Privacy Policy

Last updated: February 8, 2026

Overview

ZapDrop is designed with privacy as a core principle. We do not collect, store, or have access to your files. All transfers are end-to-end encrypted and occur directly between devices.

What We Don't Collect

  • Your files: Files are never uploaded to or stored on our servers
  • File contents: We cannot see what you transfer
  • Personal information: No account or login required
  • Location data: We don't track where you are
  • Contacts: We don't access your contacts

How ZapDrop Works

When you transfer a file:

  1. A temporary session is created on our relay server
  2. The session contains only a random ID - no file data
  3. Files are encrypted on your device before transfer
  4. Encrypted data passes through the relay to the recipient
  5. The recipient decrypts the file on their device
  6. Sessions automatically expire after 10 minutes

Data We Process

Our relay server temporarily processes:

  • Session IDs: Random identifiers to match senders and receivers
  • Encrypted data: Passes through but cannot be read by us
  • IP addresses: For rate limiting only, not stored

All session data is automatically deleted after 10 minutes or when the transfer completes.

Encryption

ZapDrop uses industry-standard encryption:

  • TLS 1.3 for all connections
  • End-to-end encryption for file transfers
  • Keys are generated fresh for each session
  • We never have access to encryption keys

Third-Party Services

ZapDrop uses minimal third-party services:

  • Fly.io: Hosts our relay server
  • Vercel: Hosts our website
  • Upstash Redis: Temporary session storage (encrypted)

We do not use analytics, tracking, or advertising services.

Children's Privacy

ZapDrop does not knowingly collect any information from children under 13. The app is rated for all ages and requires no personal information to use.
