Planet Defence (package com.giuseppetumino.solarsystem) is a free Android game made by
Giuseppe Tumino. It shows ads and offers one optional in-app purchase that removes them. This page
explains what data the app handles, who receives it and what you can do about it.

The app keeps a few settings on your phone: whether audio is on, whether you have seen the tutorial, whether you bought "Remove ads", when an ad-free period from a rewarded video ends, and a best score still waiting to be sent to the leaderboard. These settings can be included in your phone's Android backup to your Google account. They are deleted when you uninstall the app or clear its data.
The app shows banner, full-screen and rewarded video ads through Google AdMob. To serve and measure ads and to prevent fraud, the Google Mobile Ads SDK collects and shares with Google:
Personalised ads are shown only if you give your consent where it is required. Without it, Google may still show non-personalised ads, which are chosen from the context and your general location. You can reset or delete your advertising ID in your phone's settings (Settings > Privacy > Ads, or Settings > Google > Ads, depending on the phone).
How Google uses this data: How Google uses information from sites or apps that use its services and Advertising at Google.
If you buy "Remove ads", the app does not start the ads SDK at all and shows no consent form. During an ad-free period earned with a rewarded video, the app shows no banners and no full-screen ads, but it still loads the rewarded video, so you can watch another one to extend the period.
The consent form is shown by Google's User Messaging Platform. It stores your choice on your device and passes it to AdMob. "Privacy options" in the menu opens the form again, so you can withdraw or change your consent.
The app signs you in to Google Play Games automatically, if you have a Play Games profile. Signing in is optional: the game works without it, but then the leaderboard and achievements are not available. When you are signed in, Google receives your Play Games player ID, your gamer name and avatar, your scores and the achievements you unlock. Your best score appears on the public "High scores" leaderboard, which other players can see according to the visibility settings of your Play Games profile. Google also collects analytics and diagnostic data to keep the service working. You can manage or delete your Play Games profile in the Google Play Games settings.
The "Remove ads" purchase is handled by Google Play. I do not receive your payment details. The app only receives the state of the purchase from Google Play and stores it on your device.
Google Analytics for Firebase collects anonymous statistics about how the app is used: for example app opens, screens, session length, the app version, the device model, the Android version, the language and the country estimated from the IP address. It uses an identifier created for this installation of the app. I use these statistics to understand how the game is played and to improve it. They do not contain your name or email address.
When the app crashes or hits an error, Firebase Crashlytics sends a report with the technical details of the error, the state of the app at that moment, the device model, the Android version and an identifier of this installation. Crashlytics keeps reports for 90 days. I use them only to find and fix bugs.
Firebase privacy information: Privacy and Security in Firebase.
The data described above goes to Google LLC and Google Ireland Limited, which provide AdMob, Play Games Services, Play Billing and Firebase. Google may process it in countries outside your own, including the United States, under the safeguards described in Google's Privacy Policy. I do not sell your data and I do not share it with anyone else.
All the data these services send leaves your device encrypted (HTTPS/TLS).
The app is not directed at children under 13. I do not knowingly collect data from them. If you are a parent or guardian and think your child has provided personal data, contact me and I will help you have it deleted.
If the app starts to handle data in a different way, I will update this page and its effective date.
