Shiro has launched My Cup, a personal cup management tool that makes it easy to track your menstrual cup's age, purchase date, and care schedule. Whether you're a first-time cup user or have been using one for years, My Cup gives you a dedicated place to stay on top of your cup's lifecycle.

Getting started takes just a few minutes — a short setup wizard walks you through selecting your cup, entering a purchase date, and setting reminder preferences. From there, Shiro tracks your cup's age and upcoming care milestones for you.

The My Cup section is organized into the following areas:

Overview — A summary of your registered cup, its current age, and upcoming reminders.
My Cup — Full details on your cup, including purchase date and care timeline.
Edit My Cup — Update your cup's details at any time.

Users can register multiple cups, designate a primary cup, archive cups that are no longer in use, and delete entries entirely. It's a flexible system designed to match how real users actually manage their cups over time.

My Cup is available to anyone with a free Shiro account. Once signed in, head to the My Cup section to get started.

Knowing exactly how old your cup is — and when it's time to clean or replace it — brings a new level of confidence and peace of mind to your menstrual care routine.
