This is the perfect journaling app

This app is exactly what I was looking for. There's no account to be made, so my journal entries cannot be tied back to my email address. It is completely private and safe. The decoy password is the best feature, and this is coming from someone who lives in a strict household. I love to journal and need a place all to myself where I can write my thoughts. A physical is not fully safe and anyone could just go through it or force me to tell the password. Anyway, this app gives me a fully secure sense of safety and privacy. It is especially efficient because I can write whenever I want on my phone.
