Yes! The app is completely open source (all code is visible on GitHub). It doesn't collect any data, doesn't store your password, and only saves your login session cookie - exactly like using Messenger in a web browser.
No! After your first login, the app remembers your session. You'll stay logged in until you manually log out.
Not currently. You'll need to log out and log back in to switch accounts. Multi-account support may come in a future update!
The app is not "code signed" (a digital signature that costs $300+/year). This is normal for free open-source software. Click "More info" → "Run anyway" to install.
Absolutely! This app is just a window to messenger.com - your messages go directly to Facebook's servers, exactly like using Messenger in Chrome or Edge. The app doesn't read, store, or send your messages anywhere else.
This app is designed for personal Facebook Messenger accounts only.
Not yet - currently Windows only. Mac and Linux support is planned for future releases!
