WHY PENZU?
Penzu is a diary and personal journal that is focused on privacy. With a unique and compelling user experience, it makes writing online as easy and intuitive as writing on a pad of paper.
PRIVACY
Your journal and your thoughts aren’t always meant to be shared — some things are supposed to be private! Use Penzu to jot down whatever you want. Then lock your journal with a password (or even encryption) so no one can read it but you! Furthermore, you can lock the entire app with a PIN in the event that someone gets access to your mobile device.
PENZU
Unlike other journal apps, Penzu has a web-based counterpart. So you can access your journals and diary from any web browser and other devices. Penzu is constantly being updated and improved so that the writing experience is effortless and reliable.
SUBSCRIPTION INFO
This app is free to download but requires a free Penzu account in order to start writing.
Upgrading to Penzu Pro is available for a small monthly or yearly subscription. Your subscription will auto-renew unless you cancel manually. Monthly subscriptions are $4.99 USD and renew every month. Yearly subscriptions are $19.99 USD and renew every year.
