Frequently Asked Questions

Is Hueglass free?

Yes. Hueglass is free to play, with ads served by Google AdMob: a banner on the menu and below the play field, and a full-screen ad after some completed levels. You can earn ad-free play each month by watching short videos, or go ad-free every month with an optional monthly subscription.

How do I play?

Pour dyes (Rose, Amber, Aqua, Milk, Ink and others) into the beaker. Mixing is subtractive, like real transparent dyes: more dye darkens and saturates, Milk lightens, Ink deepens. Watch the colour readout and match the target orb within the tolerance; the Lab Notebook records the colours you discover and the Recipes shelf keeps your best mixes. Pouring is free and you can drain and retry; fewer pours and a closer match earn more stars. There are no timers and no lives.

How do I earn ad-free play each month?

Open Ad-free from the menu and watch short rewarded videos. A progress bar shows how many videos you have watched this month and the date it resets. Reaching the goal turns ads off until that date. Watching is always your choice.

What does the monthly subscription cost, and how does it renew?

Ad-free Monthly is US$2.99 per month (local price shown in the store). It renews automatically every month until you cancel, and it removes ads for as long as it is active.

How do I cancel the subscription?

iPhone and iPad: Settings > your name > Subscriptions > Hueglass > Cancel Subscription. Android: Google Play > Profile > Payments & subscriptions > Subscriptions > Hueglass > Cancel subscription. Deleting the app does not cancel it.

How do I restore my subscription?

Open Ad-free in the app and tap Restore purchases. You need to be signed in to the same Apple ID (iPhone and iPad) or Google account (Android) that subscribed.

Does the game work without internet?

Yes. The game plays fully offline; only ads and subscription checks need a connection.

Is my data private?

The app has no accounts and no servers of ours, and your progress stays on your device. It shows ads served by Google AdMob, which may use your advertising ID. Where the law requires it the app shows Google’s consent form, and on iPhone and iPad it asks permission through Apple’s App Tracking Transparency prompt. See the Privacy Policy.

Which terms apply?

Apple’s standard Licensed Application End User License Agreement on iPhone and iPad, and the Google Play Terms of Service on Android.

My progress is missing. What should I do?

Progress is stored on your device, so it does not carry over to a new device or after an uninstall.
