I use anysoftkeyboard which I think you can get on Google’s app store and the open source stores like F-droid.

It has it’s quirks like the keyboard layout on every phone I use it on is different and I can’t make them the same. The app is a mess to navigate as well.

But it supports swiping and it’s private. I was using Swiftkey previously, it was great, but now it’s Microsoft and they’re pushing their AI shit in the app
