Paste it into the toolbar button

What the answers mean
- A stamp or a warning names the scam and opens the same What to do panel as any other warning.
- "Worth a closer look" (Free) means it found warning signs but the AI check that tells a scam from a false alarm didn't run. Treat it as a maybe.
- "No warning signs found" means exactly that. It is never a promise that something is safe. A scam with no familiar pattern, or one told over the phone, can still get past it.
What leaves your computer
Only what you chose to check, and only because you asked. On Free, the checks run on your computer and nothing is sent. On Pro with AI checks on, the text goes to our server with card, account and ID numbers and other people's email addresses blanked out first, is checked, and is not kept. Checks from the website work the same way. The details are in our privacy policy.
