Privacy Policy

This policy explains what information TB Toolkit uses and where that information is stored.

Effective September 1, 2026

Information TB Toolkit does not request

TB Toolkit does not require an account, subscription, or payment. The site does not ask for your name, email address, game login, or payment information. TB Toolkit does not use advertising trackers or its own analytics service.

Calculator data

Information saved on your device

The Battle Calculator saves Player Accounts, encounters, selections, calculator inputs, and optimization results in your browser's local storage. This information stays on your device and is not uploaded to TB Toolkit.

You can remove this information by clearing the site data for TB Toolkit in your browser. Removing browser data can erase your saved calculator information.

Account transfer

.biff files

When you export a .biff file, your browser creates the file on your device. When you import a .biff file, your browser reads and validates the file on your device. TB Toolkit does not upload the file to a server.

A .biff file can contain the Player Account name, custom encounters, saved workspaces, selections, and calculator inputs that you chose to export. Keep exported files in a location that you trust.

Service operation

Hosting and technical records

The service provider that delivers this website may process standard request information, such as an IP address, browser type, requested page, date, and time. This information may be used to deliver the site, maintain security, and diagnose technical problems. TB Toolkit does not combine these records with calculator data stored in your browser.

Third-party content

Google Calendar

The Event Calendar page contains an embedded Google Calendar. When that page loads, your browser connects to Google. Google may receive technical information and may use cookies or similar storage according to its own policies.

You can review the Google Privacy Policy. TB Toolkit does not control Google's information practices.

External websites

Third-party links
