Important Disclaimer
SlashClean Browser Extension is not affiliated with, endorsed by, or connected to Slack Technologies, Inc. Slack is a trademark of Slack Technologies, Inc. This extension is an independent third-party tool.
Privacy First Approach
The SlashClean Browser Extension is designed with privacy as a core principle. The extension runs entirely locally in your browser and does not collect, transmit, or store any of your Slack data outside of your own browser.
1. How the Extension Works
The SlashClean Browser Extension operates entirely within your browser environment:
- Local Operation: All extension functionality runs locally in your browser
- Session-Based Access: Uses your existing Slack session tokens only within your browser to authenticate requests to Slack's servers
- No External Servers: The extension does not communicate with SlashClean servers or any third-party servers for Slack data processing
- Direct API Calls: All Slack API requests are made directly from your browser to Slack's official API endpoints
2. Token Handling and Authentication
Token Security
The extension uses your existing Slack session tokens only within your browser to authenticate requests to Slack's servers. These tokens are never transmitted to SlashClean or any third-party servers, and never leave your browser.
- • Tokens remain in your browser's secure environment
- • No token extraction or external transmission
- • Uses standard browser security mechanisms
- • Tokens are managed by your existing Slack session
3. Data Collection and Usage
What We DO NOT Collect
The extension does not collect, access, store, or transmit:
- • Your Slack messages or message content
- • Your Slack workspace data
- • Your Slack authentication tokens or credentials
- • Your personal information from Slack
- • Any files, images, or attachments from your Slack workspace
- • Browsing history or activity outside of the extension
- • Any data from your computer or browser beyond what's necessary for basic extension functionality
License Verification Only
The only external communication performed by the extension is license verification with Gumroad:
- • Purpose: To verify that you have a valid license to use the extension
- • Data Transmitted: Only your license key (provided by you after purchase)
- • No Slack Data: No Slack messages, tokens, or workspace data is ever transmitted during license verification
- • Secure Connection: License verification uses HTTPS encryption
- • Functionality Limitation: If a valid license key is not provided, the extension will not perform bulk deletion actions. No Slack data is accessible outside of this limitation.
4. Chrome Extension Permissions
The extension requests the following permissions to function:

5. Data Storage and Security
Local Storage Only
The extension stores minimal data locally in your browser:
- • License Key: Your Gumroad license key for activation
- • Settings: Your extension preferences and configuration
- • No Slack Data: No messages, workspace data, or personal information is stored
All stored data remains local to your browser and is never transmitted to external servers.
6. Third-Party Services
