Research participation

Join the movement for women’s brain health.

Women’s brain health has been under-researched for too long. Leni can help build a more complete picture of what women actually experience across life stages — from reproductive years to perimenopause, menopause, and healthy aging.

Always optional

Opting into research can help Leni better support women’s brain health.

With your clear consent, the information you choose to share can help advance ethical, privacy-protected research into the patterns that shape women’s brains and lives.

Participation is always optional. You can use Leni without contributing to research, and if you do choose to participate, your data is handled with clear privacy safeguards, transparency, and respect.

Together, we can ask better questions, close long-standing gaps, and build better care for women.

Privacy + ethics

Research should feel clear, consent-based, and respectful.

Consent comes first

Research participation is optional, separate from using Leni, and based on clear consent.

Clear data use

Leni will be clear about what is collected, how it may be used, who may access it, and how participants can withdraw.

Careful research practices

Any research use of health information will follow applicable privacy laws, ethical review requirements, and HIPAA-aligned safeguards where applicable.
