If you mean the servers you could use something open source like bitwarden and just not use their online service, you can host your own server or use it locally.

Have you tried looking on itch.io? I recently got a few games from there (some are hosted on the play store but not all)

Only bad thing about browsing is that 80% of the games seem to be dating sims or visual novels (which is fine if you’re looking for that, but annoying if you’re not)

Edit: infidhells seems really fun, but haven’t had time to play much, to use all the gameplay features it’s worth playing with the sound on (though it has accessibility options for playing without audio).

To some extent I can understand it, it’s very normal to have both of those things just for the sake of it in today’s media, to that guy it might look even more rampant than to you and I.

Similarly, I personally like manga/anime but kinda hate how fanservice gets inserted with little to no consideration on how it affects a scene (and it seems to happen in most works aimed at a male demographic, can’t speak for all genres), if I want to see some actual skin I can always look up porn.
