Project Sanctuary: Emotional Co-Regulation on the Wrist

What it is — in plain language

Short definitions before the architecture layer names. None of this replaces professional care; it describes a product direction.

Project Sanctuary

A product concept for a wrist companion that watches for signs your nervous system is sliding toward stress, then offers short, personalized actions to help you settle—not therapy and not a diagnosis, but timely support in the moment. A future native app would do the sensitive work on the device; this site explains the idea and runs a harmless simulation.

Emotional co-regulation

You and a tool share the job of steadying your state: the tool notices patterns and suggests the next small step; you choose what to follow. The goal is partnership with your own attention, not the tool “fixing” you.

Autonomic stress drift

Your autonomic nervous system runs heart rate, breathing, sweat, and fight-or-flight responses mostly without conscious effort. “Drift” here means those signals are trending toward a more stressed pattern compared to your personal baseline—not a medical label, just the direction the software would care about.

Soothe sequence

A short chain of actions the concept might offer in one episode—for example exhale pacing, a bounded walk, softer environment, or a one-line reframe—chosen so the sequence feels doable, not overwhelming.

Private sensing

Heart variability, heart rate, motion, and similar signals are used on-device to infer “something changed,” without treating the watch as a reason to ship raw biometric traces to the cloud for the core experience.

On-device intelligence

Small models and rules running on the watch classify how intense the moment looks and what class of response might fit (calm down, channel energy, or reframe)—always subordinate to your consent and attention.

Intervention orchestration

Turning a decision into a felt moment: one clear notification or haptic, optional links to music, home scenes, or breathing—timed and sequenced so support shows up when useful and stays quiet when you are already recovering.
