Privacy Policy

Effective date: October 8, 2026

The short version: our games have no accounts, never ask for your name or email, and your progress lives on your device.

This website

hypercubegames.com is a static site. It sets no cookies, runs no analytics, and collects nothing about you. If you email us, we keep that email so we can reply to it.

Robot GO! (mobile game)

The sections below cover the Robot GO! app specifically.

Information the app stores on your device

Your puzzle progress, settings, hints, hearts, and daily-challenge history are saved locally on your device. They are not uploaded to us. Deleting the app deletes them.

Advertising (Google AdMob, Meta Audience Network, Unity Ads)

The app shows ads, including optional "watch an ad" rewards. Ads are served through Google AdMob, which also lets Meta Audience Network and Unity Ads compete to fill each ad slot. These ad networks may collect device identifiers (such as the advertising ID), approximate location inferred from IP address, device information, and ad-interaction data to serve and measure ads. Google's advertising SDK provides the consent form described below.

In the European Economic Area and UK, a consent form is shown before any ad is requested, as required by law. You can decline personalized ads. The form is provided by Google's User Messaging Platform.
On iOS, the app asks for tracking permission through Apple's App Tracking Transparency prompt. If you decline, ads are still shown but are not personalized using cross-app identifiers.
California residents can turn on "Do Not Sell or Share My Personal Information" in the app's Settings, which makes every ad request non-personalized and tells Meta and Unity to limit their use of your data.

The partners' own privacy policies apply to their processing:

Meta Audience Network: facebook.com/privacy/policy
Unity Ads: unity.com/legal/game-player-and-app-user-privacy-policy

Advertising measurement (Adjust)

When we advertise the game, we use Adjust, a mobile measurement service, to tell which advertisement an install came from and whether our advertising is worth what it costs. Adjust receives the device advertising identifier, IP address (from which approximate location may be inferred), device and install information, and the value of ads shown to you or of a purchase you make. We use this only in aggregate, to judge advertising campaigns.

On iOS the advertising identifier is only used if you allow it at the App Tracking Transparency prompt. Declining does not stop you using the app. If you turn on "Do Not Sell or Share My Personal Information," the app also tells Adjust not to share your data with advertising partners. Adjust's privacy policy: adjust.com/terms/privacy-policy

From version 1.0.6 on iOS, the app also includes Meta's app-events SDK so that Meta can measure installs from our ads on Facebook and Instagram. It sends Meta app-launch and install events with device information and IP address, and the advertising identifier only if you allow tracking at the App Tracking Transparency prompt. "Do Not Sell or Share My Personal Information" turns on Meta's Limited Data Use for these events too. Meta's privacy policy: facebook.com/privacy/policy

Versions of the app released before October 2026 used Tenjin for the same purpose, with the same data. Tenjin's privacy policy: tenjin.com/privacy

Purchases (RevenueCat / Apple / Google)

The optional "Remove Ads" purchase is processed entirely by the Apple App Store or Google Play — the app never sees your payment details. RevenueCat, a purchase-management service, receives an anonymous app-generated identifier and your purchase state so the purchase can be restored on reinstall. RevenueCat's privacy policy: revenuecat.com/privacy

Analytics (Amplitude)

The app records anonymous gameplay events (for example "level 12 completed" or "hint used") under a random identifier so we can find confusing levels and fix bugs. These events are not linked to your identity, and we do not collect names, emails, contacts, or precise location. Amplitude's privacy policy: amplitude.com/privacy

Notifications

If you enable notifications, the app schedules local reminders (for example, your daily-challenge streak). These are generated on your device; no push server is involved.

Children

The app is a general-audience game and is not directed at children. Ads are requested with Google's "not child-directed" setting. We do not knowingly collect personal information from children.

Your choices

Personalized ads — decline via the consent form (EEA/UK), the iOS tracking prompt, or the "Do Not Sell" toggle in Settings.
Delete your data — the app's Settings include "Delete My Data," which wipes local progress and withdraws your advertising consent, so ads are served non-personalized from that point on. In the European Economic Area and UK it also resets the consent form, so you are asked again next time you open the app. The app generates a new anonymous analytics identifier for you at the same time. The device advertising identifier held by Google AdMob, Meta, Unity, Adjust (Tenjin in earlier versions), and RevenueCat can be reset in your device settings, or by contacting us.
Questions or requests — email support@hypercubegames.com and we will help, including with access or deletion requests under GDPR or CCPA.

Momodoku (mobile game)

The sections below cover the Momodoku app specifically.

Information Momodoku stores on your device

Your puzzle progress, streaks, race standing, settings, and power-up charges are saved locally on your device. They are not uploaded to us — Momodoku has no accounts and no servers of ours. Deleting the app deletes them.

Advertising in Momodoku (Google AdMob, Meta Audience Network, Unity Ads)

Momodoku shows ads, including optional "watch an ad" rewards, through Google AdMob. From version 1.3, Meta Audience Network and Unity Ads also compete through AdMob to fill each ad slot. These ad networks may collect device identifiers (such as the advertising ID), approximate location inferred from IP address, device information, and ad-interaction data to serve and measure ads.

In the European Economic Area and UK, Google's consent form is shown before any ad is requested. You can decline personalized ads, and (from version 1.3) change your choice later under Settings → Privacy Choices.
On iOS, the app asks for tracking permission through Apple's App Tracking Transparency prompt. If you decline, ads are still shown but are not personalized using cross-app identifiers.
California residents can (from version 1.3) turn on "Do Not Sell or Share My Personal Information" in the app's Settings, which makes every ad request non-personalized and tells Meta and Unity to limit their use of your data.

Partner policies: Google, Meta Audience Network, Unity Ads.

Momodoku advertising measurement and analytics (Adjust, Amplitude)

From version 1.3, Momodoku uses Adjust to tell which advertisement an install came from and whether our advertising is worth what it costs. Adjust receives the device advertising identifier (on iOS only if you allow tracking), IP address (from which approximate location may be inferred), device and install information, and the value of ads shown to you. If you turn on "Do Not Sell or Share," the app tells Adjust not to share your data with advertising partners. Adjust's privacy policy.

From version 1.3, the app also records anonymous gameplay events (for example "level 12 completed") under a random identifier with Amplitude, so we can find frustrating puzzles and fix bugs. These events are not linked to your identity, and Settings → Reset progress replaces that identifier with a new one. Amplitude's privacy policy.

Momodoku purchases and sharing

Momodoku currently offers no in-app purchases. The Share button composes a message on your device and hands it to your system share sheet — nothing is sent anywhere by us.
