SpamTrace 作者： Ethan+

SpamTrace helps you find out who sold your email.

When you sign up for a website, SpamTrace automatically fills in a tagged version of your email (e.g., you+facebook@gmail.com). Later, when spam arrives, you can see exactly which company shared your data by checking the "To" address.

Features:
• Automatic email tagging on signup forms
• Works on all websites, including dynamic forms (React, Vue, etc.)
• Local history of tagged emails
• 100% private — no data ever leaves your browser
• No account required

How it works:
1. Enter your base email in the extension popup
2. Browse and sign up for sites normally
3. When spam arrives, the +tag reveals the source

SpamTrace uses only local storage. There is no server, no analytics, and no tracking.
