Sleep Relax – Privacy Policy
Last updated: 14 October 2026
This policy explains what data the Android app Sleep Relax (package name: com.impuladijital.sleeprelax), developed by Impula Dijital ("we"), accesses, why, what stays on your device, and what third-party services do.
In short: Sleep Relax has no server and no user accounts. Your listening history, favorites, mixes and sleep ratings stay on your device and are not sent to us.
1. Data stored on your device
The following data is stored only on your device, together with the app. It is not sent to our servers and is not collected by us:
Your preferences: language, sleep reminder settings (days and times), whether onboarding was completed.
Your favorite sounds and saved mixes (mix name and the level of each sound).
Listening data: daily listening time, monthly listening time per sound, listening streak and earned badges, the last sound or mix you played.
Your morning sleep ratings (the optional 1–5 rating you give). The monthly recap is generated on your device from this data.
A cache of your subscription status (whether it is active and when it was last verified).
You can delete this data by clearing the app's data or uninstalling it (see Section 9).
2. Permissions and why they are needed
Internet (INTERNET) and network state (ACCESS_NETWORK_STATE): needed to show ads (Google AdMob), manage subscriptions (Google Play) and download fonts. The app does not connect to a server of its own.
Advertising ID (AD_ID, ACCESS_ADSERVICES_*): used by Google AdMob to serve, limit and measure ads. You can reset or disable it in your device settings.
Wake lock (WAKE_LOCK), foreground service (FOREGROUND_SERVICE and FOREGROUND_SERVICE_MEDIA_PLAYBACK): keeps sounds playing without interruption while the screen is off and lets you control them from the notification and lock screen.
Notifications (POST_NOTIFICATIONS): used only for the sleep reminder you turn on and to show the playing sound in a notification. If you do not grant it, the app still works but no reminder is shown.
Run at startup (RECEIVE_BOOT_COMPLETED): re-arms your sleep reminder after the device restarts or the clock/time zone changes.
Google Play Billing (com.android.vending.BILLING): needed to purchase and verify the Premium subscription.
Reading Health Connect sleep data (READ_SLEEP): optional and off by default; it is requested only if you turn it on in Settings (see Section 4).
We do not request location, camera, microphone, contacts, storage or phone permissions.
3. Ads and consent (Google AdMob, UMP)
The free version shows ads through Google AdMob. For ad serving, limiting, measurement, fraud prevention and diagnostics, AdMob may process data such as your advertising ID, approximate location derived from your IP address, device and operating system information, and your interactions with ads, under its own responsibility. We do not receive this data; Google processes it as an independent controller.
In the European Economic Area, the United Kingdom and Switzerland (and elsewhere where required) we ask for your consent for ads through Google's User Messaging Platform (UMP). If you do not consent, ads run without consent-based personalization or are not shown. You can change your choice at any time under Settings > Ad privacy options.
Premium members do not see ads.
More information: how Google uses data when you use partner sites or apps (policies.google.com/technologies/partner-sites) and AdMob data disclosures (support.google.com/admob/answer/6128543).
4. Health Connect (sleep data) — optional
This feature is off by default. If you turn it on in Settings and approve it on the Health Connect permission screen, the duration of sleep sessions that your watch or phone recorded in Health Connect is read and shown in the weekly summary on the home screen.
Only read access (READ_SLEEP) is requested; nothing is ever written to Health Connect.
The data you read never leaves your device: it is not sent to our servers or to third parties, not used for advertising or analytics, and not stored permanently.
You can remove the permission at any time in Health Connect settings or turn the switch off in the app.
5. Subscriptions and payments (Google Play Billing)
Premium is purchased through Google Play. Your card or payment details are not passed to us; Google processes the payment. The app only learns from Google Play whether your subscription is active and its product ID, and caches that on your device. You can manage and cancel your subscription on the Subscriptions page in Google Play.
6. Other Google services
Fonts (Google Fonts): the app's fonts are downloaded through Google Play services; Google may process standard network and device information while doing so.
Google Play In-App Review: we may occasionally ask you to rate the app. That window belongs to Google and your rating is sent to Google Play.
Android Auto Backup: if turned on on your device, your app data (favorites, mixes, preferences, listening statistics) may be included in your Google account backup. This is a Google service and you can turn it off in Android settings.
7. Sharing
When you share a mix or the monthly recap card, the content (mix name and sound levels, or the recap image) is sent only through the app you choose, to the people you choose. It does not come to us. When you add a mix code you received from someone else, it is only saved on your device.
8. We do not sell or share your data
We do not sell, rent or share your personal data with third parties for our own purposes. Data processed by third-party services (Google AdMob, Google Play) is limited to the scope described above and is subject to their own privacy policies.
9. Retention, deletion and your rights
Retention: data stays only on your device until you delete it or uninstall the app. We hold no copy.
Deletion: use Android Settings > Apps > Sleep Relax > Storage > Clear data to delete all app data, or uninstall the app. You can delete the automatic backup in your Google account from the Google Drive/Android backup settings.
Ad choices: Settings > Ad privacy options; in your device's Google settings you can reset your advertising ID or turn off personalization.
Permissions: you can revoke any permission in your device settings.
Because we do not hold your personal data, access, correction or deletion requests are generally actions you can carry out yourself using the steps above. For questions about your rights under Turkey's Law No. 6698 (KVKK) and, where applicable, the GDPR, you can contact us. For data processed by Google, you can use Google's own tools.
10. Security
Data is kept in the app's storage on your device and protected by Android's app isolation. Communication with third-party services (AdMob, Google Play) uses encrypted connections (TLS). No system is entirely risk-free; we recommend protecting your device with a screen lock.
11. Children
Sleep Relax is not directed at children under 13 and we do not knowingly collect data from children.
12. Changes
We may update this policy. We will announce important changes in the app or on the Google Play page. The current version is on this page and under Settings > Privacy Policy in the app.
