Prismara is a tower defense game. The game itself works offline. The free version shows ads served by Google AdMob; this page explains what that means for your data.
None. The developer has no server, no user accounts and no analytics of its own, and never receives your personal data.
The free version shows a banner on the main menu, interstitial ads between battles and optional rewarded video ads from Google AdMob. To show and measure ads, the Google Mobile Ads SDK may collect and process your device's advertising ID, IP address, approximate location derived from it, device and app information, and ad interaction data. Google processes this data under its own policies: How Google uses information from apps that use its services and Google Privacy Policy.
In the European Economic Area, the UK and Switzerland, the app asks for your consent through Google's consent form before personalised ads are shown. You can change your choice at any time in Settings → "Privacy options". You can also reset or delete your advertising ID in your Android settings. Prismara Pro users do not see ads and the ad SDK is not started for them.
Your settings (sound, vibration, language), stars, gems, Lab upgrades, records and daily challenge progress are stored only in the app's private storage on your device. They are deleted when you uninstall the app or clear its data. If Android backup is enabled on your device, this storage may be included in your personal Google backup under Google's own privacy terms.
Prismara Pro (one-time) and the optional gem packs are processed by Google Play Billing under Google's own terms. The app only asks Google Play which purchases belong to your Google account; the developer receives no payment card details. Gems can also be earned by playing.
Prismara is not directed at children under 13 and is not part of the Google Play Families programme.
If this policy changes, the new version will be published on this page with a new date.
