Privacy Policy

Ossa: Dominoes | Grease Fire Studios LLC
Effective date: July 6, 2026

Ossa: Dominoes ("the game") is a single-player game for iOS made by Grease Fire Studios LLC, a Kansas limited liability company ("we", "us"). This policy explains what data is involved when you play, and who processes it. The short version: we don't run our own servers, we don't require accounts, and we never see your personal information. The only data processing happens through Apple and Google's advertising service, described below.

Data we collect ourselves

None. Your game progress (runs, scores, settings, unlocks) is stored locally on your device and is never transmitted to us. Deleting the app deletes this data.

Advertising (Google AdMob)

The free version of the game shows ads served by Google AdMob. To serve and measure ads, Google may collect and process:

• Device identifiers (such as the IDFA, only if you allow tracking when iOS asks)
• General device information (model, OS version, language, coarse location derived from IP)
• Ad interaction data (impressions, taps)

Where required (for example in the EEA/UK), you'll be asked for consent before any of this happens, and you can change your choice at any time via Settings → Ad Privacy inside the game. On iOS you can also deny tracking system-wide in Settings → Privacy & Security → Tracking. If you decline, you still get ads, just less personalized ones.

Google's own policies govern their processing: Google Privacy Policy · How Google uses data in AdMob apps.

Purchasing Remove Ads disables all advertising, after which no ad-related data is collected.

Purchases (Apple)

The Remove Ads purchase is processed entirely by Apple's App Store. We never receive your name, payment details, or billing information, only an anonymous receipt that unlocks the purchase on your device.

Game Center (Apple)

If you're signed in to Game Center, your run scores are submitted to Apple's leaderboards under your Game Center identity. This is governed by Apple's Privacy Policy. You can play without Game Center; leaderboards simply won't be available.

Children

The game is not directed at children under 13, and we do not knowingly collect personal information from anyone. Ad serving respects the age settings of your Apple account and the consent choices described above.

Changes

If this policy changes, the updated version will be posted at this address with a new effective date.
