Privacy Policy for Sleep Sounds: White Noise

Effective date: November 7, 2026
Last updated: November 7, 2026

This Privacy Policy explains how AppMaven ("we", "us") handles information when you use the Sleep Sounds: White Noise Android app (the "App", package name com.appmaven.sleepstream). Please read it together with our Terms of Service.

1. Who is responsible

AppMaven is the developer of the App and is responsible for the information described in this policy that we control. Contact: hacong86@gmail.com. Google acts under its own terms and policies when it provides advertising, consent, Google Play and font services.

2. Information stored on your device

• Sleep journal: entries you add, such as the date, hours slept, a quality rating, the sounds and timer you used, and optional notes. Insights, charts and streaks are calculated on your device from these entries.
• Favorites and sessions: saved sound mixes and your last mix, so the App can resume it.
• Settings: language, the sleep goal you choose during onboarding, keep-screen-on, auto-restore, reminder choices and similar preferences.
• Unlock status: sounds or scenes unlocked for 60 minutes with a rewarded ad, and a cached copy of your Pro status.

All sounds are included in the App, so playing them does not send your listening activity to us. We do not transmit the information above to an AppMaven server.

3. Android backup

The App does not turn off Android's automatic app backup. Depending on your Android version and device settings, the App's data may be included in an encrypted backup to your own Google account and restored when you set up a new device. AppMaven cannot access those backups. You can manage backup in your device settings.

4. Advertising (Google AdMob)

The free version of the App shows ads through the Google Mobile Ads SDK: an app open ad when you open or return to the App, native ads in some screens, and rewarded videos that you choose to watch to unlock a premium sound or scene for 60 minutes. According to Google's data disclosure for this SDK, it automatically collects and shares:

• Approximate location estimated from your IP address (the App does not request GPS location);
• App interactions, such as app launches, taps and ad views;
• Diagnostics about app and SDK performance;
• Device or other identifiers, such as the Android advertising ID and app set ID.

Google uses this information for advertising, measurement, analytics and fraud prevention, and states that it is encrypted in transit. On supported Android versions the SDK may also use Android's privacy-preserving advertising features (Privacy Sandbox). Learn more in How Google uses information from sites or apps that use its services. Sleep Sounds Pro removes ads; data Google collected before that stays subject to Google's policies.

4.1 Consent

The App uses Google's User Messaging Platform (UMP). It checks with Google whether a consent message is required in your region, such as the European Economic Area, the United Kingdom or Switzerland. When it is, the message appears before ads load, and ads are requested only when Google's tool allows it. Your choice is stored on your device by Google's tool. When available for your region, you can review or change it in Settings → Privacy choices. Choosing non-personalized ads does not necessarily stop all ads or all ad-related processing.

4.2 Advertising ID

You can reset or delete your advertising ID in Android settings (usually Settings → Privacy → Ads, or Settings → Google → Ads; names vary by device).

5. Google Play purchases

Sleep Sounds Pro is a one-time purchase processed by Google Play Billing. Google handles your payment information under its own policies; we do not receive your card number or billing address. The App receives purchase details from Google Play, such as the product, purchase status and a purchase token, so it can unlock Pro, complete the purchase and restore it. It checks for an existing purchase when it starts and when you tap Restore Purchase. Your Pro status is stored on your device. Purchase records remain with Google Play.

6. Other Google services

• Google Fonts: the App's fonts are downloaded from Google's font servers the first time they are needed and then cached on your device. Google receives your IP address and basic request information when this happens. See the Google Fonts privacy FAQ.
• In-app review: if the App asks for a rating, Google Play shows the review screen and handles your review under its own policies. We do not receive your account details.

7. Notifications and permissions

• Notifications: for the media controls shown while sounds play, and for the bedtime, streak and night dim reminders you turn on. Reminders are scheduled on your device. You can turn them off in the App or in Android settings.
• Run at startup: to reschedule your reminders after the device restarts.
• Foreground service and wake lock: to keep sounds playing in the background or with the screen off, and to keep the screen on while audio plays if you choose that setting.
• Internet and network state: for ads, consent, Google Play purchases and fonts.
• Google Play billing and advertising ID: for purchases and ads (sections 4 and 5).
• Vibration: for haptic feedback.

The App does not request access to your microphone, camera, location, contacts or photos.

8. Sharing the App and contacting us

If you share the App, Android's share menu sends a link to the App's Google Play page to the app you choose. If you email us from the App, your email app sends the message, and we receive your email address and what you write. We use it only to reply and to handle your request.

9. How we use information

• To play sounds, save your mixes and journal, show insights and send the reminders you turn on, on your device.
• To show ads that keep the App free, and to measure ads and prevent fraud (through Google).
• To process and restore your Pro purchase (through Google Play).
• To answer you if you contact us, and to comply with legal obligations.

10. Legal bases (EEA, UK and Switzerland)

Where data protection laws such as the GDPR apply, we rely on your consent for personalized advertising and the related use of identifiers, performance of a contract to provide Pro features you buy, our legitimate interests in delivering non-personalized ads, security and fraud prevention, and legal obligations where the law requires processing. You can withdraw consent at any time in Settings → Privacy choices.

11. Sharing and sale of information

AppMaven does not sell your personal information for money. Information is received by Google as described in sections 4 to 6. Under some US state laws, such as the California CPRA, using advertising identifiers for personalized ads may be considered "sharing". You can limit this by deleting or resetting your advertising ID in Android settings and through Privacy choices where available. We may also disclose information if the law requires it.

12. Retention and deletion

• On your device: data stays until you delete it. Settings → Delete all data permanently removes your favorites, sleep entries and preferences and cancels scheduled reminders; your Pro purchase is kept. Clearing the App's storage or uninstalling the App also removes local data. An existing Android backup in your Google account is managed in your device settings.
• Google data: information collected by AdMob, UMP, Google Play and Google Fonts is kept and deleted by Google under its policies. Because the App has no account, AppMaven cannot link this data to you by name or email.
• Emails to support are kept in our mailbox as long as needed to handle your request. You can ask us to delete them.

The App does not create accounts, so there is no account to delete. Deleting data does not cancel or refund a Google Play purchase.

13. Your rights

Depending on where you live, you may have the right to access, correct, delete, restrict or object to the processing of your personal data, to data portability, to withdraw consent and to complain to a data protection authority. Most App data is only on your device and under your control. For data held by Google, use Google's privacy tools. For anything else, contact us at hacong86@gmail.com; we will not treat you differently for using these rights.

14. Children

The App is not directed to children under 13 (or the minimum age of digital consent in your country, if higher), and we do not knowingly collect personal information from them. If you believe a child has provided personal information to us, contact us and we will take appropriate steps.

15. International processing

Google may process information in countries other than your own, including outside Vietnam and the EEA, using the safeguards described in its own policies, such as Standard Contractual Clauses.

16. Security

Your data stays in the App's storage on your device and is protected by your device's own security. Google states that its SDK data is encrypted in transit. No method of storage or transmission is completely secure, so protect your device with a screen lock.

17. Changes to this policy

We may update this policy when the App or the services it uses change. The date above shows the latest version. Material changes may also be announced in the App or on the store listing.
