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

The app is good. I don't like the automatic copying (of the first sentence) feature in the automatic recall. This is a journal therefore I'd like to keep everything private. Furthermore when traveling across multiple time zones, the streak gets lost. Recently, I traveled from east coast of US to Asia with 13 hour time difference, my streak was okay going over but completely lost coming back. This to me is the most annoying part of this app.

I love it. It would be nice to have more features in the paid version (which I have). In the past, we could choose inside of each journal (example: lined, unlined, etc). I like how we can have multiple journals (keeps me organized). Even if you delete the app, as long as the account is open, all is saved. I just love it. Thank you!

I'm a long time Pro paid subscriber. The glitches of this app are becoming absurd and infuriating. I'll write an entry and trust that it's being saved automatically (since on the app there's no separate "save" button) only to back to come back to an empty screen where only the first line was saved. This has happened dozens of times and I no longer trust the app. Which is too bad because a simple journaling app that syncs between devices is all I need and it should not be this difficult to make.
