Protect yourself, your team, and your business partners against theft, abuse, sabotage, blackmail, and espionage. Documents and files transferred securely, efficiently, and provably, wherever you and your recipient happen to be.
How it works
No signup. No software. Just your browser, and a legally signed receipt if you need one.
01
Enter your email and click the link we send you. Takes a few seconds.
02
Your file is locked right on your device before it goes anywhere.
03
We email the recipient a download link, or you copy it and share it yourself. Either way, your file stays locked and we never see the contents.
When only the facts matter
Built-in audit trail
Proofix doesn't just move your files. It documents every step, so you always have the evidence if you need it.
The moment you send, our Swiss-hosted internal time-stamping service signs a cryptographic fingerprint of your file, sender, recipient, and exact timestamp. Proof records are retained indefinitely for legal reference.
Indefinite
proof retention for legal reference
Built on trust
Your files are encrypted on your device with AES-256, the same strength banks use. With link-only sharing, only you and your recipient hold the key.
Every proof-tier send comes with a tamper-evident receipt, timestamped by our Swiss-hosted time-stamping service. Useful as delivery evidence.
Your files live on servers in Switzerland, under Swiss law. Fully compliant with European and Swiss privacy regulations.
Just enter your email and send. Your recipient needs nothing at all, just the link you give them.

Your files stay yours
Every file is locked with AES-256 in your browser before upload. When you share the link yourself, only you and your recipient hold the key. If you ask us to email the link, we briefly see the key while sending the email. Pick link-only sharing for strict key separation.
Inside Proofix
What our servers actually do with your sealed file
Stored encrypted
The sealed file sits locked in our Swiss storage. We have no key to open it.
Timestamp on fingerprint
Only a one-way hash — not the file itself — is signed by a Swiss time-stamping service, on the proof tier.
Access audit
When the link is opened or the file is downloaded, we record the event so the sender has proof of delivery.
Your file
Sealed end-to-end. Passes through our servers locked.
The key
Made on your device. Travels directly to your recipient.
Traditional vs. Proofix
Same legal weight. Seconds instead of days. No trip to the post office.
