Share files and messages worldwide, securely and easily.
Your files are encrypted before they leave your device.
We can't see what you send - nobody can, except the person you share with. No signup form - verify your email and we create a temporary account that deletes itself, and everything you sent, after 3 days.

What you can do with GCN.ONE
From a quick anonymous transfer to a delivery you can prove - the same encryption protects every file.
Anonymous quick send
Verify an email, drop a file, share a link. Recipient downloads the file, then it’s gone. The temporary account goes with it after 3 days.
Registered users get an inbox
Every registered account gets a dedicated Inbox and Sent view, so you can see everything you've sent and received in one place.
Proof of Delivery
Proof that your file arrived, not just that you sent it. For when “I sent it” has to be more than your word.
Every link open and every download start is recorded, with a timestamp.
A cryptographically signed delivery certificate for any delivered file, on request.
Anyone can check a certificate - no GCN.ONE account needed.
Who it's for
Built for the moment a file has to arrive - and you have to be able to prove that it did.
Law firms & notaries
Contracts, filings, evidence. You get a signed, timestamped receipt that the other side opened the file and started downloading it - and we have nothing to hand over if anyone asks, because we can't read it.
Accountants & tax advisors
Client records and year-end filings stay confidential end to end, with a delivery record that holds up when a deadline is disputed.
Clinics & healthcare
Patient files move between practices without our servers ever seeing the contents, and every access is written to the sender's log.
Freelancers & agencies
Deliverables for clients. “I sent it on the 3rd” becomes a certificate anyone can check, instead of a claim buried in an email thread.
Need more than a single transfer?
Plans starting at free. Larger files, more transfers per month, and longer file retention.
Zero Access
Data is stored encrypted.
European Jurisdiction
Infrastructure and data hosted in the EU, operator in the UK.
No ads, no data resale
No ads. We don't sell or broker your data.
Enter your email to get started. We’ll send you a verification link and set up a temporary account that expires in 3 days.
