No analytics SDKs. No tracking. Your typing, your saved logins and your cards stay on your device. Text leaves the phone only when you tap translate, and nothing else is sent anywhere. Getting started: enable CalBoard in Android Settings → System → Languages & input → On-screen keyboard, then pick it as your keyboard. Privacy policy: https://chandradcp.github.io/CBoard-releases/
