Privacy Policy

Sensorist Ltd, a company registered in England and Wales (company no. 17526421), registered office Unit 13 Freeland Park, Wareham Road, Lytchett Matravers, Poole, England, BH16 6FA, trading as Sensorist AI, is the controller of personal data processed through the Service. For data protection enquiries, contact privacy@sensorist.ai.

When you use the Service we collect:

• Account information. When you sign in with Google or Microsoft we receive your name, email address and profile picture from your identity provider.
• Conversations. The questions you ask the Service and the answers it produces, together with any items you save to your library or projects.
• Usage data. Basic technical information including IP address, browser type, device, pages visited and timing of visits.
• Cookies. Authentication cookies necessary to keep you signed in, and a first-party analytics cookie that recognises a returning browser. Google Analytics cookies are set only if you accept them. We do not use third-party advertising cookies.

We use your information to:

• provide, maintain and improve the Service;
• authenticate you and protect your account;
• respond to your enquiries and provide support;
• understand how the Service is used so we can make it better;
• comply with legal obligations.

Model training: when you use the public preview or the Free plan, your conversations and uploads may be used to evaluate, improve and train the models that power Sensorist AI. Account identifiers are removed before any such use, and we make reasonable efforts to redact obvious personal data. On a paid Pro subscription, your conversations and uploads are never used to train AI models. Enterprise customers are governed by their separate agreement and this training provision does not apply to them.

We share information only as necessary to operate the Service:

• Identity providers. We rely on Google and Microsoft to authenticate you. They process the information needed to sign you in under their own privacy policies.
• Model providers. Your prompts are sent to the model provider that serves the answer (Azure OpenAI and Azure AI Foundry). We do not include your name, email or other personal account identifiers in prompts.
• Service infrastructure. We use cloud hosting, database and analytics providers acting on our instructions and bound by data processing agreements.
• Product analytics. We use our analytics provider, hosted in the EU, to understand how the Service is used: the pages you visit, the features and controls you use, and the materials you open. These events carry a pseudonymous identifier, never your name or email address. Page views are sent from your browser without cookies, so the provider receives your IP address but does not store it with the events. We rely on our legitimate interest in understanding and improving the Service; you can object by contacting us.
• Questions and answers. We share your questions and the answers, under a pseudonymous identifier, with our analytics provider (hosted in the EU) to improve the quality of answers. For Pro subscribers, they are never used to train AI models. We rely on our legitimate interest; you can object by contacting us.
• Legal. We may disclose information when required by law or to protect our rights, our users or the public.

We do not sell your personal information.

We keep account information for as long as you have an account. Conversations are retained to provide history within the Service and for the purposes described in section 3. You may delete individual conversations or your entire account at any time. After deletion, residual copies may persist in backups for a limited period before being overwritten.

Depending on your location you may have the right to access, correct, delete or export your personal information, to object to or restrict certain processing, to withdraw consent, and to lodge a complaint with a supervisory authority. To exercise these rights, contact privacy@sensorist.ai. We respond within thirty days.

Sensorist AI is operated from the United Kingdom. Data processing may take place in countries with different data protection laws. Where we transfer personal data outside the UK or the European Economic Area, we rely on appropriate safeguards such as Standard Contractual Clauses or adequacy decisions.

We use reasonable technical and organisational measures to protect personal information, including encrypted transport, access controls, regular review and the principle of least privilege. No system is perfectly secure, and we cannot guarantee absolute security.

For account security we record the time and IP address of each successful sign-in, and the IP address that started each conversation. These are used only to detect and investigate suspicious activity.

The Service is not directed at children under sixteen. We do not knowingly collect personal information from children. If you believe a child has provided us information, please contact us so we can delete it.

We may update this Privacy Policy from time to time. The “Last updated” date at the top of this page reflects the latest version. If a change is material we will make reasonable efforts to notify you.
