Small, inspectable runtime

Licenses

CupTune uses reusable interface components and browser platform APIs; no third-party product library or external font ships in v1.

CupTune source and content

Original HTML, CSS, JavaScript, SVG brand work and authored recipes. All rights reserved unless a file says otherwise.

Interface components

The shell, controls, result, table, legal, discovery and advertising patterns are maintained with CupTune and included in its deterministic build.

Browser APIs

IndexedDB, Service Worker and optional Screen Wake Lock are web-platform APIs supplied by the browser. Optional capabilities degrade without blocking the core workflow.

Provider code

Self-hosted Umami and Google AdSense are separate provider surfaces governed by their own notices. AdSense is not requested while every ad unit id is empty.
