🚀 Join my OMR Battle Room!

Welcome to OMR ("App", "we", "our", or "us"). We are committed to protecting your personal privacy. This Privacy Policy explains what information we collect, how we use it, and how your data is protected across our offline practice features and online real-time Battle Rooms.

1. Information We Collect

A. Google Sign-In Account Information (Optional)

When you choose to use the Battle Room feature, we use Google Sign-In to authenticate your account. We receive basic profile information including your Name, Email Address, Profile Photo URL, and unique User ID. This data is used solely to identify your room submissions, host battle rooms, and display rankings on live leaderboards.

B. Battle Room Data & Test Answers

When you create or join an online Battle Room, your submitted answers, test scores, completion timestamps, and calculated ranks are synchronized using Firebase Cloud Firestore. If a host uploads a test paper PDF, it is securely stored in Firebase Storage for exam review.

C. Offline Practice Data (Stored Locally)

Standard solo OMR practice tests, answer key templates, scoring configurations, and past test history for offline practice are stored strictly on your local device storage. We do not upload your offline practice scores or personal files to any server.

D. Document Scanner

When using our built-in Document Scanner to scan physical question papers, all image processing and edge detection is performed 100% on-device using local machine learning models. Scanned PDF documents remain saved in your private device storage unless you explicitly choose to attach them to a Battle Room.

2. Third-Party Services & Analytics

We use trusted third-party services that may collect information used to identify you or deliver essential app services in compliance with their privacy policies:

Google Sign-In & Firebase (Google LLC): Used for account authentication, real-time database synchronization (Cloud Firestore), and secure file hosting (Firebase Storage).
Google Analytics for Firebase (Google LLC): Used to measure anonymous feature engagement, app performance, and exam usage trends (e.g. Battle Room participation, PDF question paper adoption). Analytics data is aggregated and does not disclose your personal test answers.
Google AdMob (Google LLC): Used to display non-intrusive advertisements and rewarded video passes ("Ad-Free Session Pass") to keep the app 100% free. AdMob may collect device identifiers and advertising metrics in accordance with Google's Advertising Policies.
Google Play Services: Used for app runtime, licensing, and security infrastructure.

3. Cloud Data Retention & Auto-Cleanup

To respect user privacy and optimize storage:

7-Day Battle Review Policy: PDF test papers attached to completed Battle Rooms are automatically and permanently deleted from Firebase Storage 7 days after exam completion.
Local Data Control: You can clear your offline scoreboards, review PDF files, and scanned documents anytime from within the app settings or by clearing app data.

4. Security & Data Protection

We prioritize the security of your data. All communication between the app, Google Authentication, and Firebase Cloud Services is encrypted using industry-standard Transport Layer Security (TLS/HTTPS). We do not sell, rent, or trade your personal information with any third parties.

5. User Controls, Account Choices & Data Deletion

You can use solo OMR practice 100% anonymously without signing in.
You can sign out of your Google account at any time directly from the Battle Room hub screen.
You can delete or leave any battle room you have created or joined.
Account & Data Deletion Request: You have the right to request permanent deletion of your profile, cloud account records, and associated battle room data. To submit a deletion request, please contact us at surya.phani1729@gmail.com with your registered email address. We will permanently delete your records from our cloud databases within 30 days.

6. Changes to This Policy

We may update our Privacy Policy periodically to reflect new features or legal requirements. Updated policies will always be accessible within the app and on our official web portal at https://omr-app-1729.web.app/.
