Privacy and processing
Your editing workflow is local-first
Timeline Studio is designed to process selected project media in the browser. This page describes the product's technical behavior; it is not a promise that the browser makes no network requests.
Local project media
Images, video and audio are selected from the user's device and represented as browser-local objects while editing. Preview rendering, waveform work, timeline operations and video composition run in the browser.
AI model downloads
Large ONNX models and browser runtimes are loaded on demand from configured hosting providers, including revision-pinned model assets. Those providers receive ordinary HTTP requests required to deliver the files. A service worker caches supported assets so repeat workflows do not need to download every model again.
Browser storage
The app uses browser storage for preferences such as interface language and for cached application or model assets. Clearing site data removes locally stored preferences and caches.
Microphone and downloads
Voice recording requires explicit browser microphone permission. Generated audio, exported video and project packages are saved through the browser's download mechanism after a user action.
Project responsibility
Users are responsible for having the rights and consent needed for uploaded media, voices, portraits and exported content, especially when creating a talking portrait or publishing a generated video.
