Privacy Policy for Submarine Runner

Effective date: October 31, 2026
Developer: The Craft Nest
App: Submarine Runner
Package name: com.tcnthecraftnest.submarinegame

This Privacy Policy explains what information The Craft Nest ("we", "our", "us") collects when you install and play Submarine Runner, how we use it, and the choices you have.

1. Information we collect

Account information (optional): You can play as a guest, create an account with an email address and password, or sign in with Google. Firebase Authentication stores your email address and a unique user ID. Guest play does not create an account.
Game progress: Coins, unlocked submarines and items, and your game progress. Signed-in players have this saved to Cloud Firestore so it carries over between devices. Guest progress stays on your device.
Purchase records: When you buy an item or subscription, Google Play provides the product ID and purchase confirmation. We keep a record of each purchase in your account so your items and VIP status can be restored.
Advertising identifier: Google Mobile Ads uses your device's advertising ID to show ads and limit repeated ads. You can reset or delete it in your Android settings.
Device settings: Sound and haptic (vibration) preferences are stored on your device only.

2. What we do not collect

We do not collect your precise location, contacts, photos, microphone audio, or payment card details. Card and billing details are handled only by Google Play.

3. How we use information

To run the game, sign you in, and keep your progress, purchases and VIP status synced.
To show ads and to prevent abuse of the game economy.
To answer support and data requests.

4. Third-party services

The app uses these Google services. Each one handles data under its own privacy policy:

Google Mobile Ads (AdMob): banner, interstitial and rewarded ads. Google Privacy Policy
Firebase Authentication and Cloud Firestore: account sign-in and cloud save.
Google Sign-In: optional Google account sign-in.
Google Play Billing: in-app purchases and subscriptions.

5. Permissions

The app asks only for the INTERNET permission (to connect to sign-in, cloud save and ads) and VIBRATE (for haptic feedback).

6. Children's privacy

Submarine Runner is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has given us personal information, contact us and we will delete it.

7. Data retention and deletion

We keep account and cloud save data for as long as your account exists. You can ask us to delete your account and all associated game data at any time.

To request deletion: email tcnthecraftnest@gmail.com with the subject Data Deletion Request - Submarine Runner, and include the email address you signed in with. We will delete your Firebase account and Cloud Firestore data within 7 business days and confirm by email. Guest progress can be removed by uninstalling the app or clearing its storage. Subscriptions must be cancelled in Google Play; deleting your data does not cancel them.

8. Security

Data sent between the app and our services uses HTTPS/TLS encryption. Access to cloud data is limited to the signed-in account that owns it.

9. Changes to this policy

We may update this policy. The updated version will be posted on this page with a new effective date.
