Domain checks<br>
WEB3Alarm reads the address of a supported HTTP or HTTPS tab and extracts its hostname, including the subdomain. Automatic checks may run for open tabs at installation or browser startup, on navigation and when you switch tabs. Manual checks use the hostname from the address you enter.<br><br>

To check the domain, the extension sends its hostname to PhishDestroy (api.destroy.tools), ChainPatrol (app.chainpatrol.io), Sucuri SiteCheck (sitecheck.sucuri.net) and VirusTotal (www.virustotal.com). Sucuri may scan the submitted site. The extension omits paths, query strings, fragments, account credentials, cookies and referrer headers from these requests. The services receive the network information normally associated with a web request, including your IP address.<br><br>

Scam Sniffer matching takes place on your device. The extension downloads a public list from GitHub (raw.githubusercontent.com), including routine refreshes. This list request does not include the domain being checked. When you choose to open an external domain report or reviews, your browser visits the selected provider, including VirusTotal, Trustpilot or ScamAdviser, with the domain in the link. Those sites apply their own privacy practices.<br><br>

Local data and controls
Your preferred language stays in local Chrome storage. Temporary per-tab results include the domain, verdicts and time. They are kept in session storage, removed when a tab closes and cleared when the browser session ends. The extension also reuses recent results in memory. A cached copy of the public Scam Sniffer list can persist across sessions and is eligible for refresh after six hours. Removing the extension clears its local data.<br>v

The content script displays a warning on the page when a source flags the domain. It does not read form entries, wallet contents or payment information. The extension contains no analytics or advertising SDK, does not send a browsing log to Blockbooster Ltd and does not sell user data. Data use and transfers are limited to providing the domain checks, scores and warnings described here. External providers manage their own retention. Disable WEB3Alarm in Chrome’s extension settings to stop automatic checks.<br><br>
