My rewards.I deleted Brave, did I lose my rewards?

Good Morning. I uninstalled my Brave and I had some rewards. I didn’t transfer them to GEMINI or my wallet. When I reinstalled they were no longer there. My question is: Have I missed these values ​​from my reward?

Yes. Since you had not transferred/connected to a custodial account, the rewards were stored on your Brave’s Local files which were deleted when you uninstalled Brave.
