Privacy Policy

Numa: Baby Sleep Sounds · Effective 3 October 2026

Who we are

Numa is a free Android app that plays calming sounds for babies. It is developed and published by the developer listed on Numa's Google Play page ("we", "us"). This policy explains how Numa handles information.

Information we collect

None. Numa does not collect any personal or device information. Specifically, Numa does not:

• require an account, email address, name or sign-in of any kind;
• use analytics, crash reporting, advertising or tracking tools;
• use the advertising ID;
• access your location, contacts, photos, files, microphone or camera;
• connect to the internet. The app does not even request internet permission, and every sound is stored inside the app.

Information stored on your device

To be useful, Numa remembers a few things only on your phone:

• your favorite sounds;
• your recently played sounds;
• your settings, such as default volume, sleep timer, fade-out and theme.

This information never leaves your device through Numa and is never sent to us. You can remove it at any time by clearing Numa's storage in Android settings or by uninstalling the app.

If you have turned on Android's own device backup, Android may include these settings in your personal Google backup, as it does for most apps. That backup is controlled by you and Google under Google's terms; we cannot access it.

Permissions

Numa asks Android for only what it needs to play sound reliably:

• Foreground service (media playback): keeps sound playing when the screen is off or you switch to another app, and shows the playback controls in your notifications and on the lock screen.
• Wake lock: stops the phone from interrupting playback while it sleeps.

None of these permissions give Numa access to personal information.

Sharing and selling

Because we collect no data, we have nothing to share, sell or transfer to anyone.

Children

Numa is designed for parents and caregivers to use for their babies. It collects no information from anyone, including children, and contains no ads, in-app purchases or links to outside services.

Third parties

Numa contains no third-party advertising, analytics or tracking software. Google Play, which you use to download the app, has its own privacy policy.

Changes to this policy

If this policy changes, we will update this page and the effective date above. If Numa ever started handling data differently, we would say so clearly here before that happened.
