First and foremost: The LanguageTool Firefox add-on does not store the texts you write and does not track which websites you visit.

Please see https://languagetool.org/privacy/ for our full privacy policy.

When you use our Apps and Extensions, we collect the following information:

• Date and time of your usage
• Length of the text
• Language of the input text (but not the text itself)
• Duration of processing
• Number and type of errors detected, the page from which the request was sent (e.g. languagetool.org)
• App or extension version number
• Date of installation
• A randomly generated ID assigned to the input text
• In the event you uninstall, we also collect the number of times the add-on was used and the URL of the page where the add-on was last used.
• An anonymously generated internal ID for error rules whenever you accept or ignore correction suggestions. When you ignore a suggestion, we also store the text fragment underlined as incorrect and 15 characters to the right and left of it to track and avoid future errors in our system.
• In the rare circumstance that you experience an internal software error, we may store an anonymized record of the error for up to 14 days so that we can identify and fix the issue.
• To improve the speed of our software, we store checked records and the errors found in them for up to 15 minutes on our servers in the main memory (not on a permanent storage medium). The storage is done without IP address or other information that would allow the records to be assigned to a person.
• Only if you have an account on languagetool.org and if you are logged into the add-on with that account: Our extension contacts our servers periodically (about once a day) to let us know that you are an active user. The data collected for this purpose includes your browser type (e.g. Firefox) and the email address connected to the account you’re using. This allows us to track user activity and improve our software.

We do not store the Content you send for review when using our Apps and Extensions, except:

When you use our Editor on our website and the Editor integration in our apps for Windows, Mac, Android, and iOS, the following applies:

• When you use the Editor, we store the text Content you edit there to enable you to access your Content in the future. When you choose to delete a document, your deleted document will first be moved to the Recycle Bin. They are not permanently removed from our system until they are also deleted from the Recycle Bin.
• The storage takes place on servers in Germany at Amazon Web Services EMEA SARL, Niederlassung Deutschland, Marcel-Breuer-Str. 12, 80807 Munich, Germany.
