Terms of sale — Solvissima+

This page is an English translation provided for convenience; the French version of this page is the legally binding one.

Article 1 — Purpose

These terms govern the paid "Solvissima+" subscription offered on solvissima.com. The game, challenges, leaderboard, quests, trophies and learning pages remain accessible for free and without a subscription; Solvissima+ does not gate access to them.

Article 2 — Publisher

Solvissima is published by NES STUDIO, a SASU with share capital of €5,000, registered with the Paris trade register (RCS Paris) under number 107 701 393, with registered office at 47 rue Vivienne, 75002 Paris, represented by Nicolas Sansonetti. Contact: infos@solvissima.com. Intra-community VAT number: FR04107701393.

Article 3 — Content of the offer

Solvissima+ includes, for the entire duration of the subscription: removal of advertising inserts across the whole site; detailed statistics; your complete game history (without a subscription, only the last 30 days are displayed; nothing is deleted); printable puzzles: archives of previous months and fresh sets on demand (without a subscription, one PDF per level and per month); immediate access to all special grids; the S+ badge on the leaderboard. The content may evolve; a substantial reduction is notified by email at least 30 days in advance, with the option to cancel at no cost.

Article 4 — Price

Two plans: monthly at €2.99 incl. tax per month, annual at €24.99 incl. tax per year. A launch offer "First players" (code PREMIERS) grants the first 250 annual subscribers a 20% discount maintained on every renewal as long as the subscription remains active without interruption; cancelling and then re-subscribing applies the price then in effect. Prices in euros, French VAT included at the applicable rate. Any price change is notified by email at least 30 days before it applies and only applies to the following period; you can cancel before that date at no cost.

Article 5 — Order

The subscription requires a Solvissima account (verified email address). The order is placed from the Solvissima+ page: choosing the plan, accepting these terms and the waiver of the right of withdrawal (article 9), then payment. A confirmation email summarises the plan, the price, the start date and the renewal date.

Article 6 — Payment

Payment is handled by Stripe Payments Europe Ltd; NES STUDIO never holds any card data. Payment is taken at the time of order and on each renewal. If a payment fails, Stripe retries for 7 days; Solvissima+ access is maintained during this period, then suspended until payment is regularised. Invoices are available in the subscription management area.

Article 7 — Term and renewal

The subscription starts when payment is confirmed, for one month or one year depending on the plan, and automatically renews for periods of the same length. For the annual subscription, a reminder email is sent between 3 months and 1 month before the renewal date (article L. 215-1 of the French Consumer Code).

Article 8 — Cancellation

You can cancel at any time from your account ("Manage my subscription"), without justification. Cancellation takes effect at the end of the current period; Solvissima+ access is kept until that date and no further payment is taken. NES STUDIO may cancel in case of fraud, proven leaderboard cheating or abusive use, after email notice.

Article 9 — Right of withdrawal

Solvissima+ is digital content supplied immediately. In accordance with article L. 221-28 13° of the French Consumer Code, by ticking the box provided when ordering you request immediate performance and expressly waive your 14-day right of withdrawal. As a commercial gesture, an annual subscription can be refunded in full on simple request to infos@solvissima.com within 14 days of the first payment, excluding renewals.

Article 10 — Personal data

The data processed for the subscription is: email address, Stripe customer id, plan, start and end dates, status. Legal basis: performance of the contract. Retention: lifetime of the account, then 10 years for accounting records. Recipients: Stripe (payment) and Brevo (service emails). No card data is ever known to NES STUDIO. Your rights and the rest of our practice are described on the Your data page; deleting your account cancels the subscription at the end of the paid period.

Article 11 — Availability and liability

NES STUDIO commits to a best-efforts obligation regarding service availability. In the event of an interruption longer than 72 consecutive hours attributable to NES STUDIO, the subscription period is extended accordingly. NES STUDIO is not liable for interruptions caused by your device, your connection or a third party. The puzzles, techniques and texts of the site are the property of NES STUDIO; the subscription does not transfer any rights, and downloaded PDFs are for personal use only.

Article 12 — Complaints, mediation, applicable law

Any complaint should first be sent to infos@solvissima.com; a reply is given within 15 days. If no solution is found, you can refer the matter free of charge to the consumer mediator NES STUDIO falls under (appointment in progress: contact details will be published here once confirmed, and provided on request at infos@solvissima.com), or to the European online dispute resolution platform. These terms are governed by French law. Version of 2 November 2026.
