Terms and Conditions

1. Scope of service

sigillo provides a hosted service for sealing PDF documents via its Swiss signature partner SwissTrustLayer — as a timestamp and as a qualified electronic signature (on-demand and multi-signer). Access is via web interface, REST API and MCP interface.

2. Credits and billing

Usage is billed from a balance of credit packs purchased one-off, without subscription. Credits do not expire. The cost per operation is shown before execution (timestamp 1 credit, QES on-demand 5, multi-signer 5 per signer). If an operation fails on the signature service side, the credits are refunded automatically.

3. Customer obligations

The customer ensures they are authorised to seal the submitted documents and that no third-party rights are infringed. API tokens must be kept confidential.

4. No legal advice

sigillo provides solely the technical sealing and is not a substitute for legal advice. Whether a timestamp or a QES is legally sufficient for a specific use case must be assessed by the customer or their legal counsel.

5. Availability

We strive for high availability but do not owe uninterrupted availability. The QES and timestamp functions additionally depend on the upstream service of SwissTrustLayer.

6. Liability

Liability is governed by statutory provisions. For slight negligence we are liable only for breach of material contractual obligations and limited to the foreseeable damage typical for this type of contract.

7. Data protection

Our privacy policy applies.

8. Final provisions

Austrian law applies, place of jurisdiction is Salzburg (Austria), to the extent legally permissible. Should any provision be invalid, the validity of the remaining provisions is unaffected.
