This Privacy Policy describes how Green Line Test (“we”, “us”, or “our”), operated at greenlinetest.app, collects, uses, and protects your information when you use our service.

Information We Collect

Account Information

When you sign in with Google OAuth, we collect the following information from your Google account:

Email address
Display name
Profile photo URL

This information is stored in Firebase Firestore along with your account data, including credit balance and usage statistics.

Photos You Upload

When you upload a photo for analysis, the image is sent to a third-party AI service (Replicate API) for processing. Your photos are not permanently stored on our servers. They are transmitted to the AI model for analysis and the result is returned to you. We do not retain, archive, or use your uploaded photos for any purpose beyond completing the requested analysis.

Payment Information

Payments are processed securely through Stripe. We do not store your credit card number, CVV, or other sensitive payment details. Stripe handles all payment data in accordance with PCI-DSS standards. We only receive confirmation of successful transactions and basic transaction metadata (such as amount paid and payment timestamp).

How We Use Your Information

We use the information we collect to:

Authenticate your account and maintain your session
Process your photo analyses
Track your credit balance and usage history
Process payments for credit purchases
Communicate with you about your account if necessary

Cookies and Tracking

We do not use cookies for tracking or advertising. The only cookies used are those strictly necessary for authentication session management (keeping you signed in).

Third-Party Services

We use the following third-party services:

Google OAuth – for authentication
Firebase (Google) – for user data storage and authentication
Replicate API – for AI-powered image analysis
Stripe – for payment processing

Each of these services has their own privacy policies governing how they handle your data.

Data Sharing and Selling

We do not sell, trade, or rent your personal information to third parties. We only share data with the third-party services listed above to the extent necessary to provide our service.

Data Security

We take reasonable measures to protect your personal information. Account data is stored securely in Firebase Firestore, and all communications with our service are encrypted via HTTPS.

Data Retention

Your account information is retained for as long as your account is active. Uploaded photos are not permanently stored and are only used transiently during analysis. If you wish to delete your account and associated data, please contact us.

Children’s Privacy

Our service is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that a child under 13 has provided us with personal information, we will take steps to delete that information.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify users of any material changes by updating the “Last updated” date at the top of this page. Your continued use of the service after any changes constitutes acceptance of the updated policy.
