Every market we publish, who publishes it, and the exact licence it is used under.
DeedStone does not collect or own this data. Every market is published by a national authority and remains theirs. We download the official published files, clean and aggregate them, and publish derived statistics — medians, counts and price levels. We do not republish the raw registers as a dataset.
We are not affiliated with, and are not endorsed or certified by, any of the authorities below. We are an independent service that reuses public data under the terms shown.
Attribution is shown here and on each market. If you republish a figure from DeedStone, keep the original register's attribution with it — the exact wording each licence requires is below.

Licence names and links verified against the publishers' own pages on 10 September 2026. Where a market's register publishes only aggregates or starts recently, we say so in the app and in every export. Coverage notes are listed on the Data and AI disclaimer page.
If you republish a figure we derived from one of these registers, the licence needs the original source credited. These are the forms the publishers ask for — copy the one that applies.
Reference exchange rates are provided by open.er-api.com (mid-market, indicative, refreshed daily). They are references only and not transaction rates. Every converted figure in the app and in exports carries an as-of stamp.
If you publish one of these registers and believe our use or attribution is wrong, contact r7adco@gmail.com and we will fix it or remove the market promptly.
