LeadOven for WhatsApp Web signs in with your LeadOven console email and password and keeps only the resulting session token in the browser's extension storage. For the chat that is open on web.whatsapp.com it reads the contact's WhatsApp number and saved name — never the messages — and sends them only to the LeadOven server you signed into (app.leadovenai.com), to find or create that contact's lead. It sends nothing to anyone else, reads nothing on any other site, and stops when you sign out or remove it. Full policy: https://leadovenai.com/privacy (LeadOven Labs LLP).
