Overview
Itamae is a userscript that lets you extract and preserve your Crunchyroll viewing history. It runs in your browser through a userscript manager and exports your watch data to JSON for local storage.
Installation
Installation takes two steps. First, install Tampermonkey or a similar userscript manager. Then install the Itamae script itself.
How it works
Navigate to your Crunchyroll history page and use the "Load History" button to populate your viewing records automatically, or scroll to the bottom of the page manually. Once your history is loaded, click "Save History" to export your watch data as JSON.
