Luminara
Light you can keep.
Your whole self, in one place — and only yours.
The problem
Your health is scattered.
And it's being watched.
Your cycle in one app. Labs in a hospital portal. Meds on a sticky note. Postpartum feelings — nowhere. And every tap is quietly sold to advertisers.
Life before Luminara
Track in five apps,
or trust none of them.
The usual
✕ Cycle, labs, meds, mood — four apps that never talk
✕ Your most private data lives on someone else's server
✕ Postpartum depression? No app is even looking
✕ One algorithm for everybody — built for nobody
With Luminara
✓ Cycle, labs, records, meds & mood in one thread
✓ Encrypted on your device — nothing to subpoena
✓ A real postpartum check-in that watches for the dip
✓ Guidance tuned to your body, your background, you
The Luminara way
Every signal.
One light.
- Cycle, biomarkers, labs, records, meds & mood — one connected story
- A wellness read that blends your cycle phase, labs and check-ins
- Private by design — it lives on your phone, encrypted, not in a data lake
Say it in one breath
Your body.
Your data.
Light you can keep.
Now — the design
One idea,
drawn everywhere.
A candle in the dark: warmth for the hard hours, light to see by, and a flame you hold close — never a beam you broadcast. That single image is the whole system.
The logo · why
A single flame,
kept in a cradle.
- Warmth: a companion for 3am feeds and hard postpartum nights
- Clarity: it turns scattered data into something you can see by
- Held: the cradle says protected, private, on your device
- No clouds (that's the thing we're not), no candle for a vigil
The logo · how it lives in the app
One flame,
coloured by your phase.
The same flame everywhere — the phase strip, the check-in seal, the partner dot, the app icon — it just takes the colour of where you are today.
The design · colour
Calm indigo to trust.
A flame to warm it.
Indigo carries the calm and the credibility. The warm flame is rationed — it appears only to guide, so when it glows, it means something.
The curves · why
No hard edges
on a tender day.
- Why: a sharp corner is a form; cupped hands are a place to rest
- How: the same rounded family — flame, cradle, pill, card — 16px radius everywhere
- Every screen breathes on a slow, unhurried rhythm
The design · one system
The UI is
the promise.
- Lavender canvas, calm as a quiet room
- Consent switches are visible, honest, and never dark-patterned
- Every claim reads "not a diagnosis — talk to your provider"
The Luminara promise
Private by design. Yours by default.
Encrypted on your device. Nothing leaves unless you choose to share it — and then only anonymised.
Part two
The market —
and where we win.
Menstrual-health apps are a $2.4B+ market split into six battlegrounds. Here's every serious player, and the exact gap Luminara is built to own.
The landscape
Six battlegrounds.
One unclaimed corner.
Flo · Glow
77M+ users, AI chatbots, community. Growth over privacy — and they sell reach.
Clue · Natural Cycles
Clinical credibility & GDPR. NC is FDA-cleared contraception. Cycle-only focus.
Apple · Fitbit · Ava
Free, wearable-fed temperature & sleep. Thin on records, labs, mood.
Euki · Drip
On-device, zero cloud, un-subpoenable. But shallow — cycle notes, little depth.
Premom · Fertility Friend
LH-strip scanning, chart-reading. Laser-focused on conception only.
Stardust · Ovia · Samphire
Gen-Z aesthetics, employer B2B, neuro-wearables. None own postpartum.
Where everyone sits
Privacy × whole-person
depth.
The whole-person + private corner is empty. The privacy apps stay shallow; the deep apps sell your data. We're the only one going deep and staying on-device.

The moat
Why Luminara wins.
- Whole-person, not one organ: cycle, labs, records, meds and mood live in one thread — everyone else tracks a slice.
- Privacy without the shallow tax: Euki-grade on-device encryption, but with the depth Euki lacks. You don't trade safety for features.
- Postpartum is our wedge: a real PPD check-in with a risk model — the one life stage no giant is even looking at.
- A partner, by consent: PIN-gated co-observation for the weeks when someone else notices the dip first. Nobody else has it.
- Care that sees you: ancestry-aware, non-diagnostic nudges (vitamin D, thalassemia & sickle-cell, fibroids, gestational diabetes) — health equity built in, not bolted on.
- Honest by policy: no fake HIPAA badges, no dark patterns, "not a diagnosis" everywhere.
To pull further ahead
What we build next.
Wearable & HealthKit import
Pull wrist-temp, HRV & sleep from Apple Watch / Oura to auto-feed BBT and the wellness score — matching Natural Cycles & Ava.
E2E-encrypted multi-device sync
The SyncAdapter is already stubbed — ship encrypted-blob sync so data spans phone + tablet without a server ever seeing plaintext.
On-device AI companion
A postpartum-aware assistant that answers privately, on the phone — Flo's chatbot without shipping your questions to a cloud.
Camera LH / test-strip reader
Scan ovulation & pregnancy strips into a numeric curve — beating Premom at TTC, inside a private app.
PCOS · PMDD · endo tracks
Dedicated symptom tracks for the conditions the mass-market giants flatten into "irregular."
Arabic / RTL & SWANA-first
Localise the equity library and UI — own a region the incumbents ignore.
Clinician one-pager export
generateReport already ships — polish it into a share-to-provider PDF and a subpoena-proof local vault.
Pursue FDA fertility clearance
Formalise the BBT model into a cleared fertility-awareness mode — Natural Cycles' one true edge, neutralised.
