5. FullStack MCP: specific data flows
FullStack MCP is a service that connects the artificial intelligence assistant chosen by the customer ("third-party AI": for example Claude by Anthropic, or Cursor) to Theme FullStack Ltd's documentation and processing tools. Its operation involves the following data flows:
- No access to your Shopify store. The FullStack MCP server never connects to your store and holds no credentials or access token relating to it. Operations on your store are carried out by you, from your machine, via the official Shopify tool (Shopify CLI).
- Volatile file processing. The theme configuration files that your third-party AI sends to the server (for validation, audit or migration) are processed on the fly and then immediately discarded: they are neither retained nor used for any other purpose — in particular not for training artificial intelligence models. Usage logs do not contain the content of these files. We recommend that you do not include personal data in the theme files you submit.
- Transit through your third-party AI. Your instructions and files pass through the third-party AI you have chosen, within the framework of the contract between you and its provider (for example Anthropic) and in accordance with that provider's privacy policy. Theme FullStack Ltd is neither the controller nor the processor of the processing carried out by your AI provider, over which it has no control. We invite you to read your AI provider's privacy policy.
- Sessions and devices. Access to FullStack MCP is authenticated via your FullStack Hub account (OAuth). You can view and revoke connected sessions and devices at any time from FullStack Hub.
6. Hosting
- The website themefullstack.com is hosted by Webflow, Inc. (398 11th Street, 2nd Floor, San Francisco, CA 94103, USA).
- The FullStack Hub platform (app.themefullstack.com) is hosted by Vercel Inc. (USA) and Supabase (database).
- The FullStack MCP server (mcp.themefullstack.com) is hosted by Vercel Inc. (USA), with a Supabase database.
7. Transfers of data outside the European Union
Some providers (in particular Stripe, Vercel, Webflow, Google, Meta) are located outside the European Union or may transfer certain data there. In such cases, Theme FullStack Ltd ensures that these transfers are governed in accordance with the applicable regulations, in particular on the basis of an adequacy decision of the European Commission (for example the EU-US Data Privacy Framework) or appropriate safeguards such as Standard Contractual Clauses (SCCs).
8. Retention periods
Data is kept for as long as necessary for the purposes pursued, then deleted or anonymised. The periods applied, aligned with the longest legal obligations where they exist, are as follows:
- Billing, accounting and tax data: 10 years, in accordance with Maltese legal obligations to keep accounting records (the legal period prevails over any other).
- Account, licence and support data: for the duration of the contractual relationship, then until the expiry of the applicable limitation period (for evidentiary purposes), unless a longer legal retention obligation applies.
- Data of prospects and persons without an active contractual relationship: up to 3 years from the last contact.
- FullStack MCP usage logs: 12 months, then deleted or aggregated into anonymous statistics.
- Sessions and devices connected to FullStack MCP (OAuth): for the duration of the session's validity, and at the latest until revoked from FullStack Hub.
- Files processed by FullStack MCP: not retained (on-the-fly processing only).
- Data from consent-based trackers: in accordance with the settings of the relevant tool and your choices, not exceeding the periods recommended by the competent authorities.
9. Security
Theme FullStack Ltd implements appropriate technical and organisational measures to protect personal data against loss, unauthorised access, disclosure or alteration. Payment data is processed exclusively by Stripe, PCI-DSS Level 1 certified, and is never stored by Theme FullStack Ltd.
