Assessment

Consumer tiers (Free, Pro, Max): mediumCommercial tiers (API, Team, Enterprise): low

Reasoning: Consumer tiers do not use conversations for training unless the account setting is on, and deleted conversations are removed within 30 days; the exposure on consumer accounts is therefore the absence of a processor agreement and of stated storage location for an EU deployer, not training by default. Commercial tiers exclude training by default and are contracted under Anthropic's commercial terms. Exposure depends on the account tier in use.

Flags: GDPR Art. 28 (no processor agreement on consumer tiers) · GDPR Chapter V (storage location not stated for consumer tiers) · Assessed 2026-09-15. The assessment is Unseen's; the terms above are the vendor's.
