Privacy Policy

Struct, Inc. ("Struct", "we", "us", or "our") provides a text-to-3D simulation platform that helps teams build and simulate autonomous systems with hyper-accurate real-world data. This Privacy Policy explains how we collect, use, disclose, and safeguard information in connection with our websites, platform, and related services (collectively, the "Services").

By accessing or using the Services, you agree to this Privacy Policy and our Terms of Service. If you do not agree, please do not use the Services.

1. Information You Provide

• Account information (name, username, email, password).
• Profile and organization details (company, role, team).
• Payment information processed by our payment providers (we do not store full card details).
• Support communications, feedback, and survey responses.
• Simulation inputs and content: prompts, text, configuration files, 3D assets/meshes, textures, scene graphs, metadata, and any other content you upload or connect to the Services.

2. Information Collected Automatically

• Usage data (features used, clicks, pages viewed, session duration).
• Device and log data (IP address, browser type, OS, timestamps, referrer).
• Cookies and similar technologies to remember preferences and improve performance.
• Telemetry and performance metrics related to simulation runs (e.g., load times, memory usage, errors, job statuses), which help us improve reliability and debugging tools.

3. Information from Third Parties

• Identity and profile data from SSO/identity providers if you authenticate via those services.
• Analytics and attribution partners that help us understand site usage and marketing performance.
• Storage/CDN or model providers you connect to the platform at your direction.

• Provide, maintain, and secure the Services and your account.
• Process simulations, generate outputs, store assets, and deliver results.
• Improve and develop features, models, performance, and user experience.
• Detect, prevent, and address security incidents, abuse, and fraud.
• Provide customer support and respond to inquiries.
• Send transactional messages and, where permitted, product updates or marketing communications.
• Comply with legal obligations and enforce our Terms of Service.

Where required by law, we process personal data based on consent, contract performance, legitimate interests (e.g., to improve the Services), or legal obligations.

We use Brevo (formerly Sendinblue) to manage email subscriptions, newsletters, and certain web forms on our site (including embedded SIB forms). When you subscribe or submit a form, Brevo processes your email address, subscription preferences, IP address, and timestamp on our behalf to help deliver messages and maintain accurate consent records. You can unsubscribe at any time via the link in our emails or by contacting us at hello@struct.inc.

Brevo acts as our processor and may store data on servers outside your country. For details, please review Brevo’s privacy documentation at brevo.com/legal/privacypolicy.

You may provide prompts, training data, 3D assets, and other inputs to run simulations and generate outputs. You retain ownership of your inputs and outputs as between you and Struct, Inc., subject to the license you grant us to host, process, transmit, and display such content as needed to provide the Services.

We may collect limited telemetry about simulation runs to improve system reliability, safety, and performance. Unless you opt into data-sharing programs, we do not use your private assets or prompts to train our general-purpose models beyond what is necessary to provide the Services.

• Service Providers: infrastructure, storage/CDN, analytics, CI/CD, and customer support vendors.
• Enterprise Integrations: third-party tools and providers you connect at your direction.
• Legal and Safety: to comply with law, protect rights, or respond to lawful requests.
• Business Transfers: in connection with a merger, acquisition, or asset sale.

We do not sell personal information. We do not share personal data with third parties for their direct marketing without your consent.

We retain personal data for as long as necessary to provide the Services, comply with our legal obligations, resolve disputes, and enforce agreements. You may request deletion of your account data as described in the "Your Rights" section below.

We may process and store information in the United States and other countries where we or our service providers operate. Where required, we use appropriate safeguards (such as Standard Contractual Clauses) for cross-border transfers of personal data.

We employ technical and organizational measures designed to protect information against unauthorized access, disclosure, alteration, or destruction. However, no system is 100% secure, and we cannot guarantee absolute security.

We use cookies and similar technologies to operate and secure the Services, remember your preferences, and analyze usage. Types of cookies include:

• Essential cookies required for core functionality and security.
• Preference cookies to remember settings (e.g., language, UI preferences).
• Performance/analytics cookies to understand how the Services are used and to improve them.

You can control cookies through your browser settings. If you disable certain cookies, some features may not function properly. We do not respond to Do Not Track (DNT) signals at this time.

• Access, correction, and deletion of your personal data.
• Restriction or objection to certain processing where applicable.
• Portability of data in a machine-readable format where required by law.
• Opt-out of marketing communications via unsubscribe links or by contacting us.
• California/EEA/UK residents may have additional rights under local law.

To exercise your rights, contact us at hello@struct.inc. We may ask for verification of your identity before fulfilling requests.

The Services are not directed to children under 13 (or the minimum age required by your jurisdiction), and we do not knowingly collect personal information from children. If you believe a child has provided personal information to us, please contact us so we can take appropriate action.

The Services may contain links to third-party websites, services, or integrations. We are not responsible for the privacy practices of those third parties. We encourage you to review their privacy policies.

We may update this Privacy Policy from time to time. The "Last Updated" date reflects the most recent changes. Material changes will be communicated as required by law. Your continued use of the Services indicates your acceptance of the updated policy.
