Data residency & data flow

Where data lives, and how it moves

Where your data is stored and processed, and how cross-border transfers are governed.

Primary region
Primary storage and processing of core customer data in the European Union (AWS eu-west-1, via Supabase).
Relocation
No setting relocates core customer data outside the EU.
Transfers
Cross-border transfers to sub-processors governed by SCCs (and the EU–US DPF where applicable).
AI model providers
The model providers behind Club AI (Anthropic, Google) are named in our sub-processor table with region and data terms, and each is bound by a DPA with SCCs. Prompts are processed under contract and never used to train or fine-tune their models. We list them so you always know which third parties touch AI-related data.
Authoritative list
The authoritative transfer list is the sub-processor table above and our Data Processing Agreement.
