Free, no subscription, no account. Connect your own Google Sheet, keep full control of your data, and build lists exactly the way you want.
A quick walkthrough of what the app looks like and how the setup works, before you read anything else.
Mantic's official app is genuinely good if you're running ranked events and need Global Rankings. But if you just play casually — a game here, a game there, no events — a recurring subscription for an army list doesn't make sense. This is built for that second kind of player.

I host the app itself. Everything it reads and writes stays with you — your Sheet, your Google account, your browser. None of it passes through me.
Free, and you copy it in one click. This is your card database — every character, weapon, and rule lives here, editable by you at any time. It stays in your own Drive.
A small free Google service that connects your Sheet to the app. It's included in the Sheet - you just deploy it. Runs under your own Google account, and nobody else touches it.
Your Sheet lives in your Drive. Your Apps Script runs under your Google account. The connection details you type in are saved only in your own browser so you don't have to retype them — they're never sent to me, never stored on any server I run, and I have no way to see them or reach your data. There's no account and no login, so there's nothing for me to hold.
