Privacy Policy

Loud Alarm – Solve2Wake

Effective Date: June 30, 2026

1. Introduction

This Privacy Policy explains how Loud Alarm – Solve2Wake ("we", "our", or "the App") handles information when you use our Android application. We are committed to protecting your privacy and being transparent about our data practices.

By using the App, you agree to the practices described in this Privacy Policy.

2. Information We Collect

We do not collect any personal information. The App does not require an account, login, or any personal details to function. Specifically:

• We do not collect your name, email address, phone number, or any personally identifiable information.
• We do not collect location data.
• We do collect anonymized usage analytics (such as screens viewed, challenges completed, and alarm settings used) to help us improve the App.
• We use Google Analytics for Firebase to process this usage data securely.
• We collect the Google Advertising ID (a resettable, anonymous identifier) solely for analytics purposes. This identifier does not contain personally identifiable information.

3. Data Stored Locally on Your Device

The App stores the following data locally on your device only to provide its core functionality:

• Alarm configurations: Time, days of the week, label, volume boost preference, wake-up check settings, and challenge configurations (e.g., math difficulty, challenge types, barcode value, rewrite text, and step count).
• Barcode images: If you use the Barcode Challenge feature, a photo of the barcode or QR code is captured and saved locally on your device. This image is used solely to help you identify and locate the physical barcode you need to scan to dismiss the alarm. These images are never transmitted to any server or third party.
• Sensor data: If you use the Step Counter or Shake challenges, the App temporarily reads motion sensor data (accelerometer and step counter) during the challenge. This data is processed in real-time on your device and is never stored or transmitted.
• App settings: Vibration preference, snooze settings, alarm volume, fade-in duration, and dark mode preference.

This data is stored using Android's Room database and DataStore Preferences. It remains entirely on your device and is never transmitted to any server or third party. If you uninstall the App, all locally stored data is automatically deleted.

4. Camera Usage & Barcode Images

The App requests camera permission solely for the Barcode Challenge feature. This feature allows you to set up an alarm that requires scanning a specific barcode or QR code to dismiss.

• The camera is used for real-time barcode/QR code detection using Google ML Kit's on-device barcode scanning.
• When you register a barcode for the Barcode Challenge, a photo of the barcode is captured and saved locally on your device. This image serves as a reference so you can easily find and scan the correct barcode to dismiss your alarm.
• Barcode images are stored only on your device in the App's private storage. They are never uploaded, transmitted, or shared with any server, third party, or external service.
• You can delete saved barcode images at any time by removing the associated alarm or clearing the App's data.
• All barcode processing happens entirely on your device.
• Camera permission is optional. The App functions fully without it if you do not use the Barcode Challenge feature.

5. Permissions Explained

The App requests the following Android permissions, all of which are used solely for core alarm functionality:

• Schedule Exact Alarm / Use Exact Alarm: Required to trigger alarms at the precise time you set.
• Post Notifications: Required to display alarm notifications when an alarm rings.
• Foreground Service (Media Playback & System Exempted): Required to play the alarm sound reliably and maintain alarm reliability, even when the App is in the background.
• Wake Lock: Required to wake the device screen when an alarm fires.
• Receive Boot Completed: Required to re-schedule your alarms after the device restarts.
• Vibrate: Required to vibrate the device when an alarm rings (if enabled in settings).
• Camera: Optional. Used only for the Barcode Challenge and Scan challenges (see Section 4).
• System Alert Window: Required to display the alarm screen over other apps and on the lock screen.
• Disable Keyguard: Required to dismiss the device lock screen so the alarm screen can be shown immediately.
• Use Full Screen Intent: Required to show the full-screen alarm activity when the device screen is off.
• Request Ignore Battery Optimizations: Ensures alarms fire reliably and are not delayed by battery optimization.
• Activity Recognition: Optional. Required for the Step Counter challenge to detect and count your steps.
• High Sampling Rate Sensors: Optional. Required for the Shake challenge to accurately detect shaking motion.
• Advertising ID: Used to collect an anonymous, resettable device identifier for analytics purposes (see Section 2).
• Billing: Required to process optional in-app purchases or donations securely via Google Play.
• Internet & Network State: Required to transmit anonymized analytics data to help improve the App.
• Accessibility Service: Optional. If enabled, the App uses an Accessibility Service solely to prevent the device from being powered off while an alarm is actively ringing. This service does not read, collect, or transmit any personal data, screen content, or keystrokes. It is active only during an alarm event.
• Device Administrator: Optional. If enabled via the "Prevent Uninstall" setting, the App registers as a Device Administrator solely to prevent its own uninstallation while alarms are active. This permission does not grant the App access to any personal data, device passwords, or other device management capabilities. No policies are enforced — the App only uses the side-effect that a device administrator cannot be uninstalled. You can disable this at any time from the App's settings when no alarm is ringing, or from your device's Settings → Security → Device Administrators.

6. Third-Party Services

The App uses Google ML Kit Barcode Scanning for on-device barcode recognition (Barcode/QR Code challenge). This library processes data entirely on your device and does not send any data to Google or any external server.

The App also uses Google ML Kit Image Labeling (Play Services variant) and Google ML Kit Object Detection for the Scan Sink and Scan Object challenges. These libraries use on-device machine learning to identify and locate objects through the camera. All image processing happens entirely on your device; no images or recognition data are transmitted to any server or third party.

The App uses Google ML Kit Pose Detection for the Push-Up challenge. This library uses on-device machine learning to detect body pose landmarks through the camera in real-time. All pose data is processed entirely on your device and is never stored or transmitted.

The App uses Google Analytics for Firebase to collect anonymized usage data (including the Google Advertising ID) to help us understand how users interact with the App. The Advertising ID is a resettable, anonymous identifier and is not used for personalized advertising. You can learn more about how Google uses data at Google's Privacy & Terms site. No advertising networks are integrated into the App.

The App uses Google Play In-App Review to occasionally prompt you to rate the App. This flow is handled entirely by the Google Play system and does not collect or transmit any additional data from the App.

7. Data Sharing

We do not share any personally identifiable information with third parties. Anonymized usage data (including the Advertising ID) is processed by Google Analytics for Firebase as described above. We do not sell any of your data. The Advertising ID is not shared with any advertising networks.

8. Children's Privacy

The App does not knowingly collect any personal information from anyone, including children under the age of 13. Since the App collects no personal data whatsoever, it is safe for users of all ages.

9. Data Security

All core alarm data generated by the App is stored locally on your device using Android's built-in secure storage mechanisms. Anonymized analytics data is transmitted securely over encrypted connections (HTTPS) to Firebase servers.

10. Data Retention and Deletion

All App data is stored locally on your device. You can delete all data at any time by:

• Clearing the App's data through your device's Settings → Apps → Loud Alarm → Storage → Clear Data.
• Uninstalling the App, which automatically removes all associated data.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated "Effective Date." We encourage you to review this page periodically for any updates.
