Privacy & Storage

Understand what MinTranslate sends, what it stores locally, and how to clear it.

Data flow (translation)

MinTranslate sends translation requests from your browser to the Provider you configured.

What is typically included:

  • The text you entered
  • The system prompt you set
  • The translation direction (Chinese ↔ English)

Note: MinTranslate does not proxy your translation content or store translation text on a server.

What is stored locally

MinTranslate uses browser storage for local data:

  • localStorage: configuration (providers, system prompt, UI preferences)
  • IndexedDB: translation history

This data is local to your current browser/device and is not automatically synced across devices.

Common keys:

  • mintranslate.aiProviders: all provider configs (including API keys)
  • mintranslate.aiDefaultProviderId: the default provider id
  • mintranslate.appSettings: app settings such as system prompt
  • mintranslate.uiLanguage: UI language preference

IndexedDB:

  • Database: mintranslate
  • Store: translate-history (translation history)

How to clear

Options:

  • Delete providers in /settings (local only)
  • Clear translation history in /history
  • Use your browser’s “Clear site data” to remove everything

Security tips

  • Avoid configuring cloud provider API keys on shared/public computers.
  • For sensitive content, consider using a separate browser profile.
  • For local-only workflows, consider using Ollama (local models).

History & Export

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