Before you conclude anything
This only means we couldn’t read it on a public page. HiddenLayer 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 HiddenLayer. 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.
