For secure devices, I recommend a GrapheneOS base OS with no google apps tracking you. I would then install Briar instead of session and openpgp. and tor/i2p. I would then install Bote I2P app for email and install Kmail and configure i2p then import your PGP keys.
Now do this to 4 devices, and synchronise the keys and accounts.
Communicate Private over I2P Email/PGP or TOR Briar.
What do you recommend ?
Avoid Voice Communications if possible.
