Terms and conditions

Updated on 1 October 2026.

1. Who we are and who these terms apply to

Prevvia makes 3D simulators for companies that sell and install home products, such as solar energy and swimming pools. Prevvia is operated by Eloquentmirror - Unipessoal Limitada, VAT 518615901, Rua Luís de Camões, 2640-501 Mafra, Portugal. These terms apply to the purchase and use of the simulators, the client area and Prevvia’s other services.

The service is for businesses and professionals, who buy it as part of their business activity. It is not intended for consumers.

2. The service

Each simulator is a 3D experience in your company’s branding, added to your website with two lines of code or used as a direct link (for example, in ads). Visitors answer questions, see an estimate and can leave their details; your company receives the lead by email and in the client area.

Each simulator you subscribe to includes unlimited quote requests and visits, customisation of the branding, questions, prices and 3D scene, email alerts and access to the client area.

3. Prices and payment

Each simulator costs €19.99 a month or €199.90 a year, excluding VAT. VAT is added according to your company’s country and VAT number.

With the pergola simulator, the bespoke setup (your company’s prices, models and colors in the simulator) is optional and costs €99.00, excluding VAT, paid once with the first payment. Vouchers don’t apply to this amount; the 30-day guarantee covers it.

Payment is made at the start of each period through Stripe, using the payment methods it offers. The subscription renews automatically at the end of each period, for the same term, until it is cancelled. The invoice for each payment is issued by our team and sent by email.

4. Vouchers

A voucher gives the discount and duration set when it was created (for example, a percentage for a number of months). It is applied at purchase, belongs to the company that uses it and cannot be exchanged for cash. It may have a maximum number of uses and an expiry date. Once applied to a subscription, it keeps the conditions it was applied with.

5. 30-day guarantee

If you’re not happy within the first 30 days after your first payment, email us at hello@prevvia.com: we’ll refund what you paid, using the same payment method, and the subscription ends. The guarantee applies to each company’s first subscription and to the simulators bought in it.

6. Cancellation

The monthly plan has no lock-in: you can cancel at any time by emailing us at hello@prevvia.com, and the subscription ends at the end of the month already paid. On the yearly plan, cancellation takes effect at the end of the year already paid. Outside the 30-day guarantee, periods already paid are not refunded.

7. Missed payments

If a payment fails, Stripe tries again and notifies your company. If the payment is still outstanding 15 days later, Prevvia may suspend the simulators until it is made and, after 30 days, cancel the subscription.

8. Your company’s responsibilities

Provide accurate details at purchase and keep them up to date; only use logos, images and text you have the rights to; keep your login details safe and tell us if you suspect misuse; not use the service for unlawful or misleading purposes, or to send unsolicited marketing; and have a privacy policy on your website that informs visitors about the data they leave in the simulator.

9. Estimates and prices shown

The simulator’s estimates (savings, investment) are indicative and calculated with the values your company sets or accepts, such as prices and tariffs. They are not an offer or a quote. Your company is responsible for the prices it configures and for the information and offers it gives its customers.

10. Visitor data

The contact details and answers left in the simulator belong to your company, which is the controller. Prevvia processes them on its behalf, as a processor (Article 28 GDPR), and these terms serve as the data processing agreement between the two.

The data processed are visitors’ names, emails, phone numbers and simulation answers, for as long as the subscription lasts, for the sole purpose of providing the service: receiving, storing, displaying and sending leads to your company.

Prevvia only processes the data on your company’s instructions; ensures that anyone processing it is bound by confidentiality; applies appropriate security measures; stores it on servers in the European Union (Germany); uses other processors only for hosting and email delivery, under the same obligations, and gives notice before changing them; helps your company respond to data subjects’ requests and meet its obligations; reports any data breach without delay; and, when the contract ends, returns and deletes the data as described below.

Data about your company and the people who represent it is processed by Prevvia as explained in the privacy policy.

11. Availability and changes to the service

Prevvia does its best to keep the service available and error-free, but does not guarantee uninterrupted operation: there may be maintenance, updates or third-party failures, such as hosting, network or email. We may improve and change the service, as long as we don’t reduce the essentials of what you subscribed to.

12. Intellectual property

The software, simulators, 3D scenes and design remain Prevvia’s property. While the subscription is active, your company may use them on its website, in its ads and in its communications. Your company’s brand, logo and content remain its own, and Prevvia only uses them to provide the service.

13. Liability

Prevvia is liable for damage it causes through its own fault under these terms, up to the amount your company paid in the 12 months before the event that caused it. Prevvia is not liable for loss of profit, loss of business or other indirect damage, nor for anything resulting from the prices and information your company configures or gives its customers. These limits do not apply in cases of wilful misconduct or gross negligence.

14. End of the contract and your data

When the subscription ends, the simulators stop working. For 30 days you can export your leads in the client area or ask us to export them; after that, we delete visitor data and settings, except what the law requires us to keep, such as billing records.

15. Changes to the terms and prices

We may change these terms or the prices. We’ll give at least 30 days’ notice by email, and price changes only apply from the next renewal. If you don’t agree, you can cancel before the change takes effect.

16. Governing law and disputes

These terms are governed by Portuguese law. Any dispute will be heard by the court of the district where Prevvia has its registered office, unless mandatory law provides otherwise.
