Extension Metadata

About this extension
Most Slack users don't know this: if your company uses Business+ or Enterprise, your boss can export and read every DM you've ever sent. Without telling you.

SlackGuard shows a colour-coded banner inside Slack the moment you open it:

🔴 HIGH RISK — Your plan allows full DM export by admins right now
🟡 MEDIUM RISK — Exports possible under certain circumstances
🟢 LOW RISK — Limited export capabilities, you're relatively protected

⌨️ STEALTH MODE: Press Alt+Shift+H (Mac: Cmd+Shift+H) to instantly hide the banner during screen shares.

PRIVACY FIRST
SlackGuard reads no message content whatsoever. It only checks your workspace plan type the same info Slack already loads in your browser. Nothing leaves your device. No account needed. No tracking.

Free to install. Core privacy features always free.
