FileFly was built so your files stay yours. Everything happens between your own devices — there's simply nowhere else for your data to go.
Your files travel directly from one phone to the other. They are never uploaded to FileFly, the cloud, or anyone else.
There's no sign-up and no login. FileFly doesn't know who you are and never asks for your email or phone number.
No analytics that follow you, no advertising SDKs, no selling data. Nothing about your transfers leaves your devices.
Discovery and transfers happen only on your local WiFi. Turn WiFi off and FileFly simply goes quiet.
