Easy Cube Games develops Keepsake Nonogram, a single-player picture logic puzzle (nonogram) that works offline. 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 and crash reports. This version shows no ads. Acceptance is required to play. We save this decision on your device before these services start. There are no separate in-game switches for analytics or crash reports. 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 or crash-reporting services and does not collect gameplay events to send them later.
No account, sign-in or cloud save is required, and the puzzles play without an internet connection. Your solved pictures, unfinished puzzles, daily puzzle results and streak, the number of hints used today, settings (theme, number size, sound, vibration, language and similar preferences), your privacy decision and the record of a "Keepsake without ads" purchase are stored on your device. Resetting progress in Settings erases local game progress; it keeps your settings, your privacy decision and 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, tune the puzzles and hints, 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 the hint panel mentions a hint for watching an ad, it says that this will be available later. We will update this policy, and ask for a new in-game decision, before a version with ads is released.
The game offers one optional one-time purchase, "Keepsake without ads", through Google Play using Unity In-App Purchasing. In this version it removes the daily limit of three hints; once ads are introduced in an update, it will also keep them away. Google Play processes the payment; we do not receive your card or payment details. The fact of the purchase is stored on your device so that it is not granted twice. You can restore it on the same Google account from Settings → Restore purchases, for example after reinstalling.
When you choose to share a daily puzzle result, the game builds a short text (date, number of hints and undos, the week's marks and a link to the game) and hands it to the Android share sheet. The app you pick receives that text under its own policy; the game itself sends nothing.
Google (Firebase, Google Play) processes information to provide its services. 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, Unity Privacy Policy, CAS.AI 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. 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 Keepsake Nonogram 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.
