Fenzo - Acceptable Use Policy

Fenzo Acceptable Use Policy

Last Updated: May 11, 2026

Fenzo is designed to help people learn. This Acceptable Use Policy ensures that every user has a great experience by setting expectations for responsible use across all Subscription Plans.

AI-powered features like course generation, and intelligent widgets require significant computing resources. This policy exists to prevent extreme usage from degrading the experience for others, while ensuring that normal learners never notice a limit.

This Acceptable Use Policy is part of our Terms of Service. Terms defined in the Terms of Service have the same meaning when used here.


1. General Principles

We design for generous use, not restrictive use. Our goal is that the vast majority of users never encounter a limit. If you're a student studying for an exam, a professional upskilling, or a parent learning alongside your kids, you should be able to use Fenzo as much as you need without worrying about hitting a wall.

Acceptable use limits exist to prevent abuse, not to restrict learning. The limits described below are designed to catch automated systems, bulk extraction, and extreme edge cases that would consume disproportionate resources. They are not designed to limit genuine learning activity.

We enforce progressively, not punitively. If you approach a limit, we'll slow things down before we stop them. You'll see a notification before any action is taken, and in most cases, limits reset at the start of your next billing period.

2. Usage Limits

How Limits Work

Each paid Subscription Plan includes a monthly allocation of AI-powered interactions. AI-powered interactions include course generation, and AI-driven feedback within widgets. Your plan's allocation is consumed as you use these features across the Service.

The specific allocation for each plan is displayed on our pricing page and in your account dashboard, where you can see your current usage at any time. Limits reset at the start of each billing period.

Free Tier

Free users receive a limited number of lessons per month and a small number of AI-powered interactions to experience the platform's capabilities. Specific limits are displayed during signup and in your account dashboard.

Paid Plans

Paid plans include a significantly higher monthly allocation of AI-powered interactions. The exact allocations for each plan may be adjusted over time as we optimize the Service and are always reflected on our pricing page.

What Happens When You Reach a Limit

When you approach or reach your monthly allocation:

  • You'll see a clear notification showing your current usage and when your allocation resets.
  • AI-powered features may be temporarily limited until your next billing period or until you upgrade to a higher plan.
  • Non-AI features (browsing courses, reviewing completed lessons, using basic widgets) remain fully available regardless of your AI usage.
  • You will never lose access to courses you've already generated or lessons you've already completed.

3. Rate Limits (Throttling)

In addition to monthly usage allocations, Fenzo enforces short-term rate limits to protect infrastructure, prevent automated abuse, and ensure consistent performance for all users. Rate limits cap how quickly you can perform certain actions in a short window, regardless of your remaining monthly allocation.

Rate limits apply to actions such as course generation, AI interactions, login attempts, and password resets. If you hit a rate limit, you'll see a message indicating when you can try again. Rate limits reset on a rolling window.

These limits are set generously, normal human usage will not trigger them. They exist to catch automated scripts and bots, not active learners.

4. Prohibited Uses

Regardless of your Subscription Plan, the following uses are always prohibited and may result in immediate suspension:

Automated abuse. Using bots, scripts, browser automation, or any programmatic means to generate courses, interact with AI Features, or scrape content at scale. This includes using the Service through unofficial APIs, browser extensions that automate interactions, or any tool that simulates human activity.

Bulk extraction. Systematically downloading, copying, or extracting courses, widget content, or AI-generated material for redistribution, resale, or use outside the Service, except as explicitly permitted (e.g., PDF export for Max users).

Account sharing. Sharing login credentials to allow multiple individuals to use a single account.

Credential selling or resale. Selling, renting, or otherwise transferring access to a Fenzo account or Subscription Plan.

Abusing AI Features. Using AI Mentor, AI Evaluator, or course generation for purposes unrelated to learning, including generating content for commercial use, academic dishonesty, or harassment. Examples include:

  • Generating marketing copy, business proposals, or other non-learning content
  • Using AI Mentor to complete graded academic assignments for submission as your own work
  • Using AI Features to generate harmful, abusive, or illegal content
  • Attempting to extract the system prompts, model weights, or training methodology of our AI systems

Circumventing limits. Creating multiple free accounts to circumvent usage limits, using VPNs or other tools to evade geographic restrictions or rate limits, or exploiting bugs or vulnerabilities to gain unauthorized access to features or data.

5. How We Detect and Enforce

Detection

We use automated systems to monitor usage patterns and detect potential acceptable use violations. These systems look for signals such as:

  • Unusually high request volume in a short period
  • Patterns consistent with automated rather than human interaction
  • Multiple accounts from the same device or IP address
  • Usage patterns inconsistent with learning activity

Progressive Enforcement

When a potential violation is detected, we follow a progressive enforcement process:

1. Throttling. We first slow down the specific feature being overused. Other features remain unaffected.

2. Notification. We notify you via email and in-app message that unusual activity has been detected, along with guidance on how to stay within acceptable use expectations.

3. Temporary restriction. If the pattern continues after notification, we may temporarily restrict access to the specific feature for a defined period (typically 24-72 hours).

4. Account review. For severe or repeated violations, we may suspend the account pending review. We will contact you to discuss the situation before taking permanent action.

5. Termination. In cases of clear, intentional abuse (e.g., running automated scripts to bulk-extract content), we may terminate the account immediately per our Terms of Service.

Appeals

If you believe enforcement was applied in error, contact us at support@fenzo.ai. We review all appeals within 2 business days and will restore access if the enforcement was a false positive.

6. What Acceptable Use Looks Like in Practice

To give you a sense of what normal usage looks like versus what would trigger concerns:

A student studying for AP Chemistry (normal use): Generates 2-3 courses per week on different chemistry topics. Completes 3-5 lessons per day. Uses AI Mentor several times per week for guided problem-solving. This is within any paid plan's allocation.

A professional upskilling (normal use): Generates 1-2 courses per week. Completes courses in 2-3 sessions. Uses AI Mentor a few times per course for deeper understanding. This is light usage, within any plan.

A power learner studying 3 subjects simultaneously (heavy but normal use): Generates 5-8 courses per week across multiple subjects. Completes 8-10 lessons per day. Uses AI Mentor and AI Evaluator multiple times per day. This is heavy usage but genuine learning activity, the kind of usage our higher-tier plans are designed for.

An automated script generating courses for resale (abuse): Generates hundreds of courses in a few hours. No human interaction with any widgets. Downloads all content immediately. This would be detected within minutes and blocked.

7. Changes to This Policy

We may update this Acceptable Use Policy from time to time to reflect changes in the Service, usage patterns, or costs. Material changes will be communicated via email or in-app notice before they take effect.

We will never retroactively enforce new limits on existing month's usage, changes apply prospectively only.

8. Questions

If you have questions about this Acceptable Use Policy, what constitutes acceptable use for your particular situation, or if you need higher limits for a legitimate use case (e.g., a research project, a large classroom), please contact us at support@fenzo.ai. We're happy to work with you.
