CyberCleaner Pro — Web Guard (browser extension)

Last updated: 18 August 2026 · applies to version 1.2 and later

What the extension does

Web Guard warns you about online scams. It blocks scam pop-ups and unsafe websites, detects fake virus warnings and tech-support scams, and checks an email you open in Gmail or Outlook for signs of phishing. It is a companion to your antivirus, not a replacement.

Data we collect

Effectively none. We do not collect personal information, browsing history, email content, credentials, or analytics of any kind. There is no account and no login. The scam checks all run on your own device.

The only information that ever leaves your device is a question you deliberately type into the optional "Ask AI" box — and only if you choose to use it. That question is sent so it can be answered, is not stored afterwards, and is never sold or shared. If you don't use Ask AI, nothing leaves your device at all.

How your information is used

• Web pages you visit are examined on your device to detect scam and phishing patterns. The page content is never sent anywhere and is not stored after the check.
• Emails you open in Gmail or Outlook are read only while open, only on your screen, and only on your device, to check that one message for phishing signs. The extension does not read your wider inbox, does not open or fetch other messages, and never sends, deletes, forwards, or replies to any email. It never signs in as you.
• Counts of how many scams were blocked are stored locally on your computer (Chrome's storage.local) purely so the toolbar panel can show you the numbers. They are never uploaded and you can clear them by removing the extension.
• Ask AI (only when you use it) — if you type a question into the optional "Ask AI" box and press Ask, that question is sent to our own secure server, which forwards it to an AI service to generate a plain answer, and the answer is shown back to you. Only the words you choose to type are sent — never your browsing, your emails, your identity, or anything you did not type. Nothing is stored after the answer is returned. If you never use the Ask AI box, nothing is ever sent.

Data we share or sell

We share nothing and sell nothing. No third parties, no advertisers, no data brokers. Aside from the optional Ask AI feature above (which sends only the question you type, so it can be answered), the extension makes no network request that carries your data.

Permissions and why they exist

• Read and change data on websites you visit — required to detect scam and phishing pages and warn you on the spot. Processing is local.
• Gmail and Outlook access — required to check an open email for phishing. Limited to those mail sites only.
• WhatsApp Web access — to mark risky links inside chat messages. Only link addresses already on screen are read; message text and contacts are not.
• Downloads — to warn you when a program that can change your computer is downloaded, especially from a page that looked like a scam. We do not read the contents of your files.
• Right-click menu — to add the "Is this link safe?" check.
• Notifications — to alert you when a scam, phishing email, or risky download is detected.
• Storage — to remember your settings (language, simple view, your own block list) and the local block counts shown in the toolbar.
• Access to our own servers (cybercleanerproai.com and our Supabase service) — used for two things only: (1) downloading an updated list of known scam website addresses so the extension can block new scams (a one-way download of a public list; none of your data is sent), and (2) the optional Ask AI feature, which sends only the question you type so it can be answered. No browsing data, email, or identity is ever sent.

Children

The extension is a general-audience security tool and is not directed at children. It collects no data from anyone.
