Effective date: August 27, 2026

The party responsible for the Undyra app is:

App name: Undyra
Package name: com.kulliongames.undyra
General Information
Protecting your privacy is important to us. Undyra is a locally playable brain-training and puzzle game. The app does not require a user account, display advertisements, or use analytics, tracking, or social networking services.
Data Stored Locally
Undyra only stores the following game and preference information locally on the user’s device:
– selected language
– personal high score for Wave Mode
– personal high score for Prism Flow
– local entitlement status for the Prism Flow expansion
– settings required for the operation of the app
This information remains within the app’s protected local storage area. It is not transmitted to the developer, used for advertising, or shared with other companies.
In-App Purchases and Google Play Billing
Undyra offers an optional one-time in-app purchase that permanently unlocks the Prism Flow expansion.
The purchase is processed exclusively through Google Play Billing. Google may process purchase-related information such as purchase status, product ID, transaction identifier, country, currency, payment method, and other information required to complete and manage the transaction.
The developer does not receive complete credit card, bank account, or other complete payment information. Undyra only queries Google Play to determine whether the Prism Flow expansion has been legitimately purchased, acknowledged, or restored.
The permanent product used by the app is:
Product ID: undyra_prism_flow

Advertising, Analytics, and Tracking
Undyra contains:
– no advertising
– no personalized advertising
– no analytics services
– no tracking services
– no social networking services
– no location access
– no user accounts
– no developer-operated servers
– no transmission of game progress to the developer
– no sale of personal information
Device Permissions
Undyra does not request unnecessary device permissions.
The app uses the official Google Play Billing interface exclusively to provide, verify, acknowledge, and restore the optional permanent in-app purchase.
Undyra does not request access to contacts, location, camera, microphone, photos, videos, files, calendar, call history, or SMS messages.
Music and Game Assets
All music, graphics, animations, and game assets used by Undyra are stored locally within the app. Playing menu music or gameplay music does not require the transmission of user information to the developer or to an external music service.
Data Sharing
The developer does not collect or share personal information through Undyra.
Purchase-related information is processed by Google Play as necessary to provide the optional in-app purchase. Google acts according to its own terms and privacy policies.
Data Retention and Deletion
Locally stored preferences and game progress remain on the device until:
– the app’s data is deleted through the Android system settings, or
– Undyra is uninstalled from the device.
Deleting the app data or uninstalling the app removes locally stored settings and high scores.
A permanent purchase made through Google Play may be detected and restored after reinstallation. Purchase and payment records are retained and processed by Google according to Google’s applicable legal, contractual, and operational requirements.
Because Undyra does not provide user accounts and does not store player information on developer-operated servers, there is no separate developer-held account or server-side game profile that requires a deletion request.
Data Security
Undyra limits data processing to what is technically necessary for the operation of the game and the optional in-app purchase.
Local game information remains within the protected app storage area provided by the Android operating system. Purchases are handled through the official Google Play Billing interface.
No method of electronic storage or transmission can be guaranteed to be completely secure. However, the app is designed to minimize data processing and does not maintain an external database of personal user information.
Children’s Privacy
Undyra is a general brain-training and puzzle game and is not specifically directed at children.
The app does not knowingly collect personal information from children. It does not provide user accounts, communication features, advertising, behavioral tracking, or social networking functions.
International Use
Undyra may be made available in multiple countries. The developer does not independently transfer personal user information between countries because the app does not collect or maintain such information on developer-operated servers.
Purchase processing through Google Play is subject to Google’s applicable terms, infrastructure, and privacy policies.
Changes to This Privacy Policy
This Privacy Policy may be updated if the app’s functionality, legal requirements, or third-party services used by Undyra change.
The current version of this Privacy Policy will always be published on this page. The effective date at the top of the page indicates when the policy was last updated.
