Useful evidence with a strict indexing boundary

The source corpus is deduplicated by the importer and grouped into defined target regions. It is used only for broad contextual outputs; the site never exposes transaction, address or parcel records.

The official DVF terms state that reuse must not enable external search-engine indexing of the data. As a conservative compliance measure, every page containing DVF-derived figures carries both an HTML noindex directive and an HTTP X-Robots-Tag. Only this methodology, source notice and privacy notice are submitted for indexing.

Risk information is shown only as commune context and keeps the official caveat that it is not a property-specific determination.
