Here are the note apps tuta recommends. Also, fyi, standard notes was recently acquired by proton. Some view that as a positive, I personally think proton is becoming too big a honey pot now that they offer so many services under one umbrella/account 
How many people use https://standardnotes.com as their note taking application? It has some pretty great features.
You have the option to sign up anonymously without a email.
It is cross platform and syncing.
The notes are stored on their servers in the US which is not ideal but the notes are e2ee, even the meta data.
Plus an option to encrypt on the device.
Anyone use it?

Trusting Proton so much is not a good idea. Obsidian is not open source and anything else than Keepass means your secrets are in someone else's PC
