Hi, CEO of Rainway here.
You actually don’t need to sign up for Discord, emailing support@rainway.com is enough. You can also close your account from the app.
Discord is a convenient medium since our audience largely engages with us through it daily. I’ll update the article to reflect all the valid options.
And to be clear, our business model isn’t in data nor do we share data with others. Outside of basic engagement telemetry we don’t even know what games you own.
