Privacy Policy
WhoIsAge processes domain names only to provide its popup and optional SERP features. No accounts, stored browsing history, or data selling.
What WhoIsAge reads
WhoIsAge reads the hostname of the active tab after you open the extension, a domain you manually submit, and destination hostnames from visible organic results on supported Google Search pages when the SERP panel is enabled. It does not continuously monitor other browsing, read search terms or snippets, or read page content unrelated to these domain-age features.
For Chrome Web Store disclosure purposes, this includes limited web history data (the active hostname being checked), limited website content (organic-result destination hyperlinks), and location data in the form of the requesting IP address processed for abuse prevention. WhoisAge does not collect precise GPS location.
How a lookup works
WhoIsAge first checks IANA's public RDAP bootstrap list. For supported top-level domains, it sends the hostname to RDAP.org and the authoritative public RDAP service. For unsupported or incomplete records, it can send the hostname to the WhoIsAge service at whoisage.com, which retrieves registration data from WhoisFreaks. If registration data is unavailable, it may send a nameserver query to Cloudflare's public DNS-over-HTTPS resolver.
What is stored on your device
- IANA's public list of RDAP-supported TLDs and the ICANN section of the Public Suffix List, cached for up to seven days to resolve hostnames to registrable domains.
- The latest daily live-WHOIS allowance count and its reset time, so the counter displays between lookups.
- SERP domain-age lookup results, cached locally for one day for public RDAP results and up to 30 days for live-WHOIS results to avoid duplicate network requests and paid lookups.
WhoIsAge does not maintain a general browsing history. Cached SERP entries contain only public domain-registration metadata and are used solely to provide the domain-age feature; they are not uploaded as a browsing profile.
Google Search results panel
On supported Google Search pages, WhoIsAge reads the destination hostnames attached to visible organic-result headings to build the optional SERP age panel. It does not read search-result snippets, your search terms, account information, or unrelated page content. RDAP-supported domains are checked automatically; domains without public RDAP are only sent to the live WHOIS service after you click Show age. The panel can be dismissed at any time.
Daily allowance & your IP
For live WHOIS lookups, WhoIsAge uses a one-way hash derived from the requesting IP address to enforce a daily allowance. The raw address is not stored in the quota database. Public RDAP checks and cached WHOIS results do not use the daily allowance.
No credentials, no selling
WhoIsAge does not require a user account, does not sell data, and does not store browsing history or build a browsing profile. The published extension does not contain third-party API credentials and does not request raw WHOIS personal-contact records.
Limited Use
Information received from Chrome APIs and supported web pages is used only to provide and improve the user-facing domain lookup features described above. Its use complies with the Chrome Web Store User Data Policy, including the Limited Use requirements. It is not used for advertising, creditworthiness, or unrelated profiling.
Third parties
IANA, PublicSuffix.org, Vercel, WhoisFreaks, RDAP.org, Cloudflare, and authoritative domain registries process lookup requests under their respective policies.
