Lancar is an offline Indonesian vocabulary trainer. It is built to work entirely on your device.
Nothing. Lancar does not collect, transmit, or share any personal data. There are no accounts, no analytics, no advertising, and no third-party SDKs.
Your learning progress, settings, and the optional display name you may enter during onboarding are stored only on your device. They are never uploaded anywhere. Uninstalling the app removes them.
Lancar makes no network connections at runtime. All content and audio are bundled inside the app.
If you use the pronunciation-practice feature, Lancar uses your microphone and on-device speech recognition only to check what you say, on your device. Audio is not recorded, stored, or transmitted.
Lancar contains no objectionable content and collects no data, so it is safe for all ages.
