Private cycle journal

HerPhase

HerPhase keeps daily check-ins, notes, and logged-cycle timing estimates together. The free-first version stores entries locally, has no account or app-managed cloud sync, and uses no analytics or tracking SDKs.

Private by default

HerPhase stores cycle settings, daily check-ins, moods, physical tags, and notes locally in the free-first version. Device backups and transfers follow your operating-system settings.

Built for reflection

HerPhase maps the dates and cycle length you enter to an estimated phase and summarizes only the check-ins you log.

Wellness only

HerPhase is not medical advice, diagnosis, contraception, or a fertility tool. It provides general wellness information.
