Sub-processors

Last updated: August 15, 2026

A sub-processor is a third party that processes customer data on our behalf so that Vyneron can work. This page lists every one of them, what each is used for, and what data reaches it. We keep the list to what the product actually needs, and we update this page whenever a vendor is added or removed. How we handle your data in general is covered in the privacy policy.

AI providers

Vyneron does not train, host or fine-tune any model. A request is sent to the provider, the answer comes back, and that is the extent of it. We do not send customer data for model training and we do not turn on any provider option that would allow it.

Sub-processor	Used for	Data involved	Processing location
Google LLC — Gemini API	Primary model for understanding requests, and for reading text from images	The message the customer sent, plus the workspace context needed to answer it	Determined by the provider

AI providers used only with your own key

Customers on paid plans can supply their own provider key. When they do, the request goes to that customer's own account with the provider, under their own agreement. Vyneron stores the key encrypted and nothing else changes.
