Overview

Clearmark runs a background check on every website you visit. See trust scores, country bans, ownership risks, and hidden red flags.

You wouldn't hire someone without a background check. Why trust a website without one? Clearmark automatically checks the background of every website you visit — revealing government ties, country bans, regulatory actions, and what companies don't want you to know. Visit kaspersky.com? Clearmark shows it's headquartered in Russia, subject to SORM surveillance law, and banned by the US Department of Commerce. Visit signal.org? Green light — open-source, audited encryption, clean record. A color-coded icon in your toolbar tells you everything at a glance. Green means clear. Red means risk. Click for the full report with sources. ★ HOW IT WORKS 1. Install — one click, no account required 2. Browse — Clearmark quietly checks each site in the background 3. See the score — a color-coded icon appears instantly Click the icon for a quick summary with risk flags and dimension bars. Open the side panel for a full nutrition-label report with entity details and source links. ★ WHAT IT CHECKS • Jurisdiction — where the company is based and what surveillance laws apply • Regulatory — government bans, sanctions, and trade restrictions • Terms & Privacy — how fair the terms of service and privacy policy are • Security — HTTPS, certificate maturity, and threat database status Every finding links to a verifiable source. No opinions. No speculation. Just facts. ★ PRIVACY BY DESIGN Clearmark uses hash-prefix lookups (k-anonymity) — the same technique as Google Safe Browsing. Our servers never see which sites you visit. No browsing history collected. No personal data. No tracking. https://clearmark.dev/privacy.html ★ PERMISSIONS • activeTab — reads only the domain (not page content) • storage — caches scores locally • alarms — refreshes cached data • sidePanel — displays the full report No access to browsing history, passwords, or form data.
