How do I get feedback from existing daily active users?

I kept the basics usable without an account or email signup because privacy matters to me. These will be added once I add features that costs me to run the app and hopefully add a subscription later-on.

These are the reasons I don't have a direct way to reach out to the users. Although there's feedback section and a way to directly reach out to me through Discord.

It's a windows desktop app, what are some ways I can engage with the users?
