Where does Alice's voice assistant save reminders (in hardware)?

Question

Calendar

Today I bought a JBL speaker in the DNS chain of stores and received a device as a gift - voice assistant Alice (DEXP SMARTBOX).
After setting up, I tried to set reminders. Everything was installed, BUT ....
1. These reminders are not visible in the Yandex calendar.
2. In the calendar on the phone from which the voice assistant was configured, these reminders are not visible.
At the same time, synchronization between the Yandex.calendar and the phone is configured.
Accordingly, the questions are:
1. Where does Alice's voice assistant save reminders?
2. Is it possible to make sure that they are saved to the calendar (any, Yandex or Google - it doesn't matter, they are synchronized)?
3. Is it possible for events from the calendar to be announced by the device on its own (without the command - announce events)

Answer 1

Alice saves notes not only locally

Or in the Yandex calendar, click the checkbox icon in the upper right corner
