NIXLIGHT TECHNOLOGY LIMITED · Last updated: May 2026

NIXLIGHT TECHNOLOGY LIMITED ("NIXLIGHT", "we", "us", or "our"), registered in Hong Kong S.A.R., operates the mobile applications Japanese Numbers Drill and SoloScanner, as well as the website nixlight.com. This Privacy Policy explains how we collect, use, and protect your information.

1. Information We Collect

Our apps are designed with a privacy-first approach. We collect minimal data:

Usage and analytics data — anonymous usage statistics (e.g. session counts, feature usage) collected via Apple App Store and Google Play Store frameworks to help us improve the apps.
Crash reports — anonymised diagnostics to identify and fix technical issues.
Advertising identifiers — device identifiers may be used to serve relevant ads where applicable, as described in each app's App Store / Play Store privacy label.

We do not collect: your name, email address, location, contacts, photos, or any personally identifiable information through the apps themselves. All user-generated content (scans, practice progress) is stored locally on your device only and never transmitted to our servers.

2. How We Use Information

To maintain and improve app performance and stability.
To understand aggregate usage patterns and prioritise new features.
To comply with legal and regulatory obligations.

3. Third-Party Services

Our apps may use third-party SDKs provided by Apple and Google for analytics, crash reporting, and advertising. These services operate under their own privacy policies:

4. Data Retention

Anonymous analytics data is retained for up to 24 months for the purpose of product improvement. No personal data is stored on our servers.

5. Children's Privacy

Our apps are rated 4+ and are suitable for all ages. We do not knowingly collect personal information from children under the age of 13. If you believe we have inadvertently collected such information, please contact us immediately.

6. Your Rights

Depending on your jurisdiction, you may have rights to access, correct, or delete data we hold about you. Since we do not collect personally identifiable information, there is typically no personal data to access or delete. For any privacy-related requests, please contact us at [email protected].

7. Security

We implement industry-standard security practices. All app data remains on your device and is never transmitted to external servers. We regularly review our practices to maintain appropriate protections.

8. Changes to This Policy

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