Focused products
Clear interaction, responsive experiences, and features that serve the product rather than marketing noise.
Mobile software studio
Software with focus.
Vanguard Knight builds focused mobile applications with careful attention to interaction, performance, and privacy.
Product
Hang Drum
A touch-based virtual handpan instrument for playing, recording simple melodies, and shaping a calm visual and ambient experience.
Principles
Built with restraint.
The website is intentionally lightweight and tracker-free. Product behavior is documented by distribution so privacy disclosures can match the software that is actually shipped.
Local by default
Hang Drum keeps preferences, saved melodies, and unlock state in app-local storage unless a third-party service is required for a specific feature.
Transparent boundaries
Advertising and store billing are handled by distribution-specific providers and are described separately in the privacy policy.
