Instead of logging cycle start and end dates, fertility tracking requires daily temperature readings, cervical mucus observations, ovulation test results, and sometimes cervical position checks. The data feeds algorithms that identify fertile and infertile windows. The stakes are higher too. People use fertility data to conceive or to avoid conception. Accuracy matters in ways that basic period prediction does not. And the data itself, ovulation timing, sexual activity logs, pregnancy attempts, is among the most intimate health data a person generates.

Temperature entry is manual; you read your thermometer and log the value. Cervical mucus uses categorical descriptions matching standard FAM terminology. OPK results are logged as positive, negative, or peak. The prediction algorithm runs locally o
