What happens when you use SentenceCoach.
Sentences you check
When you submit a sentence, it is sent to our language-model provider (DeepSeek) to generate the correction and returned to your browser. We do not require an account and we do not store your sentences with your name, email address or IP address. Short-lived rate-limit counters use your IP address only to prevent abuse. Do not paste personal or confidential information into the checker.
Analytics
We use Google Analytics and Cloudflare Web Analytics to see which pages are visited and how often the checker is used. Analytics events record the tool name, selected HSK level and whether a sentence had corrections, never the text you wrote.
