History & Export

View local translation history, export as JSON, and clear data.

MinTranslate stores translation history locally in your browser (IndexedDB).

Older versions stored history in localStorage under mintranslate.translateHistory. New versions store history in IndexedDB and clear that legacy key automatically (no migration).

Where to view

Home shows a small “recent history” section
Full history page: /history

When items are saved

History is written after a translation succeeds.

Export as JSON
