Ce document est publié en anglais. La version anglaise fait foi.

Our privacy position. We collect only information reasonably needed to operate our business, deliver agreed services, protect our systems, and meet legal obligations. We do not sell personal information. We do not use confidential customer content to train general-purpose AI models unless a customer expressly authorizes that use in a written agreement.

1. Scope and accountability

This Privacy Policy applies to TeraSystemsAI LLC websites, business communications, payment interactions, and services that link to it. It does not replace a signed statement of work, data-processing agreement, business associate agreement, research protocol, or other service-specific contract. Where a signed agreement provides stronger or more specific protections, that agreement governs the covered engagement.

TeraSystemsAI LLC is based in Pennsylvania, United States. Depending on the context, we may act as a business collecting information for our own purposes or as a service provider or processor acting under a customer’s documented instructions.

Healthcare information. TeraSystemsAI does not treat every interaction as subject to HIPAA. We process protected health information only when the work is authorized, the parties have established the required contractual framework, and the applicable safeguards are in place. A website inquiry or ordinary business transaction should not include patient information or other sensitive clinical data.

2. Information we collect

Information you provide

  • Business and contact information: name, work email, organization, role, billing address, and information included in an inquiry or support request.
  • Transaction information: purchased service, invoice details, payment status, order-form or statement-of-work reference, and related accounting records.
  • Account and access information: account identifiers, authentication records, role assignments, and user preferences where an account-based service is available.
  • Professional information: resume, curriculum vitae, publication record, or other material submitted for employment, contracting, research, or collaboration.
  • Customer-provided content: documents, instructions, evidence, model artifacts, or other material submitted under an authorized engagement.

Information collected through website and service operation

  • IP address, browser type, device and operating-system information, timestamps, requested pages, and security or diagnostic logs.
  • Cookie or similar technology data when those technologies are used. We do not describe analytics, advertising, or tracking practices here unless they are actually enabled.
  • General location inferred from IP address where needed for security, fraud prevention, or service operation.

Information from other sources

We may receive business contact or engagement information from an organization that authorizes you to work with us, a payment processor, a professional network, a public research source, or a collaborator. We use that information only for the relevant business, research, security, or service purpose.

3. How we use information

  • Deliver services. Operate contracted workflows, support users, manage evidence and records, and provide agreed deliverables.
  • Manage business relationships. Respond to inquiries, prepare proposals, administer contracts, invoice customers, and maintain transaction records.
  • Protect systems and users. Authenticate access, prevent misuse, investigate incidents, maintain logs, and enforce authorization boundaries.
  • Improve reliability. Diagnose defects, assess system performance, and improve products using information appropriate for that purpose and consistent with applicable agreements.
  • Meet legal obligations. Maintain tax and accounting records, respond to lawful process, resolve disputes, and protect legal rights.
  • Communicate responsibly. Send service, security, administrative, or relationship communications. Marketing communications, where used, include a reasonable method to opt out.

4. AI systems, model training, and customer data

TeraSystemsAI develops and operates evidence-governed and uncertainty-aware systems for high-stakes environments. That work does not create permission to use customer information without defined authority.

  • We do not use confidential customer content to train a general-purpose model unless the customer has expressly authorized that use in writing.
  • Customer data is processed for the contracted purpose, within the agreed scope, access controls, retention terms, and deployment boundaries.
  • Where third-party model or infrastructure providers are used, their role and applicable controls are governed by the service configuration and relevant agreement.
  • De-identification or aggregation is not represented as risk-free. We use such methods only where appropriate and maintain safeguards proportionate to the data and purpose.
  • Our systems support human review and governed decision processes. A payment, upload, model output, or automated workflow does not by itself establish compliance, validation, approval, or production readiness.

5. How we disclose information

We do not sell personal information. We also do not disclose personal information for cross-context behavioral advertising.

We may disclose information in the following limited circumstances:

  • Service providers: vendors that support payment processing, hosting, email, security, professional services, or other necessary operations, subject to appropriate restrictions.
  • Authorized customer personnel: individuals designated by the customer to receive access, reports, invoices, or engagement communications.
  • Research or collaboration: only under an applicable agreement, authorization, ethics requirement, or consent process.
  • Legal and safety needs: where required by law or reasonably necessary to protect rights, systems, users, or the public.
  • Business transactions: in connection with a merger, financing, acquisition, reorganization, or transfer of assets, with appropriate confidentiality protections.
  • At your direction: when you or the relevant customer organization instructs or authorizes the disclosure.

6. Payments

Paid TERA plans and other purchases are processed by third-party payment processors, such as Stripe. When you pay, the payment processor collects and processes your payment-card details under its own privacy notice. TeraSystemsAI does not receive or store full payment-card numbers.

We receive limited transaction information, such as the plan or item purchased, the amount and currency, the payment status, the billing country or postal code where provided, and a processor reference. We use it to deliver the purchase, maintain accounting and tax records, prevent fraud, and respond to billing questions.

7. Retention

We keep personal information only for as long as reasonably necessary for the purposes described in this policy, unless a longer period is required or permitted by law. Retention depends on:

  • the nature of the information and why it was collected;
  • whether an account, subscription, or business relationship is active;
  • legal, regulatory, tax, accounting, or reporting requirements;
  • security, dispute-resolution, or investigation needs; and
  • deletion requests or withdrawal of consent, where applicable.

When information is no longer needed, we delete it, de-identify it, or keep it securely isolated until deletion is possible.

8. Security

We use administrative, technical, and organizational safeguards appropriate to the nature of the information, including access controls, encrypted connections for our websites and services, restricted administrative access, and logging.

No internet transmission or information system is completely secure, and we cannot guarantee absolute security. If you believe your account or information has been compromised, contact security@terasystems.ai.

9. Privacy choices and rights

Depending on where you live and whether a particular privacy law applies to TeraSystemsAI or the relevant processing activity, you may have rights to request access, correction, deletion, restriction, portability, or objection, and to withdraw consent where consent is the legal basis for processing.

These rights are not absolute. We may need to verify your identity, confirm your authority to act for an organization, retain records required for security, contractual, regulatory, tax, accounting, dispute-resolution, or legal purposes, or deny or limit a request where permitted by law. When we process information solely on behalf of a customer, we may direct the request to that customer or assist the customer in responding.

To submit a privacy request, email contact@terasystems.ai with the subject “Privacy Request.” Do not send passwords, authentication credentials, full payment-card numbers, patient records, government identifiers, confidential supervisory information, or other restricted data through ordinary email.

10. International data transfers

TeraSystemsAI is based in the United States. Information may be processed in the United States or in other locations where authorized service providers operate. Where an international transfer requires a recognized legal mechanism, we apply the mechanism appropriate to the specific relationship, jurisdiction, and processing activity. We do not represent that a particular transfer framework applies unless it has been implemented for the relevant service or engagement.

11. Children’s privacy

Our commercial websites, professional services, and high-stakes AI systems are not directed to children. We do not knowingly collect personal information from a child through these services without appropriate authorization and a legally permitted purpose. If you believe that a child has submitted personal information to us, contact us so that we can evaluate the matter and take appropriate action.

12. Third-party websites and services

Our website may link to or use third-party websites, payment providers, publishing platforms, repositories, communication services, or other external resources. Their privacy and security practices are governed by their own notices and agreements. A link, reference, or integration does not mean that TeraSystemsAI controls, guarantees, or endorses those practices.

13. Changes to this policy

We may revise this Privacy Policy when our services, systems, processing practices, risk controls, or legal obligations change. We will publish the revised version with an updated effective or “Last updated” date. Where required by applicable law or contract, we will provide additional notice or obtain consent before applying a material change.

Continued use of a service does not waive rights that cannot lawfully be waived and does not replace any notice, authorization, or consent required by applicable law.
