Controller and scope
Grupo ZGH SpA, Chilean tax ID 76.780.278-9, Chile, is the data controller for Z-Messenger, our internal enquiry management tool. This policy applies to conversations with Grupo ZGH on Facebook Messenger and with @zghcl on Instagram Direct.
Data we process
We process the text of your messages and our replies, account, conversation and message identifiers, timestamps, and profile information Meta makes available, such as your name and username. We also record conversation assignments, internal notes and the staff member who replies.
Multimedia content in these channels is flagged for viewing in Meta Business Suite; the current integration does not download these files into Z-Messenger.
If you ask us to register an enquiry, we may request your first name, last name and email address. A staff member records those details and a summary in our Public Contact system. This does not automatically link you to a customer account or send an email. Do not send passwords or access codes through these channels.
Purposes
We use this data to answer your enquiries, coordinate our staff, maintain continuity in conversations and keep a record of replies. The integration handles conversations people initiate with Grupo ZGH; we do not use this permission to start campaigns or contact people who have not messaged us.
Access and infrastructure
Z-Messenger runs on infrastructure owned by Grupo ZGH. Access to messages and backups is restricted to authorised ZGH staff. We do not give external companies access to operate the system or process conversations on our behalf.
Communication through Facebook and Instagram uses Meta services and APIs and is also subject to those platforms’ policies.
Conversation retention
Conversation history does not expire automatically because of its age. We retain it for as long as needed for the legitimate business purposes described, including continuity of service.
We handle valid deletion requests from individuals and applicable requests from Meta. We delete or anonymise data where appropriate and when it is no longer needed. If a legal obligation requires us to retain information, we limit retention to that requirement and explain it in our response where permitted.
Questions and requests
Email info@mail.zgh.cl to ask about your data, request a correction or ask for deletion. Our deletion instructions explain how to identify your conversation and how we verify your request.
