🔒

End-to-End Encryption

Files are encrypted before leaving your device. Only your recipient can decrypt and access them.

⏱️

Auto-Destruct

Files delete automatically after download or time expiration. No residual data remains on servers.

🚫

Zero Knowledge

We cannot access your files. Our servers only store encrypted data we cannot read.

🔍

No Metadata Logging

We don't log IP addresses, file names, or transfer details. Completely anonymous transfers.

How Our Security Works

HTTPS Transport

All transfers use TLS 1.3 encryption, protecting data in transit from network eavesdroppers.

At-Rest Encryption

Files are encrypted while stored on our servers using AES-256 encryption standards.

One-Time Links

Each transfer generates a unique, unguessable URL that expires after use.

Secure Deletion

Files are overwritten before deletion, preventing forensic recovery of deleted data.

How to Transfer Files Securely

1

Encrypt & Upload

Select your files and upload. Files are encrypted in your browser before transmission to our servers.

2

Share Secure Link

Receive an encrypted link. Share it through any channel - email, chat, or encrypted messaging.

3

Auto-Delete Confirmation

Once your recipient downloads, files are immediately and permanently deleted from our infrastructure.

Security FAQ

What encryption do you use?
We use AES-256 encryption for file storage and TLS 1.3 for data in transit. This is the same encryption standard used by banks and military organizations.
Can Realtime Sender access my files?
No. We operate on a zero-knowledge architecture. Your files are encrypted before reaching our servers, and we don't have the keys to decrypt them.
What happens to files after transfer?
Files are permanently deleted immediately after successful download. They are overwritten with random data before deletion to prevent recovery.
Is this HIPAA/GDPR compliant?
Our security practices align with HIPAA and GDPR requirements for data protection. However, you should consult with your compliance officer for your specific use case.
Are transfers logged?
We maintain minimal logs for service operation only. We don't log IP addresses, file names, or transfer contents. Logs are automatically purged after 7 days.
