Duo Stack ("the App") is a block-stacking game developed by TeddyBronze, where gravity flips between the top and bottom of the board after every piece. This policy explains what information the App interacts with and how it is used.
Duo Stack does not require an account, does not collect your name, email address, or any personally identifiable information, and does not use analytics to track your behavior across other apps or websites.
The App saves your best score and sound/shake preferences locally on your device only. This information is never transmitted off your device and is deleted if you uninstall the App or clear its data.
Duo Stack displays ads served by Google AdMob. To serve and measure ads, Google and its partners may collect and process data such as your advertising ID, IP address, and general device information, and may use this data to show more relevant ads.
Duo Stack is not directed at children under 13. We do not knowingly collect personal information from children. [If this app will be listed as directed at children/families on Google Play, this section and the AdMob configuration must be updated to use Google's child-directed ad treatment — let me know and I'll help adjust it.]
Other than the advertising data described above, which is shared with Google AdMob to serve ads, we do not sell or share any information with third parties.
We may update this policy from time to time. Changes will be posted on this page with an updated revision date.
