Divvun's keyboard apps do not harvest text written with them. All processing is done on the telephone.
Divvun's grammar checkers do not collect any text. We do log that the grammar checker is being used, and the IP address of the user, but we do not log the text being sent to our servers. When using our grammar checker with GSuite and o365 the text must be sent to our servers for processing.
None of the other Divvun tools collect any text or user data.
