Article 4. How Oyst works

The use of Oyst services allows the user to purchase and pay for goods or services online from Oyst’s partner merchant sites.


Payment service

Oyst uses the services of an authorised payment service provider, used by many e-commerce sites, which ensures data security and protection in accordance with regulations.

The payment service provider:

  • hosts and provides the payment service;
  • holds a licence as a payment institution and is authorised to operate in France.


When the user places a first order and pays for the payment by credit card on the payment service, the bank details are automatically encrypted on the user’s computer before being sent encrypted by Oyst to the payment service provider.

By using the Oyst services, the user accepts that his credit cards are registered by Oyst in an encrypted and secure manner, it being specified that Oyst does not have access to the users’ credit card data.

In order to guarantee data security, Oyst takes all necessary precautions, whether physical, logical, administrative or organisational, with regard to the nature of the data it processes and the risks presented by the various processing operations, to preserve the security of the data and to prevent them from being distorted, damaged or accessed by unauthorised third parties. These measures include automatic encryption of bank data.


During the user’s subsequent purchases, Oyst technology makes it possible to recognize the user and avoid having to re-enter his personal data (delivery address, e-mail address, telephone number, etc.) as well as his bank details.

In addition, using cookie technology, Oyst will also offer the user its services for the purchase of products and services on the websites of partner merchants. By clicking on Oyst’s 1-Click button the user will be able to purchase these products and services without having to re-enter their personal and bank details.

Oyst strives to offer the user the best availability of Oyst services.

Conditions of access

The use of Oyst services is only available to individuals over 18 years of age, and to legal entities that can legally form legally binding contracts.

Oyst services are not accessible to persons whose access to services has been suspended.

Acceptance of payment

The user, identified and authenticated, expresses his express consent to validate online the completion of the purchase:

  • by clicking
  • possibly by entering his phone number to secure the payment
  • and by choosing not to cancel his order

Proof of purchase

This acceptance constitutes proof of its consent to these purchases and proof that they are charged to the bank account associated with the bank card by the payment service provider.

Proof of purchase can be provided by any means, including computerized registrations by Oyst, the payment service provider or partner merchant sites.

Oyst can use these records as justification for charging them to the payment card registered on Oyst.

These recordings justify the consequences that result from them.  They shall be evidence of the identity of the user concerned, the dates and associated times, the commitment of the user, through the instructions given, the form and content relating to the operation concerned.

User space

When first using the Oyst service, the user receives an account creation confirmation email from Oyst containing a link to a URL allowing him to access his user space.

Within his space, the user has access to a summary of all the purchases he has made via the Oyst service with the contact details of the partner merchant sites with which he has contracted.

The user also has access to his or her contact details in order to modify and update them.

The user can also choose to delete his personal information or his space.

Obligation of means

Oyst is expressly subject to a best-efforts obligation under these terms and conditions when making the Oyst solution available to the user.

 Article 6. Rôle d’Oyst

Oyst: Oyst is a service provider that allows its partner merchants to sell their products and services to users with a single click.

Oyst is neither the buyer nor the seller of its partner merchants’ products Oyst provides a transaction optimizer, its partner merchants as sellers initiate and finalize transactions.

Oyst is in no way a reseller of the products of its partner merchants and does not come into possession of these products at any time. Nor does Oyst act as an agent or representative of its partner merchants.

There is only a validly formed sales contract between the user as buyer and the partner merchant as seller. The terms of this contract are described in the partner merchant’s general terms and conditions of sale, which are displayed and accepted by the user at the time of payment or have been previously accepted by the user.

In this respect, the user acknowledges and accepts that only the partner merchant’s general terms and conditions of sale are enforceable against him/her in the context of his/her relationship with the partner merchant. The use of the OYST Solution on the partner merchant’s website by the user constitutes acceptance by the user of the partner merchant’s general terms and conditions of sale, as applicable on the day of the transaction.

Therefore, sales made between a partner merchant site and the user are transactions between the user and the partner merchant site and under no circumstances with Oyst, which assumes no liability of any kind whatsoever in this context.

The merchant partner is responsible for any claim or problem related to the sales contract binding it to the user.

In addition to the contractual rights of its user and in order to make its user’s shopping experience more secure, Oyst offers an A to Z guarantee as a last resort to its user regarding purchases made by its user from its partner merchants via the 1-Click button managed by Oyst.

In the event of a complaint or any other problem related to a sales contract formed via the 1-Click button of Oyst, between the user and one of our partner merchants, the user must first contact the seller’s customer service. To this end, we provide our user with the customer service details of all our partner merchants with whom they have contracted via the Oyst 1-Click button via their user area.

As a last resort, Oyst provides the user with a customer service to process his request. He can be reached by phone from Monday to Friday from 9am to 7pm at +33 1 79 73 73 83 73 (call not surcharged), or by email at the following address:

Oyst will then endeavour to allow, if necessary, contact between the user and the customer service of the partner merchant site, as well as the processing of the user’s request by the partner merchant site. In the event of failure to perform the latter, Oyst will apply to the user the guarantees and conditions inherent in the general terms and conditions of sale accepted by the user at the time of purchase.

The same shall apply to any request for refunds, returns, exercise of the right of renunciation or any other right arising from a stipulation of the general terms and conditions of sale or a legal obligation arising from the sales contract between the user and a merchant partner.

This guarantee can only be used as a last resort, once the user has legitimately justified to Oyst that his attempts to settle his request directly with the seller have not been successful and that he has exhausted all legal remedies in his possession to do so.
