By accessing or using Structa, you agree to be bound by these Terms of Service and our Privacy Policy. If you do not agree to these terms, please do not use our service.

Description of Service

Structa is an AI-powered database design platform that allows users to create database schemas using natural language descriptions. We provide tools to generate, visualize, and export database schemas in various formats.

Account Registration

To access certain features, you must create an account. You agree to:

• Provide accurate, current, and complete information
• Maintain the security of your password
• Accept responsibility for all activities under your account
• Notify us immediately of any unauthorized access

Subscription Plans

Fair Use Policy

Paid plans are marketed as "Unlimited*" but are subject to reasonable fair-use limits to ensure service quality and availability for all users. Fair-use limits are:

• Pro Weekly: 500 generations and 2M tokens per month
• Pro Monthly/Yearly: 3,000 generations and 10M tokens per month
• Lifetime: 2,000 generations and 8M tokens per month

Token-Based Soft Limits

For paid tiers, token limits are "soft caps" that trigger graceful degradation:

• Below 60% usage: Normal operation with best AI models
• 60-80% usage: Normal operation, usage monitored
• 80-100% usage: Automatic switch to secondary AI models
• Above 100% usage: Switch to most efficient models with slightly reduced output

Token degradation does NOT block your service - it ensures quality for all users while allowing you to continue working.

Generation Hard Caps

Generation caps are enforced as hard limits. If you reach your monthly generation cap, you will receive a message with options to:

• Wait until the next billing cycle (resets monthly)
• Contact support for higher limits if your use case requires it

Rate Limits

All tiers are subject to rate limits to prevent abuse and ensure service stability:

• 5 requests per minute
• 100 requests per hour
• Maximum 2 concurrent requests

Prohibited Usage

The following activities are explicitly prohibited and will result in account suspension or termination:

• Bulk automation: Using scripts, bots, or automated tools for non-human usage patterns
• Resale or white-labeling: Reselling our service or integrating it into your own product without authorization
• Account sharing: Sharing credentials across multiple users or organizations
• AI model training: Using our outputs to train competing AI models or services
• Service abuse: Intentionally degrading service quality for other users

Legitimate High-Volume Use

We welcome legitimate high-volume usage including agency work, team projects, educational courses, and open-source development. If your legitimate use case exceeds our fair-use caps, please contact us at support@trystructa.com to discuss custom enterprise plans.
