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, iPad and Android.Ivy is our first game, and we're already thinking about what comes next.Get the CubeRoots board game here.

Ivy is just the beginning

Ivy is only the first game. There are plenty more waiting in the wings, and we'll be bringing them to life one at a time, staying true to what makes the originals special: simple rules, surprising depth and absolutely no nonsense.

CubeRoots Ivy privacy policy

Privacy Policy for CubeRoots Ivy
Effective date: 12 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 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) and Google Analytics for Firebase (for analytics), both provided by Google. 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)
CubeRoots Ivy displays ads provided by Google AdMob to support its free availability. With your permission, Google and its 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. 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 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 own privacy policy: Google Privacy Policy

2. 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 Firebase
3. 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.
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.
- 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.
- Non-personalised ads and fraud prevention: our legitimate interest in keeping the Game free, secure and working well.
- 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 and its 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, Google Analytics for Firebase, Apple Game Center and Google Play Games is handled by those third parties under their own privacy policies. We do not share your data with any other parties.
Data Storage
We do not operate our own servers and do not store personal data ourselves. Your game progress is saved on your device. Analytics data is kept by Google for 14 months. Any other data retained by Google or Apple is subject to their respective retention policies. Google 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.
As 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, and requests about leaderboard and achievement data through your Play Games profile or Apple Account. 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.
For any privacy concerns related to CubeRoots Ivy or CubeRoots Digital, please contact us at the address below.
Changes to This Policy
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.
