Shyeld

See what your browser extensions can read in your email, files, and AI chats. Runs entirely on your device.

Shyeld shows you which of your browser extensions can read your email, your files and docs, and your AI chats, and tells you when that changes. Many extensions ask for access to "all websites". That quietly includes your webmail, your cloud documents, and your conversations with AI assistants. Shyeld turns each extension's permissions into plain English so you can decide what to keep. WHAT IT DOES • Checks every extension installed in this browser and explains what each one can do, in plain English. • Flags extensions that can read your webmail, your files and documents, or your AI chats. • Gives each extension a High, Medium or Low risk level with a short reason, highest risk first. Extensions you've turned off are listed separately. • Alerts you when a new extension is installed, when an extension gains new permissions, or when a turned-off extension is turned back on. • Opens an extension's settings in one click, or turns it off after you confirm. PRIVATE BY DESIGN • Everything runs on your device. Shyeld makes no network requests: no account, no analytics, no servers. • It has no access to any website. It only reads your list of installed extensions and their permissions. • It keeps a small snapshot and your alert history on your device so it can spot changes. You can delete it anytime from the dashboard. GOOD TO KNOW • This version checks browser extensions only. Checks for connected apps and AI assistants are planned. • Risk levels are guidance based on permissions, not a malware scan.
