What the badge tells you

One colour, one number, every site

The badge on the toolbar icon updates when you switch tabs or open a new page. Click it for the verdict and the four key signals.

12
Low Risk

Scam Score below 30. No relevant warning signs found.

41
Uncertain

Score 30–50. Mixed signals — look for independent reviews.

63
Suspicious

Score 50–70. Several warning signs. Be careful with payments.

92
High Risk

Score above 70. Very likely a scam — do not enter personal data.

✓
Verified business

The company behind the site passed our identity checks. Verification never changes the score.

Features

Everything you need to shop safely

Scam Score in the toolbar

Green, yellow, orange or red with the score on top — so a fake shop stands out before you reach the checkout.

The verdict in one click

Threat detection, popularity, domain age and server country, the “Verified business” label and when the report was last updated.

High-risk warning

Optional banner on sites above your threshold (default 70) — dismissible, and it never reads the page.

Check links before you click

Right-click any link → “Check this link with websurely.com”. Perfect for links in e-mails, ads and messages.

Scan unknown sites

No report yet? Press “Scan now” and watch the result arrive — usually in under a minute.

Report & review

Report a scam or leave a review straight from the popup. Results our team checked by hand are marked “Manually reviewed”.

Privacy by design

We never learn which pages you visit

Automatic checks use a hash prefix: your browser computes a SHA-256 fingerprint of the hostname and sends only its first 4 characters. Our server answers with every rated site that shares those characters — thousands of possible sites — and the match happens on your device.

shop.example.com→ sha256 3aeb9f…→ sends 3aeb→ match locally

  • Hostname only — never full URLs, paths, search terms, page content or cookies.
  • Consent first — automatic checks start only after you agree; otherwise only on click.
  • No incognito — private windows are never checked.
  • Anonymous — a random install ID for rate limiting and aggregated statistics; no account, no tracking.
  • No history on our servers — only daily counters per install, never a list of domains.
  • Local cache — results stay on your device for 24 h and can be cleared in the settings.

FAQ

Questions about the extension

Is the extension free?
Yes. The websurely.com Scam Checker is free for Chrome, Firefox, Edge, Brave and Opera. There is no account, no subscription and no advertising.
Does the extension see which websites I visit?
No browsing history is sent or stored. With automatic checks enabled the extension only sends the first 4 characters of a SHA-256 hash of the hostname — thousands of sites share each prefix — and compares the answer on your device. The plain hostname is only sent when you open the popup, use "Check this link" or press "Scan now". Full URLs, paths, search terms, page content and cookies are never sent.
Why do I have to agree before automatic checks start?
Because the extension asks our server about the sites you visit, even if only in anonymised form. Until you agree on the welcome page (or in the settings) a site is only checked when you click the toolbar icon.
What do the badge colours mean?
Green = Low Risk (Scam Score below 30), yellow = Uncertain (30–50), orange = Suspicious (50–70), red = High Risk (above 70), a blue tick = Verified business, grey "?" = not rated yet or a scan is running.
What happens in private or incognito windows?
Nothing. The extension is not allowed to run in private windows and never checks a site opened in one.
Why does a site I trust show a high score?
The Scam Score (BETA) is calculated automatically from public signals such as domain age, popularity, SSL and threat feeds. Results can be wrong — open the full report to see why, leave a review, or request a manual review. Results that our team checked by hand are labelled "Manually reviewed".
How do I turn on the warning banner?
Open the extension settings and switch on "Show a warning banner". Your browser asks for permission to display the banner on any website; the extension never reads page content. You can choose the score threshold (default: above 70).
