We built FamFly.ai because we believe your family's sensitive data (Passports, KTNs, and Loyalty IDs) should never live in the cloud. Most travel tools store your info on their servers—we don't.
Technical Highlights:
Zero-Knowledge Architecture: Your data is encrypted locally using AES-256 encryption. We never have access to your master password or your vault data.
Local-First: All traveler profiles are stored in chrome.storage.local. No external database calls are made for your sensitive information.
Side-Panel Native: Built to leverage the browser's sidebar/side-panel for a seamless multitasking experience during the checkout process.
Lightweight: Pure, optimized JavaScript ensures zero impact on your browser speed or page load times.
Why we built this: As developers and parents, we wanted a tool that makes booking for a group fast without compromising on security. FamFly is our solution to the "manual data entry" fatigue of travel planning.
