How does C1 sync between computers?

Learn how C1 transfers encrypted slices over Bluetooth or USB, resumes interrupted sync, switches transports, and resolves multi-computer conflicts safely.

How does C1 sync data?

The OneMira C1 AI Voice Recorder & Note Taker transfers encrypted audio slices to one paired computer at a time over the documented local connection. OneMira transcription runs on that computer; internet may still be needed for setup, model downloads, or third-party AI services.

*Note: Similar to Bluetooth headphones, C1 connects to only one computer at a time. A second computer will connect automatically once the first computer is disconnected or out of range.*

Audio storage and space: You choose in OneMira Settings whether to retain original audio. Temporary device-side transfer slices are separate from this choice. Retained recordings use storage in addition to text context.

How does the transfer work?

The C1 automatically switches between a fast USB-C cable connection and a convenient wireless Bluetooth connection to copy your files. You do not need to configure anything—the transfer happens smoothly in the background.

USB-C Cable Sync

High-speed transfer Connect C1 to your computer with a USB-C cable for faster transfer of long recordings.

Wireless Bluetooth Sync

Wireless sync When C1 is near your computer, it automatically transfers your short recordings and notes in the background wirelessly so you can keep working.

Smart Sync Features:
  • Cable First: When you plug in the USB-C cable, C1 immediately switches to the faster cable connection to save battery and sync files faster.
  • Safety Protection: A brief safety delay prevents file errors if the cable is plugged in and out quickly by accident.
  • Pick Up Where You Left Off: If you unplug the cable during sync, C1 can continue over its paired Bluetooth connection from the previous transfer point.
  • Smart Wireless Adjust: C1 adjusts the wireless transfer rate as connection conditions change. Keep it near the paired computer while syncing.

How does C1 protect my notes?

To keep your notes accurate and up to date, the OneMira app includes built-in safeguards that prevent file confusion, even if you sync C1 with more than one computer.

Built-in data safeguards:
  • Secure Ownership: The app verifies your C1's unique identity before every transfer, ensuring your recordings are only sent to your authorized computers.
  • Smart Updates: The app compares files on your device and computer to ensure only the latest additions and changes are synced, avoiding duplicates.
  • Conflict handling: C1 carries encrypted text snapshots between computers; edits happen on the computers. If both sides changed the same logical file, the receiving app asks whether to keep its local version or the snapshot carried by C1. Non-conflicting files continue syncing.
  • Power-Loss Protection: If a transfer is interrupted, the app uses its last saved state to recover. Reconnect C1 and check that sync completes before relying on the transferred files.
  • Storage housekeeping: C1 removes eligible temporary files and old logs according to its retention rules. If free space reaches the protected threshold, it stops accepting new capture data and reports the condition instead of claiming space is always available.
