Frequently Asked Questions
Can PhishArmor read my emails?
PhishArmor only extracts specific signals from emails you choose to scan: links, sender info, and text patterns. We never store full email bodies, and all data is processed securely. You are always in control of what gets scanned.
How does webpage scanning work?
Click the PhishArmor icon in your browser toolbar and hit "Scan This Page" for a deep AI analysis. PhishArmor checks the page's domain, forms, links, and content for phishing indicators like fake login forms, lookalike domains, and credential harvesting.
What is the always-on safety indicator?
PhishArmor automatically checks every website you visit for common phishing signals like lookalike domains, suspicious TLDs, and missing HTTPS. If something looks off, the extension icon shows a yellow or red warning badge. This runs locally in your browser with no API calls and does not count toward your scan limit.
Which email providers are supported?
Gmail, Yahoo Mail, and Outlook (both outlook.live.com and outlook.office.com). Webpage scanning and the safety indicator work on any website.
Which browsers are supported?
Chrome, Firefox, Edge, and Opera. The extension works on any Chromium-based browser.
How accurate is the scam score?
PhishArmor uses advanced AI that analyzes multiple signals simultaneously: link analysis, form detection, language patterns, sender verification, and more. Our accuracy improves continuously through user feedback.
What happens when I use all my free scans?
Your scan count resets at the beginning of each month. Both email and webpage scans count toward your limit. Upgrade to Premium for unlimited scans.
Can I cancel Premium anytime?
Yes. Cancel anytime from your account. You'll keep Premium access until the end of your billing period.
