Version 1.3 — Effective: 11 October 2026
Cube Superfly for iOS and Android is developed and published by Spookwerk, a sole proprietorship (eenmanszaak) registered in the Netherlands (Chamber of Commerce / KvK number 42035025, registered office: De Nieuwe Erven 3, Unit 14531, 5431 NV Cuijk, Netherlands). The data controller under the GDPR is Spookwerk, reachable at privacy@spookwerk.app.
This policy explains how the app handles your data. The short version: everything Spookwerk's own code handles stays on your device; Spookwerk does not access, cannot access and will not access it. The optional leaderboards and, on Android, Google's SDK are described below.
Spookwerk does not collect, receive or store any personal data from Cube Superfly. The app contains no analytics, advertising, account system or crash reporting of Spookwerk's own, and Spookwerk runs no server for this app; the app sends nothing to Spookwerk, under any circumstance. The two platform services described below, Apple's Game Center on iOS and Google Play Games on Android, are Apple's and Google's.
The app stores your progress, settings, and local high scores — including the initials you type in for a high score — on your device, inside the app's own sandboxed container. This data is protected by your device's own encryption. It is deleted automatically when you delete the app. If Cube Superfly 1.02 was previously installed on this device, its save data is imported once, the first time version 2.0 launches.
On iOS, Cube Superfly offers an optional Game Center leaderboard. Game Center is Apple's service, governed by Apple's own privacy terms (see https://www.apple.com/legal/privacy/data/en/game-center/). If you are signed in to Game Center, your stored best score is submitted to the "High score" leaderboard under your Game Center profile when you sign in, and after that every score that enters your local top ten. To stop this, sign out of Game Center in iOS Settings; the game stays fully playable. Spookwerk never receives any Game Center data: scores go directly from your device to Apple.
On Android, Cube Superfly offers an optional Google Play Games leaderboard. Google Play Games is Google's service, governed by Google's privacy policy (https://policies.google.com/privacy). If you have a Play Games profile, the game signs you in automatically when it starts; if you do not, Google may offer to create one, once. While you are signed in, your stored best score is submitted to the "High score" leaderboard under your Play Games gamer profile, and after that every score that enters your local top ten. Spookwerk never receives this data: scores go directly from your device to Google.
The Android version contains Google's Play Games software development kit (SDK). Besides your gamer profile and your scores, the SDK sends app-usage analytics and diagnostics about itself to Google while it is part of the app, whether you are signed in or not. Google describes what it collects at https://developer.android.com/games/pgs/data-collection. The Data safety section of the Google Play listing declares these categories.
Lawful basis. Spookwerk does not see or store any of this data, but because the game includes Google's SDK, Spookwerk may be a joint controller with Google (GDPR Article 26) for sending it (Court of Justice of the EU, Fashion ID, C-40/17). The basis is legitimate interest (GDPR Article 6(1)(f)): the leaderboard is the game's one online feature, it carries only a score and your gamertag, nothing is used for profiling, and a player who is signed in to Play Games on a game installed from Google Play expects scores to reach Google. What signing out stops: signing out of Play Games stops score submissions and the use of your gamer profile, and the game stays fully playable. What it does not stop: the SDK's analytics and diagnostics, which reach Google while the SDK is in the app; uninstalling the game stops those.
Cube Superfly is made by Spookwerk, and Spookwerk holds nothing of yours to delete; the steps below run entirely through Apple's or Google's own account settings.
On Android:
On iOS:
Spookwerk has nothing of yours to delete. Google and Apple delete what they hold under their own retention terms, set out in Google's privacy policy and Apple's Game Center privacy page.
Your on-device saves, including local high scores and settings, disappear the moment you delete the app. Nothing is kept afterward.
Cube Superfly uses no third-party services besides Apple's Game Center on iOS and Google Play Games on Android, both described above. The game is built with the Unity engine; Unity's own engine services (analytics, advertising and crash reporting) are disabled in this app.
Cube Superfly is rated 4+ on the App Store. On Google Play its target audience is declared as 13 and over. Spookwerk collects no data from anyone, children included.
Because Spookwerk holds no personal data about you — everything lives only on your device, with Apple's Game Center or with Google Play Games — there is, in practice, no data at Spookwerk to exercise these rights against. For completeness, the GDPR rights are:
Spookwerk provides security updates for Cube Superfly on iOS until at least 20 September 2028, two years from its App Store release on 20 September 2026, and on Android until at least 11 October 2028, two years from its Google Play release on 11 October 2026. Updates are delivered through the App Store and Google Play at no additional cost. This is a minimum, not a maximum.
If you believe you have found a security vulnerability in Cube Superfly or in any Spookwerk service, please report it to security@spookwerk.app. We follow a coordinated vulnerability disclosure process: we confirm receipt, investigate, and keep you informed of the resolution. Machine-readable details are published in our security.txt.
