Terms of sale and use
Effective from November 1, 2026. This is a translation of the French terms (CGV), which prevail in case of difference.
1. Purpose
These terms (the "Terms") govern the use of the Grind online service (the "Service") and the Grind Pro subscription. The Service is published by Mamadou Camara, sole trader (entrepreneur individuel) registered in France, SIRET 132 040 353 00014, reachable at grind.contact9@gmail.com (the "Publisher"). Using the Service means accepting the Terms.
2. The Service
Grind helps students organize their studying: a schedule worked out from the subjects, topics and exam dates they enter, a focus timer and progress tracking. The data stays in the user's browser; the Publisher has no access to it. Grind is an organization tool and does not guarantee any exam result.
3. Users under 18
The free version can be used freely. The Pro subscription is taken out by an adult, or by a minor with the agreement of their parent or legal guardian, who is then bound by these Terms.
4. Plans and prices
- Free plan: 1 subject, automatic schedule, timer, streaks and XP, story image.
- Pro plan: $9.99 per month. Unlimited subjects and detailed stats.
Prices in US dollars, charged by Stripe; your bank may add currency conversion fees. VAT not applicable (French VAT exemption, art. 293 B of the French Tax Code). Any price change to an ongoing subscription is notified by email at least 30 days before it applies; the subscriber can cancel before that date.
5. Subscription and payment
You subscribe through the secure Stripe payment page, by card. The subscription then renews automatically every month. An invoice is emailed after each payment. Pro access is activated on the device and browser used when subscribing; for another device, contact the Publisher.
6. Duration and cancellation
Monthly subscription, no commitment, renewing automatically. Cancel anytime, in a few clicks, from the subscription management page: https://billing.stripe.com/p/login/8x25kD4cH1ObbraaZ0gYU00, or by email. Cancellation takes effect at the end of the current period.
7. Right of withdrawal
Consumers have 14 days from subscribing to withdraw without giving a reason (article L221-18 of the French Consumer Code), by simple email to grind.contact9@gmail.com. The refund is made within 14 days.
8. Liability
The Publisher has an obligation of means. It cannot be held liable for exam results, errors in the data entered, the loss of data stored in the browser, or interruptions due to maintenance, the host or force majeure.
9. Intellectual property
The Service, its code, its design and its brand remain the property of the Publisher. Content entered by users belongs to them.
10. Personal data
See the legal notice.
11. Complaints and disputes
Contact the Publisher first at grind.contact9@gmail.com. The Terms are governed by French law, without depriving consumers of the protection of the mandatory rules of their country of residence.
