PRIVACY POLICY FOR DEEP DRILL
Effective date: September 1, 2026
Stone Anvil Studio (“we”, “us”, or “our”) operates the mobile game Deep Drill. This Privacy Policy explains how information is handled when you use the game.
Information stored on your device
Deep Drill stores certain game data locally on your device, including:
• game settings and selected language;
• sound and music volume;
• records and gameplay progress;
• discovered objects and unlocked drills;
• purchase and entitlement status where applicable.
This locally stored information is used to operate the game and preserve your progress. We do not directly receive this information. It remains on your device until you clear the application data or uninstall the game.
Advertising and automatically collected data
Deep Drill uses Google AdMob to display rewarded advertisements. The Google Mobile Ads SDK may automatically collect and process:
• IP address, which may be used to estimate general location;
• advertising ID, app set ID and other device identifiers;
• interactions with the game and advertisements, such as app launches, taps and video views;
• diagnostic and performance information, including crash and application performance data.
This information may be used for advertising, analytics, security and fraud prevention. Data transmitted by the Google Mobile Ads SDK is encrypted in transit.
Where required by law, Deep Drill uses Google’s User Messaging Platform to request your consent before serving personalized advertising. You may refuse consent and receive non-personalized or limited advertising where available.

In-app purchases
Deep Drill may offer optional in-app purchases through Google Play. Payments are processed by Google Play. We do not receive or store your payment card or bank account information. Google may process purchase details according to its own privacy policy.
Sharing of information
We do not sell personal information. Information may be processed by Google and its advertising or service partners when required to provide advertisements, process purchases, prevent fraud, maintain security and comply with legal obligations.
Data retention and deletion
Game progress and settings stored locally remain on your device until you clear the application data or uninstall Deep Drill.
Information processed by Google is retained according to Google’s applicable policies. You may reset or delete your Android advertising ID through your device’s privacy settings.
Deep Drill does not currently create user accounts. Therefore, we do not maintain a separate account database containing player profiles.
Children’s privacy
Deep Drill is not specifically directed to children under the age of 13. We do not knowingly collect personal information directly from children. Parents or guardians who believe that a child has provided personal information may contact us.
Security
We take reasonable measures to protect information associated with the game. However, no electronic transmission or storage method can be guaranteed to be completely secure.
Changes to this Privacy Policy
We may update this Privacy Policy when the game, its services or legal requirements change. The updated version will be published on this page with a revised effective date.
