Why You Should Care About Anthropic's Privacy Practices

Anthropic collects sensitive conversation content and Inputs/Outputs that may be used for safety review or model training in flagged/opt‑in cases (data collection risk).
Sharing with affiliates, subprocessors, and international transfers can enable targeted marketing, profiling, or law‑enforcement disclosure (real‑world privacy impact).
The service is integrated into workflows and may hold payment and account data—risk to daily life if breached or misused (scale & influence).
Deletion and training‑dataset controls exist but are operationally complex; users should exercise rights and review the Privacy Center before sharing sensitive data.
