Privacy Policy

Last Updated: August 25, 2026

At maken.dev, we take your privacy seriously. This Privacy Policy explains how BattleCall ("we", "our", or "the app") collects, uses, and protects your information when you use our mobile application.

                🔒 Key Principle: Everything personal — your goals, alarms, recordings and streak — stays on your 
                device. maken.dev operates no servers and never receives that data. The only things that leave your device are 
                anonymous usage analytics, purchase verification, and (if you choose AI Coach) the text used to write your wake-up message.
            

1. Information We Collect

1.1 Information You Provide

When you use BattleCall, you may provide the following information, which is stored locally on your device only:

Personal Goals: Your name, life goals, motivational statements, and daily plans
Alarm Data: Alarm times, labels, categories, and unlock method preferences
Audio Recordings: Voice memos you record for custom alarm sounds (stored locally)
Media Files: Custom audio or video files you choose as alarm sounds
QR Code Data: QR codes you generate for alarm dismissal challenges
Usage Statistics: Your alarm completion streak and history (stored locally)

1.2 Automatically Collected Information

The app automatically collects the following technical information:

App Installation Date: To track your free trial period (stored locally)
Device State: To ensure alarms function properly (wake locks, audio state)
Analytics Events: Which screens you open and which options you pick — alarm type, sound mode, ringtone, unlock method, and purchase events. These never include your name, goals, alarm labels, voice recordings, or QR code contents
Device & App Info: Device model, Android version, language, country, and app version, recorded alongside analytics events
Advertising ID: Your device's resettable Android advertising identifier, used to measure our advertising campaigns
Crash Logs: Anonymous diagnostic data to improve app stability

2. Permissions We Request

🔔

Notifications (POST_NOTIFICATIONS) Required to show alarm notifications and remind you of scheduled alarms.

⏰

Schedule Exact Alarms (SCHEDULE_EXACT_ALARM) Required to trigger alarms at precise times you set. This permission is essential for alarm functionality.

🖥️

Display Over Other Apps (SYSTEM_ALERT_WINDOW) Required to show the ringing screen on top of whatever app is open when an alarm fires.

📺

Full-Screen Notifications (USE_FULL_SCREEN_INTENT) Required to open the alarm full-screen on your lock screen instead of as a small notification.

🔊

Foreground Service (FOREGROUND_SERVICE, FOREGROUND_SERVICE_MEDIA_PLAYBACK) Required to keep the alarm sound playing reliably for as long as the alarm is ringing.

🎤

Microphone (RECORD_AUDIO) Only used if you choose to record custom voice memos for alarm sounds. Recordings are stored locally on your device.

📷

Camera (CAMERA) Only used if you choose QR code scanning as an alarm unlock method. No photos are stored or transmitted.

🔋

Wake Lock (WAKE_LOCK) Required to wake your device and keep the screen on when an alarm rings.

🎵

Audio Settings (MODIFY_AUDIO_SETTINGS) Required to set alarm volume to maximum to ensure you hear your alarm (Ultra Volume).

3. How We Use Your Information

Your personal information is used on your device for the following purposes:

Alarm Functionality: To schedule, trigger, and manage your alarms and reminders
AI Coach Feature: To generate personalized motivational messages using your goals and preferences
User Experience: To remember your preferences, track your streak, and provide a personalized experience

Anonymous, non-personal information is used for:

Product Decisions: Aggregated analytics tell us which features are actually used
Ad Measurement: Your advertising ID lets Google attribute app installs to our own campaigns
App Improvements: Anonymous crash data is collected to fix bugs and improve performance

4. Third-Party Services

4.1 Google Gemini AI

BattleCall uses Google Gemini AI to generate personalized AI coach messages and text-to-speech audio. When you use the AI Coach feature:

Your name, goals, and daily plans are sent to Google's Gemini API to generate motivational content
This data is transmitted securely over HTTPS
Google may process this data according to their Privacy Policy
You can opt out of AI Coach features and use traditional alarm sounds instead

⚠️ Important: When using AI Coach features, your goals and daily plans are temporarily sent to Google's servers for AI processing. If you prefer complete privacy, use the Ringtone, Voice Memo, or Custom Media sound modes instead.

4.2 Firebase Analytics & Advertising ID

BattleCall uses Google Firebase Analytics to understand how the app is used and to measure our advertising:

Anonymous events are logged: screens opened, alarms created and completed, and which options you chose (alarm type, sound mode, ringtone, unlock method, purchases)
Device model, Android version, language, country, and app version are recorded alongside those events
Your device's Android advertising ID is collected so Google can attribute app installs to our campaigns and build audience segments
Your name, goals, alarm labels, voice recordings, and QR code contents are never included
Google processes this data according to their Privacy Policy

                🎯 Ad Tracking Opt-Out: You can reset or delete your advertising ID at any time in
                Android Settings → Privacy → Ads. Deleting it stops advertising-based measurement for this app.
            

4.3 RevenueCat (Subscription Management)

BattleCall uses RevenueCat to manage premium subscriptions and in-app purchases. When you make a purchase:

Your anonymous app user ID and purchase receipt are shared with RevenueCat to verify your entitlements
RevenueCat does not receive your name, email, or other personally identifiable information
All payment processing is handled entirely by Google Play — we never have access to your card details
RevenueCat processes data according to their Privacy Policy

4.4 Google Play In-App Review

After a few successful alarms, BattleCall may ask whether you'd like to rate the app. If you agree, Google Play's own review sheet opens inside the app.

Any review you write is submitted to and stored by Google Play, not by us
Google never tells us whether you left a review or what it said
Only your answer to our own question ("Rate", "Maybe later", "Don't ask again") is saved locally, so we know not to keep asking

4.5 Expo Platform

BattleCall is built using Expo/React Native framework. Expo may collect anonymous analytics data about app crashes and performance. This data does not contain any personal information.

5. Data Storage and Security

5.1 Local Storage

All your personal data (alarms, goals, recordings, preferences) is stored locally on your device using secure storage mechanisms:

AsyncStorage: For app settings and user preferences
SharedPreferences: For alarm configurations (Android)
File System: For audio recordings and custom media

5.2 Data Backup

Your app data may be included in Android's automatic backup system. You can disable this in your device's backup settings if desired.

5.3 Security Measures

Data is stored locally and protected by your device's security (PIN, pattern, biometrics)
maken.dev operates no servers of its own. Data leaves your device only for Google Gemini (AI Coach), RevenueCat (purchase verification), and Firebase Analytics (anonymous usage), always over HTTPS
Audio recordings are stored locally and never uploaded without your explicit action
QR code data is generated and stored locally on your device

6. Data Sharing and Disclosure

We do NOT share, sell, or disclose your personal information to third parties, except:

With Your Consent: When you explicitly choose to export or share data (e.g., sharing a QR code)
For AI Features: When you use AI Coach, data is sent to Google Gemini API as described above
For Purchases: An anonymous user ID and purchase receipt are shared with RevenueCat to verify subscription entitlements
Legal Requirements: If required by law, court order, or government regulation
Analytics & Ads: Anonymous usage events and your resettable advertising ID are sent to Google Firebase Analytics, as described in section 4.2
App Store Analytics: Anonymous usage data may be shared with Google Play Store for app improvement

                ✅ No Data Selling: We will NEVER sell your personal data to advertisers, data brokers, 
                or any third parties. The only identifier shared for advertising purposes is your resettable Android advertising ID, 
                used solely to measure our own campaigns.
