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.
Architecturally privatePrivacy isn't a setting.
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.

The architectureEvery cycle. Every symptom. Every note.
Every cycle. Every symptom. Every note.

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.
