Our Commitment to Your Privacy

End-to-End Encryption

Every file shared through SendFiles.in is protected using military-grade 256-bit encryption during transit. This ensures that your data remains unreadable to ISPs, hackers, or any third party as it streams directly from your browser to the recipient's browser.

We leverage Cloudflare's world-class infrastructure to provide a secondary layer of protection against DDoS attacks and unauthorized access attempts at the edge.

Zero Server Storage & Non-Custodial Architecture

Unlike mainstream cloud storage providers, SendFiles.in never stores your files on intermediate servers or remote hard drives. Our pure Peer-to-Peer (P2P) WebRTC architecture streams data live between devices. Once the transfer completes and browser tabs close, zero file data remains on our network.

Because your files never touch a server disk, they cannot be leaked in cloud database breaches, subpoenaed from hosting providers, or tracked by third parties.

Zero-Knowledge Infrastructure

We do not require users to create accounts or provide identifying information to share files. We do not track who sends which files, and we do not log user activities beyond what is necessary for basic server maintenance and load balancing.

  • No IP tracking of downloaders.
  • No metadata mining of uploaded files.
  • No third-party data sharing (we have no data to sell).
