Privacy

Short version: there's no account, no tracking and no ads. Your words stay on your device.

What Mimitori keeps

Your saved words, the words you've marked as known, your review history and your settings. All of it lives in your browser's storage on the device you're using. It isn't sent to us, because there's no server for it to go to.

That also means if you clear your browser data or lose the device, the words go with it. Save a backup now and then: Settings → Save a backup gives you a file you can keep wherever you like.

What you open in it

Text you paste, PDFs, manga pages, videos and subtitle files are opened on your device. Reading a speech bubble and making subtitles both run on your device too. None of it is uploaded.

What it fetches from elsewhere

• Fonts come from Google Fonts, so your browser asks Google for them when a page loads. Google sees that request, like it would for any site using its fonts.
• The reading model (about 117 MB) downloads from Hugging Face the first time you read a manga page or PDF scan.
• The speech model (about 564 MB) downloads from Hugging Face the first time you make subtitles.

Both models are saved in your browser after that, so they only download once. They're files coming to you; nothing of yours goes the other way.

Anki

If you use the Mimitori add-on, the app talks to Anki on your own computer, at 127.0.0.1. That address never leaves the machine. A CSV export is just a file saved to your device.

No tracking

No analytics, no cookies, no ads and no third-party scripts watching what you do. This site doesn't track you either. The only thing it stores is whether you picked light or dark, and that stays in your browser.

Questions

The code is all on GitHub, so you can check any of this yourself. If something here looks off, open an issue.
