Canary Trap от Leshya Bracaglia

CanaryTrap gives every website you sign up for its own unique, trackable email alias (yourname+sitename@gmail.com) so if your inbox starts getting spam, you can trace it back to exactly which company leaked, sold, or got breached with your address.

How it works:
• Focus any email field on any site and CanaryTrap suggests a per-site alias built from your base email.
• Choose "Show fill button" to confirm before filling, or "Auto-fill silently" to skip the prompt.
• Right-click an email field to copy the alias to your clipboard instead of filling it.
• The popup keeps a log of every site you've used an alias on, with use counts and last-used dates, so you can see at a glance which one is leaking.
• Export your full alias log to CSV anytime.

Privacy first: CanaryTrap runs entirely in your browser. Your alias log never leaves your device: no analytics, no third-party servers, no outbound requests.
