measurement, analytics, fraud prevention, security, and service improvement purposes.

On iOS, Waveful uses Apple's AppTrackingTransparency framework where required before data is used for tracking across apps and websites owned by other companies.

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

Waveful does not operate user accounts or store personal data on our own external servers.

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.
