No client software, no VPN, no FTP credentials to circulate. Open a tab, drop the file, send a link that expires on its own.
“Enterprise-grade confidentiality with consumer-grade effort.”
For teams replacing ftp, sftp hand-offs and ad-hoc email attachments with something people will actually use.
Encryption runs in the browser using modern web cryptography. Nothing to install for you or the recipient.
Passphrase, expiry within 24 hours maximum, optional view budget, watermarking and one-click revocation.
An append-only record of creation, first use and revocation for each transfer.
For recurring exchanges, replace repeated links with an encrypted space where members hold their own sealed keys.
Chunked, resumable uploads with verification, so large transfers do not fail silently.
Passkeys, TOTP and reviewable device trust protect the account behind the transfers.
FTP and SFTP persist because they handle big files and because someone set them up years ago. They also mean shared credentials, servers nobody patches, plaintext on the host and no meaningful audit of who fetched what. A browser-based encrypted transfer replaces all four problems at once.
If you send files to the same partner every week, stop creating links. Give them membership of an encrypted space with their own sealed key: access is continuous, revocation is instant, and the audit trail lives in one place.
A secure tool that is slower than the insecure habit loses. Fast uploads, no recipient sign-up and a link that just works are the reason people stop reaching for consumer alternatives.
Recurring exchanges are best handled with shared encrypted spaces and Live Clone mirroring of a local folder, which keeps material synchronised without manual sends.
Yes — send and receive from iOS and Android, with the same client-side encryption.
No. Files are encrypted on your device with XChaCha20-Poly1305 before the upload starts, using keys derived locally with Argon2id. Our servers hold ciphertext only, so there is no preview, no scanning and no staff view of your transfer.
No. They open the link in any browser, type the passphrase you shared separately, and the file is decrypted locally on their machine. Nothing to install, nothing to sign up for.
Public share links always expire within 24 hours at most, and you can make them shorter, limit the number of views, or revoke them instantly. Expiry is enforced by the system, not by a reminder.
Uploads are chunked, resumable and verified after upload, so multi-gigabyte transfers survive a dropped connection, a closed laptop or a hotel network. You resume instead of starting again.
Yes. The free plan includes 1 GB with exactly the same zero-knowledge architecture as paid plans, so you can test a real client hand-off before paying anything.
Because we cannot read your data, we cannot reset it for you. Each account creates a Recovery Kit — a printable PDF with a QR code — to store offline. That is the same property that keeps anyone else, including us, out of your account.
Start free with 1 GB. Zero-knowledge encryption from the first upload — no admin override, no AI scanning, no plaintext on the server.
