Privacy Policy

1. Information We Collect

1.1 Account Data (Optional)

If you choose to create an account, we collect:

• Email address: For authentication and account recovery
• Name: To personalize your experience
• Registration date: For internal management

1.2 Usage Data

We automatically collect:

• Exam history: Your scores and answers to display statistics

1.3 Purchase Data

In-app purchases are processed by Apple/Google. We only receive:

• Subscription status (active/inactive)
• Subscription type (weekly, monthly, lifetime)
• We do NOT have access to payment data (credit card, etc.)

2. How We Use Your Data

• Provide and improve our services
• Sync your progress across devices
• Send important notifications about your account
• Aggregate analytics to improve the app

3. Third-Party Services

We use the following services:

• Firebase (Google): Authentication, database, analytics
• Apple StoreKit: Payment processing
• Google Play Billing: Payment processing (Android)

These services have their own privacy policies that we recommend reviewing.

3.1 AI Vision Feature (Premium)

When you use the optional AI Vision feature, the photo you capture and the question you submit are sent to our backend on Google Cloud (Firebase Cloud Functions, EU region) and forwarded to Google's Gemini API for analysis. Photos and questions are processed in memory only and are NOT stored on our servers; we keep only operational metadata (anonymous user id, model used, latency, prompt length).

AI Vision is OFF by default. Before the first use you see an in-app notice explaining that photos are sent to a third-party AI service, and you must explicitly grant camera permission. You can stop using AI Vision at any time and no further data will be sent.

Please avoid capturing faces, license plates or other personal data — the feature is intended for traffic signs, road markings and driving situations only. Data sent to Google is processed under the Google Gemini API Terms and Google Privacy Policy.

4. Storage and Security

• Your data is stored on secure Firebase (Google Cloud) servers
• We use encryption in transit (HTTPS/TLS)
• Data access is restricted to necessary functions
• Passwords are never stored in plain text

5. Your Rights (GDPR)

As a user, you have the right to:

• Access: Request a copy of your data
• Rectification: Correct inaccurate data
• Erasure: Request deletion of your account and data
• Portability: Receive your data in a readable format
• Objection: Object to data processing

To exercise these rights, contact us via email.
