This looks great! From the screenshots, it looks like a nice, clean, thoughtful design. I would love to use it if I could run it myself. The app needs some pretty private data, and I would hate to lose it all in the middle of a job hunt if you decided to shutter it.
Would you consider making it OSS? I would happily donate toward that end. I can also offer to help package this app for the Sandstorm.io platform (OSS, https://sandstorm.io). Sandstorm enables one-click installs of server apps on self-hosted and managed servers, with great security and privacy out of the box. It will also serve as a marketing platform and channel for future donations for your app. Since Job Search Sanity is basically a private single-user cloud app, packaging it for Sandstorm should be very straightforward.
