Sale or sharing of personal information

We do not sell personal information, and we do not share personal information for cross-context behavioral advertising. We do not use third-party advertising networks in Sudoku Coach. If this changes, we will update this page and provide the required choices.

Analytics choices

You can limit some app and website analytics through iOS privacy settings, browser cookie settings, and Google’s analytics opt-out tools. Analytics helps us improve lessons and diagnose product issues; it is not used to sell your personal information.
