Easy Cube Games develops Lunisol, a single-player logic puzzle with suns and moons. This policy explains the information used by the game, why it is used, and how to contact us. Contact: easycubeindiegames@gmail.com.
On the first launch, the game shows a privacy notice with one Accept button. Pressing Accept accepts this policy and allows game analytics, crash reports and advertising, including personalized ads; the current version shows no ads yet (see Advertising). Acceptance is required to play. We save this decision on your device before any of these services start. There are no separate in-game switches for analytics, crash reports or advertising. You can read this policy from the first-launch notice and at any time from Settings → Privacy Policy; opening the policy does not change your decision.
Before acceptance, the game does not start the analytics, crash-reporting or advertising services and does not collect gameplay events to send them later.
No account, sign-in or cloud save is required. Your solved levels, best times, unfinished levels, the current endless level, hint counts, sound and language preferences, your privacy decision and the record of a "No ads" purchase are stored on your device. Resetting progress in Settings erases local game progress; it does not remove your privacy decision or your purchase. Android device backups, if enabled by your device or system settings, may handle application data separately from our game.
After acceptance, the game uses Google Firebase Analytics and Firebase Crashlytics:
These data help us understand how the game is played, balance the levels, measure advertising and purchases, and fix errors. Firebase Analytics may also record purchases made through Google Play automatically.
The current version of the game (1.0) shows no ads. The advertising SDK of the CAS.AI mediation platform is included in the app so that ads can be turned on in a later version, but the game does not start it, so no information is sent to CAS.AI or to advertising networks. Where a rewarded video will later give an extra hint, the game says that ads will be available later.
When ads are turned on in an update, the game will show a short ad break between levels (not before level 11 and not more often than the game's own interval) and offer an optional rewarded video when the free hints of a level are used up. Ads will be served through CAS.AI and the advertising networks it works with. These services may process the advertising identifier and other device identifiers, IP address, device and app information and ad interactions to deliver, limit, measure and personalize ads, subject to platform and audience restrictions. Each network's own privacy policy applies to its processing. You can reset or delete your advertising ID, or opt out of ad personalization, in your Android device settings. We will update this policy before such a version is released.
The game offers one optional one-time purchase, "No ads", through Google Play using Unity In-App Purchasing. It makes every hint free and keeps ads away once they are turned on. Google Play processes the payment; we do not receive your card or payment details. The purchase and a hash of its transaction number are stored on your device so that the purchase is not granted twice and can be restored. Google Play restores the purchase on the same Google account after reinstalling.
Google (Firebase, Google Play) processes information to provide its services; CAS.AI and its advertising partners will do so once ads are turned on. We do not sell your personal information. Service providers may process data on servers outside your country under their applicable terms and safeguards. Network communications use encrypted connections. No storage or transmission method can guarantee complete security.
Provider information: Firebase privacy information, Firebase Android data disclosure, Google Privacy Policy, CAS.AI Privacy Policy, Unity Privacy Policy.
Local data remain on your device until you reset progress, clear the app's data or uninstall the app, subject to Android storage and backup behavior. Firebase data follow their own retention rules: Analytics retention depends on the project's retention settings and the type of report, and Crashlytics describes a 90-day period before it begins removing applicable crash reports and installation identifiers. Once ads are turned on, advertising partners keep data under their own policies. This is not a promise that all game-related data are deleted within 90 days.
Uninstalling the app or clearing its data stops new collection from that installation but does not automatically erase information already processed by service providers. Contact easycubeindiegames@gmail.com with privacy questions or a request concerning your data, and name Lunisol in the message. Because there is no account and the services use installation identifiers, an email address alone may not identify an installation's records; we will explain what information is needed and what action is possible under the applicable law and the providers' tools. Please do not send passwords or payment information.
The game is not directed at children under 13 and does not ask for a date of birth. If you are a parent or guardian and believe a child has provided personal information, contact us at the address above.
We may update this policy when the game or its services change. The date above identifies the current version. New purposes of data use require a new in-game privacy decision. Questions: easycubeindiegames@gmail.com.
