Menstrual Cycle Tracking Apps

Period tracking apps have become part of many people's routines: keeping tabs on menstruation, symptoms, or fertility can be genuinely useful for your health. The most popular ones offer polished interfaces, appealing graphs, and increasingly precise prediction promises. But every piece of data you enter — dates, flow, pain levels, sexual activity, pregnancy intentions — ends up in the hands of companies that live off targeted advertising. According to Mozilla's Privacy Not Included report, most of these apps don't even meet basic security standards; your intimate data is aggregated, profiled, and sold.

The alternatives in our list are open source and often designed to work locally, free from trackers and advertising: they treat your phone like a personal diary, not a data mine. They're often less polished visually, some are only available in English, others lack contraception alerts or password protection. If you want a highly curated experience with intrusive notifications, these apps will feel bare-bones; if you want to keep your reproductive health out of the data market, they do exactly what's needed.

We're always looking for people who can try out new applications — if you'd like to contribute, don't hesitate to get in touch.
