Privacy and Personal Data Protection Policy

We, Neuro Event Labs Oy (NEL), believe that your privacy is critically important. That is why we handle your personal data with great care.

This document describes what personal data we gather, why we gather it, and how we manage and store the data.

Nelli® as a term used in this document refers to the epilepsy examination service provided by NEL. Nelli® system refers to the information system that is used in the Nelli® service.

Our principles for privacy and personal data

We apply these basic principles to all personal data that NEL stores and processes. The data can broadly be categorized as follows:

  • raw media of patients captured by the Nelli® system
  • summary biomarker data derived from the raw media in the Nelli® system
  • data about users and patients (e.g. contact information) within the Nelli® system
  • data used in NEL’s business processes about NEL employees, applicants, business associates, and prospective customers

In each of these categories, we gather and store only the personal data that is required to provide the Nelli® service and conduct NEL’s business operations. Personal data is disclosed only to parties and persons on a need-only basis and only for the purpose it was collected. Each NEL or contractor employee who has access to the personal data is contractually obligated to safeguard and maintain confidentially of such data.

No personally-identifiable information is retained or transferred to a third party beyond the data processors mentioned in this document. Where possible, data is stored in such a manner (e.g. encrypted) that the third-party service provider cannot derive any meaningful information from data which is stored or processed by that provider.

We follow all applicable local and regional laws for data protection, including the European General Data Protection Regulation (GDPR), the US Health Insurance Portability and Accountability Act (HIPAA) Security, and Privacy Rules.

Cookie Policy

NEL does not use cookies to track its users’ usage of the NEL website or the Nelli® system. Cookies are used only for functional purposes, e.g. to manage a secure user session with Nelli®.

Data we collect in Nelli®, why, and what

Patient data

Patient data, also known as Protected Health Information (PHI), is collected by NEL in order to provide source material for the Nelli® examination service. This service provides an analysis of epilepsy patient recordings which occur in an inpatient (e.g. hospital) or an outpatient (e.g. home) setting. The analysis results in a report that aims to track and quantify seizure activity. This report serves as a medical record and presents the results of the analyses requested by the clinician.

Patient data includes:

  • Patient identification: name and birthdate: needed to identify the patient uniquely in the system
  • Optionally, patient contact information, including residence address: needed in the case of outpatient home examination
  • Optionally, caregiver contact information: needed in the case of outpatient home examination
  • Requested examination periods: needed as input for examination planning and execution
  • Raw video, audio, and other sensory data from examination periods: needed as input data for analysis
  • Analysis data: the results of automatic and manual analysis. Analysis data may contain automatically-detected neurological events (like seizures) and vital measures (e.g. breathing rhythm and pulse) as well as manually-added annotations
  • Analysis reports: processed summaries of analysis data. Reports are available for online viewing and as PDF documents for the Nelli® system users

All data collection by the Nelli® service is volunteered by the NEL customer (hospital/clinic) and the patient as a part of the healthcare plan of the patient. For the purposes of the service, NEL serves as a data processor and assumes no legal ownership of the raw data. Depending on the jurisdiction, the data may be considered controlled by the customer organization (e.g. in a form of public health records) or the patient.

Derived summary biomarker data is considered to be an artifact of the Nelli® system, which, when detached from its patient profile, is considered to be non-sensitive and non-personally-identifiable. This data can be detached from all identifying characteristics and retained for the continuous improvement and quality assurance of the Nelli® system. Such terms are made in agreement with every NEL customer.

User data

Users of the Nelli® system are doctors and clinicians from the customer organization, as well as NEL personnel providing the Nelli® service for the customer. User data is collected by NEL in order to give controlled and audited access to the Nelli® system.

Data collected about Nelli® users includes:

  • Nelli® user identification: name and email address. Needed to identify the user in the system
  • User access rights: patient registers and privileges within registers
  • User activity logs: all user access to the system and read or write of patient data is logged for auditing purposes

Nelli® data storage and processing

The Nelli® system consists of a dedicated data collection unit (Personal Recording Unit – PRU), a cloud-based server infrastructure for data analysis, and a web-based dashboard for viewing the results of analysis.

The PRU is designed by NEL using industry-standard components and security measures to protect collected patient data before sending it encrypted to the cloud for processing. Data is stored in the PRU only temporarily. All data is stored encrypted at rest.

The Nelli® system is implemented using Amazon Web Services (AWS). AWS as a data processor uses the shared security responsibility model and is compliant with HIPAA requirements for Protected Health Information (PHI).

Personal data is stored, encrypted while at rest, in AWS cloud services and the data travels over a secure channel (TLS 1.2) when being transferred between data processing steps.

Data storage and processing are done in a private network with no public internet access.

Personal data is stored and processed in the geographically optimal AWS data center in relation to customer operations.
