2. Audience and supervised use
Dulang is aimed at children and must be set up and supervised by a responsible adult. The parental PIN available in the app is a control tool exclusive to the guardian, it is not accessible to the child.
3. Data stored on the device
Favorites, playback history, child profiles, theme preferences, and the parental PIN are stored locally on the device. This data is not sent to our servers as a browsing profile. The parental PIN is stored securely (encrypted storage on the device).
4. What we do not collect
Dulang does not collect personal data from children. We do not display advertising in the app. We do not track behavior for advertising purposes. We do not sell data.

6. Use of the YouTube API
Dulang uses the YouTube API to display videos, thumbnails, and metadata from curated channels. The audiovisual content belongs to the creators and the YouTube platform. Playback occurs inside the app, the child does not freely browse the internet through Dulang. See Google's Privacy Policy at policies.google.com.
7. Minimum operational data
For catalog synchronization, our infrastructure (Supabase) may process minimal technical data, such as app version and anonymous device identifiers, exclusively to operate the service. This data is not linked to personal identity.
