Own Message Cleaner for Slack

Delete your own messages from the currently open Slack Web conversation.

Delete your own Slack messages in bulk, safely. • Clean the open chat: a number of messages, all of them, or a single month. • Clean several chats at once from a list with your message counts. • View and back up: see your messages before deleting, uncheck the ones to keep, and download a CSV backup. • Simulation mode: run everything without deleting anything, to see what would happen. • Automatic cleanup: every hour, day or week, keeping the recent messages you choose. • Optional: remove files you uploaded and emoji reactions you added. • Protected chats are never touched. • Activity charts, cleanup history and an optional weekly summary. • English and Spanish. Everything runs in your browser. The extension only talks to Slack: no servers, no analytics, no account. Not affiliated with Slack Technologies, Salesforce, or Google.
