Privacy Policy

Cube Online — effective 2026-09-29

This Privacy Policy applies to the Cube Online game (the "Application") for mobile devices and other platforms, created by itselb (the "Service Provider") and distributed as a free service. The Application is provided "AS IS".

What the Application collects

Game identifier. The Application generates a unique player identifier (UID) that identifies your profile, your saved progress and your reserved nickname. On Android the identifier may be derived from the device identifier (ANDROID_ID) so that your progress survives a reinstall. The raw device identifier never leaves your device: only a salted, irreversible hash of it is used. The UID is stored locally on your device and is sent to game servers when you play online.

Multiplayer data. When you join an online game, the following is transmitted to the game server you connect to:

Public dedicated servers may keep a chat log for moderation purposes. Such a log stores the time, the UID, the nickname and the message text, and is deleted automatically after a retention period configured by the server operator (180 days by default). Servers operated by third parties are outside the Service Provider's control and are subject to their own operators' practices.

Analytics (mobile versions). All mobile versions of the Application include Yandex AppMetrica, which collects standard technical and usage data: application version, session start and duration, device model, operating system version, language, country determined from the IP address, and crash reports.

Advertising (mobile versions). All mobile versions of the Application show advertisements via Yandex Mobile Ads. The advertising SDK may process your device advertising identifier and technical device data in order to select and measure ads.

Local data. Game settings, worlds and saved progress are stored on your device. Automatic Android cloud backup is disabled for the Application, so this data is not uploaded to Google servers.

What the Application does not collect

Permissions

The Application requests only the following Android permissions: INTERNET (multiplayer, analytics and advertising) and VIBRATE (haptic feedback). The advertising SDK may additionally read the advertising identifier provided by the system (com.google.android.gms.permission.AD_ID).

Purpose of processing

The data described above is used solely to run the game and its online features, to keep your progress and nickname associated with your profile, to moderate public servers, to diagnose crashes and to display advertising in the versions that contain ads (all mobile versions). It is not sold and is not used to build advertising profiles by the Service Provider.

Third-party access

Data may be processed by the following third parties, each under its own privacy policy:

The Service Provider may disclose data to third parties only where required by law (for example, in response to an official request from a competent authority).

Your choices

Data retention

Data associated with your UID (profile, progress, reserved nickname, server-side data) is retained for as long as you use the Application. If you do not join a server for longer than the period set by its operator (90 days by default), the Service Provider or the server operator reserves the right to delete your data on that server, in whole or in part, without prior notice and to release your nickname. Chat logs on public servers are deleted automatically after the retention period set by the server operator (180 days by default). Local data is removed when you uninstall the Application.

Children

The Service Provider does not knowingly collect personally identifiable information from children under the age of 13. Parents and legal guardians are encouraged to monitor their children's use of the Application, in particular the online chat. If you have reason to believe that a child has provided personally identifiable information through the Application, please contact itselbdev@yandex.ru so that the necessary actions can be taken.

Security

The Service Provider applies reasonable physical, electronic and procedural safeguards to protect the information it processes and maintains. Please note that chat messages you send in multiplayer are visible to other players on the same server.

Changes

This Privacy Policy may be updated from time to time. Changes are published by updating this page, and the effective date above is revised accordingly. Continued use of the Application after a change is deemed acceptance of that change.

Your consent

By using the Application you consent to the processing of your information as described in this Privacy Policy.
