LanguageTool Grammar Checker 1.0.13

Privacy Policy

LanguageTool is a proofreading software. It works by sending the text to be checked to our servers over an encrypted connection. This policy describes what kind of data we store.

  • We don't store the text that you submit for style and grammar checking on languagetool.org, with the following exceptions:
    • If you explicitly submit feedback, for example about false alarms or undetected errors, we store that feedback.
    • In case of an internal software error, we log the sentence that caused the error so we can reproduce and fix the error.
  • To improve our proofreading service, we keep a log of the following information:
    • date and time, length of submitted text, text language, processing time on server, number of detected errors (but not the actual errors),
    • the page on which you submitted the request (referrer),
    • internal errors that occur (e.g. the browser add-on not being able to access the text to be checked),
    • the number of times you used the browser add-on (only transferred when you uninstall the add-on)
    This is an example of a log entry that LanguageTool generates on our server:
    2014-02-24 12:10:24 Check done: 793 chars, en-US, https://languagetool.org/, handlers:1, 3 matches, 132ms, sent
  • In our web server log files, your IP address is stored in an abbreviated form (like 192.168.xxx.xxx) so it cannot be used to identify you. Error messages like for exceeding the query limit are stored with the full IP so we can prevent abuse.
  • If you don't want any information to be transferred, download the stand-alone version from our homepage. It works locally without internet access and thus doesn't transfer any data.
