Short answer: nothing. CYPHER runs entirely on your local WiFi network. Your files, your clipboard, your PC data — none of it ever reaches an external server.
There is no account. No sign-up. No analytics beacon. Uninstall CYPHER and it's like it never existed.
All traffic stays on your local network. CYPHER has no backend to send your data to.
No email, no profile, no database entry. You are anonymous by default.
No crash reports, no usage stats, no pings home. CYPHER does not know you exist.
Nothing persists externally. Delete the app and there is no trace of you anywhere.
No accounts. No drivers. No configuration files. Just download and connect.
Grab the .exe for Windows and the .apk for Android from the releases page below.
Enable your phone's mobile hotspot and connect your PC to it — just like any WiFi network.
CYPHER on your PC displays its address. Type it into the phone app. Takes 5 seconds.
A 6-digit code confirms the link. Enter it once — your devices remember each other after that.
Yes, completely. Every byte travels directly between your phone and PC over your local WiFi. Internet is never required for any feature.
On a 5GHz hotspot you can expect 20–50 MB/s. A 1GB file transfers in about 30 seconds. Much faster than Bluetooth, comparable to USB.
Only devices you explicitly pair using the 6-digit code. Random devices on the same network cannot connect without the code.
All of them. CYPHER transfers raw bytes — documents, 4K videos, executables, zip archives. No restrictions on type or size.
Yes, your PC needs to be on and running the CYPHER app. You can remotely sleep or shut it down via the phone when you're done.
Yes. No premium tier, no subscription, no feature gates. Everything is free forever. It's open source on GitHub.
Stop emailing files to yourself. Stop hunting for USB cables.
Just CYPHER.
