Privacy Policy

Last updated:2026-03-20

Thanks for using ToneLang (“we”, “us”). We respect your privacy. This policy explains what we collect and how we use it. This policy applies to both the ToneLang website and the ToneLang iOS app.

Information we collect

  • Text you submit for translation and related parameters (source/target languages).
  • Basic usage data (e.g., error logs) to improve stability and user experience.
  • We do not intentionally collect sensitive personal information unless you include it in the text you submit.

How we use information

  • To provide translations in three tones (Formal/Casual/Literal).
  • To troubleshoot issues and improve performance.
  • To prevent abuse (e.g., excessive requests).

Third‑party processing

  • To provide translation, we may send your text to third‑party AI providers (e.g., DeepSeek).
  • How third parties store/use data depends on their policies. Please review their privacy policies.
  • We try to minimize what we send and only include what is needed to process the request.

Local storage

  • We may store your preferences (theme/language) and translation history in your browser (LocalStorage).
  • You can clear this data anytime in your browser settings.

Data retention

  • We try not to store your translation content long‑term on our servers. If temporary logs are needed for debugging, we remove or anonymize them within a reasonable timeframe.

Your choices

  • Do not submit sensitive personal data.
  • Clear your local data (history/preferences) anytime.
