Personal Data OS & Digital Self

A Personal Data OS unifies signals and moments into one private, portable Timeline you control.

Why you need a Personal Data OS 

Your health and life live in silos. You get fragments: numbers without story, events without metrics. That makes it hard to:

  • Spot patterns across sleep, stress, work, travel.
  • Explain changes to yourself (or a clinician) with evidence.
  • Run small experiments and know if anything actually worked.
  • Use AI assistants meaningfully.

What A Personal Data OS is 

  • A layer above apps that unifies data + life events in one timeline.
  • Adds context (notes, tags, location, environment) so metrics have meaning.
  • Built for sharing and AI with granular scopes, time-bound links, and exports.

What a personal data OS isn’t

  • Single-purpose (steps, macros, workouts), each with its own view.
  • Static charts and monthly recaps; little context.
  • Sharing PDFs or screenshots is hard to keep current.

How Context works as your OS 

  1. Timeline — A single, filterable stream of your health and life (sleep, HRV, workouts, meetings, travel, symptoms).
  2. Annotations & tags — Quick notes for mood, energy, meals, meds, and events to explain the why behind the numbers.
  3. Location & environment — Auto-capture trips, time zones, weather/light; see how place and season affect you.
  4. Integrations — Apple Health, Oura, WHOOP, calendar, and more; import labs; attach files.
  5. Life API — Bring your own AI/agent. Answer questions using only the scoped data you approve; revoke anytime.

Add what you have now; grow over time. Your OS stays stable even as apps change.

Core use cases

  • Sleep & recovery — Connect wearables, annotate evenings, and learn the routines that protect tomorrow’s energy.
  • Life transitions — New job, parenting, surgery, perimenopause: make before → during → after visible. 
  • Personal experiments — 2–6 week trials (meal timing, caffeine, training load). Then‑vs‑now comparisons, not vibes.
  • AI readiness — Ask your assistant to make you an end of week recap. Context sends only the last 7 days it needs.
Context's Shared Awareness

Ownership, privacy, and exports

  • You own your archive. Keep history across devices and apps.
  • Granular sharing. Create redacted, time‑bound snapshots for clinicians, coaches, or partners.
  • Least‑privilege agent access. Let your AI read just enough to answer a question; audit and revoke in one tap.

Getting started: your first 30 days

Day 0–3: Connect & orient
  • Connect Apple Health / wearables / calendar; import recent labs.
  • Add Annotations you’ll actually use: energy, stress, late meal, alcohol, travel.

Week 1–2: See your baseline
  • Skim the Timeline each morning; record your Annotations.
  • Annotate obvious events (late nights, tough workouts, travel) and notice lag effects.

Week 3–4: Run a tiny experiment
  • Pick one lever (e.g., dinner 90 minutes earlier, phone‑free last hour, earlier light).
  • Track for 10–14 days; compare Then vs Now on sleep/HRV/energy.

Milestone: Ask your AI 3 practical questions about the past week. If the answers help, keep that loop.
