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.


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.


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.


This app is free to download but requires a free Penzu account in order to start writing.

Upgrading to Penzu Pro costs $4.99 per month or $19.99 per year. Your subscription will auto-renew unless you cancel manually.

As a Penzu (premium) user for years, I love being able to jot down notes in the app when I am away from my laptop. However, I switched phones this year and now the app won't let me see journal entries or add new ones, it just remains stuck on the "loading" screen. I've tried uninstalling and luck.

I use this app with the desktop browser version. I started with the free version, journaling & jotting writing ideas on the go. App syncs beautifully with desktop with a quick page refresh. I haven't lost progress. I eventually upgraded for encryption & multiple journals. I love autosave feature. Great experience. Happy with this choice :) Love ability to lock journals: check journal settings to set autolock features if this is something you don't want. I find it helpful.

I really wanted to love this app. I have used it for long time for journaling. I liked that it was simple and pretty basic. I also liked that I could have it on two of my devices so that it would be link. However, I have found that it won't always sync. It also doesn't allow me to copy and paste . That is really a pain.I have had the journal close on me and not save and have lost everything I have written. Please fix these bugs. It is so frustrating. I am looking for something better.
