Sema4.ai DPA
Sema4.ai's data processing agreement gives 30 days to object to a new sub-processor. Here is the clause, from our September 24, 2026 copy:
30
days to object
“3.5 Right to Object – Company may object in writing to Sema4.ai ’s appointment of a new Sub-Processor on reasonable grounds relating to data protection by notifying Sema4.ai in writing within thirty (30) calendar days of receipt of notice in accordance with Section 3.4 .”

Before you conclude anything
This only means we couldn’t read it on a public page. Sema4.ai may share it in its agreement, a trust portal, or with any customer who asks.
So treat it as a question to ask them: “Can you send your sub-processor list, and tell us when it changes?”
What this page doesn’t tell you
No score.
Nothing here rates Sema4.ai. A short notice window is a contract term, not a criticism.
Public pages only.
Private notices and negotiated terms are invisible to us. Your agreement may say something different.
Wrong? Tell us.
Corrections are free, always. We reply within 2–3 business days.
