1. Basic Approach

DUSTLINE App Development Division develops mobile apps with a privacy-first approach. We aim to collect only the data needed to provide, maintain, and support each product.

2. Website Data

This website may generate standard technical logs such as access time, requested page, browser type, and approximate network information. These logs are used for security, reliability, and abuse prevention.

3. Mobile Apps

Each mobile app will publish its own App Store privacy information and support notes before release. If an app uses advertising, purchases, analytics, notifications, cloud sync, or device permissions, the relevant disclosures will be provided in the app and store listing.

4. Support Contact

When you contact us for support, we may receive your email address, app name, device or OS version, and the message you send. Please do not include sensitive personal information unless it is necessary for the support request.

5. Contact
