Who is responsible for your data
Search Answer Optimisation is a trading name of Trilogy Research Limited ("Trilogy"), registered in England and Wales, company number 14632667. Registered office: 2 Bedford Mews, East Finchley, London N2 9DF.
Trilogy is the controller of your personal data. We are registered with the Information Commissioner's Office (registration number ZC228457).
This notice covers Trilogy and all its trading names, including Search Answer Optimisation.
Data we handle for our clients. When a client uses our services to handle personal data, such as calls answered by a voice agent we provide, the client is the controller and we act as their processor. We use that data only on the client's documented instructions, under a written contract that complies with UK data protection law, and we bind our own suppliers to the same obligations. Any transfer outside the UK is protected by safeguards recognised under UK law. This notice does not cover that data; the client's own privacy notice does. Please direct any questions or requests to the business you dealt with. If you contact us instead, we will forward your request to them promptly and assist them in responding.
Where we provide a service that runs entirely on equipment at a client's premises, any personal data involved remains on that equipment, under the client's control.
If you have any questions about this notice or how we use your personal data, please email privacy@trilogyresearch.co.uk. We can also provide this notice in another format, such as large print, on request.
What we collect and why
Whenever we ask for your details, sharing them is your choice, and we ask only for what we need. Without them, we would be unable to respond to you or to work with you.
If you contact us or sign up. We use the details you provide to handle your enquiry or request (our legitimate interests). If you opt in, we may send you updates about our services that we believe are valuable and relevant to you, by the channels you choose (your consent).
If we contact you first. We approach people at select businesses, using contact details and information about your role and business from public sources, such as company websites and news, or from a referral. We may use these to send you up to two emails about our services that we believe are relevant to your business (our legitimate interests).
If you become a client. We use your details to deliver our services and invoice you (our contract with you), and to keep our accounts (our legal obligations).
If you engage with our AI agents. They may answer when you call us, and call you if you have opted in to calls (your consent). They always tell you that they are AI. We may record these conversations to handle your enquiry and improve our services (our legitimate interests).
We never sell your data or use it to train AI models. Any decision with a legal or similarly significant effect on you is made by a person, never by automated means alone.
Who we share your data with
We share your data, as needed, with service providers that process it on our behalf, under contract, for client record management, email, website hosting, payments, email verification, research, and AI and telephony services. Our payment provider also uses some payment data for its own purposes, such as fraud prevention. Where the law requires, we may also disclose data to public authorities.
Where a provider is based outside the UK, mainly in the United States, your data is protected by UK adequacy regulations, including the UK–US data bridge, or by the UK's approved data transfer agreements. You can ask us for a copy of these safeguards.
How long we keep your data
We keep personal data only as long as we need it. If we contact you first, we keep your details for 12 months after our last email, unless a conversation follows. Enquiries and conversations are kept for 24 months after our last contact, and client records for six years after our work together ends, for tax and legal purposes. Recordings and transcripts of conversations with our AI agents are kept for 90 days, or longer only if needed to resolve a concern. A record of your consent is kept for 24 months after we stop relying on it. If you ask us not to contact you, we keep only your contact details and the date, indefinitely, so your request is always respected.
Your rights
You can ask for a free copy of your data, and ask us to correct it, delete it or limit how we use it. You can also object to how we use it and, where this right applies, ask us to transfer it to you or another organisation. Email privacy@trilogyresearch.co.uk and we will reply within one month. To protect your data, we may first ask you to confirm your identity.
You can stop our updates and emails about our services at any time, and withdraw any consent you have given: use the unsubscribe link in any of our emails, reply "stop", or contact us. Unsubscribe links take effect immediately, and other requests within one working day. Your choice applies to Trilogy and all its trading names.
