Privacy Policy
Effective date: September 3, 2026
Your privacy is important to us. This Privacy Policy explains what data SleepOS, published by xCube Labs, collects, how we use it, and the choices you have. By using SleepOS you agree to this policy.
1. Data we collect
We collect only what we need to run SleepOS and help you sleep better. The table below summarizes the data we collect and why.
| Data | Collected | Shared with third parties | Purpose |
|---|---|---|---|
| Name | Yes (Google sign-in) | No | Account, app functionality |
| Email address | Yes (Google sign-in) | No | Account, app functionality |
| Phone number | Yes (phone OTP) | No | Account, app functionality |
| User IDs | Yes | No | App functionality, analytics |
| Purchase history | Yes (in-app purchases) | No | App functionality |
| Health & fitness (sleep, heart rate, HRV, resting HR) | Yes (Health Connect / Apple Health) | No | App functionality |
| App interactions | Yes (Firebase Analytics) | No | Analytics |
| Device / other IDs (advertising ID, push token, install ID) | Yes | No | Analytics, app functionality |
| Voice / sound recordings (Luna) | Yes | No | App functionality |
We do not collect location, contacts, photos, or files, and we do not use Health Connect or Apple Health data for advertising.
2. How we use your data
- To provide core features — sleep tracking, sleep score, smart alarm, wind down and Luna coaching.
- To personalize your plan and Luna’s guidance.
- To process in-app purchases and manage your subscription.
- To understand how the app is used and improve it, using privacy-preserving analytics.
- To keep the service secure and prevent fraud or abuse.
We do not use your personal data to serve you third-party advertising.
3. Health & fitness data
With your permission, SleepOS reads sleep and heart-rate data from Health Connect on Android or Apple Health on iOS — specifically sleep sessions, heart rate, resting heart rate and heart-rate variability (HRV). We request read access only; we never write to these systems.
Health data is used solely to power your sleep insights inside SleepOS. It is never sold and never used for advertising. Health data read from Health Connect or Apple Health also lives in those systems, which you control separately in your device settings — deleting your SleepOS account removes only SleepOS’s copy. For a full breakdown, see our Health Data Disclosure.
4. Voice data (Luna)
When you talk to Luna, your microphone is used only during an active conversation to power the voice experience. Voice audio is processed by our voice provider acting on our behalf to generate Luna’s responses. We do not sell this data or use it for advertising.
5. How your data is shared
We do not sell your data. We share data only with service providers who process it on our behalf to run SleepOS, under contracts that limit their use of it:
- Google Firebase — authentication and privacy-preserving analytics.
- Our backend — to store your account, sleep history and preferences.
- Our voice provider — to process Luna voice conversations.
- Google Play / Apple App Store — to process subscriptions and purchases.
These providers are processors acting on our behalf, not third-party recipients who use your data for their own purposes.
6. Data security
Your data is encrypted in transit using HTTPS/TLS. We apply reasonable administrative, technical and organizational measures to protect your information. No method of transmission or storage is 100% secure, but we work to protect your data and limit access to it.
7. Data retention & deletion
You can clear your sleep history at any time in the app under Profile → Privacy & Data → Reset My Data, and you can export your data from the same screen. To delete your entire account and its data, follow the steps on our Account & Data Deletion page — we permanently delete your account and associated data within 30 days of a verified request. Some records (for example, purchase records we must keep for legal, tax or accounting reasons) may be retained as required by law.
8. Your choices & rights
- Access and export your data from within the app.
- Reset or delete your data, or delete your entire account.
- Manage permissions (microphone, notifications, Health Connect / Apple Health) in your device settings.
- Manage or cancel your subscription in Google Play or the App Store.
9. Children’s privacy
SleepOS is not directed to children under 13, and we do not knowingly collect personal data from children under 13. If you believe a child has provided us with personal data, please contact us and we will delete it.
10. Changes to this policy
We may update this Privacy Policy from time to time. When we make material changes, we will update the effective date above and, where appropriate, notify you in the app. Your continued use of SleepOS after an update means you accept the revised policy.
