Security First
We can't read your files. By design.
Client-Side Encryption
AES-256-GCM happens entirely in your browser via the WebCrypto API. The raw file never touches our servers.
Key in URL Fragment
The decryption key lives after the # in the URL. Browsers never send fragments to servers.
Direct to EU Storage
Encrypted blobs upload straight to Hetzner Object Storage in Helsinki, Finland via presigned URLs. Our API never handles file data.
Auto-Delete
Transfers auto-delete. Free: up to 7 days. Paid: up to 30 days. Your files don't linger on the internet forever.
A note on browser-based encryption
While SecureEU encrypts files entirely in your browser, browser extensions can potentially observe page content. For maximum confidentiality — especially with sensitive documents — consider using our desktop app, which runs in its own process with no extension access.
SecureEU Desktop
Same end-to-end encryption, same servers — but running as a standalone Windows application. No browser extensions, no tabs, no distractions. Drag & drop your files and get a secure link in seconds.
