Terms and Conditions

1. Purpose

These terms govern access to the Sigalion services and the sales associated with them. They apply to the Sigalion Vault application on macOS, Windows, Linux, iOS and Android, to the sigalion.fr website, to the client area at client.sigalion.fr and to the API at api.sigalion.fr.

They are published by Sigalion, a simplified joint-stock company registered with the Pau Trade and Companies Register under number 942 406 463. Its full contact details appear in the legal notice, which is their only source.

2. The services

2.1. Sigalion Vault, free mode

Sigalion Vault can decrypt a password-protected file without an account and without a purchase. The processing takes place on your device.

2.2. Sigalion Vault, full mode

Full mode gives access to encryption, electronic signature, timestamping and encrypted file transfer. It requires a licence and an account.

The licence is personal, non-transferable, valid without time limit, and covers every supported operating system.

2.3. Sending a password by SMS

The application can send the password of an encrypted file by SMS to a recipient of your choosing. This function is optional and consumes SMS credits. The number you enter is not checked on our side, and an SMS that has been sent can no longer be cancelled.

How the message is handled is described in the privacy policy.

2.4. Timestamping

The timestamping service issues tokens compliant with the RFC 3161 standard. Two levels exist side by side.

The first is free, available without an account, and issued by Sigalion's own timestamping authority. This token is not a qualified electronic time stamp within the meaning of the eIDAS Regulation: it attests to a date by means of an authority that is not a qualified trust service provider.

The second is qualified. The token is then issued by a qualified trust service provider within the meaning of the eIDAS Regulation, to which Sigalion forwards your request. Sigalion is not a qualified trust service provider and never presents itself as one. This level consumes timestamping credits.

Verifying a token or a signed file requires no account and no purchase.

2.5. Application programming interface

An application programming interface makes it possible to obtain tokens from third-party software. It requires an access key created from the client area. The key is personal and you are answerable for its use. Each qualified token obtained consumes one credit. A key may be suspended in the event of manifestly abusive use.

3. Account

An account requires a valid licence, an email address and a password. You provide accurate information, you keep your credentials confidential and you inform us of any unauthorised use of your account.

4. Purchases

4.1. Products

The following are offered for sale: the Sigalion Vault licence, SMS credits, qualified timestamping credits and the Giga plans, which open temporary storage for encrypted files. Details and prices appear on the purchase pages.

Prices may change. A change applies only to subsequent orders.

4.2. Prices and taxes

Prices are shown excluding tax. The applicable tax is calculated and shown before payment, according to your country and your status. Businesses established in the European Union and holding a valid intra-Community VAT number fall under the reverse charge procedure.

An invoice is issued on request, from the billing information you enter in your client area. It remains available there.

4.3. Ordering and payment

The licence is purchased on sigalion.fr or from the iOS and Android applications. Credits and Giga plans are purchased from the client area or from those same applications. Payment made on the website is handled by a payment provider, Sigalion never having knowledge of your banking details; purchases made within the applications are covered by article 4.4. The order is confirmed by email.

4.4. Purchases within the mobile applications

The iOS and Android applications give access to the same service. Purchases made there are concluded with Apple or with Google, who bill and refund them under their own terms. The service, the account and the data remain governed by these terms.

4.5. Delivery

The licence is delivered by email as soon as payment is validated, together with the application download links. Those links remain available from the website and from your client area. Credits and Giga plans are added to the account as soon as payment is validated.

4.6. Right of withdrawal

The products sold are digital content supplied without a tangible medium and performed immediately.

By confirming your order, you request that immediate performance and you acknowledge that you expressly waive your right of withdrawal, pursuant to article L221-28 of the French Consumer Code. For a licence purchased on the website, this waiver is collected by means of a tick box and restated in the confirmation email.

4.7. Statutory guarantee

The digital content and digital services supplied benefit from the statutory guarantee of conformity provided for in articles L224-25-12 and following of the French Consumer Code. Non-conforming content may be brought into conformity free of charge, or give rise to a price reduction or to termination of the contract under the conditions laid down by law.

5. Credits and plans

Credits are added to the account and drawn down as they are used. SMS and timestamping credits are granted when the account is created.

Credits do not expire for as long as the account exists. Storage plans are limited in time according to the Giga plan chosen.

Credits are neither taken back nor exchanged for a refund, without prejudice to the statutory guarantee referred to in article 4.7.

6. Availability and liability

We use reasonable means to keep the service available. We do not guarantee that it will run without interruption, in particular where it depends on third parties, such as the delivery of SMS messages or the issuance of a qualified token. Free services may be limited, modified or discontinued at any time.

Our liability is engaged under the conditions of the general law. It does not cover indirect damage. Nothing in these terms excludes liability that the law does not permit to be excluded.

7. Use of the application

The licence allows you to install and use the application on devices you own or control, for personal or professional purposes.

You may not resell it, rent it out, sub-license it, nor decompile it or reverse-engineer it beyond what the law allows.

You are responsible for the files you encrypt, sign, timestamp or transmit, and for their compliance with the law.

8. End of the contract

You may close your account at any time from your client area. Closure is final: the account, the licence, the credits and the stored files are deleted, and it does not give rise to any refund of purchases already performed.

We may suspend or close an account in the event of use contrary to these terms or to the law. Save in an emergency or where the law requires otherwise, we inform you beforehand and allow you time to put matters right.

9. Changes to these terms

These terms may be amended. The version applicable to an order is the one in force on the day of the order.

10. Complaints and disputes

For any complaint, write to us quoting your order reference. We reply as promptly as we can.

In the event of a dispute, an amicable solution will be sought before any legal action.

11. Governing law

These terms are governed by French law.

This document is written in French; in the event of any discrepancy with a translation, the French version prevails.

12. Contact

Through the contact form on the website, by email at the address given in the legal notice, or by post to the registered office.
