বিক্রয়ের সাধারণ শর্তাবলি

Last updated: 11 November 2026

These terms of sale apply to all purchases made on ostone.app: subscriptions to paid plans and gift cards. They complete the terms of use. This text is a translation of the French version, which prevails if the two differ.

1. The seller

The seller is the publisher of Ostone, identified in the legal notice. Customer service: [email protected].

2. Offers and prices

• Ostone offers a Free plan, paid subscription plans (Pro, Studio, and Pro Student for art students) and gift cards.
• The content of each plan and the current prices are those shown on the Pricing, Students and Gift pages when you order.
• Prices include all taxes. VAT is calculated according to your country. If the price is shown in a currency other than the euro, the amount paid is the one shown on the payment page.
• We may change our prices. For a current subscription, any price change is announced to you by email at least 30 days before the renewal concerned. You can then cancel before that date.

3. Ordering

1. You create an account or sign in.
2. You choose a plan and its period (month or year), or a gift card.
3. You check the summary and pay on the secure page of our provider Stripe.
4. You receive a confirmation and a receipt by email. The contract is concluded at that moment.

Your invoices are available on your account page, under Invoices.

4. Free trial

When a free trial is offered, it lasts 7 days. A payment method is requested at the start of the trial. If you do not cancel before the end of the trial, the subscription starts and the first payment is taken. We remind you by email before the trial ends. The trial is limited to one per person and per computer.

5. Payment

You can pay by bank card, Apple Pay, Google Pay and, depending on the country, PayPal. Payment is processed by Stripe: we never see or keep your card data.

6. Duration, renewal and cancellation

• The subscription is taken out for one month or one year. It renews automatically for the same duration, at the current price, until you cancel it.
• You can cancel at any time, in a few clicks, from your account page, under Subscription. Cancellation takes effect at the end of the period already paid for: you keep your plan until then.
• For a yearly subscription, we remind you by email, between three months and one month before the renewal date, that you can choose not to renew.
• Apart from the right of withdrawal and the legal guarantees, a period that has started is not refunded.
• After cancellation, you return to the Free plan. Your projects stay on your computer: nothing is locked or erased.

7. Changing plan

You can move from Pro to Studio, or from monthly to yearly, from your account page. A higher plan applies immediately: you pay only the difference for the remaining period. A lower plan or a shorter period applies at the end of the period already paid for.

8. Failed payment

If a payment fails, we let you know by email and new attempts are made. Your plan is kept for 7 days to give you time to update your payment method. After that, you return to the Free plan, without losing your projects.

9. Right of withdrawal

• Subscriptions. You have 14 days from your first payment to change your mind, without giving a reason. We then refund that payment in full.
• Gift cards. You have 14 days from the purchase, as long as the code has not been redeemed. A card whose code has been redeemed can no longer be refunded.

To use this right, write to [email protected] from your account's address, or use the form on the Help page. You can use the model at the bottom of this page. The refund is made within 14 days of your request, to the payment method used for the purchase.

10. Student offer

• The Pro Student plan is reserved for students enrolled in an art school recognised by Ostone (music, film, design, theatre, dance and so on).
• Status is checked using the email address provided by the school. If the school is not yet on our list, the request is reviewed by hand.
• Status must be confirmed again once a year. Otherwise, the normal Pro price applies from the next renewal.
• A false declaration may lead to the student price being withdrawn.

11. Gift cards

• A gift card is a one-off payment, with no subscription and no renewal. It gives 1, 3 or 12 months of the Pro or Studio plan.
• The code is delivered right after payment: sent by email to the recipient or displayed for printing.
• The code is redeemed on the Redeem a code page, with an Ostone account. It works once and has no expiry date.
• If the recipient already has a subscription, the free months are added to their next renewal.
• A gift card cannot be exchanged for money or resold.
• If the code is lost, the buyer can contact customer service with their receipt.

12. Legal guarantees

If you are a consumer, you benefit from:

• the legal guarantee of conformity that applies to digital content and services (articles L. 224-25-12 and following of the French Consumer Code). Throughout your subscription, if the service does not conform to what was agreed, you can ask for it to be brought into conformity, free of charge. If that is impossible or takes too long, you can obtain a price reduction or end the contract and be refunded;
• the guarantee against hidden defects (articles 1641 and following of the French Civil Code).

To use these guarantees, write to [email protected].

13. Customer service and complaints

Write to [email protected] or use the form on the Help page. We usually answer within 48 working hours.

14. Consumer mediation

If your complaint has not been resolved by our customer service, you can use a consumer mediator free of charge. The contact details of the mediator Ostone belongs to will be given here before paid subscriptions open.

15. Governing law

These terms are governed by French law. If you are a consumer living in another country of the European Union, you keep the protection of the mandatory rules of your country. Failing an amicable solution, the dispute is brought before the court that has jurisdiction under the legal rules.
