file.sparrowx.net • Ephemeral Zero-Disk Drop & 10GB Sovereign Vault
Files are encrypted with AES-GCM in your browser RAM before transfer. The moment you close this tab, memory is zeroed out and destroyed.
Drag and drop file for zero-disk transfer
AES-GCM-256 encrypted • 15-minute TTL • Zero disk footprint
Every file dropped into SparrowX Drop is sealed in your browser with AES-256-GCM before a single byte leaves your device.
Send files up to 100 MB without creating an account. Payloads live strictly in volatile memory and self-destruct after download or TTL expiry.
Decryption keys stay in the URL fragment or your local passcode. Servers only ever relay opaque ciphertext—never plaintext bytes.
Need permanent CDN-backed links, download counters, and instant revocation? Switch to Vault Mode for 10 GB of free encrypted object storage.
