Privacy Policy

Last updated: 20 October 2026

Sebastian (“Sebastian”, “we”, “us”, “our”) respects your privacy. This policy explains what personal data we collect, how we use and share it, and the choices and rights you have. It is written for the people who visit our website, ask us for a demo, correspond with us, or use Sebastian through their employer.

Sebastian is financial intelligence software for finance teams. It connects to a company’s accounting, planning and operating systems to maintain a current financial outlook, draft accounting work for review, and keep every figure tied to its source. Sebastian is headquartered in the United States.

1. Who this policy covers

This policy applies where Sebastian decides why and how personal data is processed, which the law calls being a “controller”. That includes our website at getsebastian.ai, demo requests and other enquiries, marketing, events, recruiting, and the account and usage information we hold about the people who use our services.

It does not apply to the financial records, documents, transactions and other content that our customers connect to or upload into Sebastian (“Customer Data”). Customer Data can include personal data about a customer’s employees, suppliers and customers. We process Customer Data only on our customer’s instructions and under the agreement we have with that customer, including its data processing terms. For Customer Data, our customer is the controller. If you have a question about personal data held in a customer’s Sebastian workspace, please contact that customer.

Information we collect automatically

Information from other sources

3. How we use personal data

We use personal data to:

We do not use Customer Data to train models that are shared across customers, and we do not use personal data for automated decisions that have legal or similarly significant effects on you.

We may aggregate or de-identify data so that it no longer identifies anyone, and use that data to study and improve the service, for research, and in published statistics. We do not try to re-identify such data.

4. Who we share personal data with

We do not sell personal data.

5. How we keep personal data secure

We protect personal data with technical and organisational measures designed to match the sensitivity of the data, including encryption in transit and at rest, access controls and least-privilege access for our staff, logging and monitoring, and regular review of our suppliers. No system is perfectly secure, so we also maintain incident response procedures and will notify affected customers and individuals where the law requires it.

6. International data transfers

We are based in the United States and our service providers operate in the United States and other countries. When personal data from the European Economic Area, the United Kingdom or Switzerland is transferred to a country without an adequacy decision, we rely on appropriate safeguards such as the European Commission’s Standard Contractual Clauses and the UK Addendum, together with additional measures where needed. You can ask us for more information about these safeguards using the contact details below.

7. How long we keep personal data

We keep personal data only as long as we need it for the purposes in this policy. In general: demo requests and enquiries for up to two years after our last contact; account and usage information for the life of the customer relationship and a limited period after it ends, as set out in the customer agreement; records we must keep for tax, accounting, audit or legal reasons for as long as those obligations last; and recruiting information for up to one year after a decision unless you ask us to keep it longer. When data is no longer needed we delete or anonymise it, or, where that is not immediately possible, isolate it until deletion is possible.
