Privacy Policy
Mahjong Helper does not store any information online unless you choose to share a ‘match’, in which case the selected match’s data is saved in a database online for sharing with other players also using the app, and only to those who you choose to share with.
Player names as entered in the app will be stored, but no other identifiable information is saved. You can disable sharing of the match at any time, which will remove it from the database.
