Mejesi respects your privacy. Data collected via WhatsApp (your phone number, questions, and answers) is used solely to operate the service and is never sold to third parties.
To understand you better, Mejesi can keep a short note of things you tell it (like the town you live in or what you do) and of what you do here (the jobs you look for, your shop). It is used only as background when we work out what you mean; it is never shown to anyone else and never includes health, faith, politics, money trouble or contact details. You can see it, delete any of it or switch it off in WhatsApp: More, then What I remember (or type "forget everything").
