Arca: Personal Drive

Arca is a personal drive for your own devices. Your files, photos and music live on a hub you run yourself, and every device keeps complete local copies that stay in sync in both directions. No account, no public relay, no telemetry.

WHAT YOU GET
• Complete local copies: the files on your iPhone are real files, never placeholders. Open them offline.
• Two-way sync: edits made on any device reach the others. When two devices edit the same file, both versions are kept.
• Version history: restore older versions or deleted files from the hub's history.
• Your music, everywhere: turn any folder into a music library. Artists, albums, covers and playlists are built from your own audio files. Play it on your computer or in a browser, and on Android, including Android Auto. On iPhone, browse the whole library and open any track in the player you prefer.
• Playlists that are just files: playlists are standard .m3u8 files that sync like everything else and keep working outside Arca.
• Photo uploads: send photos and videos from your library to a shared folder on your hub. Your originals stay in Photos, and Arca never deletes them from the system library.
• Share to Arca: send a file from another app into any folder you sync.
• Private by design: pairing uses single-use six-digit codes between your own devices. Nothing leaves your network unless you decide it should.

HOW IT WORKS
Arca needs a hub, which is a computer or server you control and which runs the free Arca hub software. Pair your iPhone with a short code and choose which shared folders to keep on this device.

Arca is free for personal and non-commercial use.
