What usage events are sent?
When Share usage analytics is on, the extension sends product events through our API: install, video session start and end, zone create and remove, Interact toggled, dictionary lookup opened, Anki export success or failure, popup opened, and dictionary import. Video frames, OCR text, and mined vocabulary are never those events.
Prerequisites
Share usage analytics is on.
Steps
What is included
- Coarse context may include site host, optional video id, session duration, zone counts, language, and export success flags.
- Lookups are throttled so hover spam does not flood analytics.
Opt out anytime
- Turn off Share usage analytics in the popup Settings to stop new events.
