What does YuzuLingo send?
Cover and OCR stay on the device. If Share usage analytics is on, the extension sends product events through our API. Signed-in export and library features send account data needed for those features—not the video stream. Pressing the dictionary speaker for a Japanese word may also send that word and reading to JapanesePod101 or Jisho for a recorded clip.
Prerequisites
None.
Steps
On the device by default
- Burned-in cover and Interact recognition stay local.
- Dictionaries you install stay in this browser profile.
- On-device text-to-speech uses voices installed in your browser or OS.
When you press the speaker
- For Japanese, YuzuLingo may request a recorded clip from JapanesePod101 or Jisho using the headword and reading.
- If no clip plays, it falls back to on-device TTS. Other languages use TTS only.
Optional and account paths
- Turn off Share usage analytics in the popup Settings if you do not want product events.
- Export and library require a signed-in account and send only what those features need.
