Fraud Monitor
Know before you click™
Fraud Monitor blocks known scam sites before the page loads, warns you when an online store looks fake, checks the calls, messages, numbers and images you are not sure about, and can tell someone you trust if a scam starts. Free, on the browser and on your phone.

Four ways to check something
Most scams reach you the same few ways — a link, a message, a number, or a stolen photo. The Chrome, Firefox and Safari extensions check all four.
Blocks scam sites
Phishing pages, fake shops, and crypto phishing and wallet-drainer sites are stopped before they finish loading, with a warning instead of the page.
Reads suspicious messages
Paste a message, or right-click any text on a page, and a machine-learning model scores how likely it is to be a scam.
Checks phone numbers
Look up a caller or WhatsApp number against a database of reported fraud and Do Not Call complaints.
Matches stolen photos
Romance and investment scammers reuse the same pictures. Drop an image in and it is matched against known fraud imagery.

Spots the fake shop the lists haven’t caught yet
A scam store is usually days old. By the time it is on anyone’s blocklist the orders have been taken and the site is gone. So Fraud Monitor also reads the store itself, the way an experienced shopper would, and tells you what it sees before you enter card details.
Reads the store, not just the address
Is the name trading on a brand it doesn’t own? Is there any way to contact the seller? Is the “closing down” sale permanent? Is everything 80% off? Can the payment be disputed? Each is a small sign; together they are a verdict.
Warns before you pay
In Chrome, Firefox and Safari, a bar at the top of the store says what looks wrong, in plain words. One click says you trust it and the bar stays away. Nothing is blocked — you decide, with the reasons in front of you.
On the phone too
Paste or share a store’s address to the Android app, or scan its QR code on iPhone, and the store gets the same check with the same reasons listed.
In the browser the store is read on your device and nothing it reads leaves it. The only address ever sent to us is one you ask us to check.
On your phone
The phone is where the scam actually calls you
A browser extension can only guard the browser. The Android and iPhone apps cover the three ways fraud reaches a phone — the call, the text, and the link they talk you into opening — each the way the platform allows, with the limits stated.
Blocks scam calls
On Android, set as your call-screening app, it checks each incoming number against the on-device blocklist and hangs up on the ones it knows. On iPhone it supplies the same list to the system call blocker. Anyone in your contacts is never blocked.
Warns on scam texts
An on-device model reads each incoming message and tells you when it looks like a scam, and why. On Android it warns and never touches the message; on iPhone it files SMS from unknown senders into Junk. iMessage is out of reach on both, so a message you are unsure about can always be shared to the app by hand.
Blocks scam sites
On Android a filter held on the phone refuses to resolve known scam domains, so the block applies in every browser and every app. On iPhone the Safari extension stops the page before it loads and warns when a store looks fake.

When the scam is a phone call, family can help
The most damaging scams are not links. A caller posing as the bank, Amazon or Microsoft talks someone through “fixing” a problem, gets them to install a remote-control app, and watches them log in to their bank. Fraud Monitor now interrupts that moment — and can bring in someone you trust.
Warns about remote-control apps
On Android, installing one of these apps right after a call from an unknown number sets off an urgent warning to hang up. In Chrome and Firefox, opening a remote-control app’s download page shows the same warning first.
Family alerts
Choose one person you trust. They get a short email if a scam starts — a remote-control app after an unknown call, a scam site blocked, a protection switched off, or Fraud Monitor removed from the browser — so they can call.
Consent on both sides
Nothing is sent until your family member confirms by email. The app always shows who gets your alerts, you can turn them off at any time, and they never see your messages, contacts, calls or browsing.
Family alerts are part of Premium, on Android, iPhone, Chrome and Firefox. On iPhone, where iOS shares less with apps, they cover call blocking being switched off and a weekly summary.
Privacy
Your browsing, texts and contacts stay on your device
Checking every page you visit against a server would mean sending us your entire browsing history. So we do not do that. The blocklists are downloaded to your browser and your phone and checked locally, in well under a millisecond.
- ●The list of scam sites is downloaded to you, not your history uploaded to us.
- ●An ordinary page you visit produces no network request at all.
- ●The fake-store check reads the store on your device. What it reads stays there.
- ●No account, no sign-up, no ads, and nothing about what you browse or text is tracked.
- ●On Android, the wording of your texts is judged by a model on the phone. We never see the message.
- ●Your contacts are read on the phone to protect people you know from being blocked, and are never uploaded.
- ●Manual scans send only the thing you asked us to check.
- ●Family alerts name only what happened — the scam site blocked or the app installed — never a message or a page you visited.

Free on every device you use
Install once and it works quietly in the background. Protection is free; the optional Premium subscription adds family alerts and more manual checks. The phone apps and the extensions are separate installs — most people end up with one of each.
