SmartFill Shield

SmartFill Shield is a security-focused autofill extension for Chromium browsers. What it does - Fill saved profile fields only on domains you (or your admin) add to a trusted allowlist - Check the page against domain rules and phishing heuristics before autofill UI and Fill - Keep profile field values encrypted locally (AES-256-GCM) in extension storage — no SmartFill cloud sync of form PII What it is not - Not a general password manager - Not an ad blocker or browsing-analytics tool - Not remote-code / CDN-script based — logic ships inside the extension package Getting started 1. Open Options → Domains and add a trusted site (or use the popup quick-add) 2. Create a profile under Options → Profiles 3. On a trusted page, use the overlay Fill control when you want to autofill Privacy See the Privacy Policy URL on the listing. Export and delete your data anytime from Options → Profiles → Data management (or uninstall the extension). Clearing ordinary website data in browser settings does not remove extension storage.
