Privacy Policy

Last updated: September 25, 2026

1. Introduction

Codereltech L.L.C. ("we", "our", or "us") operates the Slumber Wave mobile app and this website. This Privacy Policy explains what information we collect when you use the app or the website, and how we use, disclose, and protect it.

2. Information we collect

2.1 Information you provide

Account information, if you create an account: your email address, your name, and the sign-in method you use (Apple, Google, or email). If you sign up with email, we store your password only in hashed form. If you continue as a guest, we create an account tied to a device identifier.
What you save in the app, such as your favorites and saved mixes
Contact information, when you contact our support team or send a message through the contact form on this website (your name, email address, subject, topic, and message)
Payment information for Premium features (processed by the App Store or Google Play)

2.2 Information we collect automatically

Device information (model, operating system, unique identifiers)
Usage data (features you use, listening patterns, interaction data)
Log data (access times, pages viewed, crashes)
Analytics data that helps us improve the app's performance
Session recordings: we record how you move through the app's screens (session replay) to find usability problems and errors. Mixpanel and Microsoft Clarity record only while analytics is turned on. Sentry records about 1% of sessions and every session in which an error occurs.

2.3 Motion and health data

If you use Morning Summary, Slumber Wave uses your phone's motion sensors (accelerometer) to estimate how long you slept. This estimate is made on your device. The results for each night (for example the start and end time, the sounds you played, and the estimated time it took you to fall asleep) are saved to your account so you can see them in Morning Summary. We do not store raw motion sensor readings. On iOS, you can choose to let Slumber Wave read sleep data from Apple Health. We only read this data. We never write to Apple Health or change anything in it. Apple Health data is read on your device and is not uploaded. We never use motion or health data for advertising, we never sell it, and we never share it with third parties. You can withdraw access at any time in your device settings (iOS: Settings > Privacy & Security > Health / Motion & Fitness).

2.4 Advertising measurement

We use Apple Ads attribution to see which of our ads led to an install or a subscription. On iOS, we ask for your permission before any tracking across other companies' apps and websites. You can change this choice at any time in iOS Settings.

2.5 Push notifications

If you allow notifications, we use a push notification provider (OneSignal) to send them. You can turn them off at any time in your device settings.

3. How we use your information

We use the information we collect to:

Provide and maintain our sleep and relaxation audio service
Show you your own listening and sleep history, such as which sounds you fell asleep to fastest
Improve and optimize the app
Answer your questions and support requests
Send you important updates about the service
Detect and prevent fraud or abuse

4. Health disclaimer

Slumber Wave is not a medical device, a diagnostic tool, or a therapeutic service. Its audio content is meant to help with relaxation and sleep, but it does not replace professional medical advice. For any health concern, always consult a healthcare professional.

5. Data sharing

We do not sell your personal information. We may share data with:

Service providers that help us run the app
Analytics partners that help us understand how the app is used
Legal authorities, when the law requires it

These are the service providers and analytics partners the app uses:

Google Firebase: sign-in, analytics, crash reports, and remote configuration
Mixpanel: analytics and session recordings
Microsoft Clarity: session recordings
Sentry: crash and error reports, including session recordings
RevenueCat: subscription management. It receives your account ID, email address, name, sign-in method, device model, operating system, and language setting.
OneSignal: push notifications
Apple App Store and Google Play: payments

We link the identifiers that RevenueCat, Mixpanel, and OneSignal use for you, so that subscription events can be matched with analytics and notification records.

6. Data security

We use industry-standard security measures to protect your information. However, no method of transmitting or storing data electronically is 100% secure, so we cannot guarantee absolute security.

7. Data retention

We keep your personal information only for as long as we need it for the purposes described in this policy. When we no longer need it, we delete it securely or anonymize it.

8. Your rights

Depending on where you live, you may have the right to:

Access the personal data we hold about you
Ask us to correct inaccurate data
Ask us to delete your data
Object to or restrict our processing of your data
Receive your data in a portable format (data portability)
Withdraw your consent at any time

In the app, you can turn off analytics under Data & Privacy. This stops Mixpanel, Microsoft Clarity, and Firebase Analytics, including their session recordings. Analytics is turned on by default. Crash and error reporting (Firebase Crashlytics and Sentry) is not affected by this setting. You can also delete your account in the app. This deletes your account and its data on our servers.

9. Children's privacy

Our service is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has given us personal data, please contact us and we will take steps to delete it.

10. Third-party services

Our app may contain links to third-party services. We are not responsible for how these third parties handle privacy. We encourage you to read their privacy policies.

11. Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will post the new policy on this page and update the "Last updated" date. We will announce major updates through in-app notifications.

12. Contact us
