DS2 encrypts your files in the browser before they leave your device. Not even we can see what you're sending.
No subscription. Pay only for what you send. $0.01 per 100 MB.
Three steps. Your files never travel unencrypted.
You choose a password. DS2 uses it to encrypt your files locally — before a single byte is uploaded. Your password never leaves your device.
Only encrypted data reaches our servers. We store the ciphertext and send your recipient a secure link. We cannot read what you've sent.
Your recipient enters the password (shared separately) and DS2 decrypts the files locally in their browser. No plaintext ever touches our servers.
Every architectural decision was made to minimise what we know about you.
Not just file contents — your filenames and notes to the recipient are encrypted too. Our servers store encrypted blobs, not readable metadata.
Your address book entries are individually encrypted with your key. We store ciphertext. You hold the key.
Files are deleted from storage immediately after download confirmation or when they expire — whichever comes first.
$0.01 per 100 MB. No monthly fee, no seat licences. Top up your balance and spend only what you use.
Built on the Web Crypto API — a standard available in all modern browsers. No plugins, no native app required.
Recipients can send files back to you through the same transfer thread, without needing to create an account.
We cannot read your files. We cannot read your filenames. We cannot read your messages to recipients. This is not a policy — it is an architectural constraint. The encryption key is derived from your password and never transmitted to our servers.
