Human voices
A calm routine is the goal. These are wellness-oriented experiences, not medical claims.
Proof matters. So does responsibility.
We’re building EVY Platform to be calm, usable, and trustworthy. We keep “proof” grounded by linking to sources and clearly distinguishing between peer‑reviewed research and company‑reported outcomes.
- Safety and adherence in real daily use
- Cognition endpoints (e.g., MMSE and related measures)
- Imaging endpoints (e.g., MRI‑based measures)
We link to sources and label them clearly: peer‑reviewed vs company‑reported. If a claim can’t be sourced, it doesn’t ship.
Built to hold real user data safely
This repo treats security as architecture. Tenancy is enforced at the database layer, and cookie auth is protected with CSRF defenses. That’s how you build something that lasts.
Simple answers, calm clarity.
We keep it straightforward so you can decide with confidence.
