I have been using BÉPO on my phone since a few years. It is a keyboard layout optimised for French, based on the principle of Dvorak. https://wikiless.org/wiki/BÉPO I still use AZERTY on all my physical keyboards as the switch is much harder, especially with my company or customers ones… The switch from a layout on a phone to a different one on a physical keyboard is transparent.
One simple way to have an idea if an app is not respectful of private data is Exodus Privacy. There are limits as it’s only for Android apps and it won’t alert you that the end-to-end encryption has a flaw or is a plain lie for example. But I think it is a useful resource especially for “non tech” people to have a global idea with just a quick glance, without spending too much time searching for reliable information. In this Stardust case, the MixPanel tracker is cited by Exodus Privacy, among two others. One could then think twice about using this app for sensitive data.
I use Blabber.im but I never tried anything else.

I guess it comes from the French « Système débrouille ». It makes sense in French, though I understand it could be confusing in English for tech people. https://wikiless.org/wiki/System_D?lang=en
