Privacy Policy

Who We Are

Lumenook Games publishes mobile games including Hexagon: Tower Defence and Sushi Tycoon (also referred to as Idle Sushi Tycoon). This policy explains how we handle data in those games and on our website.

Privacy contact: [email protected].

Data The App Handles

Hexagon: Tower Defence stores local gameplay data on your device, including settings, tutorial state, cards, rewards, scores, arena progress, daily progress, and other profile data needed to run the game.

The game may send compact backend records such as generated player identifiers, session tokens, session starts, battle starts and ends, run summaries, scores, enemies destroyed, selected upgrades, arena state, reward amounts, client errors, backend sync failures, rewarded-ad stages, and anti-abuse diagnostics.

If cloud save is enabled, Google Play Games Services on Android or iCloud on Apple platforms may process account and saved-game data according to those platform providers' terms.

Firebase Analytics may process allowlisted gameplay events and platform/runtime properties. Analytics is enabled by default and can be turned off in game settings.

Sushi Tycoon: The current version stores game progress in a local save file on your device. It has no account sign-in, cloud save, analytics, or online data transmission enabled, so Lumenook does not receive your Sushi Tycoon game progress.

Ads And Consent

Rewarded ads are optional. They are shown only after you choose an ad reward action in the app. The game should continue normally if an ad is unavailable, skipped, or fails to load.

When ads are available, Google AdMob may process advertising identifiers, ad interactions, approximate location, device information, diagnostics, and fraud-prevention signals. Where required, the app asks for consent or shows privacy options before requesting ads.

Ads are disabled in the current Sushi Tycoon version.

How We Use Data

We use data to run the game, save progress, verify rewarded-ad claims, prevent duplicate reward claims, provide leaderboard-style services where available, investigate bugs, measure onboarding and game balance, detect abuse, and improve stability.

We use compact diagnostics instead of raw frame logs or long event histories where possible.

Sushi Tycoon uses its local save only to preserve and restore game progress.

Sharing And Service Providers

We do not sell personal data. We may share or process data through service providers used to operate the app, including Google Play, Google Play Games Services, Firebase, AdMob, Apple iCloud, and website or backend hosting providers.

These providers may process data for app functionality, analytics, advertising, security, fraud prevention, diagnostics, cloud save, and platform services according to their own policies.

Sushi Tycoon does not send its local game progress to Lumenook or to third-party game services in the current version.

Security

For Hexagon: Tower Defence, network traffic to our backend uses HTTPS. Firestore is not intended to be directly writable by game clients. Backend reward and diagnostic endpoints use generated player/session credentials where applicable.

No method of storage or transmission is perfect, but we limit the data sent to what is needed for app operation, diagnostics, reward verification, and abuse prevention.

Data Retention

Local save data remains on your device until you reset it where the game provides that option, clear the app data, or uninstall the app. Cloud save data may remain with the relevant platform provider until removed through that platform's tools.

Backend player, run, diagnostic, server-event, and reward-intent records are retained only as long as needed for app operation, fraud prevention, diagnostics, security, or legal obligations. Some backend records may be automatically expired.

Your Choices

You can play core battles offline. You can choose whether to watch rewarded ads. In supported builds, privacy options are available from the app settings when required by the advertising consent system.

Sushi Tycoon progress is stored locally. Clear the app data or uninstall the app to remove that local save.

You can request deletion of identifiable backend app data through the data deletion page or by emailing [email protected].

Children And Audience

Our games are not directed to children under 13. If you believe a child has provided personal data, contact us so we can review and delete it where required.

International Processing

Service providers may process data in countries other than your own. We use these providers to operate the game, website, backend, ads, analytics, diagnostics, and platform services.

Changes

We may update this policy as games, SDKs, or legal requirements change. The latest version will remain available on this page.
