Compliance and transparency about the domain data we are authorised to use.
We access gTLD zone files through ICANN CZDS or equivalent registry-authorised access mechanisms. We use zone files for internal diff computation, lifecycle analysis, and quality scoring. We do not redistribute, expose, or resell raw zone-file data in any form.
We publish derived analytics only: domain names, observed status transitions, lifecycle labels, Domain Quality Score and explanations, Wayback snapshot counts, keyword categorisation, and aggregated context. We do not publish full zone files, bulk zone-file exports, or registry-provided raw zone datasets.
We use the public Wayback CDX API to count historical snapshots and estimate first-seen years for domain names. We cache results, throttle requests, and back off when rate limited to reduce load on the Internet Archive.
Registration status checks use RDAP, the modern replacement for WHOIS, at registry-provided endpoints. We query RDAP to verify lifecycle status, respect rate limits, cooldowns, and Retry-After responses where provided, and do not store or republish registrant contact details.
Raw zone files are retained for no more than 90 days, used only for diff computation and lifecycle analysis, then deleted. Derived drop records, DQS outputs, and domain lifecycle history are retained indefinitely as our historical analytics dataset. Temporary processing files, backups, and logs may exist during normal operations but are pruned under our retention policies where applicable.
NameNotifier is not a domain registry, registrar, or drop-catching service. We provide monitoring, analytics, and alerts based on observed data.
If you represent a TLD operator and have a concern about our use of zone data, please open a compliance support ticket.
