WITH AlterSend
E2E ENCRYPTED
Open AlterSend, share a key
No account. No install. Nothing.
Drop your files in
Any size. Drag and drop.
They receive it. Done.
Encrypted. Direct. No trace.

Three steps. That's it.

01

Pair devices

Scan a QR code or enter a short key. No accounts, no passwords, no sign-up.

02

Create a vault

An encrypted shared space visible only to your paired devices. Nothing stored in any cloud.

03

Share securely

Drop files in. They travel device-to-device, AES-256 encrypted, without touching any server.

Others get close. None go all the way.

Every tool people actually use has at least one dealbreaker. AlterSend was built to have none.
