CozyFlow App

Turn every cup empty
into cycle insight.

Each cup-empty moment becomes a quiet clue: your flow, body rhythm, and care needs gathered privately so your cycle starts to make more sense.

1Empty

Use CozyLeaf as usual. The logging moment is already built into real cup care.

2Log

Tap time, flow feel, symptoms, or body rhythm without measuring milliliters.

3Notice

See cycle, fertility, partner-support, and FeelVu context without public raw notes.

01

Real-use flow signals

Start with the moment CozyLeaf already creates: each cup empty. No pad guessing, no milliliter math required.

02

Body-rhythm context

Add symptoms, sleep, stress, movement, food rhythm, and body signals so flow changes sit beside the rest of your day.

03

Opt-in care sharing

Partner and FeelVu layers use derived care windows only. Raw notes, bleeding details, and health history stay private unless you choose otherwise.

CozyFlow is educational, not diagnosis, treatment, contraception, or fertility advice.It helps you notice personal patterns and decide what is worth tracking next.

01 — The thesis

Many beginners give up too soon.

Not because cups are wrong. Because the design assumes you'll figure it out.

02 — The four

Four moments,
rebuilt.

The reasons most beginners quit aren't mysterious. They're predictable.

01 Insertion
Patented
Insertion

Opens like an umbrella.

No squeezing, folding, or guessing. Unfolds intuitively — the way your hands already know how to do it.

02 Sealing
Patented
Sealing

A seal you can feel.

Elastic tension plus an air channel form a stable seal — with clear tactile feedback, not a guessing game.

03 Discharge
Category first
Discharge

Empty without removing.

A first in this category. Discharge without full removal — for offices, planes, and public bathrooms.

04 Removal
Patented
Removal

Releases gently.

Suction breaks with a soft, controlled motion. No pulling, no panic — just a calm, quiet exit.

03 — The object
Patent granted ✦Cozyleaf as object

Designed for the moments
cups get wrong.

A patented menstrual cup concept focused on calmer insertion, sealing, discharge, and removal. Built around the parts that often make beginners hesitate.

05 — More than a cup

More than
a cup.

A better experience is the wedge. The mission is wider.

— 01 Environment

Less to throw away.

The average person uses over 11,000 disposable period products in their lifetime. Most take 500–800 years to break down. A single reusable cup replaces up to a decade of disposables — same cycle, a fraction of the waste.

— 02 Access

Period care isn't a luxury.

500 million people globally lack access to adequate period care. Missing school. Missing work. Managing in silence. A reusable cup costs less than two months of disposables — and lasts years.

06 — The list

Be first when
it clicks.

First in line for launch pricing and founder updates. No spam, no noise.

Be among the first to know.
