Frequently Asked Questions

Extended answers to the things people most often ask about Sanli Technology and the Translate app.

Using the site

Do I need an account?: No. There is no sign-up flow, no login, no profile. Open /Translate/ and go.
Is it free?: Yes. The site is free to use.
Which browsers work?: Any modern browser: recent versions of Safari, Chrome, Firefox, and Edge on desktop and mobile. Very old browsers may have trouble with the clipboard-copy button; you can still select and copy manually.
Does it work on mobile?: Yes. The interface adapts to phone-size screens.

Translation quality and languages

How many languages are supported?: 249 target languages, plus auto-detect for the source. See Supported Languages for the full list.
Which translation engine is behind the tool?: Your text is forwarded to a large-language-model translation service called DeepSeek.
Is the translation always accurate?: No. Machine translation is best for gist, casual messages, and general context. It can fail on idioms, legal or medical wording, rare dialects, and cultural nuance. Always double-check important translations with a professional.
Why did I get an error?: The upstream service can rate-limit requests, temporarily go down, or reject input that triggers a safety filter. Try again in a moment, shorten the input, or rephrase.
Can I translate a whole document at once?: Not reliably. There are practical size limits. Paste a few paragraphs at a time.

Privacy and data handling

Does Sanli Technology store the text I translate?: No. Our server does not persist your text. It is forwarded to the upstream translation service and the response is returned to you.
Is my text sent to a third party?: Yes. Translations are produced by DeepSeek. If that matters to your use case, please review DeepSeek's own policies before submitting sensitive content.
Are there cookies?: Sanli Technology does not set first-party cookies for tracking.
Do you use Google Analytics or a similar tool?: Not currently.
