This is not a direct solution to your question. The only available option currently is Florisboard. I tried it but it didn’t work well for me. Ever since I’ve justbeen using openboard. Clean, fast, pretty accurate but no glide typing. There is an open issue for it and some POC work had been done but not merged into main.
All big tech analyzes our data. I rather they not analyze anything but since we’ll never see that day, they can at least use their privacy invasion power for good.
