Is this some dark pattern or what?

I clicked settings, this appeared, clicking away hid it but now I cant see any setting for it.

The nasty way of reading that popup, my first way of reading it, was that filestash sends crash reports and usage data, and I have the option to have it not be shared with third parties, but that it is always sent, and it defaults to sharing with third parties. The OK is always consenting to share crash reports and usage.

I'm not sure if it's actually operating that way, but if it's not the language should probably be

    Help make this software better by sending crash reports and anonymous usage statistics.

    Your data is never shared with a third party.
