Take a screenshot in any app — chat, menu, news article, manga. Open Rosetta and the translation is already done. Translation chips appear over the original text, exactly where you were reading.

Open iOS Settings → Accessibility → Touch → Back Tap. Choose Double Tap or Triple Tap and scroll down to Shortcuts — pick the Rosetta shortcut. Then double-tapping the back of your iPhone captures a screenshot and opens it in Rosetta automatically.

30+ languages, including Chinese (Simplified & Traditional), English, Japanese, Korean, Spanish, French, German, Italian, Portuguese, Russian, Arabic, Hindi, Vietnamese, Thai, Indonesian, Turkish, Polish, Dutch, and Ukrainian.

No. Rosetta only looks at your screenshots. Other photos in your library are never read. You can revoke photo access at any time in iOS Settings → Privacy & Security → Photos → Rosetta.

By default, no. Rosetta uses Apple's on-device translation framework. Translations stay on your phone. The only exception is the optional Cloud mode — and only if you enable it and provide your own AI provider API key.

See the full privacy policy for details.

In Rosetta → Settings → Privacy, turn on Auto-delete screenshots after translating. After a translation completes, the source screenshot is moved to your Recently Deleted album.

1. Make sure you've granted Photos access (iOS Settings → Privacy & Security → Photos → Rosetta → Full Access).

2. Check that the screenshot actually contains text — Rosetta needs OCR-readable characters.

3. Try opening the screenshot manually from Library inside Rosetta.

If it still doesn't work, use Settings → Help & feedback → Report a bug — we read every report.

Open the translated screenshot, tap the Aa button at the top, and toggle Pinyin on. Pinyin only displays for Simplified and Traditional Chinese sources.

Yes. The default on-device translation works without internet. The first time you use a new language pair, iOS may prompt you to download the language model — that one download requires a connection.
