Terms of Service

The Short Version

These Terms of Service ("Terms") govern your access to and use of prismhld.com and all associated services (collectively, "PRISM") operated by the PRISM team ("we", "us", "our"). Please read them carefully. By creating an account or using PRISM you agree to be bound by these Terms.

Acceptance of Terms

By accessing or using PRISM in any way, including browsing the website, creating an account, running a simulation, or submitting an evaluation, you confirm that:

• You are at least 16 years of age.
• You have read and agree to these Terms and our Privacy Policy.
• If you are accepting on behalf of an organisation, you have authority to bind that organisation to these Terms.

If you do not agree to these Terms, you must not use PRISM.

Description of Service

PRISM is an interactive system design simulator that allows users to:

• Build distributed system architectures on an interactive canvas
• Run traffic simulations and observe latency, error rates, and bottlenecks
• Complete guided learning modules and roadmap topics
• Take mock system design interviews with AI-generated MCQs and trade-off analysis
• Track evaluation history and scores over time

We offer free and paid subscription tiers. Feature availability varies by plan. We reserve the right to modify, suspend, or discontinue any feature or the service as a whole with reasonable notice where practical.

Accounts & Access

Registration: Some features require a registered account. You agree to provide accurate information during registration and to keep it up to date.

Credentials: You are responsible for maintaining the confidentiality of your password and for all activity that occurs under your account. Notify us immediately at hello@prismhld.com if you suspect unauthorised access.

One account per person: You may not create multiple accounts to circumvent usage limits or other restrictions.

OAuth sign-in: If you use Google or GitHub to authenticate, those providers' terms also apply. We receive only the minimum necessary profile data (name, email) from them.

Sharing: Subscription plans are for individual use. You may not share login credentials or plan benefits with others.

Acceptable Use

You agree not to use PRISM to:

• Violate any applicable law or regulation
• Attempt to gain unauthorised access to any system, network, or data
• Scrape, crawl, or systematically extract data from PRISM using automated means without prior written permission
• Reverse-engineer, decompile, or otherwise attempt to extract the source code or AI model weights underlying PRISM
• Overload or stress PRISM's infrastructure beyond normal usage (excessive API abuse, denial-of-service)
• Upload or transmit viruses, malware, or any harmful code
• Harass, threaten, or harm other users
• Use the platform in ways that violate the rights of third parties

We reserve the right to suspend or terminate access without notice for material violations of this section.

Intellectual Property

PRISM content: The PRISM platform — including the simulation engine, rule system, scoring models, UI, branding, and all software — is owned by us and protected by copyright and other intellectual property laws. You may not copy, distribute, or create derivative works from our platform without written permission.

Your content: The canvas designs, evaluation answers, and feedback you create remain yours. By using PRISM, you grant us a limited licence to store, process, and display your content solely to operate the service and to send relevant data to our AI provider (OpenAI) to generate features you request.

Feedback: Any suggestions, ideas, or feedback you submit may be used by us to improve the product without compensation or attribution.

AI-Generated Content

PRISM uses OpenAI's API to generate MCQ questions, evaluate trade-off answers, provide design feedback, and power other AI features. By using these features, you acknowledge:

• AI-generated content is provided for educational purposes only and may contain inaccuracies or omissions.
• Outputs should not be relied upon as professional advice (technical, legal, financial, or otherwise).
• Your inputs (canvas graphs, evaluation responses) are sent to OpenAI's servers and processed subject to their Usage Policies.
• We do not guarantee any particular quality, accuracy, or availability of AI-generated content.

We disclaim all warranties regarding AI-generated content to the fullest extent permitted by law.

Payments & Plans

Billing: Paid plans are billed via Razorpay. By purchasing a plan, you authorise us (via Razorpay) to charge your payment method for the applicable fees.

Cancellation: You may cancel your subscription at any time from your profile settings. Cancellation takes effect at the end of the current billing period; you retain access until then.

Refunds: Payments are generally non-refundable except where required by applicable consumer protection law. If you believe you were charged in error, contact us at hello@prismhld.com within 14 days of the charge.

Free plan limits: Free plans are subject to usage limits (simulations per month, evaluation runs, etc.) which may change. We will provide reasonable notice of material limit reductions.

Price changes: We may change subscription prices. Existing subscribers will receive at least 30 days' notice of a price increase before it takes effect for their next renewal.

Disclaimers

PRISM is provided "as is" and "as available" without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, or uninterrupted availability.

We do not warrant that:

• The service will be error-free or available at all times
• Simulation results accurately reflect real-world system behaviour
• AI-generated assessments are a reliable predictor of actual interview performance
• The platform is free from security vulnerabilities

Using PRISM to prepare for technical interviews does not guarantee interview success.

Limitation of Liability

To the maximum extent permitted by applicable law, PRISM and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of data, loss of revenue, or lost opportunity, arising out of or related to your use of the service.

Our total cumulative liability to you for any claim arising under these Terms shall not exceed the greater of: (a) the amount you paid us in the 12 months preceding the claim, or (b) USD $50.

Some jurisdictions do not allow certain liability exclusions. In those cases, our liability is limited to the fullest extent permitted by law.

Termination

By you: You may delete your account at any time via your profile settings. Upon deletion, your personal data will be removed in accordance with our Privacy Policy.

By us: We may suspend or terminate your access if you materially breach these Terms, engage in abusive behaviour, or if we discontinue the service. We will provide reasonable notice where feasible.

Provisions of these Terms that by their nature should survive termination (IP, disclaimers, liability limits, governing law) will do so.

Governing Law

These Terms are governed by and construed in accordance with the laws of India, without regard to conflict-of-law principles. Any dispute arising out of these Terms shall be subject to the exclusive jurisdiction of the courts in India.

If you are using PRISM from outside India, you do so voluntarily and are responsible for compliance with local laws.

Changes to Terms

We may update these Terms at any time. When we make material changes, we will update the "Last updated" date at the top of this page and, where appropriate, notify registered users by email or in-app notice.

Your continued use of PRISM after changes become effective constitutes acceptance of the revised Terms. If you disagree with the changes, your remedy is to stop using the service and delete your account.
