Legal & Policies

Terms of Service

Last updated: June 2026

1. Acceptance of Terms

By accessing and using Nextra plugins (including Nextra.rhino and Nextra.gh) and the Nextra.studio web platform, you agree to be bound by these Terms of Service. If you do not agree, do not use our services.

2. "As-Is" Software and Limitation of Liability

The software and services are provided "AS-IS" and "AS-AVAILABLE" without any warranties of any kind, either express or implied, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, or non-infringement.

Nextra and its developers shall NOT BE LIABLE for any direct, indirect, incidental, special, consequential, or punitive damages resulting from your use of or inability to use the software. This includes, but is not limited to: loss of data, corrupted 3D models, failed Grasshopper definitions, project delays, or financial loss. You use these AI-generated scripts and geometries entirely at your own risk. Always verify AI-generated geometry and code before applying it to production models.

3. Acceptable Use

You agree not to reverse engineer the plugins, bypass token billing mechanisms, abuse the API infrastructure, or use the services for any illegal activities.

Refund Policy

1. Strict No-Refund Policy

Due to the digital and consumable nature of our services (API tokens and API access), all sales are final. We do not offer refunds, partial refunds, or credits for any subscriptions or token packs purchased, regardless of usage.

2. Exceptions (System Faults)

The only exception to this policy is in the event of a verified, catastrophic system fault on our end that entirely prevents the delivery of purchased tokens. In such rare instances, refunds or token credits may be issued at our sole and absolute discretion after a technical review.

3. Subscription Cancellations

You may cancel your monthly subscription at any time via the Customer Portal. Cancellation will prevent future billing, but you will retain access to your plan until the end of your current billing cycle. No prorated refunds are provided for mid-cycle cancellations.

Privacy Policy

1. Data Collection

We collect minimal personal data necessary to provide our services. This includes your email address (for authentication and billing) and your payment information (processed securely via Stripe).

2. API Keys and Encryption (BYOK)

If you utilize the Bring Your Own Key (BYOK) feature, your Google Gemini API key is heavily encrypted before being stored in our database. We cannot view your raw API key, and it is only decrypted dynamically during plugin execution to authenticate your requests with Google.

Disclaimer: Using the BYOK system is entirely at your own risk. While we take extensive security measures to encrypt your keys, Nextra assumes no liability for any unauthorized usage of your Google Cloud account. If you are not comfortable accepting this risk, please do not use the BYOK feature.

3. Usage Data & LLM Interactions

We track API request volumes (token usage) strictly for billing and rate-limiting purposes.

Important Note regarding AI Data: The inputs (prompts, geometry data) you send to the plugins, and the resulting outputs generated by the LLM, may be saved on our servers. We reserve the right to use this anonymized interaction data to train, refine, and improve the Nextra system over time. If you do not agree with your inputs and outputs being saved or used for system improvements, you must not use our services.

4. Third Parties

We do not sell your personal data. We only share data with essential infrastructure providers: Stripe (for payment processing) and Google Cloud (for LLM inference).
