Privacy Policy

Zelvra Labs ("we", "us", or "our") operates the Cluster app and any other apps we publish under the Zelvra Labs developer account on Google Play. This Privacy Policy explains what information we collect, how we use it, and your choices.

Information We Collect

Our apps are designed to be lightweight. We do not collect your name, email address, or any account information directly. The following may be collected automatically:

• Usage data — general information about how you interact with the app (e.g. sessions, crashes), collected via Google Play's built-in analytics.
• Device information — device type, operating system version, and similar technical details used to diagnose issues.
• Advertising data — our apps may display ads served by third-party ad networks (such as Google AdMob). These providers may collect data including your device's advertising ID to serve relevant ads. Please refer to their privacy policies for full details.

How We Use Information

Any data collected is used solely to:

• Operate and improve our apps
• Diagnose crashes and fix bugs
• Display advertisements through third-party ad networks

We do not sell your personal data to third parties.

Third-Party Services

Our apps may use third-party services that have their own privacy policies. These may include:

• Google Play Services
• Google AdMob

We encourage you to review the privacy policies of any third-party services used within our apps.

Data Storage

Game progress, streaks, and puzzle completion data for Cluster are stored locally on your device only. We do not upload this data to any server.

Children's Privacy

Our apps are not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe your child has provided us with personal information, please contact us and we will take steps to delete it.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated date. Continued use of our apps after changes constitutes your acceptance of the updated policy.
