Chat privacy
Last updated 12 October 2026
What this covers
This page is about the chat assistant (Vupo) at chat.v2stack.com and the chat button on V2Stack sites. The tools themselves run in your browser and never upload your files. The privacy policy on v2stack.com covers the whole site.
What we collect
The messages you type, the anonymous chat ID your browser makes so a conversation can continue, the page you were on when you asked (its address and title), and any details you put in a problem report, such as an email address if you give one.
We do not ask for or need your name, address or passwords, and you should not type them.
Who sees it
Your messages go to V2Stack’s chat service and, so a reply can be written, to an AI model provider through OpenRouter. We ask the provider not to keep prompts or train on them.
Conversations and problem reports are stored in our database so the team can read reports and improve answers.
On your device
The conversation is also saved in your browser so it is there when you come back. “New chat” clears it and the anonymous ID.
Your choices
You can clear the chat at any time. To ask us to delete a stored conversation or report, contact us from v2stack.com/contact and include your anonymous chat ID or the report number.
Chat is not for children under 13; ask a parent first.
