Security

Security and compliance, explained without the small print.

Encryption at every step, infrastructure in the EU, a record of reviews and a data processing agreement ready to download.

Always encrypted

Encrypted connections and, if you keep files, AES-256 encryption with a different key for each account.

Infrastructure in the EU

Servers in Spain and stored data in the EU. AI analysis is carried out by Cloudflare Workers AI, which does not keep the documents or train on them; the sovereign profile uses European providers only.

Audit trail

Every review decision is recorded with who made it, when and why.

GDPR

We act as a data processor, with minimum data and no copies by default, in line with the data minimisation principle.

Frequently asked questions

Where are documents processed?

Our servers are in Spain and the data you keep is hosted in the EU. By default, AI analysis is carried out by Cloudflare Workers AI on its network, without keeping the documents or training on them. With the sovereign profile, the analysis is done with European providers only.

Can you sign our data processing agreement?

On the Enterprise plan we sign a tailored DPA. On the other plans, you can download ours.

What happens if there is a security incident?

We notify you without undue delay, as the GDPR requires and the DPA sets out.
