We do not sell personal data. We may share personal data with trusted service providers where necessary:

7. Analytics and Advertising Measurement
Analytics. Where you accept optional cookies, we use PostHog (hosted in the European Union), Microsoft Clarity and Google Analytics to understand how visitors use the Website. These may collect pages viewed, how you arrived at the Website, session duration, interactions with pages, device and browser information, and approximate location. PostHog is configured so that it does not record clicks, keystrokes or the contents of forms, and does not build profiles of individual visitors.
Advertising measurement. We advertise on third-party platforms. Where you accept optional cookies, the Meta Pixel, the TikTok Pixel, Google Ads conversion tracking, the Taboola Pixel and a visitor-identification service (Leadpipe) run on the Website so that we can measure which adverts lead to visits and orders and show our adverts to relevant audiences. The platforms may also use this information for their own purposes under their own privacy policies.
Information sent from our servers. Separately from cookies, when you place an order we send details of the purchase (such as the order reference, value and products) to Meta, TikTok and Google so that they can match it to an advertisement you may have seen and so that we can measure our advertising. To allow matching, this may include your email address, telephone number, IP address and browser type. This is done when an order is placed and does not depend on cookies. You can object to it at any time by contacting us at info@merciaresearch.com.
You can control optional cookies and similar technologies using Cookie settings in the footer of the Website. See our Cookie Policy for details.
8. Data Retention
- Order records: 6 years from the date of the order, to meet UK accounting/HMRC requirements.
- Contact-form messages: 24 months from receipt, then deleted.
- Newsletter subscriptions: until you unsubscribe.
- Server logs: 30 days for security-monitoring purposes.
9. Data Security
We implement reasonable technical and organisational measures designed to protect personal data against unauthorised access, disclosure, loss, misuse, alteration, or destruction. Despite our efforts, no system is completely secure; please notify us immediately at info@merciaresearch.com if you suspect a breach.

Where personal data is transferred internationally, we will take appropriate measures designed to ensure an adequate level of protection in accordance with applicable data protection laws.
13. Cookies
We use strictly necessary cookies and browser storage to run the Website: a secure session cookie when you sign in to your customer account (or, for our team, the admin area), and browser storage that keeps your shopping cart, your age and terms confirmation, and your cookie choice.
