Who we are
10Ten is developed and published by The Cat and Chicken Company, based in the Netherlands. You can reach us at info@catandchicken.nl.
Data we collect
We do not collect any personal data ourselves. 10Ten does not require an account and does not ask for your name, email address, or location. Your game progress is stored locally on your device only.
Local storage
Your game records (best times, ranks, badges) are saved locally on your device only using the browser's localStorage. This data never leaves your device and is not shared with us or any third party. You can delete this data at any time by clearing the app's data in your device settings.
The free version of 10Ten displays advertisements provided by Google AdMob. AdMob may collect and use data including your device's advertising identifier (GAID), IP address, and app usage data to serve personalised or non-personalised ads. You can remove all ads with a one-time in-app purchase.
In accordance with GDPR, users in the EEA, UK and Switzerland will be asked for consent before personalised ads are shown. You can withdraw or manage your consent at any time via Contact → Privacy Settings in the app.
For more information, see Google's Privacy Policy at policies.google.com/privacy.
In-app purchases
10Ten offers a one-time "Remove Ads" purchase processed by Google Play Billing. We do not receive or store your payment details. All payment processing is handled securely by Google.
