While most keyboards have millions of downloads, this keyboard only has a thousand downloads, but I use & love the open source OpenBoard keyboard.
a. It's free, ad free and gsf spyware free
b. It's open source & it says it follows EU privacy rules
c. It has a mic button so I use it often with the speech-to-text

OpenBoard valencia <=== I just added this moments ago

Apparently OpenBoard valencia is "derived" from dslul OpenBoard.
"OpenBoard valencia is a 100% FOSS keyboard (free software and
open source code) based on AOSP, without dependencies on Google binaries,
respecting privacy law. Derived from the original OpenBoard to include
the prediction for the valence following the spelling regulations
of the Normes d'El Puig." <http://www.softwarevalencia.com/>

I'm not sure why the dslul OpenBoard is no longer on the Google Play Store repository - but I'm sure you can get it from GitHub so it won't matter.
