Privacy policy

Last updated: October 2026. This page describes how the Breadbit software handles data.

What stays on your device

Your circuits, notes, activity history, theme and other preferences are stored in your browser’s local storage. They are not uploaded unless you sign in to an account. Clearing your browser data removes them, so use the library export to keep a backup.

If you create an account

Signing in is optional. When you do, authentication is handled by Google Firebase Authentication, which processes your email address and password (or Google sign-in details). Your saved circuits and theme choice are then stored in Google Cloud Firestore, linked to your account, and are readable only by you. You can delete circuits at any time from the library, and you can ask for your account to be deleted using the support form.

Support messages and ratings

If you send a support message or a rating, we store what you write, the optional contact detail you type, the type of message, whether you used the web or app version, and basic device information that the form shows you before sending (such as browser, screen size and app version). This is used only to respond and to improve Breadbit.

Service providers

Breadbit uses Google Firebase (authentication and database) and a web host (server logs such as IP address and requested page may be kept by the host for security and reliability). These providers process data under their own terms.

What we do not do

• No advertising and no third-party advertising cookies.
• No analytics or tracking scripts in the application.
• No selling of personal data.

Cookies and storage

The app uses local storage and, when you sign in, the storage that Firebase Authentication needs to keep you signed in. It does not set advertising cookies.
