About our technology and security

What makes Retyc secure and different from other file sharing services?

What we do better than anyone else

End-to-end encryption

Your files are encrypted before upload and can only be decrypted after download. Noone else can access them, not even us.

Data residency in EU

Your data never leaves the European Union. They are stored on sovereign infrastructures certified HDS (Hébergement de données de santé — Hosting of health data) for total peace of mind. We are not subject to US laws like the CLOUD Act.

Private key management

Encryption keys are under your control, ensuring zero external access to client data.

No third-party tracking

No external trackers, or cookies. Security is built into the product, by design.

Not just access control

Access control is not enough. With use, even if someone gets access to your encrypted files, they can't read them without the encryption keys.

Open source cryptography

Our cryptographic implementations are open source and can be audited by anyone. Transparency builds trust.

Do you really need to trust others?

Most storage providers claim to keep your data safe, but in reality, they have full access to your files and can share them with third parties.

WeTransfer can use your data
By using WeTransfer, you grant them a free license to use your files to "improve their services"
Dependence on GAFAM
Many third-party services rely on major cloud providers (AWS, GCP, Azure). Some like to believe that hosting data in a European data center ensures digital sovereignty — but that’s pure illusion. These providers remain subject to U.S. laws, including the CLOUD Act.
Weaker protection against hackers
Centralized storage systems without end-to-end encryption are prime targets for cyberattacks.

Encryption at rest and in transit

Most platforms claims to use encryption, but they only encrypt data in transit and at rest on their servers. This means they can still read your files.

Encryption in transit
It's just standard practice to use TLS to encrypt communication while it's being sent over the internet... Everyone uses it with HTTPS. Are you reassured now?
Encryption at rest
Files are encrypted on the server, but the provider has the keys to decrypt them. This means they can access your data whenever they want. Not very comforting, is it?
Just check the facts
Encryption without control is not privacy. Just look their pages about security and privacy policies... lots of words but no real guarantees.
