Last updated: December 2024

1. Introduction

Welcome to Phone Detox (also known as ScreenLock Detox). We are committed to protecting your privacy and personal data. This privacy policy explains how we collect, use, store, and protect your information when you use our application.

2. Information We Collect

2.1. Locally Stored Data

The Phone Detox application stores all your data locally on your device. We DO NOT collect, store, or transmit any personal data to our servers. The data stored includes:

Lock screen settings: Lock mode, duration, time range, lock screen type
Whitelist applications: Applications you choose not to block
Missed notifications: Information about notifications that were hidden when the lock screen was active (stored locally only, maximum 100 notifications)
Wallpaper settings: Category and URL of wallpapers you have selected
Battery animation settings: Vibration and sound options
Selected language: Interface language

2.2. Permissions

For the application to function properly, we require the following permissions:

Display over other apps (Overlay): To display the lock screen overlay on other applications
Usage access (Usage Stats): To track which application is open and apply the lock at the right time
Notification access (Notification Listener): To hide notification content when the lock screen is active (optional)
Post notifications (POST_NOTIFICATIONS): To display lock status and important notifications
Read phone state (READ_PHONE_STATE): To detect incoming calls and automatically pause the lock
Set wallpaper (SET_WALLPAPER): To set wallpaper for the system lock screen (optional)
Internet connection: Only to load wallpapers from Pixabay (if you use this feature), display advertisements, and sync with Firebase services

2.3. Firebase Services Data Collection

Our application uses Google Firebase services to improve app functionality and user experience. The following Firebase services may collect certain information:

Firebase Analytics: Automatically collects anonymous usage statistics including:
- App events (e.g., screen views, button clicks, feature usage)
- Device information (device model, operating system version, app version)
- General location data (country/region based on IP address, not precise location)
- App performance metrics (crash-free users, engagement metrics)
This data is collected anonymously and cannot be used to identify you personally.
Firebase Crashlytics: Automatically collects crash reports and error logs when the app crashes or encounters errors, including:
- Stack traces and error messages
- Device information (model, OS version)
- App state at the time of crash
This helps us identify and fix bugs to improve app stability. Crashlytics is disabled in debug builds.
Firebase Remote Config: Used to remotely configure app settings (such as ad unit IDs) without requiring an app update. This service may collect device identifiers to deliver personalized configurations.

Firebase data is stored on Google's servers and is subject to Google's privacy policy. You can learn more about Firebase data collection at https://firebase.google.com/support/privacy.

2.4. Google AdMob Advertising Data

Our application uses Google AdMob to display advertisements. AdMob may collect and use the following information to provide personalized ads:

Advertising ID (AAID/IDFA): A unique, resettable identifier used for advertising purposes
Device information: Device type, model, operating system, and version
Location data: General location (country/region) based on IP address for ad targeting
App activity: Information about ads you interact with (views, clicks)
Network information: IP address, network type (Wi-Fi, mobile data)

AdMob uses this data to:

Show you relevant advertisements
Prevent fraud and abuse
Measure ad performance and effectiveness
Comply with legal requirements

You can opt out of personalized advertising by adjusting your device's advertising settings:

Android: Settings → Google → Ads → Reset advertising ID or Opt out of Ads Personalization
Note: You will still see ads, but they may be less relevant to your interests

3. How We Use Information

All data is used solely to provide application features:

Apply lock screen settings according to your preferences
Track application usage time to trigger the lock at the right time
Hide notifications when the lock screen is active (if you enable this feature)
Store and display missed notifications when you unlock
Load and display wallpapers from Pixabay (if you choose to use this)
Display advertisements from Google AdMob to keep the application free
Analyze app usage patterns through Firebase Analytics to improve features and user experience
Monitor and fix app crashes through Firebase Crashlytics to ensure app stability
Remotely configure app settings through Firebase Remote Config
