Where the notices come from

Contains public sector information licensed under the Open Government Licence v3.0.

Each source states its licence on the response itself, or publishes under the Open Government Licence. Tenvidra stores that URL with every notice and shows it on the match. The Open Government Licence is published by The National Archives: version 3.

Find a Tender

Publisher: Cabinet Office

Open tender-stage notices in OCDS JSON: title, buyer, description, CPV, value, deadline, delivery area and links. We request only the pages we need, and we stop when the service sends Retry-After.

Contracts Finder

Published tender-stage notices in OCDS JSON, on the same fields as Find a Tender. Below-threshold and legacy notices that still appear here are included and labelled with this source.

Public Contracts Scotland

Publisher: Scottish Government

Contract notices (notice type 2) and site notices (notice type 102) for the current month, requested as OCDS JSON (outputType 0). The publication is under the Open Government Licence v3.0. The client checks certificates. If the TLS handshake does not finish, that source is recorded as failed and the other sources still update.

How we stay inside the terms

Notice text and metadata are Crown copyright, reused under the Open Government Licence v3.0. You may reuse them commercially if you attribute the source and link to the licence.
Tenvidra is not Find a Tender, Contracts Finder, Public Contracts Scotland, or the Cabinet Office, and it does not submit bids or act as an eSender.
Some material attached to a notice is exempt from the Open Government Licence, including third-party content and logos. We store the published notice fields and document links. We do not copy website chrome.
Buyer contact names and email addresses can be personal data even though they are published. We keep them so you can respond to that notice. We do not put personal inboxes in the weekly digest, and we do not build a marketing list from them.
The services ask clients to back off when they return HTTP 429 or 503 with a Retry-After header. The ingest job honours that header and does not page past the configured limit.
Each stored notice keeps the licence URL the API returned. The match and draft screens repeat the attribution.
Public Contracts Scotland is requested from its documented OCDS API with ordinary certificate checks. A failed handshake is written to the ingest log. Certificate verification is not turned off.
