Where is my data stored in Cardstashr?

Cardstashr stores all your collection data locally in your Chrome browser using chrome.storage.local. Your Cardstashr trading card data never leaves your device. There is no account, no cloud sync, and no server-side storage of your personal collection information.

1Local Chrome Browser Storage for All Card Data

All binder data, card positions, custom tags, and settings are saved in Chrome's local extension storage on your computer.

2Persistent Collection Data Across Browser Sessions

Your Cardstashr data persists between browser sessions. Close Chrome and reopen the extension and everything is exactly where you left it.

3No Account or Cloud Sync Required for Cardstashr

Cardstashr does not require any login or account creation. All data lives locally in your Chrome browser profile with no external dependencies.

4Backup Your Cardstashr Data with JSON Export

Use the Export feature in settings to back up your entire collection as a JSON file. This is your safeguard against browser resets or Chrome reinstalls.

Cardstashr's local-first storage approach means your trading card collection data is private and always accessible. Export regularly to keep a backup of your binders and all extension data.
