NOVA STRIKER Privacy Policy

Last updated: August 2, 2026

NOVA STRIKER (the "App") is provided by Join Circle LLC ("we", "us"). This policy explains how information is handled in the App.

1. Information We Collect

Information stored only on your device

The App does not require an account, and we do not directly collect personal information such as your name, email address, or phone number. Settings, achievements, and the on-device ranking are stored only on your device.

Information sent for the global ranking

The App has a global ranking feature. When a game ends, the following is sent to our server:

Your player name and score are shown publicly to other users on the global ranking screen. Please do not use your real name, contact details, or anything else you would not want made public. You can change your player name at any time in the Settings screen.

We do not collect location, contacts, photos, or files on your device.

Abuse prevention

To prevent fraudulent score submissions, the App uses Google Firebase App Check. This verifies that requests come from a genuine copy of the App and does not identify you personally.

Usage analytics

To improve the service, the App uses Google Firebase Analytics to collect anonymous usage data. This relates to app interactions, such as starting and finishing plays, selected difficulty, stages reached, achievements unlocked, ad views, ranking screen views, and sharing results.

We do not send player names, scores, or any personally identifiable information to analytics. The data is used solely for statistical analysis and is never sold to third parties.

Information collected by third parties for advertising

The App uses Google AdMob to display ads. AdMob may collect advertising identifiers (IDFA / AAID), IP address, and device information for ad delivery and fraud prevention. See:

2. Ads and Consent

3. Children's Privacy

The App is not directed at any specific age group and does not knowingly collect personal information from children under 13.

4. Data Storage and Deletion

Data on your device

Settings, achievements, and the on-device ranking are stored only on your device. Deleting the App deletes all of this data.

Global ranking data

Records submitted to the global ranking are stored on our server. The ranking keeps only the top 300 entries, so a record that falls below that threshold is deleted automatically.

If you would like your own record deleted, please contact us at the address below and include the "ID" shown in the App's Settings screen. We will verify and delete it. The ID is required because more than one player may be using the same player name.

Records that remain in the top rankings are stored without a time limit.

This "ID" is lost when you delete the App. If you may want to request deletion later, please make a note of it before deleting the App. The ID is a random value generated on your device and is not linked to any device identifier or to information that identifies you.

Analytics data

Usage analytics data is retained for up to 14 months and is then deleted automatically.

5. Where Data Is Stored and International Transfers

Global ranking data is stored on Amazon Web Services (AWS) servers in the United States. Information sent from any country, including your own, is transferred to the United States.

We also use Google Firebase Analytics and AdMob, so information is additionally handled on servers in the countries and regions those services designate.

6. For Users in the European Economic Area (EEA) and the UK
