description: >-
  Planomy publishes three embeddable calculator widgets. They are a genuine client-side integration
  surface — a second, browser-native way to consume the same figures the tax-data JSON exposes — and
  they are free to embed on commercial sites. Distinct from server-side SDKs; there are none of those.

terms:
  cost: free
  account_required: false
  commercial_use: allowed
  attribution_required: true
  attribution_detail: >-
    A visible, followable "Powered by Planomy" link must remain. The widget may not be presented as
    your own product and the attribution may not be stripped.
privacy:
  cookies: false
  local_storage: false
  analytics: false
  network_calls_after_load: false
  detail: >-
    Planomy states all computation happens client-side in the visitor's browser with no cookies,
    localStorage, analytics or external network calls after load.
indexing:
  robots: >-
    The three widget documents carry <meta name="robots" content="noindex, follow">. robots.txt
    deliberately does NOT disallow /embed/, so the "Powered by Planomy" backlinks stay crawlable —
    the noindex only keeps the stripped framed copies out of results in favour of the full calculator
    pages.
relationship_to_api: >-
  The widgets and the tax-data JSON are siblings, not layers: the widgets are a rendered surface for
  humans on someone else's page, the JSON is the same underlying figures for machines. Neither is
  documented in terms of the other.
