Consider the following scenario. Company A develops a Slackbot for use in the Slack workspace of Company B by person C. Person C communicates with the chatbot of company A. Company A wants to ensure anonymity and privacy of these messages.
I read that Slack Plus enables "compliance exports" of all direct messages, which are supposedly private. I could not find a reference about a slackbot.
Who can read the messages between the Slackbot of Company A and Person C: Company B? Slack itself?
NOTE: My question was higher-level than SSL and IP addresses. It concerns whether Slack's terms of service give access to direct communication between users and chatbots to paying companies or Slack admins.
