Frequently asked questions

The product, its limits and its licences.

Plain answers first. Technical and legal detail sits behind the relevant links.

What is DELTA in plain English?

DELTA compares the AI or automated system you approved with the version you want to release. It shows what changed, what still stands and what you need to update, reassess or stop.

When should we use it?

Use DELTA before releasing a material or uncertain change to a model, provider, purpose, dataset, inference, population, integration, tool permission, degree of autonomy, human-oversight arrangement or control environment.

Does DELTA decide whether a change is a “substantial modification” under the EU AI Act?

DELTA can identify facts relevant to that legal question and can trigger specialist review or renewed conformity work. It does not reduce every change to one statutory label or provide a binding legal determination.

Does DELTA replace a DPIA, FRIA or conformity assessment?

No. It identifies whether the change may require those assessments to be opened, updated or repeated. The specialist exercise remains separate.

Does it produce a compliance score?

No. DELTA produces one of five reasoned routes: Record only, Documentation update, Targeted reassessment, Full reassessment or Deployment hold.

Can we override the automated route?

An authorised decision-maker may adopt a stricter route. Any departure must record the person, authority, reasons and evidence. The product should not support an unexplained weakening of the triggered outcome.

What happens when the answer is “Not sure”?

DELTA treats uncertainty as information. A material unresolved issue can create an evidence gap, targeted reassessment or deployment hold. The tool does not silently convert uncertainty into approval.

Where does the assessment data go?

The browser application processes answers on the user’s device. Optional local save uses the browser profile. JSON export leaves the device only when the user chooses to store or share the file. Ordinary website hosting may still create server logs for page requests.

Is local browser storage encrypted?

Not by DELTA 0.3. The current prototype uses browser localStorage and relies on the security of the device, user account and browser profile. Users should not treat local save as an encrypted records repository.

Can we use the public demo for a real change?

No. The public demonstration contains fictional facts and produces a watermarked sample. A live organisational decision requires the appropriate licence and current methodology.

What does the £395 licence cover?

It covers one named legal entity, one identified system and one defined baseline-to-revised change event, subject to the definitive licence terms and completion window.

What does the organisation licence cover?

It covers repeated internal assessments by one named legal entity during a twelve-month term, together with standard methodology and rule-pack updates released during that term.

Can a law firm, consultancy or auditor use DELTA for clients?

Not under the standard single or organisation licence. External-client, adviser, group and white-label use require separate terms.

Does a DELTA report amount to legal advice or independent assurance?

No. The report records structured decision support based on entered facts and the selected rule pack. Expert review, legal advice and independent assurance remain separate services.

How often should we reassess?

Reassess on the recorded review date and whenever a defined trigger occurs, including a new purpose, model, provider, dataset, population, tool connection, incident, regulatory change or material control failure.

Still unclear?

Start with the fictional change.
