Design Your Study as a Program
LLIF provides ethical, consent-driven data infrastructure for longitudinal health research — with participants collecting data through apps they already use.
Studies as Programs. Data with Consent. Infrastructure That Outlives Your Grant.
Your study becomes a Program — with defined data requirements, collection compliance, participant onboarding, and insight outputs. Participants subscribe through apps and collect data on their terms.
Consent-First Architecture
Participants opt in. They see exactly what data is collected and why. IRB-compatible consent built into the infrastructure.
Compliance-Driven Collection
Define data requirements, schedules, and targets. The platform tracks compliance automatically — including historical data prerequisites.
Nonprofit-Protected Data
Data classified as a donor-restricted asset. No resale, no secondary exploitation — with bankruptcy protections. Trust by structure, not by policy.
Built-In Analytics
Correlations, trends, calendar patterns, predictions, and community-level anonymous insights. Or export raw data for your own analysis.
Environmental Enrichment
25+ weather, AQI, and pollen metrics attached automatically. The environmental context that makes population health studies actionable.
Outlives Your Funding
Nonprofit infrastructure doesn't depend on your grant cycle. Participant data remains available for follow-up with renewed consent.
Include LLIF in Your Grant Proposal
Budget templates, boilerplate language for data management plans, and letters of support — for NIH, NSF, PCORI, and foundation proposals.
