Question 1

Does LAURA grade automatically?

Accepted Answer

No. LAURA never assigns automatic grades. Every assessment is a proposal to the teacher; it only becomes final through their explicit release. This step is enforced by the architecture (Teacher Final Decision).

Question 2

Where does student data live?

Accepted Answer

Raw media (photos, scans) stay local on the device or in school-controlled storage. The EU database (Frankfurt) holds only pseudonym IDs, assessment and audit metadata, protected by Row-Level Security with the school as the hard tenant boundary. The real-name mapping stays local.

Question 3

What does the cloud see?

Accepted Answer

By default: no raw media. Cloud processing is exclusively opt-in and then limited to what is necessary (for example image excerpts of disputed passages, pseudonymised). There is no silent cloud escalation: it is ruled out by the architecture.

Question 4

What is the hash chain?

Accepted Answer

Every teacher decision is chained to its predecessor with a SHA-256 hash and stored append-only. Later changes break the chain visibly; the integrity of the entire history can be verified independently.

Question 5

Is LAURA GDPR-compliant?

Accepted Answer

LAURA is designed to the GDPR from the ground up: privacy by design and by default (Art. 25), data minimisation (Art. 5), EU data residency, RLS tenant separation, auditable decisions and documented processing modes. We provide the DPA template and TOM overview on request; the formal assessment is made by the school or its DPO, and we supply the documents for it.
