Your computer hasn't met us yet (it'll get over it)
Language Flipper isn't signed with a certificate yet, so macOS and Windows will ask you to confirm the first time you open it. Nothing is wrong — here is exactly what you'll see.
On macOS
- Open the DMG and drag Language Flipper into your Applications folder.
- On first launch, macOS says it can't verify the developer.
- Open System Settings → Privacy & Security.
- Scroll down and click “Open Anyway” next to Language Flipper.
On macOS 14 and earlier you can instead right-click the app and choose Open.
Language Flipper then walks you through granting Accessibility and Input Monitoring permission — that's how it reads and replaces your text.
On Windows
- Run Language-Flipper-Setup.exe.
- SmartScreen shows a blue “Windows protected your PC” screen.
- Click “More info”.
- Click “Run anyway”.
Windows shows this for any new publisher it hasn't seen many times yet. A signing certificate is on the way.
