The need
Most girls meet their first period without the facts.
11%of schoolgirls surveyed had good knowledge of menstruation.
34.9%had missed school because of their period.
63.6%learned about periods mainly from their mothers, who often lack the facts too.
Study of schoolgirls in Kisangani, DRC. Pan African Medical Journal, 2025.
Ma Lune
A private friend on the phone families already use.
Short, kind messages that answer the questions girls are too shy to ask, prepared with a gynaecologist and written for girls in the DRC.
Period calculator
Girls note their dates and Ma Lune estimates when the next period will come.
A real person when it matters
Words about violence, abuse or heavy bleeding alert our team, and a trained person replies in private.
A space for parents
Seven lessons to help mothers and fathers talk about puberty, questions about sex and the first gynaecology visit.
Quiz and feedback
A short quiz before and after the lessons shows what girls have learned.
Private by design
Consent first, a nickname only, and girls can ask us to delete their information at any time.

Your rights
You can ask to see, correct or delete your information, or withdraw your consent. Write SUPPRIMER in the chat or email info@zuthero.com. If you are not satisfied with our answer, you can complain to the Information Regulator of South Africa.

Free service
Ma Lune is free. Your mobile network may charge for data. We may change, pause or end the service, and we will tell users in the chat when we can.
Respectful use
Do not send insults, threats, sexual content or other people's personal information. We may stop replying to anyone who misuses the service.
Content
Ma Lune's health content is shared under the Creative Commons Attribution-ShareAlike 4.0 licence (CC BY-SA 4.0), and its conversation flows under the MIT licence. The Ma Lune and Zuthero names and logos remain ours.
Responsibility
We work to keep the information accurate and up to date, but we cannot guarantee that it fits every person's situation. To the extent the law allows, we are not liable for decisions made only on the basis of Ma Lune's messages.
Law
These terms are governed by the laws of South Africa. Questions: info@zuthero.com.
