What changed
2026-10-15 — Correction: Claude zero data retention (v0.4)
Claude Enterprise and Claude Team ZDR cells corrected. Per Anthropic’s Privacy Center, ZDR applies only to eligible APIs, products using a Commercial API key (including Claude Code via the API), and Claude Code on Enterprise plans, not to the Claude chat app. The earlier Enterprise cell wrongly implied chat-app eligibility.
2026-10-15 — Pre-launch verification (v0.3)
Opened every source page directly. ChatGPT Enterprise residency confirmed as 10 storage regions (help article updated; earlier discrepancy resolved) plus inference residency in EU/US/UAE. ChatGPT ISO 27001 re-sourced to OpenAI security page (Business out of scope). Claude encryption cells reset to Unknown (only source was a consumer page). Claude Team and Glean default-retention cells reset to Unknown (no default documented). Perplexity and Microsoft Service Trust Portal cells marked Unverified (pages blocked automated access).
2026-10-15 — Gap fill & fact-check (v0.2)
Added Sana; filled SCIM, CMK, residency, pricing, certifications. Corrections: ChatGPT Business “audit” (no Compliance API on Business); Gemini “CMK” reclassified as client-side encryption (partial); Glean residency re-sourced to official deployment docs; ChatGPT Enterprise residency notes a discrepancy between pricing page and help article.
2026-10-15 — Initial draft
First snapshot of 8 plans across 7 vendors, from official vendor privacy, trust and help pages. Future entries will record each vendor term change with old value, new value and source.
