What the vendor documents
Recorded from the vendor's own trust, privacy and terms pages. "Not disclosed" means we found no public statement, not that the control is absent.
What the public documentation states
Luminance pages describe Legal-Grade AI for contract review, negotiation, and due diligence. Direct fetches of the Luminance pages returned 403 during this run, so the text here uses the audit rows fetched on 2026-09-06. The August 4, 2026 hosted terms name OpenAI, AWS, Microsoft Azure, and Google Cloud as model or infrastructure providers. They state Customer Data is hosted in the AWS Region specified in the Product Order Form and, for hosted service environments, in a customer-selected AWS data centre. The audit rows state Customer Data is not sent to an external model provider for the core service, while opted-in Additional Generative Models send customer inputs to OpenAI. Learnings may improve the product only where no Customer Confidential Information or Personal Data is included. Retention rows state deletion from data stores within 30 days and backups within a further 30 days. Security rows state SOC 2 Type 2, ISO 27001:2022, dedicated single-tenant cloud, and customer-environment deployment. Pricing is by Product Order Form; no list price is published. Accuracy claims include a model-checking method, but no third-party evaluation.
In the vendor's words
“Customer Data is not sent to an external model provider.”
“Customer Data will be hosted in the AWS Region specified in the Product Order Form”
“within twenty-four (24) hours of becoming aware”
“removed from any data stores within 30 days and back up data stores within a further 30 days”
Not disclosed on public pages
"Not disclosed" records that no public statement was found where we looked, on the date shown. It does not assert that the control, term or figure is absent.
Not published on pages we read on 2026-09-06: privacy update date, list price, seat minimum, ISO 42001 statement, third-party accuracy evaluation, zero-retention term, and a blanket no-training commitment. A law-firm procurement or DPIA review normally needs these points for client confidentiality, OpenAI opt-in processing, residency proof, SRA/ABA supervision, and GDPR Art. 28 processor terms.
Questions to put to the vendor
- When Additional Generative Models are enabled, what OpenAI retention, training, and region terms apply to customer prompts and outputs?
- Which AWS Region will be stated in the Product Order Form, and what customer-selected data centre options are available?
- What evidence supports the claim that Luminance is "the most legally accurate AI on the market" beyond the published model-checking description?
- How are Learnings checked to ensure no Customer Confidential Information or Personal Data is included?
- Can Luminance provide ISO 42001 status, list price or seat minimums, and zero-retention terms?
