Data retention

When you connect a Slack channel to Plain, we store certain information from that channel to power seamless support workflows. This lets your team manage Slack-based support with full visibility, accountability, and context from within Plain.

You’re always in control

Plain only stores data from Slack channels where the bot has been explicitly added. If you don’t invite Plain to a channel, we don’t see or store anything from it.

This means you decide what gets ingested – and what doesn’t.

What we store (and why)

Once the Plain bot is added to a Slack channel, we securely store the following data:

• Message content
  So you can read and respond to support requests directly from Plain.

• Message metadata
  Includes timestamps, message IDs, and emoji reactions – useful for tracking and triggering automations.

• Channel members
  So you can @mention teammates and attribute messages to the correct authors.

• Channel metadata
  Such as the channel name, ID, and associated teams – helps with organization and routing.

What we don’t keep

If we receive any additional data from Slack’s APIs that’s not needed for Plain to operate, we automatically delete it after 7 days.

This 7-day retention window is solely for operational recovery (e.g. restoring data during an incident). After that, it’s gone.

What happens when messages are deleted in Slack

If a message is deleted in Slack:

• Plain deletes the message content.

• We retain a minimal audit trail – including that a message existed and who sent it.

This keeps your support history accurate for compliance and accountability, while respecting your customer’s data preferences.

Plain is designed for modern B2B support teams handling sensitive conversations. Our Slack integration gives you:

• Granular control over what’s ingested

• Minimal retention of unnecessary data

• Full audit trails for deleted messages

So you can confidently support customers in Slack – without compromising visibility or trust.
