Danger Stamp

Stamps scam pages, emails, chats, comments and ads before you fall for them.

Danger Stamp warns you about scams on the pages, emails, chats, comments and ads you see, and tells you in one plain sentence what to do instead. WHAT IT DOES • Stamps scam pages: fake sign-in pages, fake shops, fake tech-support and virus warnings, fake parcel, toll and tax notices, crypto and investment traps. • Locks the form on a scam page so a password or card number can't be typed in by mistake. A risky download (an installer, a script, a remote-access tool) is paused for a few seconds while the page it came from is checked, and cancelled if that page turns out to be a scam. • Checks the email you have open in Gmail, Outlook, Yahoo and other webmail, and chats in the web versions of popular messengers, for warning signs like a payment request, a code or a first message from a stranger. • Marks scam comments and ads on social media. Optional: a low-quality content warning on posts that read like AI-written filler (off unless you turn it on). • Explains every warning in plain words: what's wrong, what to do now, and the steps to take if you already gave them something. You can send a short note to someone you trust. • "Check this": right-click any text you're unsure about, or paste a message into the toolbar button. • Quiet on normal pages. Child mode and a family plan for looking after parents and grandparents. HOW TO USE 1. Add Danger Stamp to Chrome. It starts on the next page you open. 2. When something is a scam, a red stamp lands on it and a bar at the top says why. Press WHAT TO DO for the next steps. 3. Something fine was stamped? Press FALSE ALARM to unlock it, or to always trust that site. FREE AND PRO Free runs every check on your computer and never sends what you read anywhere. Pro and Pro Family ($4.99 a month, or $12.99 a month for 5 browsers) add an AI check for the cases that need it. You turn it on yourself: when something looks risky, a short snippet is sent to our server with card, account and ID numbers and other people's email addresses blanked out. Nothing is kept. PRIVACY We never sell your data, show you ads or use what you read to train AI. You can switch email and chat checks off in one click.
