I have used Penzu as my main journal app for many years. Recently when Apple launched its Journal app I have been looking at it and other competitors. Then I realized that I am not able to get my own data from Penzu. There is no reasonable Export function. So I found my own way to get my journal data. I could name this blog post to something like “How to export the unexportable”, or “How to intercept XHR requests in Puppeteer”, but my case is about Penzu, so I’ll stick to this particular title.
