Your Personal Media Vault for Life Off the Grid.

We live in a world that demands constant connectivity, yet the most enriching experiences often happen where the signal fades—on a remote trail, a transatlantic flight, or a countryside retreat. StreamCache reimagines media portability. It is not merely a downloader; it is a digital cargo system that intelligently curates, compresses, and stores your favorite videos, music, articles, and podcasts for zero-connectivity consumption.

Inspired by the need to decouple entertainment from instant bandwidth, StreamCache acts as a predictive librarian. It learns your viewing habits, syncs during low-usage hours, and delivers a seamless offline library that feels as responsive as if you were streaming live—without the data drain.

Traditional offline modes are afterthoughts—clunky, fragmented, and platform-locked. You subscribe to five services, but each demands its own app, its own cache, and its own patience. StreamCache consolidates this chaos. Think of it as a universal courier for content: you specify the destination (your device), the cargo (your favorite channels or feeds), and the schedule (overnight, while charging, or on demand).

This repository encapsulates the core engine that powers that vision. It is open, extensible, and built for the modern nomad.

• Analyzes your viewing history across integrated platforms.
• Predicts content you will want before you leave the network.
• Filters by genre, duration, file size, and freshness.

• Automatically selects optimal codec and resolution based on available storage.
• Preserves metadata (chapter markers, subtitles, descriptions).
• Batch processing for series or playlists without duplication.

• Connects to YouTube, Vimeo, SoundCloud, RSS feeds, and personal file servers.
• Unified queue management across all sources.
• One‑click import from share sheets and browser extensions.

• Tiered storage: Hot (SSD) for recent, Warm (SD card) for weekly, Cold (cloud/archive) for long‑term.
• Automatic cleanup of consumed content with optional retention rules.
• Transcoding on the fly for devices with low disk space.

• Fluent design from 4‑inch phones to ultrawide monitors.
• Dark mode, sepia mode, and high‑contrast accessibility themes.
• Voice‑activated commands for hands‑free queueing while driving or cooking.

• Interface fully translated in 27 languages.
• Content search supports Chinese, Arabic, Devanagari, and Cyrillic scripts.
• Regional date/time/number formats respected throughout.

• Runs scheduled tasks using a lightweight background daemon.
• No user intervention required once initial preferences are set.
• Priority mode for critical downloads (e.g., an hour‑long movie before a flight).

• All processing occurs locally on your device.
• No central tracking of what you cache.
• Optional end‑to‑end encryption for synced metadata across your own devices.

StreamCache is designed to be low‑friction. Once you have the runtime environment ready, the initial setup takes under three minutes.

• A modern OS (Windows 11, macOS 14+, Linux kernel 6.2+)
• At least 500 MB of free RAM for the daemon
• Optional: a stable internet connection for the initial feed discovery

1. Download the latest release for your platform.
2. Launch the daemon – it will guide you through adding your first content source.
3. Open the web dashboard (default port :8080) or the native app.
4. Subscribe to a channel or paste a link. StreamCache handles the rest.

No account creation required. No background telemetry. The vault is yours.

• Road Trip Immersion: Curate a playlist of documentaries for a 10‑hour drive. StreamCache pre‑fetches chapters, geography info, and related articles.
• Educational Off‑Grid: Teachers can push a week’s worth of video lessons to classroom tablets without any internet cost.
• Language Learning: Download subtitled content in two languages simultaneously for offline study.
• Archival Recovery: Migrate your entire YouTube “Watch Later” list to a local archive before a service change.

StreamCache never stores payment details, login credentials, or personal identifiers. All third‑party service logins are handled via OAuth and stored only in your OS keychain. The offline cache is encrypted at rest using AES‑256‑GCM. For added safety, you can enable automatic deletion of cached files after seven days of non‑consumption.
