I personally have some trouble trusting apps with such personal information about myself. It's one thing to put in your email and phone number, or even credit card, but it's entirely different to put in all of your most private thoughts, feelings, and emotions.
You never know what the apps company does with this information. I can understand the positives and benefits of journaling with an app, especially if they can sort of analyze the journal entries and show you information such as things that trigger you or things that cause you stress, or other insightful things, but even with this, I still could not feel comfortable with it.
Journaling for me is probably the most private thing I can do, it's the most private time of my life that I do not share with anyone, nor do I want to. So having all of the things I write, on my phone, in an app, on the internet, is just not something I would even consider. Even if it's not on the internet, the fact that it is on a phone, or digital device that is hackable, is just not something I would be comfortable with.
