If I update it will it save progress?

If you update the game it shouldn't affect your game data. If you are wanting to save your game progress over all in case you delete the game or it gets deleted some how in the future but want to recover or get your game data back you would have to make a account which is free, and will allow you to save your game data which you can recover at anytime or you can use the account to swap to another device just be sure to write down your master code, and use your real email. A lot of people used fake ones, and lived to regret it with your real email worse case you can recover your master key there, and you need the keys to redownload your save data for anything. Also please don't share your keys, and account information as it can cause you to lose your account more then likely a lot of people over the past years have been broken up about it, and had to start all over. I've met some that's restarted from two to eight or more times because of one issue or another which I'm still amazed they feel like starting over from scratch, and amazed by them since I don't think I could do it personally.
