Vibe Check - AI Relationship Message Analyzer ("the App," "we," "us," or "our"), published by EmpathySphere.
Summary
Vibe Check is a free, ad-supported Android app that uses AI to analyze text messages and chat screenshots. We collect minimal data needed to operate the app. Your messages are analyzed by AI in real-time and not stored on our servers. We never sell your personal data.
1. Information We Collect
1.1 Account Information
When you sign in with Google, we receive:
- Google account email address and display name -- used for account identification and profile display
- Google profile photo URL -- displayed in your profile
- Firebase Authentication UID -- unique identifier for your account
We do not collect passwords. Authentication is handled entirely by Google Sign-In and Firebase Authentication.
1.2 Messages and Screenshots You Submit
When you use Vibe Check to analyze a message:
- Text messages you paste are sent to OpenAI's API for analysis via our secure cloud proxy
- Chat screenshots you upload are first processed on your device using Google ML Kit (on-device OCR) to extract text, then the extracted text is sent to OpenAI's API
- Messages are processed in real-time and are not stored on our servers after analysis is complete
- OpenAI processes data per their API data usage policy -- API inputs are not used to train their models
1.3 App Usage Data
We collect the following through the app:
- Analysis history -- your past analysis results (category, explanation, input preview) stored locally on your device (Room database) and synced to Firebase Firestore for cloud backup
- Engagement data -- streak count, gem balance, achievements, daily challenge progress, Vibe Score
- Referral data -- your referral code and referral history (stored in Firestore)
- Notification preferences -- your opt-in/out choices for push notifications
1.4 Automatically Collected Data
- Firebase Analytics -- anonymous event data (e.g., analysis completed, share tapped, achievement unlocked) for understanding app usage patterns. No personally identifiable information is included in analytics events.
- Crash logs and diagnostics -- collected via Firebase for stability monitoring and bug fixes
- Device identifier (ANDROID_ID) -- used locally on your device for SharedPreferences integrity verification (HMAC-SHA256). This ID is not sent to our servers.
- FCM token -- Firebase Cloud Messaging device token for delivering push notifications, stored in Firestore tied to your account
- Advertising ID -- collected by Google AdMob for serving ads, subject to your GDPR consent preferences
2. How We Use Your Information
- Provide AI analysis -- process your text messages and screenshots through OpenAI to deliver relationship analysis results
- Maintain your account -- sync gems, streaks, achievements, and history across sessions
- Serve advertisements -- display banner, interstitial, and rewarded video ads via Google AdMob (our sole revenue source)
- Send notifications -- streak reminders, achievement alerts, weekly reports (only if you opt in)
- Improve the app -- use anonymous analytics to understand feature usage and fix bugs
- Prevent abuse -- rate limiting, server-side gem validation, and integrity checking
- Referral rewards -- track referral codes to credit gem bonuses to referrers and referees

4. Advertising and GDPR Consent
Vibe Check is a free, ad-supported app. We use Google AdMob to serve advertisements including banner ads, interstitial ads, and rewarded video ads.
- GDPR compliance: For users in the EU/EEA/UK, we use Google's User Messaging Platform (UMP) to request consent before initializing ads. You can choose personalized or non-personalized ads.
- Ad personalization: If you consent, AdMob may use your Advertising ID and device information to serve personalized ads. If you decline, non-personalized ads are served instead.
- No ads are loaded before your consent preference is resolved.
- You can update your ad consent preferences at any time through your device settings.
5. Virtual Currency (Gems)
The app uses a virtual currency called "Gems" for in-app features. Important details:
- Gem balances are managed through a server-authoritative system -- all gem transactions are validated by our Cloud Function to prevent manipulation
- Local gem data is protected by HMAC-SHA256 integrity checking using a device-bound key (APP_SECRET + ANDROID_ID)
- Gems have no real-world monetary value and cannot be exchanged for real currency
- Tampering with gem balances may result in account flagging and server-side balance reset
6. Data Storage and Security
6.1 Where Your Data is Stored
- On your device: Analysis history (Room database), gem balance, streaks, settings (SharedPreferences)
- In the cloud: Account data, gem balance, streaks, achievements, referrals (Firebase Firestore)
- Not stored: Message content submitted for analysis -- processed in real-time, not retained
6.2 Security Measures
- All API communications use HTTPS encryption in transit
- Firebase App Check with Play Integrity verifies app authenticity
- Server-side rate limiting (10 requests/minute, 200 requests/day) prevents abuse
- Firestore Security Rules enforce data isolation between users
- Prompt injection detection on our cloud proxy sanitizes malicious inputs
- R8 code obfuscation in release builds
7. Data Retention
- Account data: Retained while your account is active. Deleted upon account deletion request.
- Analysis history: Stored locally on your device and in Firestore. Deleted with your account.
- Message content: Not retained after real-time analysis. Not stored on our servers.
