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 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.

Awful experience!

I downloaded Penzu and started by using the free version; I was needing to find a nice solid personal journal app for medical reasons. It was so pretty and easy to use, loving all the great features of the free version. So I'd decided it was the perfect app for my needs and had decided to begin a subscription--but before I took the time to do so, something happened when I was using it and EVERYTHING was erased. All my hard work! It happened when I was in a rush to close the app and a pop-up box appeared. I obviously misread it and, with one tap, erased my entire journal. I ran and checked the app on my Mac, and I checked via the browser version--but everything had already synced to total deletion, total nothing. Obviously I should have been paying more attention to this random, single pop-up box, but how can a journaling app allow for everything disappear so easily? I contacted Support and it took almost two weeks for them to respond (it was over the holidays)--only to have them tell me that there was no journal in my account, or rather, that I had not created a journal.

Morals of the story: find a journaling app that doesn't let complete deletion happen so easily (!!!) and back it up (paid version only with Penzu), and don't expect Penzu's customer service to treat you like a human being under the age of 100 who knows how to use technology.

Great journal app with a few issues

So Penzu has been my go-to journal application for almost half a year now. I have used journals and electronic journals before, but this is my first one that is online. The syncing works moderately consistently, but there are times where the program takes a while to save after copying in a sentence or two. Also, the app crashes when pressing the add photo button- probably just a version bug, but still. I don't want to have to put my photos on my computer just to put them into my journal. Plus, Penzu does not really seem optimized for photos at all. You cannot edit them, or move them easily. They go in a line, and do not have a function to wrap text. Penzu, get on that. I want to be able to use photos more. Also, please let gifs move. Thank you. You can use Penzu for free, and almost all of the functionality is there. You can get reminders even with free. In Pro though, these reminders can be set to custom times and you can change the cover of the journal to be anything you want, not limited by the few free choices that they have.


First of all, you aren't even allowed to log in or use the app unless you pay for Penzu's premium service. I actually do pay for premium service, so I downloaded the app and have tried to use it on several occasions. The issue is that - regardless of the fact that I am connected to Wifi AND have a healthy number of 4G data bars - the app doesn't save my entries as I type. This has happened on more than one occasion. Just now, I was trying to type a fairly long entry. I was almost done when my husband came in the room to ask a question. I put my phone to sleep (without exiting the app) so I could give him my full attention. When our conversation was over and I woke my phone up to continue typing, I saw that more than half of what I'd typed was no longer there. I nearly cried! I don't see the point of an app that 1) probably less than half of your customers can even use, due to the premium restriction, and 2) that doesn't save things in a timely manner. I'll stick with Google Docs from now on when I want to type something because I know it saves everything each second that I'm connected to the web.
