Flann is a WhatsApp campaign product operated by MSTRMND. For privacy questions, contact us at info@mstrmnd.co.uk.
About you. What you give us when you sign up or submit a lead form: business name, contact name, WhatsApp number and email.
About your customers. The contact records you import or create — names, phone numbers, tags and notes — and, if you run a loyalty program through Flann, their visit and spend history.
Messages. The content of messages sent and received through your connected number, including any photos, voice notes and files your customers send, so the conversation can be shown back to you and the assistant can answer in context.
Operating the service. Delivery and read status, approval decisions, and basic technical logs needed to run and secure the product.
To provide the dashboard, send campaigns you approve, verify your number, and support your account. We do not sell personal data.
If you are in the UK or EU you may request access, correction, deletion, or portability of your data, and object to processing. Contact info@mstrmnd.co.uk to exercise these rights.
Flann relies on third parties to run the service. They fall into four categories: cloud hosting and database providers; the messaging gateway that connects your number to WhatsApp and other channels; AI providers that draft message text; and, where you use one, your loyalty platform. Each processes data only on our instructions.
A current, named list of processors is available from info@mstrmnd.co.uk on request.
We keep data only as long as needed to run the service or as required by law. WhatsApp conversation history is retained for the life of the account so the assistant can remember a customer and the business can see what was said; you can ask us to delete it at any time. Questions: info@mstrmnd.co.uk.
