Each scenario includes vocabulary warm-up and guided dialogue so phrases stick when you need them. 8 languages to learn English, Chinese, Japanese, Korean, Spanish, French, German, and Russian—with a multilingual app interface. AI-generated custom scenarios Describe a situation you want to practice (e.g. “renting a bike in Tokyo”), and Privoca builds a tailored lesson on your device. Why Privoca? • On-device AI: core tutoring and ASR run locally—your data stays on your phone • Scenario-based learning: speak in context, not isolated word lists • Great for commutes, travel prep, and last-minute speaking practice First-time setup To keep the install size small, Gemma and WhisperKit models are downloaded inside the app on first launch (~3GB). Resume supported; users in China can use the ModelScope mirror. After download, practice works offline. Privacy & data Privoca does not operate backend servers to store your conversations. Your voice, text, and practice data stay on your device by default. The microphone is used only when you actively record. Model files are downloaded from third-party sources (e.g. Hugging Face, ModelScope) to your device for offline use. Full Privacy Policy: https://privoca.app/privacy Open Privoca.
