GDPR compliance & security

The 100% GDPR Compliant Electronic Signature

European infrastructure, end-to-end encryption, no data resale. HelloWeSign natively protects your data and your clients' data.

The ignored risk

Using an American service for your legal documents: truly GDPR compliant?

Many popular signature platforms are American and subject to the Cloud Act. Your confidential documents and your clients' data can legally be accessed by American authorities.

Hosting outside the EU

Most platforms store your data in the United States. The GDPR requires specific guarantees for transfers outside the EU, rarely met.

Data opacity

Where exactly are your documents? Who can access them? Are they used to train AI models? The answers are rarely clear.

Real legal risks

A data breach involving your clients can lead to regulatory sanctions, liability actions and lasting loss of trust.

The HelloWeSign approach

GDPR compliance by design, not as a patch

HelloWeSign was designed from the start with GDPR compliance as a fundamental requirement, not as an option added after the fact.

1

Data hosted in the European Union only

All your documents, signatures and personal data are stored on Railway Europe. No transfer outside the EU. No American server involved in processing your data.

Railway Europe — 100% EU infrastructure
2

SHA-256 encryption of all documents

Each uploaded document is hashed with SHA-256 to verify its integrity. File access is done via temporary pre-signed URLs, without direct exposure.

SHA-256 hashes + time-limited pre-signed URLs
3

Access controlled by secure tokens

Each signer has a unique single-use token. Access to the signing document expires. OTP codes are hashed and limited to 3 attempts.

Unique CUID tokens + hashed OTP + attempt limitation
4

Data deletion on request

In compliance with the GDPR, the right to erasure is respected. You can request the complete deletion of your data and your signers' data at any time.

Right to be forgotten — complete deletion on request
Security guarantees

All the protections you need

Every aspect of security has been designed to protect your sensitive data and your clients' data.

EU hosting (Railway Europe)

Infrastructure deployed in Europe. No data leaves European territory. Compliance with GDPR transfer requirements.

SHA-256 encryption

All documents are hashed. OTP codes and API keys are stored hashed, never in plain text. Timing-safe comparison to prevent attacks.

Temporary access tokens

Document URLs expire after 1 hour. Signing tokens are single-use. No uncontrolled permanent access.

No data resale

Your documents and data are never used for purposes other than the service. No sharing with third parties, no targeted advertising.

Right to be forgotten

Compliant with GDPR Article 17. Complete data deletion on request: documents, signatures, personal data.

eIDAS + GDPR compliance

Dual compliance: eIDAS for the legal validity of signatures, GDPR for the protection of personal data. Both, not one or the other.

Sensitive sectors

For professionals handling sensitive data

Some sectors simply cannot afford to take risks with data protection.

Law firms

Legal documents, deeds, agreements, confidential client information.

Professional secrecy and ethical obligations require the highest protection. HelloWeSign meets these requirements with EU hosting and secure access.

Medical sector

Patient consents, partnership agreements, practitioner contracts.

Health data is particularly sensitive under the GDPR. EU hosting and no data resale guarantee compliance.

Finance & Insurance

Financial contracts, mandates, general conditions, insurance quotes.

Financial data requires strict protection. The complete traceability and signature evidence from HelloWeSign meet regulatory requirements.
