We only extract and save the following info on all your team members. 


- Slack user id  - to be able to communicate with you on a direct message

- Timezone - to ensure we never ping you on odd hours

- Email - to create profile pages (feature that is coming soon)

- Name cause don't we need to be on a first name basis :)


This info is available on Slack's UserInfo API we consume, once we are in your public channel.
