Kaomoji App only receives and stores the name of your Slack team and an anonymous identification token, which is used to connect you to your saved shortcuts. In order to improve the user experience, Kaomoji App also requests permission to post messages as you. Kaomoji App will never post as you without a clear indication that you wish to send a message, and you will always see the kaomoji that is about to be posted.
Kaomoji App is an open source project.
If you have any questions/concerns/suggestions, please submit an issue, or email the Kaomoji App team.
