## Description

<strong>Tenure - Zero-Click Website Age Checker</strong>

Tenure shows you how long any website has been registered, helping you avoid scams and phishing sites before you ever click a link. Fast, distraction-free, and privacy-first.

<strong>See website ages right in your search results</strong>

Tenure overlays domain registration age directly in your Google and DuckDuckGo search results with no clicking required. Spot newly registered domains at a glance and skip the sketchy ones entirely. Works great alongside tools like uBlacklist for keeping your search results clean.

<strong>On-demand lookups, anytime</strong>

Click the extension icon on any site and Tenure performs a direct RDAP query from your browser to public RDAP servers approved by IANA. The result stays entirely on your device, we never see or record your lookups.
