SomniSense Privacy Policy & Terms of Service

1. Data Collection and Usage

1.1 Data Collection

When you use SomniSense, we collect the following categories of data:

• Account Information. Email address, password (stored only in hashed form on our servers, never in plaintext), and a server-issued account identifier. You provide this when you register.
• Device Information. Your device model (e.g. "Pixel 7"), Android operating system version, app version, app language preference, and timezone. We do not collect your IP address as a stored field, your Android Advertising ID (AAID), Android ID, IMEI, phone number, SIM serial, MAC address, or any precise hardware fingerprint.
• Sleep Statistics (Aggregated). When a sleep monitoring session ends, your phone computes per-minute and per-night statistics — snoring count, snoring duration, dB level (average and peak), classified breathing-irregularity event counts (paused-breathing and reduced-breathing events bucketed by duration), BRI (Breathing Irregularity Index — equivalent to the per-hour AHI scale used in clinical literature, reported here as an informational wellness value, not a diagnosis), session start time, end time, and total duration. These aggregated numbers may be synced to your SomniSense account for cross-device history, trend analysis, and backup.
• Sleep Sound Data (Audio). SomniSense uses your phone's microphone during a sleep session to record audio. The audio is processed locally on your device by an on-device machine-learning model that produces the statistics above. Audio recordings are never uploaded, transmitted, or stored on our servers in the current release. See Section 1.4 for details.
• Subscription Information. When you subscribe to SomniSense Pro through Google Play Billing, we receive your purchase token, product SKU (e.g. pro_monthly, pro_annual), purchase status, and renewal expiry date. We use this only to verify your subscription and unlock Pro features. We do not receive your payment card number, billing address, or any payment instrument details — those stay with Google.
• Device Push Token. When push notifications are enabled, Firebase Cloud Messaging issues your device a push token. We store this token on our servers so we can send you the notifications you have enabled. The token does not identify you personally outside of our system.
• User-Provided Profile and Goal Data. When you complete onboarding or edit your profile, we collect age range bucket, gender (optional), height, weight, sleep concerns selected from a predefined list, bedtime / wake-time preferences, and any health goals you set within the app. This is used solely to personalize your in-app experience.
• In-Session Questionnaire Data. Pre-sleep factors (alcohol, caffeine, exercise, stress, late meal, medication) and tonight's improvement choices (side sleeping, head elevation, nasal aid, CPAP, anti-snore pillow, relaxation) you optionally tag for a session.

1.2 Service Tiers and Feature Access

1.3 Permission Usage

The following permissions are declared in the app and used as described:

• Microphone (RECORD_AUDIO). Required to capture sleep sounds for on-device analysis. Audio is processed locally; no audio leaves your device.
• Foreground Service Microphone (FOREGROUND_SERVICE, FOREGROUND_SERVICE_MICROPHONE). Required by Android 14+ to keep the sleep monitoring service active in the background while your screen is off.
• Notifications (POST_NOTIFICATIONS). Used to display the persistent "monitoring is active" notification, your morning sleep report notification, and subscription renewal reminders. You may revoke this permission at any time in Android Settings.
• Internet, Network State, Wi-Fi State. Used to sync your sleep statistics to your account, verify your subscription with Google Play, and receive push notifications. No audio is transmitted.
• Wake Lock. Keeps the CPU active during a sleep session so monitoring is not interrupted by system sleep.
• Battery Optimization Exemption (REQUEST_IGNORE_BATTERY_OPTIMIZATIONS). With your explicit consent, prevents Android Doze mode from killing the sleep monitoring service mid-session.
• Boot Completed. Re-registers your scheduled bedtime reminders and weekly summary worker after your phone restarts.
• Exact Alarm (SCHEDULE_EXACT_ALARM). Used only to fire your user-set bedtime reminder at the exact time you chose.
• Phone State (READ_PHONE_STATE). Used only to detect when an incoming or outgoing phone call begins so the recorder can pause and resume automatically. We do not read your phone number, call log, or contacts.
• Modify Audio Settings. Used to configure the microphone capture parameters for accurate analysis.
• Google Play Billing. Required by Google Play Billing to process your subscription.

We do not request: precise or background location, file system access (MANAGE_EXTERNAL_STORAGE), the list of apps installed on your device (QUERY_ALL_PACKAGES), Bluetooth, contacts, calendar, SMS, camera, or body sensors.

1.4 Sound Data Collection

To analyze your sleep, SomniSense captures audio from your phone's microphone during an active sleep session. The audio is used as follows:

• On-Device Analysis. Audio is fed in real time into TensorFlow Lite models running entirely on your phone. The models output snoring counts, breathing-irregularity event classifications, and dB measurements.
• Local-Only Storage. All audio recordings are processed and stored locally on your device only, in the app's private storage area, which is not accessible to other apps. We do not upload or transmit your audio data to external servers.
• Local Retention. Free users: audio clips for the most recent 7 nights are retained; older clips are automatically deleted by the app. Pro users: audio clips for the most recent 90 nights are retained. You can manually delete any individual clip or all audio at any time from Settings → Data Management.

1.5 Data Usage

We use the data described above only for the following purposes:

• Operating the sleep monitoring, reporting, and trend features of the app.
• Maintaining your account and authenticating your sign-in.
• Verifying your Google Play subscription status and unlocking Pro features.
• Sending the in-app notifications you have enabled.
• Diagnosing crashes and improving app stability (using only non-personal device information; we do not run a third-party crash analytics SDK in this release).
• Communicating with you about service issues, security alerts, and material policy changes.

We do not use your data for behavioural advertising. We do not profile you for targeted advertising. We do not sell your personal information.

2. Data Storage and Security

2.1 Data Storage

• On Your Device. All sleep audio, all per-minute analysis rows, all sleep records, your settings, and a local copy of your account profile are stored in the SomniSense app's private storage on your Android device. Other apps cannot read this data.
• On Our Servers. Your account profile (email, hashed password, account ID), aggregated sleep statistics, subscription status, and FCM push token are stored on our servers (operated for SomniAI LLC) so that you can sign in on a new device and see your history. Servers are located in the United States.

2.2 Data Retention Periods

• Account data. Retained while your account is active. When you delete your account in-app, via our web account-deletion page, or by emailing us, we delete your account record and associated personal data within 30 days, except where retention is required by law.
• Sleep statistics on our servers. Free users: retained for 7 days rolling. Pro users: retained indefinitely until you manually delete them or close your account.
• Audio recordings. Stored only on your device. Free users: 7-day local rolling retention. Pro users: 90-day local rolling retention. Both can be cleared manually at any time. We do not store audio on our servers.
• Push token. Retained while you have notifications enabled. Cleared when you disable notifications, sign out, or delete the app.

2.3 Data Management

• View. All your sleep data is visible in the Reports and Trends pages within the app.
• Delete. Settings → Data Management; Settings → Delete Account. If you no longer have the app installed, use our web account-deletion page.
• Export. Single report PDF (Pro feature). Account-level data export available on request.

2.4 Data Security

• In Transit. All network traffic between the app and our servers uses HTTPS (TLS 1.2+).
• On the Server. Account passwords are stored only as salted hashes. Sleep statistics are stored in access-controlled databases.
• On the Device. All data is stored within the Android app sandbox and is not accessible to other apps without root access.
• Payment Information. All subscription payments are processed through Google Play Billing. We do not see, store, or transmit your payment card or billing details.
• Security Updates. We update the app regularly to patch security issues. Please keep the app updated through Google Play.

3. Data Sharing and Disclosure

We do not sell your personal information.

We share data only with the following service providers, only as necessary to operate the service, and only the data categories listed:

Recipient	Country	Data Shared	Purpose

We may also disclose your information when legally required to do so — for example, in response to a valid court order, subpoena, or government request — or when we believe in good faith that disclosure is necessary to protect our rights, your safety, or the safety of others.

We do not integrate Google Analytics, Firebase Analytics, Firebase Crashlytics, Adjust, AppsFlyer, Mixpanel, Amplitude, Sentry, Facebook SDK, TikTok SDK, or any other third-party advertising, attribution, or analytics SDK in this release.
