The information provided by Participants may be used by the Organising Company.

2.1. Principle

The Competition is open to any natural person of legal age, who holds an email address or Instagram account, with the exception of permanent or occasional staff members of the Organising Company, its suppliers, and anyone who has had professional contact with the Organising Company for this operation (hereinafter "the Participant(s)").

To take part in the Competition, Participants must visit the website www-yse-paris.com and the page dedicated to the Competition.

On the site: between 23rd and 30th April 2026, they must enter their details. By submitting the form, Participants will be registered for Ysé’s Newsletter. Participants may only complete the dedicated page on the site once, during the Competition period.

2.2. Participation and Validity Conditions

Registering under a false identity or providing false information, or registering under several identities, will result in cancellation of participation. Furthermore, entries will be void if they are incomplete, incorrect, fraudulent, or are otherwise in breach of these rules.

The winner will be drawn at random on 4th May 2026.

The winner will be notified by email within five days. They must confirm receipt of their prize by replying to the email or message within the following week. If there is no response, they may be contacted by phone.

If the winner cannot finally be contacted and does not reply within this time frame, they will forfeit the prize and a new Participant may be drawn.

One person will win: 

• a Ysé gift card worth €300 to spend on the website www.yse-paris.com or in the Ysé store in Brussels. Any unused balance will be lost.

Only one winner will be drawn at random from among the Participants.

In the event of force majeure or if circumstances require, the Organising Company reserves the right to replace the awarded prizes with others of an equivalent nature and value.

The winner is not entitled to receive the cash equivalent of the prizes or to request their exchange for other goods or services, even if they decide to refuse or withdraw from the Competition.

In such a case, prizes will be forfeited.

The Organising Company will inform the winner by email within five days of the draw on 4th May 2026.

The Organising Company cannot be held responsible if, for reasons beyond its control, notification to the winner is lost or does not reach its destination due to a malfunction or a change in contact details.

If the winner does not acknowledge receipt of their prize notification or does not communicate their choice of dates for the stay within the required time frame, they may be contacted by phone. If they cannot be contacted by any means, they will forfeit their prize.

Participation in this Competition implies, for the benefit of the Organising Company and the Competition Partners, authorisation to publish the winner’s name on all current and future media and communication channels, and at any advertising/promotional event relating to the Competition, without such use giving rise to the payment of any compensation, other than the prizes specified.

The names and contact details of Participants may be subject to computer processing by the Organising Company.

In accordance with Regulation (EU) 2016/679 of 27 April 2016 on the protection of personal data, Participants have the right at any time to access, rectify, or delete their personal information, as well as the right to object to the processing of such data.

To do so, Participants simply need to make a request, providing their contact details and a copy of their ID, by email to bonjour@yse-paris.com.

For more information about the processing of their personal data, Participants are invited to refer to the Privacy Policy available on the website www.yse-paris.com.

The Organising Company cannot be held responsible if a person:

- suffers a technical breakdown of any kind (line status, power failure, server incident, accidental disconnection, etc.),

- provides incorrect or incomplete contact details which do not allow for them to be notified of their win.

Participating in the Competition implies awareness and acceptance of the features and limitations of the technologies used by the Internet and those related to it, particularly regarding technical performance, response times for viewing, querying or transferring information, risks of interruption, and more generally, the inherent risks of any connection and transmission, the lack of protection of certain data against possible misappropriation, and the risk of contamination by any viruses circulating on the network.

Consequently, the Organising Company cannot, under any circumstances, be held liable—without this list being exhaustive—for:

- the content of services viewed on the Internet and, more generally, any information and/or data disseminated on services viewed on these sites;

- the transmission and/or reception of any data and/or information over the Internet;

- any malfunction of the Internet network that prevents the proper conduct/operation of the Competition;

- failure of any reception equipment or communication lines;

- loss of any paper or electronic mail and, more broadly, loss of any data;

- distribution issues;

- the operation of any software;

- the consequences of any virus, computer bug, anomaly, technical fault;

- any damage caused to a Participant’s computer or mobile phone;

- any technical, hardware, or software failure of any kind that prevented or limited the ability to participate in the Competition or damaged a Participant's system.

It is specified that the Organising Company cannot be held liable for any direct or indirect damage resulting from an interruption, malfunction of any kind, suspension or ending of the Competition, for any reason whatsoever, or for any direct or indirect damage that may result, in any manner, from connecting to the Internet.

It is the responsibility of every Participant to take all appropriate measures to protect their own data and/or software stored on their computer equipment against any infringement.

Internet connection and participation in the Competition are the sole responsibility of the participant.

The Organising Company cannot be held responsible if, for reasons beyond its control, the Competition is partially or totally amended, postponed or cancelled. No compensation may be claimed in this respect.

In any event, if the proper administrative and technical conduct of the Competition is disrupted by a virus, computer bug, unauthorised human intervention, or any other cause outside the Organising Company’s control, it reserves the right to interrupt it.

The rules of this Competition can be sent free of charge to anyone who requests them from L’Impertinente at the following address: 71-73 rue de Provence, 75009 PARIS. They will also be available to view on the Competition’s dedicated page on the website www.yse-paris.com.

The Organising Company may rely, especially as evidence, on any act, fact, or omission, programmes, data, files, records, operations or other elements (such as monitoring reports or other statements) established, received or retained directly or indirectly by the Organising Company, notably in its information systems, relating to the Competition.

Participants undertake not to contest the admissibility, validity or evidential value of the aforementioned elements, on the basis of any legal provision stating that certain documents must be written or signed by the parties to constitute evidence.

Thus, such elements shall be considered as useful, admissible, valid and enforceable evidence between the parties in the same manner, under the same conditions and with the same evidential value as any document created, received or stored in writing.

Participation in the Competition implies full and unconditional acceptance of these rules and terms.

The Organising Company reserves the right to cancel, amend, shorten or extend this operation, in whole or in part, if circumstances so require, without having to justify the decision and without being liable for compensation.

It is expressly agreed that the applicable law is French law. Any dispute will fall under the jurisdiction of the Paris courts. However, for Participants residing abroad, local regulations may apply if they are more favourable to them.
