Ads count is reset when using Deep Freeze

Hi support team,
I’ve come to an issue and need your help/ clarification.
I am using Deep Freeze in my desktop, so whenever I restart my computer, all my files remain the same. So my children can not install new games or harmful files on my computer.
However, the software also reset the ads count back. More specific, I have ~40 ad notifications received Until today, then after restarting my computer, the browser set back to ~20 ad nortifications which is at the point I started using Deep Freeze.
I was believing that information of ad count is stored on Brave server, not in my computer. So that I can use Deep Freeze without losing ad count.
Could you guys please clarify and help me solve this issue.
Thank you very much and have a great day.

please? any solution?
