Our Story
CubeRoots started at a kitchen table in 2020.Our co-founder Eddy designed a physical game built around a set of numbered, coloured wooden cubes. He began experimenting with different ways those cubes could interact and created a collection of original games around them.One of those games was Ivy.A few years later, Simon thought Ivy would make a great mobile game. There was one problem: he'd never built one before.So he taught himself.After a year of coding, testing, redesigning and a lot of trial and error, the physical game became CubeRoots Ivy for iPhone and iPad, with Android coming on 3 December 2026.Ivy is our first game, and we're already thinking about what comes next.Get the CubeRoots board game here.

CubeRoots Ivy privacy policy
Privacy Policy for CubeRoots Ivy
Effective date: 26 October 2026
Developer: CubeRoots Digital Ltd.Introduction
This Privacy Policy explains how CubeRoots Ivy ("the Game") handles information when you play it on iOS or Android. We have designed the Game to be as privacy-friendly as possible. We do not collect personal information directly, such as your name or email address. The Game only shows personalised ads if you give permission, only sends notifications if you turn them on and, in the UK, the European Economic Area (EEA) and Switzerland, only uses analytics if you give permission. You can change your choices at any time.
CubeRoots Digital Ltd. is the data controller for the Game.Third-Party Services
The Game integrates Google AdMob (for advertising), with some ads served by Unity Ads through AdMob mediation, and the following Firebase services provided by Google: Google Analytics for Firebase (for analytics), Firebase Cloud Messaging (for optional notifications), Firebase Remote Config (for update checks) and Cloud Firestore (for referral codes). It also works with Apple Game Center on iOS and Google Play Games on Android for leaderboards and achievements. Each is described below.1. Advertising (Google AdMob and Unity Ads)
CubeRoots Ivy displays ads provided by Google AdMob to support its free availability. AdMob uses mediation, which means some ad requests may be filled by Unity Ads, an advertising network provided by Unity Technologies. With your permission, Google, Unity and their advertising partners may use your device's advertising identifier (the IDFA on iOS, or the Google advertising ID on Android) and information about how you use the Game to show you more relevant ads and to measure how well ads perform. We ask for this permission in the following ways:
- In the UK, the EEA and Switzerland, the Game shows a consent form provided by Google the first time you reach the main menu. You can accept, refuse, or choose which purposes you agree to. Your choices are passed on to Unity Ads. The same form covers analytics (see section 2).
- On iOS, the Game shows a short explanation followed by Apple's App Tracking Transparency (ATT) prompt. If you choose "Ask App Not to Track", your advertising identifier is not shared or used for tracking.
- On Android, there is no system tracking prompt. Your choices in the consent form, and your device's ad settings, control whether ads are personalised.
- If you say no, you will still see ads, but they will be non-personalised. Refusing never blocks any part of the Game.
Non-personalised ads are based on general context, such as the app you are using and your approximate location, rather than your activity in other apps and websites.
Whether or not ads are personalised, Google and Unity may collect technical data in connection with ad delivery, such as device type, operating system, IP address, approximate (coarse) location, ad interaction data (impressions and clicks), and crash and performance data, for fraud prevention, ad serving and measurement. On Android, this may include the app set ID, an identifier used for analytics and fraud prevention. Where you have given permission, this also includes your device's advertising identifier.
AdMob is linked to Google Analytics for Firebase, so information about ads shown in the Game (such as ad type and estimated revenue) is combined with our analytics, and Google may use analytics data to improve ad delivery through AdMob.
You can change your choice at any time:
- UK, EEA and Switzerland: open the Game's menu and tap Privacy Settings to reopen the consent form.
- US states with privacy laws (such as California): open the Game's menu and tap Privacy Settings to opt out of the sale or sharing of your personal information for targeted advertising.
- iOS tracking: go to Settings > Privacy & Security > Tracking and turn tracking off for CubeRoots Ivy.
- Android advertising ID: go to your device's Settings > Privacy > Ads (or Settings > Google > Ads on some devices) to reset or delete your advertising ID.
This is governed by Google's and Unity's own privacy policies: Google Privacy Policy and Unity Privacy Policy
For more on how Google uses data from apps that use its services, visit: How Google uses information from apps2. Analytics (Google Analytics for Firebase)
CubeRoots Ivy uses Google Analytics for Firebase, a service provided by Google, to understand how players progress through the Game so we can improve it, for example to find levels that are too difficult. It collects:
- A randomly generated app-instance identifier, created when you install the Game. It is not linked to your name, email address or any account.
- In-game activity, such as levels started and completed, the highest level you have reached, when you last played, and which screens you visit.
- Device and app information, such as device type, operating system and version, app version and language.
- Approximate location (country, region or city), worked out from a masked version of your IP address. The Game does not use your device's location services.
- Information about ads shown in the Game, such as the type of ad and its estimated revenue.
- On Android, the Google advertising ID. On iOS, the advertising identifier (IDFA) is only accessed if you allow tracking through Apple's ATT prompt.
We do not set a user ID, and we do not use this data to identify you or to build advertising profiles of you. We use ad revenue data only to understand which ads support the Game, not to identify or target you.
In the UK, the EEA and Switzerland, analytics only stores an identifier on your device if you agree in the consent form. If you refuse, Google Analytics only receives limited information that is not linked to an identifier on your device. You can change your choice at any time through Privacy Settings in the Game's menu.
Analytics data is kept for 14 months and then deleted automatically.
For more information on how Google handles this data, visit: Google Privacy Policy and Privacy and Security in Firebase3. Leaderboards and Achievements (Game Center and Google Play Games)
If you are signed in to Apple Game Center (iOS) or Google Play Games (Android), the Game submits your score and achievement progress to that service so they can appear on leaderboards and in your achievements list. Your gamer name, avatar and profile visibility are controlled in your Game Center or Play Games settings, not by us. You can play the Game without signing in to either service.
This data is handled by Apple or Google under their own privacy policies: Apple Privacy Policy and Google Privacy Policy
You can delete your Google Play Games data for the Game from your Play Games profile. Game Center data is managed through your Apple Account settings.4. Notifications (Firebase Cloud Messaging)
The Game can send occasional notifications, for example to let you know when new levels are available. Notifications are optional and are only sent if you turn them on when the Game asks, or later in the Game's menu.
If you turn notifications on, Firebase Cloud Messaging, a service provided by Google, creates a push token for your device. This is a randomly generated identifier used only to deliver notifications to the Game on your device. Your device is subscribed to a notification group based on the language you have chosen in the Game, so that notifications arrive in that language. The push token is not linked to your name, email address or any account, and is not used for advertising or tracking.
You can turn notifications off at any time in the Game's menu or in your device's settings (on iOS, Settings > Notifications > CubeRoots Ivy; on Android, Settings > Apps > CubeRoots Ivy > Notifications).5. Update Checks (Firebase Remote Config)
When you open the Game, it checks Firebase Remote Config, a service provided by Google, to find out whether a newer version of the Game is available so it can let you know about updates and new levels. To do this, Firebase uses a randomly generated installation identifier and basic app and device information, such as app version, operating system and language. This is not used to identify you.6. Referral Codes (Cloud Firestore)
If you share your referral code with a friend, or redeem a friend's code, the Game stores the code, a randomly generated identifier for your installation of the Game, and a record of when codes are redeemed in Cloud Firestore, a database service provided by Google. This is used to award referral bonuses and to stop codes being redeemed more than once. It is not linked to your name, email address or any account. If you never share or redeem a code, nothing is stored.How We Use This Information
The data collected by our third-party services is used solely to:
- Display advertisements, including personalised ads where you have given permission, and keep the Game free to play.
- Measure ad performance and earnings.
- Show leaderboards and achievements if you are signed in to Game Center or Google Play Games.
- Understand how players progress through CubeRoots Ivy, such as which levels players find difficult, so we can fix bugs and improve gameplay.
- Send notifications, such as new level announcements, if you have turned them on.
- Let you know when an update to the Game is available.
- Award referral bonuses and prevent misuse of referral codes.
- Monitor app stability and performance.
We do not use this data for any other purpose.Legal Basis (UK and EEA)
- Personalised ads and tracking: your consent, which you can withdraw at any time through Privacy Settings in the Game's menu.
- Analytics: your consent, which you can withdraw at any time through Privacy Settings in the Game's menu.
- Notifications: your consent, which you can withdraw at any time in the Game's menu or your device's settings.
- Non-personalised ads and fraud prevention: our legitimate interest in keeping the Game free, secure and working well.
- Update checks: our legitimate interest in making sure players know when new levels and fixes are available.
- Referral codes: our legitimate interest in providing the referral feature to players who choose to use it and preventing its misuse.
- Leaderboards and achievements: our legitimate interest in providing these features to players who choose to sign in to Game Center or Google Play Games.Data Sharing
We do not sell your personal data for money. Where you have given permission, Google, Unity and their advertising partners receive information to personalise ads, which some US state laws may treat as a "sale" or "sharing" of personal information. You can opt out at any time through Privacy Settings in the Game's menu. Data processed by Google AdMob, Unity Ads, Google Analytics for Firebase, Firebase Cloud Messaging, Firebase Remote Config, Cloud Firestore, Apple Game Center and Google Play Games is handled by those third parties under their own privacy policies or on our behalf. We do not share your data with any other parties.Data Storage
We do not operate our own servers. Your game progress is saved on your device. Referral code records are stored on our behalf in Cloud Firestore and are kept for as long as the referral feature is available, or until you ask us to delete them. Push tokens are kept until you turn notifications off or uninstall the Game, and tokens that are no longer used expire automatically. Analytics data is kept by Google for 14 months. Any other data retained by Google, Unity or Apple is subject to their respective retention policies. Google, Unity and Apple may process data outside the UK and EEA, including in the United States, using safeguards such as Standard Contractual Clauses.Children's Privacy
CubeRoots Ivy is not directed at children under the age of 13 (or under 16 in the European Economic Area). We do not knowingly collect personal information from children. If you believe a child has provided personal data through the Game, please contact us and we will take steps to address it.Your Rights
Depending on your location, you may have rights regarding your personal data, including the right to access, correct, or request deletion of data held about you, to object to how it is used, and to withdraw your consent at any time.
Apart from referral code records, we do not hold personal data ourselves. Requests about ad and analytics data are handled through Privacy Settings in the Game's menu and your device's ad settings, notifications can be turned off in the Game's menu or your device's settings, and requests about leaderboard and achievement data are handled through your Play Games profile or Apple Account. To request deletion of referral code records, email us with your referral code. For data processed by our third-party services, please refer to their privacy policies or contact them directly. If you are unsure, email us and we will help.
If you are in the UK, you can also complain to the Information Commissioner's Office (ico.org.uk). In the EEA, you can contact your local data protection authority.

We may update this Privacy Policy from time to time. Any changes will be posted within the Game, on the App Store and Google Play listings, or on our website. Continued use of the Game after changes are posted constitutes your acceptance of the updated policy.Contact Us
