Nuts & Bolts: Screw Puzzle

Legal Information & Privacy Center

Last updated: June 14, 2026 | Developer: SoftTech Service

SoftTech Service ("we", "our", or "the app") respects your privacy and is committed to protecting data security. This Privacy Policy details how data is handled when you download, install, and play Nuts & Bolts: Screw Puzzle.

1. Information Collection and Use

We prioritize user privacy and adhere to data minimization principles. We do not collect, store, or share any personal identity information.

Gameplay Storage

The game stores gameplay progress, achievements, coin count, and diamond count locally on your device via standard browser localStorage. No personal or gameplay database is uploaded to remote servers. This ensures you can play the game offline with full state retention.

Important: Clearing your app storage, cache, or webview data will reset your local gameplay progress, coin balance, and unlock states.

2. Device Permissions

To run the hybrid puzzle canvas securely and offline, the application requests the following device permissions:

Permission	Description	Purpose
Internet Access	`android.permission.INTERNET` / iOS NSNetwork	Strictly required to run the local ephemeral asset web server (http://localhost) to render the HTML5 Construct 3 game widget offline. No external server tracking is done.

3. Third-Party Services & Ad Networks

The application integrates Google AdMob for advertisement monetization. Google AdMob may collect and use anonymous device identifiers or advertising IDs to serve relevant advertisements.

We recommend reviewing Google's policies for a complete breakdown of data collection and choices: Google Privacy & Terms for Advertising.

4. Children's Privacy

Our game does not collect personal data from anyone, including children under the age of 13. We adhere to the Children's Online Privacy Protection Act (COPPA) guidelines and do not track personal identifiers.
