1. Introduction

Welcome to Quizwall ("we," "our," or "us"). This Privacy Policy explains how EntrovaLabs ("Company") collects, uses, discloses, and safeguards your information when you use our mobile application Quizwall (the "App").

Please read this Privacy Policy carefully. By using the App, you agree to the collection and use of information in accordance with this policy. If you do not agree with the terms of this Privacy Policy, please do not access or use the App.

2. Information We Collect

2.1 Information You Provide Directly

2.2 Information Collected Automatically

2.3 Information We Do NOT Collect

We expressly do not collect:

• ❌ Financial information (payments handled by Apple)
• ❌ Biometric data

3. Apple Screen Time API Usage

3.1 How We Use Screen Time

Quizwall uses Apple's Screen Time API (Family Controls framework) to:

• Display a list of installed apps for you to select which apps to block
• Apply temporary restrictions to selected apps until you complete a quiz
• Remove restrictions after successful quiz completion

3.2 Important Privacy Protections

Apple's Screen Time API is designed with privacy in mind:

• We cannot see which specific apps you have installed
• We cannot see how much time you spend in any app
• We cannot access any data from your blocked apps
• We only receive opaque tokens that Apple uses to manage restrictions
• All blocking happens locally on your device through Apple's system

3.3 Data Stays on Your Device

Your blocked app selections are stored only on your device using Apple's secure frameworks. This data is:

• Never transmitted to our servers
• Never shared with third parties
• Deleted when you uninstall the App

4. How We Use Your Information

We use the information we collect to:

1. Provide Core Functionality - Generate personalized quiz questions, track your learning progress and streaks, enable app blocking and unlocking features
2. Improve the App - Analyze aggregated, anonymized usage patterns, fix bugs and improve performance, develop new features
3. Communicate with You - Send push notifications (if enabled), respond to support requests, notify you of important updates
4. Maintain Security - Prevent fraud and abuse, enforce our Terms of Service, protect user accounts

5. Third-Party Services

5.1 Services We Use

5.2 What We Share

We share only the minimum necessary data with third parties:

• RevenueCat: Anonymous user ID and subscription status
• OpenRouter and AI model providers: Quiz subject, difficulty, and language preferences (no personal identifiers)

We never sell, rent, or trade your personal information to third parties for marketing purposes.

6. Data Retention

6.1 Account Deletion

You can delete your account at any time:

• In the App: Settings → Delete Account, available while you have active access
• By email: send a deletion request to privacy@entrovalabs.com, including if you no longer have an active subscription. We may ask for information needed to identify your account before deleting it.

Uninstalling the App or cancelling your subscription does not by itself delete your account.

When you delete your account:

• All your personal data is permanently deleted from our servers within 30 days
• Quiz history, achievements, and statistics are erased
• Your former referral code can no longer be used
• This action is irreversible

7. Data Security

We implement industry-standard security measures to protect your data:

• Encryption in Transit: All data transmitted between the App and our servers uses TLS 1.3 encryption
• Encryption at Rest: Sensitive data is encrypted in our database
• Secure Authentication: Device-based authentication with no passwords stored
• Access Controls: Limited employee access to user data on a need-to-know basis
• Regular Audits: Periodic security reviews and updates

However, no method of transmission over the Internet or electronic storage is 100% secure. While we strive to protect your information, we cannot guarantee absolute security.
