Zolt AI
Subprocessors
Updated September 30, 2026
These are the outside services that process data on our behalf to run Zolt, what each one does, and what it receives. We send each only what the feature you are using needs. Your content is never used to train AI models — ours or our providers' — and it's never sold. How we handle your data overall is in our Privacy Policy.
