This Privacy Policy describes Our policies and procedures on the collection, use and disclosure of Your information when You use the Service and tells You about Your privacy rights and how the law protects You.
We use Your Personal data to provide and improve the Service. By using the Service, You agree to the collection and use of information in accordance with this Privacy Policy. This Privacy Policy has been created with the help of the Free Privacy Policy Generator.
Smash Blocks uses Google Analytics for Firebase to understand gameplay and campaign performance. When analytics collection is enabled, information includes screens visited, game modes, starts and outcomes, scores, tutorial progress, active play time, selected bots, and advertising interactions. Campaign attribution uses campaign labels rather than individual email recipient addresses or recipient IDs. The Firebase SDK may also process app-instance identifiers, device and app information, and automatically collected usage events. These data are not necessarily anonymous. We do not deliberately attach player names, email addresses or PlayFab account IDs to these analytics events.
Google AdMob provides advertising and processes data for ad delivery, measurement, fraud prevention and, where permitted, personalization. Linking AdMob with Firebase allows Analytics information to be used in AdMob and ad-revenue information to be available in Analytics. See Firebase privacy information, Google's Privacy Policy and how Google uses information from apps that use its services.
To measure our own advertising campaigns, for example on Google Ads, the Firebase SDK may use your device's advertising ID to attribute an installation or in-game actions to an advertisement you interacted with. This happens only where advertising storage is permitted under your privacy choices. Analytics information may be shared with our linked Google Ads account for campaign measurement and, where permitted, ad personalization. You can reset or delete your advertising ID in your device settings.
Google's User Messaging Platform manages regional privacy choices. Where the regional message applies, you can accept, decline or manage the purposes presented. You can review or withdraw these choices through Settings > Account > Privacy preferences > Manage privacy choices when the regional form is available. In the European Economic Area, the United Kingdom and Switzerland, gameplay analytics is collected only after you allow it in that message. In other regions, where this consent is not required, gameplay analytics is enabled by default; it stops if you opt out through a privacy choice the app presents in your region. Local testing builds do not send gameplay events to the production Analytics property.
Withdrawal stops future app analytics collection and resets the device's Firebase analytics data when collection was previously enabled. This does not itself delete data already held in reports or on Google's servers. For requests concerning your data, use the contact details in this policy.
Stellar Stacks uses Google Analytics for Firebase to understand how the game is played. When analytics collection is enabled, information includes rounds started and finished (round, result, score, moves and time), bosses defeated, sectors completed, tutorial progress, skills used, coins earned and spent, continues, energy running out, ads shown, screens opened, language changes, purchase attempts and Google Play Games sign-in results. The Firebase SDK may also process app-instance identifiers, device and app information, and automatically collected usage events. These data are not necessarily anonymous. We do not attach player names, email addresses or PlayFab account IDs to these analytics events. The game does not collect your advertising ID for analytics, and analytics data is not used for advertising or ad personalization.
Analytics collection is switched off when the game starts. Where Google's regional privacy message applies, it is turned on only after you allow analytics in that message; in other regions, where this consent is not required, it is enabled by default. You can review or withdraw your choice in the game under Settings > Ad privacy choices when the regional form is available. Withdrawal stops future collection and resets the device's Firebase analytics data; it does not itself delete data already held in reports or on Google's servers. Game progress, coins, skills and settings are stored on your device.
To show the online leaderboard, the game signs in to Microsoft Azure PlayFab with an identifier generated from your device, without asking for an email address or password. PlayFab assigns you a player ID and stores your total score, the nickname you choose (or a generated name such as "Swift Comet 27" if you do not choose one), your selected player icon and the list of icons you have unlocked. Your nickname, icon and total score are visible to other players on the leaderboard. Nicknames are checked against a list of offensive and reserved words before they are saved. If another player reports your nickname, we receive the report together with both player IDs so we can review it and, if necessary, reset the name. See the Microsoft Privacy Statement.
Google AdMob shows banner ads in the main menu, optional rewarded videos (for energy, skills, player icons or continuing a level) and occasional ads between levels, and processes data for ad delivery, measurement, fraud prevention and, where permitted, personalization. Google's User Messaging Platform manages regional privacy choices; where the regional message applies, you can review or change them in the game under Settings > Ad privacy choices. See Google's Privacy Policy and how Google uses information from apps that use its services.
In-app purchases are processed by Google Play. We receive confirmation of the purchased item but not your payment details.
