> My startup is helping to tackle this problem by trying to inform people that menstrual cycle data, on its own, can help prevent pregnancy with the same efficacy as hormonal contraception (and this isn't the rhythm method, despite the common misconception).
I think you should be very careful with making unqualified statements like that. If it isn't the rhythm method then you should explain exactly what it is because the 'common misconception' requiring you to distance yourself from the rhythm method before someone even brings it up is alive and kicking and it is up to you to provide the evidence that it isn't so by explaining how it does work.
Your marketing video certainly does nothing to clarify, and the app description on your website screams 'rhythm method in an app' from every page.
