Select which data you want to export from your browser's local storage.
This tracker processes your Endfield pull history locally, entirely within your own browser. To use it, you must upload your pull history formatted as a .json file via the Settings tab.
For security and privacy reasons, this site fundamentally rejects and refuses any direct token uploads or gacha URLs. You are solely responsible for extracting your own token and generating the required JSON file. How you choose to extract that data—whether through third-party scripts, packet sniffers, or manual extraction—is entirely up to you.
Once you have securely extracted and saved your pull data locally as a `.json`, simply load it into the tracker to visualize your history.
This project is completely "vibe-coded" using AI without any manual code revision or human debugging. It is currently hosted as a GitHub Page to test the viability of publicly hosting this tool to a wider audience.
You can view the source code and repository here: https://github.com/ram-prices/eftracker.
Use this tool at your own discretion. Because no data is ever sent to a server, your imported history remains private to your device.
