Privacy isn't a checkbox we tick. It's the architecture. Your data lives on your device, encrypted at rest, and never leaves. There is no cloud account because there is no cloud.

What you get on day one

Everything a great tracker should be.
Nothing it should not.

01

Period log

Log flow, symptoms, and pain in seconds. Phase always one glance away.

02

Cycle insights

Length, mood, and symptom patterns over time. No alarms, no shame, no guesswork.

03

Doctor PDF

Export a private, on-device PDF for your appointment. Nothing uploaded to generate it.

04

App lock

Face ID, Touch ID, or PIN at every open. Your data, locked at the door.

05

Stealth mode

Disguised app icon and hidden entries. For when discretion matters.

06

18 languages

All free, all from day one. Cultural translation, not machine output.

Architecturally private

Privacy isn't a setting.
It's the architecture.

Other apps add privacy on top of cloud sync. We removed the cloud. The result is a tracker where breaking the privacy promise would mean breaking the app.

Cycle dates, mood logs, symptom notes. Every byte stays on your phone.
Encrypted with the system secure enclave, the same vault as your Face ID.
No account, no email, no phone number. The app simply opens and works.
Optional encrypted backup ships in V1.5, fully under your control.

What we commit to

Privacy is a structural difference,
not a marketing one.

These are not features we added on top. They are constraints built into how mylune works, which means breaking the privacy promise would mean breaking the app.

Your health data is stored only on your deviceCycle dates, symptoms, moods, and notes are written to encrypted local storage. There is no server copy, because there is no server.
No account, email, or phone numbermylune opens and works with no sign-up. Nothing about you is tied to a login, because there is no login.
We are architecturally unable to read your dataThis is not a policy we could reverse in an update. The app makes no outbound request carrying health data, so we never receive it.
No analytics SDKs, no crash trackers, no telemetrymylune does not phone home. There is no Google Analytics, Mixpanel, Amplitude, or Firebase, and no usage data is collected.
No advertising, no data brokers, everYour health data is never used to profile you or target ads, and is never sold, shared, or licensed to anyone.
Nothing to hand over under subpoenaBecause we hold no copy of your health data, there is nothing for a court order directed at us to compel us to produce.
Where you can get it

Now in USA + India.
Same promise everywhere.

mylune is in early access. We launch where we can deliver the privacy promise without compromise and roll out from there. Same architecture, same numbers, everywhere.

The architecture

Every cycle. Every symptom. Every note.
Stays with you.

mylune's privacy promise is not a marketing line. It is an architectural choice, expressed in four numbers we can never quietly walk back.

About mylune

Health data that belongs to you.

mylune is a women's lifecycle health companion built on a single principle: your cycle, your symptoms, your notes stay on your phone and nowhere else. We built the privacy architecture first, then the product.

🔒

Private by design

Every byte of your health data stays on your device. Not anonymised, not aggregated. Never uploaded. This is not a setting you toggle. It is how mylune is built.

🌍

Built for the world

mylune launches in 18 languages with genuine cultural localisation, not machine translation. We built for India and the USA first because that is where the gap is largest.

❤️

Women-led, mission-driven

We started mylune because period apps kept asking for data they did not need. Our business model is B2B and grants, not your data. Your interests and ours are permanently aligned.
