1. Information We Collect
1.1 Locally Stored Data
The App stores gameplay data locally on your device. This data is not personal and is used only to save your progress and preferences. It is never uploaded to any server controlled by us. This includes:
- Game progress (in-game currency, map unlocks, machine levels, slot expansions)
- Prestige, mission, and event state
- Gameplay statistics (estimated earnings per second, lifetime earnings)
- Save timestamps (used to calculate offline earnings)
- Language preference (detected from your device locale on first launch)
This data is saved in files such as save.json and settings.cfg within the app's private storage on your device.
1.2 No Account or Personal Data Collected by Us
We do not require you to create an account, and we do not collect personal information such as your name, email address, phone number, or location directly. The App does not send any of your locally stored data to our servers, because we do not operate any servers for this App.
1.3 Data Collected by Third-Party Services
Certain third-party services integrated into the App may collect information as described in Section 3 below. We do not control how these third parties collect or process their data; their practices are governed by their own privacy policies.
2. How We Use Information
We use the information accessible to us for the following purposes:
- Saving and restoring your game — locally storing progress so you can continue where you left off, including offline earnings calculations.
- Serving advertisements — via Google AdMob, to display rewarded and interstitial ads that support the free version of the App.
- Language detection — reading your device locale to select the App's display language on first launch.
- Improving stability — standard crash and performance information, if collected by the platform or third parties, is used to keep the App running smoothly.
3. Third-Party Services
The App integrates the following third-party services. Each service has its own privacy policy that governs how it collects and uses data. We encourage you to review them.
3.1 Google AdMob
We use Google AdMob (provided by Google LLC) to display ads, including rewarded video ads and interstitial ads. AdMob may collect and process certain device and usage data to serve and measure ads, including:
- Device identifiers (such as advertising ID)
- IP address (which may be used to derive coarse location)
- Device model, operating system version, and language
- Interaction data (e.g., ad impressions, clicks, views)
- Carrier and connection information
AdMob may use this data to provide personalized ads. You can opt out of personalized advertising at any time through your device settings (Settings → Google → Ads → Opt out of Ads Personalization) or by visiting Google's Ads Settings.
Relevant policies:
3.2 Google Play Services & Platform
The App runs on Android and may interact with Google Play Services, which may collect diagnostic and usage data as described in the Google Privacy Policy.
4. Data Storage & Security
All gameplay data is stored locally on your device in the App's private storage area. We do not transmit this data to any server under our control, and we do not maintain any server-side database of player information.
Data collected by third-party services (such as Google AdMob) is handled by those providers according to their own security and privacy practices. We have no access to, or control over, that data.
5. Data Retention & Deletion
- Local game data — retained on your device for as long as the App is installed. You can delete it at any time by using the in-game "New Game" option (which resets progress), by clearing the App's data from your device settings, or by uninstalling the App.
- Advertising data — governed by Google AdMob's retention practices. You can reset your advertising ID or opt out of personalized ads through your device settings at any time.
6. Children's Privacy
The App is intended for a general audience and is not directed specifically at children under the age of 13 (or the applicable age of digital consent in your jurisdiction). We do not knowingly collect personal information from children through the App.
If you believe that a child has provided us with personal information, please contact us at the email listed in Section 9, and we will take steps to delete such information. Parents may also use Google's Family Link tools to manage their child's app activity and advertising settings.
7. Your Rights
Depending on your location, you may have rights regarding your personal data, including the right to access, correct, or delete it. Because we do not maintain a server-side record of your data, the most effective way to exercise these rights is to:
- Delete local data: Uninstall the App or clear its data in your device settings (Settings → Apps → One-Tap Factory → Storage → Clear Data).
- Reset advertising ID: Settings → Google → Ads → Reset advertising ID.
- Opt out of personalized ads: Settings → Google → Ads → Opt out of Ads Personalization.
- Manage Google account data: Visit myaccount.google.com.
For any request regarding data held by third-party providers (such as Google AdMob), please contact the respective provider directly.
8. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will revise the "Last Updated" date at the top of this page. We encourage you to review this policy periodically. Continued use of the App after any changes indicates your acceptance of the updated policy.
