Your text and files
The Chinese text you type or paste, and the documents and photos you open, are processed in your browser. The conversion to pinyin, the word meanings, the pinyin keyboard, the reading of PDF and Word files and the text recognition in photos all run on your device. Your text, files and photos are not sent to our servers and we do not store them.
The "Translate to Chinese" button appears only in browsers that have a built-in translator, and the browser does the translating on your device.
The "Listen" button uses the voice built into your browser or operating system. Some browsers use online voices, in which case the browser itself may send the text to its own speech service. We do not control that and we never receive the text.
What is stored in your browser
The site keeps your settings and a random anonymous visitor ID in your browser's local storage. Nothing is sent from there except the visitor ID described below. You can delete all of it by clearing the site data in your browser. The site sets no cookies.
Analytics
We count how the site is used with Amplitude. Our server forwards the events to Amplitude, without your IP address. Each event has a name, a time, the anonymous visitor ID and a few settings of the page or the browser.
The events describe actions, not content. They include: the page was opened, text was entered (only its length and whether it contains Chinese), the example was used, a file was opened (only its type and length), the pinyin style or the text size was changed, a word was opened, the text was copied, downloaded or printed, audio was played, and the pinyin keyboard was used. They also carry the language of your browser, a mobile or desktop screen size, the site you came from, any UTM tags in the link, your country (from the network request) and whether the visit looks like a real person using the page.
The events never contain the Chinese text you entered, the contents of a file or a photo, or any name or email address.
What we do not do
There are no accounts, no ads, no advertising trackers, and we do not sell data.
