How we reached this
French legal entity: Hikoo SAS, 4 rue Michel Luciani, 91330 Yerres, RCS Évry 100 812 817, VAT FR29 100 812 817, from tryhikoo.com/en/legal-notice/. Exposure US_CLOUD_ACT, and this one is evidenced rather than assumed. The legal notice names Vercel Inc. of Walnut, California as the host of the frontend and application, and Microsoft Ireland Operations Limited (Azure, Dublin) as the host of the server, API and database. A US company holds the application layer, and Microsoft Ireland is the Irish subsidiary of a US parent, which is the arrangement the CLOUD Act was enacted to reach. Data hosting location is recorded as EU because the database is in Dublin; the tool is EU-hosted and US-reachable at the same time, which is why those two fields are kept separate. PARTIAL rather than COMPLIANT: the controller is identified, transfer safeguards are named (EU-US Data Privacy Framework adequacy for certified processors, Standard Contractual Clauses for the others) and retention criteria are set out, but processors are listed only by category rather than named, so a reader cannot verify who holds what beyond the two hosts above. Schrems II risk MEDIUM: real transfers to the US, with safeguards stated. No DPA is published and none appears to be required: section 1 names Hikoo SAS as the data controller, and the product audits public websites and competitors rather than processing personal data on a customer's behalf, so there is no Article 28 controller-to-processor relationship to paper.

Hikoo GDPR & data protection: common questions
Is Hikoo GDPR compliant?
Partly. Hikoo meets some of the requirements, with caveats worth reading before you commit. Hikoo is a European company headquartered in France, data is hosted within the European Union.
Where does Hikoo store data?
Hikoo states: "Legal notice section 3: frontend at www.tryhikoo.com and app.tryhikoo.com hosted by "Vercel Inc., 340 S Lemon Ave #4133, Walnut, CA 91789"; "Server / Backend (API, database)" hosted by "Microsoft Ireland Operations Limited (Microsoft Azure), One Microsoft Place, South County Business Park, Leopardstown, Dublin 18". — tryhikoo.com/en/legal-notice/, last updated 2026-07-14, read 2026-08-24.". Data is hosted within the European Union.
Does Hikoo offer a Data Processing Agreement (DPA)?
We could not locate a published DPA for Hikoo. That does not mean one is unavailable. Many vendors provide it on request or inside the account area rather than publishing it. Ask before you sign.
What a DPA has to cover →Is Hikoo a European company?
Yes. Hikoo is headquartered in France and, as far as we can establish, European-owned.
Is Hikoo subject to the US CLOUD Act?
Indirectly. Hikoo itself is European-owned and headquartered in France, so the company is not subject to US jurisdiction. The exposure runs through a US provider in its processing chain, a host, CDN or other sub-processor, which can be compelled to disclose data it holds even when that data sits on EU servers. That is a narrower exposure than a US-owned vendor, and the compliance notes above say which provider it is. Standard Contractual Clauses are in place for transfers, which is the required safeguard but does not override a lawful US order.

Spotted something wrong?
Martech moves fast. Vendors change hosting regions, get acquired, publish a new DPA or rewrite their pricing, and they rarely announce it. We check what we publish and date every compliance review, but some of what you see here will be out of date before we catch it.
