Let's keep it simple.
When you connect your GetSpeedBack account with your Slack account, we retain your slack user id in order to send you periodic messages.
When you disconnect your Slack account from your GetSpeedBack account, we remove all of your Slack data from our database.
We do not store any personal information from your Slack integration.
Please contact us at hello@getspeedback.com for any specific questions around data collection.
