I’m a heartbeat from returning to paper records too using a small book with alphabet tabs. There was a time when my phone was more secure than my house, which I rarely locked. But with big tech spying on everyone, my house is now more secure than my phone, so a return to paper is a very good idea.
I would suggest for all to block their web cam, and not to take their phone everywhere with them.....its a tracking device...so is your car probably...I need to buy a burner phone with case this week....maybe three....
