Frequently asked questions about electronic signature
Everything you need to know before signing your first document online.
Does electronic signature have the same legal value as a handwritten signature?
Yes. The eIDAS European regulation (No. 910/2014) recognizes electronic signature as legally enforceable in all European Union member states, in the same way as a handwritten signature. Certyneo offers the three levels provided for by the regulation (simple, advanced and qualified), with cryptographic proof timestamped attached to each signed document.
What is the difference between simple, advanced and qualified signature?
Simple electronic signature (SES) authenticates a signer by email and is sufficient for most commercial contracts. Advanced signature (AES) adds an OTP via SMS and a certificate linked to the signer, recommended for HR, credit and sensitive contracts. Qualified signature (QES) requires face-to-face or video identity verification and offers the highest evidentiary value provided for by eIDAS.
What is the eIDAS regulation?
eIDAS (electronic IDentification, Authentication and trust Services) is European regulation No. 910/2014 which has governed electronic identity and trust services in the European Union since 2016. It defines the legal value of electronic signature, technical requirements for trust service providers and guarantee levels applicable to signatures.
How long are my documents archived?
All documents signed on Certyneo are stored for 10 years in an encrypted digital safe, included in all plans at no extra cost. Archiving complies with the requirements of Article 1379 of the French Civil Code and remains accessible at any time via your client portal or via REST API.
Is Certyneo GDPR compliant?
Yes. Certyneo is entirely hosted in the European Union (Germany), no customer data leaves European territory. We offer a signable DPA (Data Processing Agreement) on request, an up-to-date subprocessor register, and export and deletion tools compliant with your signatories' GDPR rights.
How to migrate from DocuSign or Yousign?
Our migration team supports you free of charge: recovery of your existing templates, import of your address book, user training and recovery of signature history when technically possible. The switch typically takes between 48 hours and 5 business days depending on volume.
What file formats are supported?
PDF natively (recommended format), as well as Word (.docx), Excel (.xlsx), PowerPoint (.pptx), images (PNG, JPG) and OpenDocument. All non-PDF formats are automatically converted to PDF/A before signature to ensure long-term archiving compliant with ISO 19005 standard.
Can you sign from a smartphone?
Yes. The signature interface is fully responsive and works on any recent mobile browser (iOS Safari, Android Chrome, Firefox), with no application to install for the signer. Administrators can manage their envelopes from our iOS and Android applications available on the App Store and Google Play.
Is there an API to integrate Certyneo?
Yes. A complete REST API allows you to create envelopes, manage templates, track statuses in real time and receive HMAC-signed webhooks for each event (send, open, sign, refuse). Public OpenAPI documentation, official SDKs, free test environment and transparent rate limits.
What is the right price for an SME?
Our Standard plan at €19/month covers 100 envelopes and 10 users with eIDAS advanced signature, sufficient for most SMEs. For teams exceeding this volume, the Business plan at €39/month adds bulk sending, web forms for mobile and payment collection during signature.
