I have successfully canceled my memento database subscription.

I subscribe to that service for my personal item tracking (or personal inventory management), at that time I need an Android app to scan barcode, and it works well.

As a cutting spend operation, now I save 60USD per year (or 80USD with the new plan with AI™) with my own software.

Introducing jim-cli: It's a command line tool for managing your inventory. Basic CRUD, tag system, keyword search with highlighting. Not very complicated, but good to me.

And to work on Android, I designed an encrypted API for LAN HTTP based on the pre-sharded key. I can run it when I need it, and save the server fee in the rest of the year. (I only need it around Feb and Oct)

You can have a look on github.
