What we provide

Technology adoption data delivered by API, CSV export and email. Accuracy figures are published per technology and per product; they are measurements, not guarantees, and we state the sample size and interval behind each one.

Accuracy

We do not warrant that any row is correct. We warrant that we measure accuracy honestly and publish what we measure, including failures. If you find a row that is wrong, tell us — reported errors feed the next audit.

Acceptable use

One key per workspace, shared with your team. Do not resell raw exports as a competing dataset. Do not use the data to target individuals; it describes companies and their websites.

Attribution

Exports carry required attribution for HTTP Archive and People Data Labs. Those lines must remain on redistributed extracts. See attribution.

Billing

Plans are billed monthly in advance and priced by technologies watched. A technology suspended after failing re-audit stops counting against your quota and is credited on the next invoice. Cancel any time; access continues to the end of the paid period.

Termination

Either side may end the agreement at any time. On termination we delete your workspace, keys, lists and watches. Aggregate crawl data is not personal and is retained.
