The Problem with Traditional File Sharing

Every time you use a traditional file sharing service, you leave traces:

Files stored on servers (sometimes indefinitely)
Metadata logged (who, when, what, where)
Account information retained
Activity patterns analyzed

Even "temporary" sharing links often leave data behind.

ZeroSend's Zero-Footprint Approach

No File Storage

Unlike traditional services, ZeroSend never stores your files:

Traditional: Your Device → Server Storage → Recipient Device
ZeroSend:   Your Device ←——————————————→ Recipient Device

Files stream directly from sender to receiver through an encrypted WebRTC data channel.

No User Accounts

No registration required
No email addresses collected
No personal information stored
No user profiles to breach

Ephemeral Connections

6-digit room codes exist only in memory
Codes expire after 5 minutes
No persistence after browser tab closes
No logs, no records, no trace

Minimal Signaling Data

Our signaling server only facilitates the initial connection:

Relays WebRTC handshake messages temporarily
Never sees file contents (encrypted)
Discards all data immediately after use
No logging of any kind

Technical Implementation

WebRTC Data Channels

Files are transferred through RTCDataChannel:

Connection established via signaling
DTLS encryption activated automatically
Files chunked and transmitted directly
Connection closed, data gone

Memory-Only Processing

Files processed in browser memory
No disk caching
No temporary files
Close the tab, data disappears

What We Don't Know

ZeroSend is designed so that we literally cannot know:

What files you transfer
Who you transfer to
When transfers happen (no logging)
Your identity or location

Comparison

Data Point

Traditional Services

ZeroSend

File contents	Stored on servers	Never touches servers
User identity	Required	Not collected
Transfer logs	Kept for years	None exist
Metadata	Extensively tracked	Not applicable

The Result: True Privacy

When you use ZeroSend:

Your file exists only on your device and the recipient's
The transfer happens through encrypted P2P connection
Once complete, no evidence of the transfer exists anywhere
Even we cannot prove the transfer happened

Conclusion

Privacy isn't just about encryption—it's about architecture. ZeroSend is built from the ground up to ensure that your file transfers leave no digital footprint, anywhere, ever.
