Upgrade

Unlock the full picture.

Premium adds Google's enterprise threat intelligence on top of the free sources and expands every verdict into a full signal-by-signal report. Your subscription is linked to your browser, not to an email account — so there's nothing to sign up for.

How checkout works

The purchase flow starts inside the extension popup, not on this page, so your subscription gets tied to the right browser automatically.

  1. 1 Open any website, click the Sitelight shield in your Chrome toolbar, then click Upgrade to Premium in the popup.
  2. 2 Stripe's secure checkout page opens in a new tab. Enter your card details and complete the form.
  3. 3 Stripe redirects you back here with a success confirmation. The extension is already polling in the background and will show the Premium badge within about 30 seconds — no browser restart, no re-install.

What Premium actually gets you

Detailed site report

Click the shield on any site and you'll see the full signal breakdown behind the verdict: registration date, HTTPS state, popularity, name shape, and the specific rule that fired. Free tier shows a one-line reason; Premium shows everything we looked at.

Google threat intelligence

Premium routes every safety check through Google's enterprise Web Risk API on top of the free sources. That's broader phishing and malware coverage than we can surface otherwise.

Priority support

Email [email protected] and you'll hear back from a real person the same day on weekdays. Free-tier email gets answered too — just slower.

Manage & cancel anytime

The options page has a Manage subscription button that opens Stripe's own customer portal. Cancel, update your card, or download invoices — Premium stays active through the end of the period you've already paid for.
