Heliboard is what you seek.

FlorisBoard and FUTO both don't require network permission IIRC. I used to use FlorisBoard and then moved onto FUTO because it had swipe keyboard and better Korean and Japanese support.

Maybe Fossify and HeliBoard?

For me, Heliboard is the best option. FlorisBoard is cool too if you like their interface, but Heliboard is super customisable. You can change the symbols around, padding, colours, etc., and it supports plenty of languages and can work well with Whisper for TTS, and the auto complete suggestions is quite accurate in my experience. You can also change the toolbar to include copy paste, undo and redo, left/right, etc.

Heliboard also has glide typing, which requires the installation of a proprietary library, which I just tried out and it works really well! There's also a tab to "train" the glide typing so that the Heliboard team can help develop a fully FOSS library (basically, it gives you words and you glide type. It's like an opt-in quiz)

futo keyboard has been great. bonus points for being able to swipe with two fingers simultaneously

FlorisBoard and HeliBoatd. Both available in F-Droid. Both are excellent. I lean toward HeliBoard but will switch between them occasionally.

thumb-key by one of the creators of Lemmy. It's also very lightweight and snappy.

It took me a few days to learn though. Now it has become my 2nd nature. I type fast and effortlessly with it. I don't even look at the keyboard anymore while typing.

Unexpected Keyboard is my recommendation. Now that im used to it, everything else feels slow. You swipe the corner to get the alt/symbol/capital, so much faster than holding a keypress, even for 1 second. Very customizable.

I liked heliboard. It doesn't require network access, has gesture typing that works well, though you have to manually add the library, lots of configuration, and some stuff I use all the time like slide on delete to choose how much to delete and slide on space to move cursor.

Basically it is both private and a pleasure to use (after configuring)

I tried a bunch to replace what wa the default which is something google stuff I guess and they all behaved very weird or didn't feel right. After configuring a bit I finally made HeliBoard work well enough. I like it.

There's just a really fucking weird thing that is making me maybe look for something else: when there's a typo in an input and pressing on the red squiggle if opens an horrible popup which I have no idea how to turn off and I tried everything.

Not really sure if it makes internet calls, but really hope not.

For looks, customized it enough to look basically the same I had before.

Question, how much is being stolen using stock Samsung or google keyboards?

I also use heliboard.

Right now I'm fucking with OpenBoard, it's alright. I'm watching Florisboard for the day they finally implement glide typing again

I use HeliBoard. It's fine, but I don't have any special use-cases/needs; I just wanted a normal keyboard, which HeliBoard is fine at. If you have anything specific you need, I'm not sure if HB does it.

I use the fossify one, its everything I need. No permissions and can show clipboard and delete with ease. Only thing I hate is that the standard keyboard remains an option and loads in with a mis touch nut thatnisnt the apps fault.

Thumb key is the best for me. Its awesome once u learn the basics. Give it a try!

Maybe I've overlooked it, but I haven't seen https://f-droid.org/packages/juloo.keyboard2 mentioned so far.

I use one called Urik Keyboard. Words turn red when you misspell something, its an interesting keyboard, still getting used to it.
