Terms & Conditions

These Terms govern your purchase and use of Solvarv and any other software or digital product ("Products") sold by 10yx OÜ ("we," "us," "the Company"), a private limited company registered in Estonia. By buying or using a Product, you agree to these Terms.

Where you are buying as a consumer, mandatory consumer protection law in your country of residence applies in addition to these Terms. Nothing here removes or limits rights you have under that law.

1. The contract

Your order is an offer to buy a Product. The contract is formed when we confirm your payment and make the Product available to you. 10yx OÜ is the seller of record.

2. Licence

2.1 What you get

On payment, we grant you a perpetual, worldwide, non-exclusive, non-transferable licence to install and use the Product for your own purposes — personal or professional — on devices that you own or control. Solvarv is sold as a one-time purchase: that licence does not expire and does not require an ongoing subscription.

2.2 What you may not do

You may not redistribute, resell, sublicense, rent, or publish the Product or any part of it; remove or circumvent licensing or protection measures; or use the Product or its outputs to train machine-learning models. You may not reverse-engineer the Product except to the extent that applicable law expressly permits it regardless of contract.

2.3 Updates

Updates we choose to release for a Product you have bought are provided on the same licence. We do not commit to a specific update schedule unless the Product page says otherwise.

3. Price, tax, and payment

Prices are shown on the Product page in euro. 10yx OÜ is not currently registered for VAT, so no VAT is added at checkout — the price you see is the total you pay. If our VAT status changes, prices and this section will be updated before the change takes effect. Payment is processed by Stripe; we do not receive or store your full card details.

4. Delivery

Solvarv is delivered electronically, normally immediately after payment, by download link or download access sent to the email address you provide at checkout. It is your responsibility to give a working email address. If you have not received your Product, email [email protected] and we will resolve it.

5. Right of withdrawal and refunds

5.1 Statutory right of withdrawal

If you are a consumer in the European Union or the United Kingdom, you normally have 14 days from the conclusion of the contract to withdraw without giving a reason.

5.2 We do not currently disapply that right

The law allows a trader to end the withdrawal right for digital content delivered immediately, but only where the customer expressly consents to immediate delivery, acknowledges losing the right, and receives confirmation of both on a durable medium. Our checkout does not ask for that consent, so we do not rely on this exception — your 14-day right applies in full. In practice our refund policy below is more generous than the statutory minimum.

5.3 Our own refund policy

Beyond the statutory position, we will refund any Product within 30 days of purchase if it does not work for you — no explanation required. Email [email protected] with your order details. Refunds are issued to the original payment method. We may withdraw your download access once a refund is made.

5.4 Faulty products

If a Product is faulty or not as described, you are entitled to a repair, replacement, price reduction, or refund under applicable consumer law. These rights are not affected by section 5.3.

6. What we promise about the Product

We will supply the Product as described on its Product page at the time of your purchase, and we take the accuracy of those descriptions seriously. Where system requirements are stated, the Product is warranted to run on systems meeting them.

Beyond that, and to the extent permitted by law, Products are provided as they are. We do not warrant that a Product will be free from all defects or uninterrupted in operation. Nothing in this section limits the statutory conformity rights of consumers.

7. Acceptable use

You may not use our Products, websites, or services to break the law; to infringe others' rights; to attack, overload, or gain unauthorised access to our systems; or in breach of applicable sanctions. We may block, rate-limit, or refuse service to protect our infrastructure.

8. Intellectual property

All intellectual property rights in the Products — software, designs, text, images, trademarks — remain with the Company. Your purchase grants the licence in section 2 and nothing more. Use of our trademarks requires our written permission. Content you create using a Product belongs to you; we claim no rights in it — and in Solvarv's case it never leaves your device.

9. Liability

We do not exclude or limit our liability for death or personal injury caused by negligence, for fraud, or for anything else that may not lawfully be limited — including a consumer's statutory rights.

Subject to that, our total liability arising out of or in connection with a Product is limited to the amount you paid for it. We are not liable for indirect or consequential loss, or for loss of data, profit, or business, except where such loss results from our failure to supply a Product that conforms to its description.

We recommend you keep your own backups of any data you create with our Products. Solvarv stores your data on your device only, and we have no copy of it.

10. Suspension and termination

We may suspend or terminate access to our services if you materially breach these Terms — in particular sections 2.2 or 7. Where you are a consumer and the breach is capable of remedy, we will give you notice and a reasonable opportunity to remedy it first. Termination does not affect a perpetual licence you have already paid for, unless the breach concerns unlawful distribution of the Product itself.

11. Changes to these Terms

We may update these Terms for future purchases. The Terms that apply to your purchase are those in force at the time you bought, and we will not change them retroactively to your disadvantage. The "last updated" date above reflects the current version.

12. Governing law and disputes

These Terms are governed by Estonian law. If you are a consumer resident in the EU, this does not deprive you of the protection of the mandatory law of your country of residence, and you may bring proceedings in your local courts.

If you have a complaint, contact us first at [email protected] — we would rather resolve it directly. If we cannot, consumers in the EU may contact the consumer protection authority or an alternative dispute resolution body in their country of residence. For cross-border purchases within the EU, the European Consumer Centres Network (ECC-Net) can assist.
