# Third Party Subprocessors

*Last updated: March 2026*

Tern Circular Ltd uses third-party subprocessors in order to provide our services. Core subprocessors are those that we can't offer our service without. Additional subprocessors might apply if additional services are used. Tern Circular Ltd engages these third-party subprocessors in accordance with our [Data Processing Agreement](/v1/legal/privacy-policy-merchants/data-processing-agreement.md). Merchants will be notified of any changes to this list in accordance with our Data Processing Agreement.

**Data residency note:** Our primary application hosting and data storage are configured to operate from the United Kingdom (London region) at the time of writing. However, some third parties may process or route data internationally (for example, via global network delivery, email routing, analytics processing, logistics providers, payment networks, or support operations). The table below summarises primary processing locations and where processing/transfers may occur.
