What Luminance's privacy policy and terms of service say about your data

Perpetual licence to improve the service

The terms let Luminance access and use any User Data to operate, maintain and improve the Services, including retaining and analysing Outputs, learnings and trends, under a perpetual royalty-free licence. The opt-out that exists covers only the Ask Lumi generative features and is exercised by raising a support ticket.

No retention period stated

The policy names no retention period and no shorter retention window for AI prompt logs. The one concrete number is a thirty-day window after a termination notice, during which customers can download or delete their data before Luminance deletes all copies.

Strong supply-chain and security disclosure

An appendix names each subprocessor, including AWS, Microsoft Azure, Google Cloud EMEA and OpenAI, with its location and the data it sees. The DPA commits to notifying the customer of a personal data breach within twenty-four hours and to supplying a current ISO 27001 certificate on request.

Rights and change notice are qualified

Access, correction, erasure, objection and portability are all offered, though erasure may be refused for legal reasons and portability is limited to data originally provided under consent or contract. Luminance reserves the right to amend the policy at any time, for any reason, without notice.

What the policy is silent or vague on

Not stated: keeping user inputs out of model training
Not stated: whether training use differs by plan
Not stated: your ownership of generated outputs
