Privacy Policy
How Quantisage collects, uses, shares, and protects personal and company data across our website and the Quantisage AI platform.
Last updated: June 5, 2026
Overview
Quantisage LLC (“Quantisage”, “we”, “us”) respects your privacy. This Privacy Policy explains what personal data we collect, why we collect it, who we share it with, and the choices and rights you have. It applies to our website at quantisage.ai (the “Site”) and to the Quantisage AI platform, including our proprietary SAGE engine (together, the “Platform”).
Two different roles. For data we collect about visitors, prospects, and account users (for example through the Site, marketing, and account administration), Quantisage acts as a controller and this Policy governs. For operational, supply-chain, and emissions data that a customer or its integrations submit to the Platform for carbon measurement, validation, and reporting, Quantisage acts as a processor acting on the customer’s instructions; that processing is governed by our Data Protection Addendum and the customer’s agreement with us, and the customer is responsible for the privacy notices given to its own people and value-chain contacts.
Information we collect
Information you provide. Your name, work email, company, role, and similar contact and account details when you request a demo, subscribe, register, contact us, or take part in events.
Billing information. Billing contact, billing address, and limited payment details. Card payments are handled by our payment processors; we do not store full card numbers.
Platform content. Operational, financial, supplier, and emissions data that you or your integrations supply to the Platform for carbon measurement, validation, and reporting. This is primarily company data, but it may include limited personal data such as the names, business contact details, and job titles of your personnel or your suppliers’ contacts.
Technical and usage data. Device, browser, IP address, log data, and information about how the Site and Platform are used, collected to operate, secure, and improve the services.
Cookies and similar technologies. See “Cookies” below.
How we use information
We use personal data to: respond to enquiries and provide support; create and administer accounts; provide, operate, secure, and improve the Site and Platform; perform carbon calculations, validation, and reporting at your direction; process payments; send service communications and (where permitted) updates you have requested; understand usage through analytics; and meet our legal, tax, and contractual obligations.
Legal bases (where GDPR or UK GDPR applies). We rely on: performance of a contract with you; your consent (for example, for certain marketing and non-essential cookies, which you can withdraw at any time); our legitimate interests in running, securing, and improving our business; and compliance with legal obligations.
How we use data with our AI models
We treat customer data with care. We do not use a customer’s confidential data or identifiable personal data submitted to the Platform to train AI models that are made available to other customers, except on the customer’s documented instructions. We may use aggregated and de-identified data — which does not identify you, any individual, or any single customer — to operate, secure, evaluate, and improve the Platform, including to develop emission factors, benchmarks, and methodologies.
Sharing
We do not sell personal data, and we do not “share” it for cross-context behavioural advertising. We disclose personal data only:
- To service providers and sub-processors who process data on our behalf (for example, hosting, infrastructure, analytics, payments, and support), under contracts requiring appropriate safeguards and limiting their use of the data to providing services to us;
- To validators, auditors, and assurance providers that you engage or direct us to work with in connection with your filings;
- For legal and safety reasons, where required by law, regulation, legal process, or governmental request, or to protect our rights, users, or the public;
- In a corporate transaction, such as a merger, acquisition, financing, or sale of assets, subject to this Policy continuing to govern the personal data transferred.
Cookies
We and selected providers use cookies and similar technologies to operate the Site, remember preferences, measure performance, and improve content. Essential cookies are necessary for the Site to function. Where required by law, we ask for your consent before setting non-essential cookies, and you can manage your choices at any time through our cookie settings or your browser controls.
International transfers
We are based in the United States and may process and store personal data in the United States and other countries. Where we transfer personal data from the EEA, the UK, or Switzerland to a country that has not been recognised as providing an adequate level of protection, we rely on appropriate transfer mechanisms, such as the European Commission’s Standard Contractual Clauses and the UK Addendum, together with additional safeguards where needed. Further detail for customer data is set out in our Data Protection Addendum.
Data retention and security
We retain personal data only for as long as necessary for the purposes described in this Policy, to provide the services, and to meet legal, tax, accounting, and contractual requirements, after which we delete or de-identify it. We maintain appropriate technical and organisational measures designed to protect personal data against unauthorised access, loss, alteration, or disclosure, including encryption in transit and at rest, access controls, and monitoring. No system can be guaranteed to be completely secure.
Your rights and choices
Depending on where you live, you may have rights to access, correct, delete, port, or restrict the processing of your personal data, to object to certain processing, and to withdraw consent. If you are in California, you may have rights to know, delete, correct, and to opt out of any sale or sharing of personal data, and not to be discriminated against for exercising those rights.
To exercise your rights, contact us at privacy@quantisage.ai. We will verify your request and respond within the time required by applicable law. You may appeal a decision by replying to our response. If your data was submitted to the Platform by a business customer (so that we act as a processor), we will refer your request to that customer, who is responsible for responding.
Children
The Site and Platform are intended for business use and are not directed to children. We do not knowingly collect personal data from children. If you believe a child has provided us personal data, please contact us and we will delete it.
Changes to this Policy
We may update this Policy from time to time. We will post the updated version with a new “Last updated” date and, for material changes, provide additional notice through the Site or directly.
