I like this website :)

Reviewed on 2021-02-06T23:03:05

I'm sick of my mom sneaking into my room, and reading my diary without permission. After she reads it,she tells it to everyone. I was really mad at her, and wanted to find a way to write in my diary without her reading it. A week later, I found penzu!! I really liked how it has a password instead of a lock. My mom didn't find out about my secrets after I signed up to Penzu. Thank you so much Penzu!!! I love that site!!!
