Kvit, the cycle calendar that refuses to fake certainty

Field notes

The product separates forecast provenance into setup answers, recorded cycles, and cases where no reliable calculation is possible. Its privacy explanation says plaintext entries are encrypted before transmission, while the server receives ciphertext and cannot access the device-held key. The homepage also describes a single workflow spanning menstruation, pregnancy, and postpartum tracking, with current and past pregnancy weeks listed as free and future weeks associated with Kvit+.
