Cycle health,
sovereign and shared

Ovulate is a cycle-tracking and symptothermal platform designed for women, couples and the professionals who support them — with one absolute requirement: your health data stays in Europe, under your control.

The project

Understanding your body, together, with confidence

Ovulate was born from one conviction: cycle tracking should be neither a mental load carried by one person alone, nor a commodity monetised by foreign actors.

Mental load, shared

Cycle tracking concerns both partners. Ovulate enables simple, consent-based sharing of observations within the couple, so everyone can take part in the household's reproductive health.

Sovereignty by design

Health data under Article 9 of the GDPR: Ovulate relies exclusively on HDS-certified European infrastructure, out of reach of extraterritorial legislation (Cloud Act, FISA).

Symptothermal method, taken seriously

Basal temperature, cervical mucus observation, peak day: Ovulate supports a recognised method with scientific rigour, and is preparing for connected temperature sensors.

Our expertise

Midwife expertise, in service of your observation.

Ovulate builds on the principles of the symptothermal method, a scientifically documented approach to cycle observation with decades of research behind it. Its implementation is validated by midwife expertise, guaranteeing the rigour of every reading rule.

Two independent indicators — temperature and cervical observation — confirm each other before any conclusion about your fertile window. This double check is what separates a rigorous observation method from a simple average-based calculation.
