Privacy Policy

Last updated: 10 March 2026

SQLLineage-AI ("we", "our", or "us") operates the website https://sqllineage-ai.com. This Privacy Policy explains how we collect, use, and protect information when you use our service.

1. Information We Collect

We collect the following categories of information:

Account information: If you register, we collect your email address and display name via Firebase Authentication (managed by Google).
Usage data: We record how many SQL analyses you have run in order to apply your plan's query limits.
SQL queries: Your SQL is sent to Google Vertex AI for analysis. We do not permanently store your raw SQL on our servers after analysis is complete.
Payment information (Pro plan): Payments are processed by Stripe. We never handle or store your card details — Stripe manages all payment data.
Log data: Standard server logs (IP address, browser type, pages visited) collected automatically by Google Cloud infrastructure.

2. How We Use Your Information

To provide the SQL lineage analysis service
To apply and enforce your plan's query limits
To process payments via Stripe for Pro subscriptions
To send transactional emails (e.g., account verification, password reset) via Firebase
To monitor service health and prevent abuse

3. Google Vertex AI Processing

Your SQL queries are transmitted to Google Vertex AI (a Google Cloud service) for analysis. This processing is subject to Google Cloud's Data Processing Addendum. We use Google Cloud's enterprise infrastructure, which applies strict data security and confidentiality controls.

4. Data Retention

We retain your account information for as long as your account is active. Query history is retained to support the query history feature for registered and Pro users. You may request deletion of your account and associated data at any time by contacting us.

5. Data Sharing

We do not sell your personal data to third parties. We share data only with:

Google Cloud / Firebase / Vertex AI — for authentication, hosting, and AI processing
Stripe — for payment processing (Pro plan)

6. Your Rights (GDPR)

If you are in the European Economic Area or the United Kingdom, you have the right to:

Access the personal data we hold about you
Request correction of inaccurate data
Request deletion of your data ("right to be forgotten")
Object to or restrict processing in certain circumstances
Data portability

7. Cookies

We use Firebase Authentication session cookies strictly necessary for login functionality. We do not use advertising or third-party tracking cookies.

8. Security

All data is transmitted over HTTPS. We use Google Cloud's security infrastructure, including encryption at rest and in transit. We follow security best practices and review our systems regularly.

9. Children's Privacy

Our service is not directed at children under the age of 13. We do not knowingly collect personal information from children.
