Out of their reach
File transfer and dataroom. Encrypted. European.
The European platform for secure file transfer and encrypted datarooms. End-to-end encryption, zero-knowledge architecture, and sovereign hosting compliant with GDPR.
Features
Everything you need to transfer and collaborate
From one-time file transfers to complex collaborative datarooms. A complete platform that scales with your needs.
Secure file transfer
Send files of any size with automatic encrypted link generation. Configurable expiration, password protection, and revocation at any time.
Collaborative datarooms
Create secure workspaces for your sensitive projects. Organize your documents, invite collaborators, and precisely control who accesses what.
Automatic versioning
Each update creates a new version without overwriting previous ones. Complete history, easy restoration, and zero data loss.
Access and permission management
Define granular roles (read, add, manage) per user. Modify or revoke access instantly.
File reception
Generate links allowing your clients or partners to send files directly to your secure space.
Email integration
Send secure files directly from your email client using our Gmail, Outlook and Thunderbird extensions.
Security
Security and confidentiality guaranteed
End-to-end encryption with hybrid post-quantum keys and zero-knowledge architecture. Your data is protected by cutting-edge cryptography that we cannot circumvent, even if asked.
Modern encryption
Protection against current and future threats. Your files are encrypted with hybrid post-quantum keys MLKEM768-X25519 (i.e. X-Wing).
Zero-knowledge architecture
We cannot access your files or their names. Only your authorized recipients have the decryption keys.
Local encryption on your device
Your files are encrypted directly in your browser before any transmission. Your sensitive data never travels in plain text.
Public white paper
Architecture, cryptographic model, and zero-knowledge guarantees are detailed in a freely accessible white paper.
No advertising tracking
No Google Analytics, no advertising cookies, no third-party scripts profiling you. Our usage statistics are aggregated and hosted on our own servers.
Sovereignty
Digital independence in the European Union
Infrastructure, company, and data 100% European. Sovereign hosting and independence from foreign jurisdictions. Your data remains under European law.
Exclusively European hosting
Your data is stored exclusively in the European Union, hosted by reference European operators certified HDS and ISO 27001 (Scaleway, Clever Cloud), replicated across three datacenters.
Privacy by design
Architecture designed to minimise access to personal data. Our zero-knowledge approach technically prevents us from accessing your files.
Independent French company
Based in Lyon, with no foreign shareholders or dependence on international groups. Complete decision-making sovereignty.
Zero American cloud in our stack
No AWS, no Azure, no GCP. Our hosting providers (Scaleway, Clever Cloud) are European operators independent from GAFAM. No direct exposure to the Cloud Act.
Zero AI
We don't use any AI in our product. No generative AI, no AI-assisted features, no AI at all. Just a secure, reliable platform that does what it promises.
Scalability without migration
Start free, scale up as your needs grow.

Frequently asked questions
Everything you need to know about security, privacy, and Retyc platform features.
Your files are encrypted locally on your device before sending, then decrypted only at your authorized recipients. We use modern cryptographic algorithms with post-quantum hybrid key support. In a zero-knowledge architecture, we never have access to your decrypted data or keys.
Zero-knowledge means we cannot access the content of your files, nor even their metadata (names, types). Only you and your authorized recipients have the decryption keys. This cryptographic guarantee protects you even if our servers are compromised.
Yes. Our post-quantum hybrid encryption integrates mechanisms resistant to known quantum computers. This anticipatory protection significantly reduces risks related to future decryption threats (harvest now, decrypt later).
A dataroom is a secure collaborative space for centralizing sensitive documents with fine-grained access management, automatic versioning, and complete traceability. Ideal for M&A transactions, due diligence, or confidential projects.
The Free plan allows simple file transfer. Solo and Business plans add collaborative datarooms with more storage and users. The Enterprise plan includes SSO, dedicated support, custom branding, and on-premises deployment. See our pricing page for details.
Your data is stored exclusively in the European Union, hosted by reference European operators certified HDS and ISO 27001 (Scaleway, Clever Cloud), replicated across three datacenters. Reduced exposure to American or Chinese extraterritorial legislation.
Our architecture is designed to minimise risks related to personal data processing. The zero-knowledge approach technically prevents us from accessing your encrypted files. We host exclusively within the EU. DPA (Data Processing Agreements) are available for Enterprise customers.
Yes. The Free plan lets you discover the platform without commitment or credit card. You can upgrade to Solo, Business, or Enterprise anytime based on your growing needs.
Yes. Our Enterprise plan includes SSO (SAML/OIDC), premium dedicated support, on-premises deployment, custom branding, custom domain, and custom integrations. Contact us for a demo.
No. Retyc has been available in stable release since June 2, 2026. The platform is used in production by professionals and organizations. All described features are fully operational.
