Your health notes, kept close.

A calendar and observation log for this browser. Saving is off until you enable it. You control every entry, backup and deletion; there is no account sync or automatic medical interpretation.

Your observations, at your pace.

Keep a calendar of periods, weight, temperature, movement and hydration. You choose what to record. This tracker shows observations; it does not diagnose conditions or confirm ovulation.

Saving is off by default. If you enable it, observations stay in this browser profile on this device. They are not encrypted or synced to an account, and other people using the same browser profile may see them.

Private browsing, clearing site data or changing devices can remove your records. Export a copy if you want to keep one.
