Built on one principle. Privacy first.
mylune is a women's lifecycle health companion where your cycle, symptoms, and 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. It is how mylune is built.
Built for the world
mylune launches in 18 languages with genuine cultural localisation. 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 data has never left this phone. Not once. Not ever.
This is not a policy that could be changed. It is architecture. mylune has no server to send data to, no user database, and no account linked to your health records. We are structurally incapable of seeing, selling, or sharing what you log.
Why we built it
Period apps kept asking for data they did not need - location, contact lists, advertising identifiers. None of it has anything to do with tracking a cycle. The privacy problem in women's health is structural. You cannot fix it with a policy update. You fix it by not collecting the data.
How we sustain it
mylune is free because our revenue comes from B2B partnerships, government programs, and NGO grants - not from selling your data. Your interests and ours are permanently aligned. We have no incentive to harvest, sell, or share anything about you.
Where we launch
USA and India simultaneously - two markets where the need is greatest and no existing app has built the right foundation. 18 languages from day one, with genuine cultural localisation in Tamil, Telugu, Bengali, Marathi, and Hindi.
