Privacy Checklist for Japanese Learning Chrome Extensions (2026)
What permissions Japanese anime learning extensions need — Listening Mode, subtitles, local storage — and red flags before you install.
Learning extensions ask for broad site access because Netflix/Crunchyroll players are hostile environments. That does not mean every permission is fine — read the privacy story.
Healthy signs
- Local-first card storage explained clearly
- Listening Mode / transcription documented (how CR works)
- Open source or a real privacy page (ours)
Red flags
- Vague "we may share data with partners"
- Permissions far beyond video sites you use
- No explanation of audio capture
