Strictly Necessary Storage
The app uses browser local storage for cart, design, saved checkout, and pending-order state so the customer can continue the order flow.
Authentication
Firebase Authentication may use cookies, IndexedDB, or local browser storage to keep signed-in users authenticated.
Preferences
Design and cart preferences may be stored locally in the browser.
Analytics and Marketing
The current application does not intentionally load marketing trackers. If nonessential analytics or advertising cookies are added later, an appropriate consent control should be implemented before loading them.
