A LITTLE MOMENTUM

Send files

Transfer details
Encrypted SynCloud deliveryOptional three-minute safety hold after upload, selected below. Uses your current Wi‑Fi or mobile internet. Up to 10 GB per file and 10 GB per selection. Keep the app open; large files stream in encrypted 20 MB pieces without staging the whole file in browser storage; uploads resume from completed pieces after an allowed connection returns. Files above 64 MB need direct-to-disk save support (Chrome on Android or Chrome/Edge on desktop); iPhone and iPad browsers cannot save these large files directly yet. Offline destinations can accept and collect later.

Available

Undo send & optional safety hold

Enable the optional three-minute safety hold per send, or choose its default in Preferences. Existing held transfers keep their original protection. Undo removes the encrypted SynCloud copy and blocks future downloads. Once downloading has started, already fetched or saved copies cannot be remotely erased. Vault uploads are your own storage and are not held.

Available

Wi‑Fi & mobile internet

Encrypted uploads go to your private queue. Registered devices can retrieve them from anywhere. Mobile data charges may apply.

Native app needed

Bluetooth & direct Wi‑Fi

Native discovery, explicit pairing, and compatible local transports are needed. This browser release does not scan radios or transfer over Bluetooth.

Native app needed

Background & automatic Photos saving

Browsers can be suspended. Keep SyncFi open to upload, receive, or use a permitted receive folder. A powered-off device cannot receive immediately; SynCloud queue waits for it.

NO INTERNET NEEDED

Nearby Send

Send files directly over your local Wi-Fi — no internet, no mobile data, no storage used. Both devices stay on the same network. Files are encrypted end-to-end, just like cloud sends.

WELCOME TO SYNCFI

Your private network.

SyncFi moves your files, clipboard, codes and calls between your devices — encrypted end to end, with no Big Tech account watching.

Next: one switch for automatic backup.
