Privacy Policy

NumberPlace ("the Service") respects your privacy and is committed to protecting your personal information.

Information We Collect

The Service stores game progress, statistics, your daily challenge record and mini Sudoku sticker record in your browser's local storage (on your device). This data is not transmitted to our servers. You can delete it at any time with the erase buttons on the statistics page and the mini Sudoku page.

Push Notification Subscriptions

If you subscribe to Daily Challenge notifications, we store the subscription data needed to deliver them (the push service endpoint URL, encryption keys, your display language, and your time zone offset) on our server. This data is used only to send notifications and contains no personally identifying information.

You can unsubscribe at any time with the button on the app guide page. Cancelled or expired subscriptions are deleted.

Analytics

We use a third-party analytics tool to analyze site usage. This tool uses cookies to collect data, but does not include personally identifiable information.

If you enable Do Not Track or an equivalent setting in your browser, the Service does not load the analytics tool.

Advertising

The Service may use third-party advertising services. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.

Google's use of advertising cookies (such as the DoubleClick cookie) enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google's Ads Settings (adssettings.google.com). Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info.

Cookies

The Service uses localStorage for theme preferences. Third-party cookies may be used by the analytics tool and the advertising services described above. You can disable cookies in your browser settings, although some features may no longer work as intended.
