Luminance publishes a detailed UK GDPR privacy policy with a full data processing addendum, a named subprocessor list and a 24-hour breach notice, but its terms take a perpetual licence over uploaded User Data and name no retention period.

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

Perpetual licence over uploaded data

The terms grant Luminance a non-exclusive, perpetual, royalty-free licence of User Data so the service can analyse, retain and reuse usage results, Outputs, learnings and trends, even though users keep title to the data itself.

Generative AI opt-out is narrow

Customers can disable the Additional Generative Model functionalities, including Ask Lumi, by raising a support ticket, but that switch does not cover the broader service-improvement use of uploaded data.

Strong processor commitments

The addendum names an ISO 27001 certification, a 24-hour personal data breach notice, a three-day data subject request notice and a subprocessor table listing AWS, Microsoft Azure, Google Cloud and OpenAI.

No retention period, and change notice is disclaimed

The policy names no retention period for personal data, keeps User Data for only thirty days after a termination notice before deletion, and reserves the right to amend the policy at any time without notice; it was last amended on 27 July 2023.

What the policy is silent or vague on

Not stated: whether training use differs by plan
Not stated: your ownership of generated outputs
Not stated: a retention period for your data
Not stated: shorter retention for AI conversation logs
