Privacy & data protection

SignCloud covers electronic signature, identity verification and e-mail evidence services. This notice explains what data is processed when you use the services, and for what purposes.

Controller

For your customer-account data, the controller is MILONO HOLDING, operating the services under the SignCloud brand, 254 Rue Vendôme, 69003 Lyon, France. Contact: contact@signcloud.fr. For the documents you send for signature, the persons you have verified and the e-mails you have sealed, you (or the issuing organisation) are the controller, SignCloud acting as processor (see the DPA).

Data processed

  • Documents. The PDF files you upload for signature are kept for as long as needed for signing and evidence retention.
  • Signers. Name and contact details (email and/or phone) provided to send the document and the verification code.
  • Signature evidence. Timestamp, IP address at signing time, channel and recipient of the verification code, SHA-256 fingerprint of the sealed document.
  • Identity verification (SignCloud Identity). Images and data of the ID document (NFC chip where available) and liveness captures compared to it, based on the verified person's express consent. Sensitive captures are used solely for the verification; abandoned or unnecessary sensitive data is purged automatically (within 24 h at the latest), only the timestamped verification certificate being kept.
  • E-mail evidence (SignCloud Mail). Message content and attachments (encrypted at rest, AES-256), sender/recipient addresses, SMTP delivery transcripts, opening/acknowledgement events. Originals can be purged at any time; certificates and fingerprints remain verifiable.
  • Demo (48 h). Details provided for a demo are used only for it; the demo account and all its data are deleted automatically at expiry (deletion logged).

Purposes & legal basis

This data is processed to perform the requested signature service (contractual basis) and to maintain the technical record associated with the transaction (legitimate interest, where applicable).

Retention

For each finalised document, the customer selects a 10, 20 or 50-year retention policy according to its purpose and legal basis. A separate integrity-controlled package is deposited in external storage. This service is not represented as a certified electronic archiving system, and expiry handling remains subject to contractual, statutory and legal-hold requirements. No data is sold to third parties for commercial purposes.

Hosting & subprocessors

Primary hosting in France (o2switch) with encrypted off-site backups: Hetzner, Germany (European Union). We rely on subprocessors for specific functions, which only access the data needed for their task:

  • o2switch (France) — service hosting.
  • Stripe — online payments and identity verification (KYC).
  • OpenAI — AI-assisted contract drafting (only when you use it).
  • Encrypted off-site backups: Hetzner, Germany (European Union).
  • RFC 3161 timestamp authority — only the document fingerprint (hash) is transmitted: never content or personal data.
  • Self-hosted SMS gateway and email gateway — verification codes and notifications.

Legal framework

The service records technical evidence designed for electronic-signature workflows and implements personal-data protection measures. The legal qualification of each signature level and the privacy documentation must be reviewed against the production configuration and the customer's use case.

Your rights

You have the right to access, rectify and erase your data. To exercise it, contact the organization that sent you the document via SignCloud.

For a SignCloud customer account, the deletion process is available on the dedicated account deletion page.
