Every time you drag a file into WeTransfer, Dropbox Transfer or Google Drive and hit share, the file travels to an American server where the provider can technically read it, scan it, flag it, hand it to law enforcement, or train AI models on it. WeTransfer's own privacy policy explicitly reserves the right to scan content for policy violations. Google Drive feeds Gemini. Dropbox has disclosed law enforcement data requests for years. None of this is a secret but most people simply do not think about it when sending a contract, a medical document or a client file. Before we look at the alternative: it's worth mentioning that I also already introduced you to Localsend a few weeks ago which is another great alternative for sending files locally. It's free a open-source, cross-platform file sharing tool. I's a great Airdrop alternative for any device in the local network.

Retyc is a French startup from Lyon, built by Emilien Mantel, that starts from the opposite assumption. Its tagline is "Hors de leur portée", out of their reach, and the architecture actually delivers on that. Files and their metadata are encrypted on your device before they leave it, using the AGE encryption standard, an open source, independently audited library, not proprietary in-house cryptography. By the time the data reaches Retyc's servers, it is already locked. Retyc itself cannot read what you sent, cannot hand the content to a third party and has explicitly committed to never integrating AI into the platform.

The zero-knowledge model goes further than most "secure" file transfer services. Many competitors encrypt files in transit and at rest, which sounds reassuring until you realise that the provider still holds the keys. Retyc's model ensures the provider never has the keys in the first place. Even the metadata, file names, sizes, sender and recipient details, is encrypted before upload.

The entire infrastructure is hosted in France, fully under EU jurisdiction and GDPR compliance is built into the architecture rather than bolted on as a checkbox.

The comparison that matters is not just against WeTransfer. It is against every file sharing tool that you or your organisation currently uses by default because it came bundled with something else. Google Drive sharing links, Outlook attachments previewed on Microsoft servers, Slack file uploads processed in US data centres. Every one of these is a tool that a US company has the technical and legal ability to access. Retyc's zero-knowledge model removes that ability entirely, which is especially relevant for anyone in a profession where client confidentiality is not optional.

It launched its public beta on March 24, 2026 and is still in early access, so treat it accordingly. Test it with non-critical files first, verify the full sender and recipient experience, and evaluate whether the current free tier limits work for your use case before integrating it into sensitive workflows. The architecture is solid and the approach is exactly what the European sovereign software stack at the file transfer layer is needing.
