LinkedGuard

Flag recruiter spam, crypto scams, cold pitches and phishing in your LinkedIn inbox. 100% local, no tracking.

LinkedGuard highlights unsolicited messages in your LinkedIn inbox so you can ignore them at a glance — no more wasted time on recruiter copy-paste, crypto scams, MLM pitches, or "quick 15-min call" cold outreach. When someone sends you a first message containing a word from any enabled category, LinkedGuard highlights the sender's name in red directly in your conversation list, adds a small ⚠ badge with a tooltip showing which list and which keyword triggered the flag, and outlines the sender's avatar in red. Nothing is archived, deleted, or rewritten. You stay in control. 14 built-in categories: Recruitment Spam, Crypto & Financial Scams, MLM / Network Marketing, AI & Prospection Pitches, Marketing Agency Pitches, SEO & Backlinks, Coaching & Mentorship Pitches, Course & Training Sales, Outsourcing & Offshore Dev, SaaS Cold Outreach, Phishing & Account Threats, Investment Opportunities, Generic Spam (disabled by default), and Romance / Bot Greetings (disabled by default). Around 180 keywords ship by default. You can toggle any list, edit its keywords, or create your own custom lists from the options page. LinkedGuard runs entirely in your browser. Nothing ever leaves your device: no analytics, no telemetry, no remote logging, no requests to any server outside linkedin.com. Settings are stored only in your browser's local storage (with optional Firefox Sync). The activity log keeps the last 50 events, locally only. Permissions used: storage to save your enabled lists, custom keywords, and activity log locally; tabs to open the options page on the right tab when you click "Settings" or "Activity log" in the popup; https://www.linkedin.com/* because that is the only site this extension is allowed to read or modify. Source code, full keyword lists, and changelog are available at https://github.com/Sn0wAlice/LinkedGuard. Licensed under MIT. Roadmap: auto-archive (currently labeled "soon" in the UI, being stabilized for LinkedIn's new shadow-DOM messaging), per-language pre-built lists (FR, ES, DE), right-click "Add sender to allow-list", and optional regex mode.
