Terms of Service

The service

Querizer is a SQL learning platform that generates practice databases, challenges, and hints. The service is provided as-is, with no uptime or accuracy guarantees.

Your account

You're responsible for your account and any activity on it. Don't share credentials. If you suspect unauthorized access, let us know.

Acceptable use

Don't:

• Scrape, abuse, or overload the service.
• Try to extract prompts or model outputs at scale.
• Use Querizer to generate content unrelated to learning SQL.
• Reverse-engineer or attack the platform.

Violations may result in suspension or termination of your account.

Content

• Your queries: you own them. We process them to provide hints and grading.
• Generated databases and challenges: you can use them freely for learning.
• The platform (code, prompts, UI): we own it.

Plans and billing

The Free plan is free. Paid plans (when available) are billed monthly via Stripe. You can cancel anytime — access continues until the end of the current billing period. No refunds for partial months.

Service changes

We may change the service, pricing, or features. Material changes will be communicated in-app or by email.

Termination

You can stop using Querizer at any time. We may terminate accounts that violate these terms.

Limitation of liability

Querizer is provided as-is, without warranty of any kind. We're not liable for any indirect, incidental, or consequential damages arising from your use of the service.
