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.

Excellent for my day to day random thoughts, and I really like the ability to create multiple journals for different reasons. I have one for rambling, 1 as a dream journal, one that is LOCKED for private thoughts, the possibilities are endless...I might create one for favorite recipes. I have had no problems with ads, and the app is so easy to use.

I love having a safe space to reflect & release, my ability to have more than one journal and the convenience of being able to type it out or speak it out when unable to hand wrote it out. Journaling has always meant a lot to me. I found this app after privacy was invaded with my journals and I lost consistency with writing. Having a password protection helped me dive right back in to what works best for me!

Glitches without end. I've lost entire journal entries because of the app malfunctioning. When I write from the website, each time I hit enter shows up as giant gaps between paragraphs in the app. Now I can't upload pictures on the app because it shows up as Not Found. I've deleted the app data and reinstalled and restarted my phone more times than I count. I'm only continuing my use of Penzu because I've had the same journal for years, but this is exhausting.
