Data policy
What Lumen keeps, where it stays, and who can see it.
This page summarizes how Lumen is meant to be used. The agreement signed with your hospital takes precedence if the two differ.
Patient data stays on site
Identifiable patient data stays on the hospital network. It does not leave the site, and it is not sent to the cloud.
Pseudonymous patient key
Clinical services work with a patient key, not a name or record number. The link back to the person is held in one separate, encrypted store.
What is recorded
For every finding: the model version, the input fingerprint, the threshold and the clinician's action. Every change is also written to the audit log.
What the cloud sees
Only operational information such as service health and approved model updates. No patient data and no images.
Who can see it
Access follows your role, site and purpose. Each request is checked on the server, and signing out clears the data shown in your browser.
Retention and your rights
Your hospital sets retention and handles access, correction and erasure requests under the applicable data protection law, including the DPDP Act.
Website privacy
