Passive monitoring, on your phone

Your nervous system
tells a story
before you do.

NeuralShield is a phone app that runs quietly in the background of your day, learning your normal from the rhythm of your voice, the cadence of your typing, and your resting pulse — so meaningful changes can be noticed early, against your own history.

Start building your baselineHow it works

Three signals.

One picture.

Voice

The rhythm of speech. Duration of pauses. Micro-variations in pitch that change imperceptibly with neural state — captured during ordinary conversation, never recorded or stored.

Typing cadence

The interval patterns between keystrokes. The time it takes to find the next word. Not what you write — only the timing between presses, encrypted locally before transmission.

Resting pulse

The subtle signal at your wrist or face, read passively from camera during video calls. Heart rate variability. The breath behind each sentence — a window into autonomic function.

NeuralShield runs in the background of your day. No special sessions. No effort. No disruption to how you already live and work.

Not a score.
A portrait of how you
move through the world.

Most health apps show you a number and ask you to worry about it. NeuralShield builds a model of you — your specific patterns, your personal rhythm — so that meaningful shifts can be noticed against your own history, not a population average.

The baseline refines continuously. The longer you use it, the more precisely it reflects who you are on an ordinary day.

YOUR RANGE

Day 16 monthsToday
Your baseline grows more precise over time, bounded by your own normal range — not a population threshold.

For you and those
who care about you.

The same data reads differently depending on who you are and what you need. NeuralShield lets you choose who sees what, and when.

For you

Track your own rhythm — on your own terms.

See your baseline over time. Notice your own patterns. Decide what to share, with whom, and when. NeuralShield never surfaces alarming language — only context for conversations you choose to have with your care team.

For your care circle

Stay close without constant questioning.

When something worth discussing emerges, NeuralShield surfaces it gently — the right moment, the right context, not an alert. You get continuity, not anxiety. Your loved one keeps their autonomy.

Your data stays yours.

Encrypted locally

Raw signals — keystrokes, audio features, pulse readings — are encrypted on-device before anything leaves your phone.

You control sharing

Nothing is shared with family members, clinicians, or anyone else without your explicit consent — granular, revocable, always.

GDPR by design

Data minimization, right to erasure, and purpose limitation are built into the architecture — not bolted on after the fact.

The sooner you start, the more precisely NeuralShield can understand what’s normal for you — and what isn’t.
