Cookie Notice

A short explanation of browser storage used by Billy's public website and web application.

Effective 2 September 2026Version 2026-09-02
On this pagePublic websiteWeb applicationYour controls

1. Public website

The promotional website at billyapp.org does not currently use advertising cookies, cross-site tracking, or optional analytics cookies. Our hosting and security infrastructure may still process essential request information such as IP address, browser type, timestamps, and security events to deliver and protect the site.

If we later add optional analytics or marketing technology, we will update this Notice and provide the consent controls required before using it.

2. Billy web application

The web application at app.billyapp.org uses browser storage that is necessary to keep you signed in, protect your session, remember security and onboarding state, and provide requested features. This storage is essential to the account service and is not used for third-party advertising.

Mobile biometric data is different. Face or fingerprint templates remain with your device operating system. Billy receives only the result of the device authentication check.

3. Your controls

You can delete website data through your browser settings. Removing essential Billy web-app storage will usually sign you out and may reset device-specific preferences. Blocking essential storage may prevent secure account features from working.

For questions, email support@billyapp.org. See the Privacy Policy for the broader processing notice.
