Client-side encryption with one-time download enforcement
Your file is encrypted with AES-256-GCM in your browser before upload. The server receives only encrypted bytes—mathematically impossible to read without the key.
The decryption key lives in the URL fragment (#key=...). Browsers never send fragments to servers, making it impossible for us to decrypt your file.
Files can be downloaded exactly once. After the first download, the encrypted blob is permanently deleted from our servers and the link becomes invalid forever.
Uploaded files automatically expire after 24 hours if not downloaded. This ensures temporary sharing without long-term storage or lingering traces.
