Storing private key in apps and softwares that are local
Storing private key in apps and softwares that are local Im new to butcoin. I installed an app in my phone called Bread. And another in my computer called Electrum. Both of them generated a seed(12 words) for me and it seems that seeed is my private key in the bitcoin network. My question is: these softwares has my private key and i dont know if they stored it in remote servers. This means someone other has my private key and can access my money? This is a safe way in bitcoin culture? They are really local? I want to use safest way to work with bitcoin and i dont want store my info in any website or app that can access my account, delete my account or any other intervention. For safest way should i have my own copy of public ledger in a personal server? What is the safest way? http://ift.tt/2nidhJd
