Lumenspar
A Genshin Impact companion for Linux and Windows
Lumenspar is a free, open-source desktop app (MIT license). It has two tools:
Wish Counter
Pity, guarantees and 50/50 results for every banner, read from your in-game wish history in the same way as paimon.moe. Optionally, the history can be backed up to your own Google Drive, so a reinstall or another computer gets it back.
Inventory Scanner
Reads your artifacts, weapons, characters and materials off the screen
and writes a .GOOD file for Genshin Optimizer, SEELIE.me and
other calculators.
Google Drive backup
Press Sign in with Google on the wish counter page and your wish history is backed up to your own Google Drive, and restored from it on any computer you sign in on. Lumenspar has no server: the backup goes straight from your computer to your Drive. Lumenspar only asks Google for its own hidden app-data folder in your Drive, which cannot see any of your files, and for your email address, to show who is signed in. If you prefer, the app can use a Google Cloud project of your own instead. See the privacy policy.
Web viewer
Once your history is backed up, the Lumenspar viewer shows your pity, 50/50 results and build cards in any browser, phone included. It runs entirely in your browser and reads the backup straight from your Drive.
Download
Releases for Linux (AppImage) and Windows (installer), and the source code, are on GitHub.
