Privacy Policy

Last updated: July 27, 2026

SQL Designer ("we", "us", or "our") operates sql-designer.com. This Privacy Policy explains what information we collect, how we use it, and the choices you have.

1. Information We Collect

  • Account data: When you register, we collect your email address and, if you sign in via OAuth (Google, GitHub, GitLab), your name and profile picture from that provider.
  • Diagram data: The database schemas you create and save are stored on our servers and associated with your account.
  • Usage data: We collect anonymised analytics (page views, feature usage) via Google Analytics to understand how the product is used.
  • Local storage: Your authentication token is stored in your browser's localStorage so you stay logged in across sessions.
  • Billing and consent data: We store subscription and payment identifiers, amounts, currencies, statuses, consent text and version, acceptance time, IP address, and user-agent. Card details are processed by Robokassa and are not stored on sql-designer.com.

2. How We Use Your Information

  • To provide and improve the SQL Designer service.
  • To send transactional emails (email verification, account-related notices).
  • To analyse product usage and fix bugs.
  • We do not sell your personal data to third parties.

3. Shared Diagrams

If you choose to share a diagram via a public share link, anyone with that link can view it. You can revoke access at any time from within the diagram editor.

4. Data Retention

We retain your account and diagram data for as long as your account is active. You may request deletion of your account and all associated data by emailing us at dmitriy@sql-designer.com.

5. Third-Party Services

  • Google Analytics: Anonymised usage tracking. See Google's Privacy Policy.
  • OAuth providers: Google, GitHub, and GitLab if you choose to sign in with them.
  • Robokassa: Payment processing, recurring charges, and refunds for SQL Designer Pro.

6. Cookies

We do not set tracking cookies ourselves. Google Analytics may set its own cookies subject to Google's policies. We use localStorage (not cookies) for authentication.

7. Security

We take reasonable technical measures to protect your data. However, no method of transmission over the internet is 100% secure.

8. Children

SQL Designer is not directed at children under 13. We do not knowingly collect personal data from children.

9. Changes to This Policy

We may update this policy from time to time. The "Last updated" date at the top will reflect any changes. Continued use of the service after changes constitutes acceptance.
