This is a public service announcement.

If your job uses Slack, please remember that the administrators that have been configured can view any channel and download all files and all information published, including channels that are "private" or between 2 individuals.

Your discussions are not secure and can be snooped upon, even private conversations.

In other words: there is no privacy on Slack. Period.

This is the end of this public service

(Don't ask how I know that)


@ParadeGrotesque hi, is that the same with mattermost ?

@lm Nope. Slack is the "commercial" version, so to speak, and Mattermost is the open source "copy" of Slack.

@ParadeGrotesque yes, I know that, but nothing is secured either on mattermost so the admin could see everything, no ?
