If you don’t have a government that can be held accountable to some level of trust, then what you have isn’t a government it’s tyranny.
The state has no idea where an umarried person lies on the spectrum from aromantic-asexual to bouncing from orgy to orgy on a daily basis. They don’t know if someone is into BDSM, roleplay, doing it outdoors or threesomes. They also rarely know much about non-sexual hobbies.
Seems naive to me. The question is not whether your government has or can get that kind of information if it wants to (the gestapo had little trouble figuring out things as personal as that without any help from an app) the question is whether your government would lose the cost-benefit analysis if it was ever found to be using such information. You have to hold them accountable and keep their activities in the open so that accessing that information is as close to zero value to them as it can be and they have no incentive to try to get it because people will be able to find out if they do.
“Who watches the watchers?” We all do. At least we’re supposed to. If you don’t trust your government, priority 1 is fix your government, you’re way beyond anything a dating app’s data can be expected to help with. You’re not going to be any safer from an unaccountable government because you denied them access to a dating app.
