Privacy & Support

By adding to your Slack team, you acknowledge we do not have control over what your Slack team users send to the /kaomoji slash command and you agree to the privacy policy information on this page. is an automated service that retreives content from a very large dataset using an imperfect search algorithm.

If you have any concerns or questions about the service please get in touch at support [at]

Data collection and storage aims to collect only the bare minimum amount of data required for the operation and improvement of the service it provides. We do not collect personally identifiable information such as email addresses, usernames, or real names. The following data is provided to us via the Slack API and is stored encrypted at rest within AWS and encrypted in transit with SSL:

  • Slack user ID (e.g. U1565971)
  • Slack team ID (e.g. T1765501)
  • Slack team name (e.g. The Fort)

In addition to the Slack API provided data, we also store and analyse the following to improve the service that provides:

  • Which feedback button was clicked
  • The text sent with the /kaomoji slash command after clicking a feedback button

This website uses Google Analytics to gain an insight into how users are finding and to understand how users are interacting with the site.

Data Usage

Team and user ID

The Slack team and user ID information that was provided to us via the Slack API upon installation is used to verify that commands sent from your Slack team are genuine and the app has been installed correctly for each member of your team.

Team names

We may use Slack team names on marketing materials for our own site or associated social media accounts. Permission to use this information will be acquired before any materials are generated.

Slash command text

Text sent to the /kaomoji command is collected through the Segment analytics API only when the feedback prompts are clicked or when a kaomoji is not found. This data is then analysed with the Mixpanel analytics service so we can gain a better understanding of what the user was attempting to send. The result of the analysis is then fed back into the search algorithm to improve subsequent searches for other users of the service.

Feedback buttons

When clicking on any feedback buttons sent by the app user, the app will send the text of the original message, the kaomoji it retreived, and the feedback label that was clicked.

We will never share or sell any data we collect with a 3rd party unless required by law to do so.

Slack app permissions

The Slack API allows us to request access to certain actions or data with your Slack team. The following is required for the operation of the Slack App.


This is a simple one, it allows us to add the /kaomoji commands to your team!


This permission allows us to send a message on behalf of a user after they've executed a /kaomoji command. While this might sound a bit scary, we only use this to improve the flow of a conversation by sending kaomojis as if they were typed by the user themselves. We never use this permission to send messages without the user first requesting us to do so via the /kaomoji slash command.

For more information about how Slack handles permissions, please see their documentation on Scopes and permissions.
