DPA, privacy policy, sub-processor list, legal notice and pricing page read and recorded below, each with its source.
How this was researched: AI-assisted. An AI assistant retrieved the vendor’s pages and linked every answer to the source where it appears. Where a page couldn’t be read, it says “unclear” – not a guess. An editorial spot check is still pending; please report errors via the correction form.
Not tested hands-on yet, so there is no rating. The full review adds that.

“Unclear” means we didn’t find the information in the public documents – not that the vendor doesn’t meet it. The check is a documented snapshot of the vendor’s public commitments. It is not a certification and not legal advice – see the disclaimer.
