Terms of Use

Mevona turns your photos into photoreal previews of cosmetic procedures and produces a Facial Dossier: a 17-section reading of your facial proportions, symmetry, features, and skin. Previews and analysis are generated with artificial intelligence and are provided for educational and informational visualization only.

Mevona is not a medical service or a medical device. The previews, dossier, and any guidance in the app are for general informational and educational purposes only. They do not constitute medical advice, diagnosis, treatment, or a prediction of surgical results.

You must be at least 18 years old to use the Service. By using it, you represent that you are 18 or older and have the legal capacity to enter into these Terms.

Mevona does not require an account, email, or login. On first launch, the app creates an anonymous identifier tied to your device so your content stays available to you. You are responsible for your device and for the content you create with the Service. See our Privacy Policy for how your information is handled.

Your first Cosmetic Preview is free. Beyond that, a Mevona Pro subscription is required to generate unlimited previews and your full Facial Dossier. Mevona Pro is offered as a weekly or yearly auto-renewable subscription.

Subscriptions are sold and billed through the Apple App Store. By subscribing, you agree that:

You can manage or cancel your subscription at any time in your Apple App Store account settings. Cancellation takes effect at the end of the current billing period; you keep access until then.

Purchases are handled by Apple. No refunds are provided for partial subscription periods. Refund requests are subject to Apple’s policies — use “Report a Problem” in your Apple purchase history or contact Apple Support.

A dossier is prepared within 24 hours of purchase. Delivery may occasionally take longer; a delay does not, by itself, entitle you to a refund. If generation fails, contact us at support@mevona.cc.

You retain ownership of the photos and inputs you provide. To operate the Service, you grant us a limited, worldwide license to store and process your content to generate your previews and dossier and to provide the Service to you. Your photos and inputs are not used for advertising. Provider-side handling is governed by the applicable provider terms and may follow retention periods different from Mevona's own storage. You are responsible for having the right to submit any photo you upload, and you must only upload photos of yourself.

You agree not to:

The Service and its original content, features, and functionality (excluding content you provide) are owned by Marius Labs and are protected by intellectual property laws. You may not copy, modify, distribute, sell, or lease any part of the Service without our written permission.

The Service relies on third parties, including Apple, Google, Anthropic, and RevenueCat. Your use of those services may be subject to their own terms. We are not responsible for the practices of third-party services.

The Service is provided “as is” and “as available” without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that any preview or analysis will be accurate or reliable.

To the maximum extent permitted by law, Marius Labs shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data or goodwill, arising from your use of the Service. To the maximum extent permitted by law, our total liability shall not exceed the greater of the amount you paid for the Service in the past 12 months or USD 100.

You agree to indemnify and hold harmless Marius Labs and its officers, directors, employees, and agents from any claims, damages, losses, or expenses arising from your use of the Service, your violation of these Terms, or your violation of any rights of another person or entity.

We may suspend or terminate your access to the Service at any time, without notice, if you breach these Terms or misuse the Service. You may stop using the Service at any time and delete your data using “Delete all face data” in Settings. Provisions that by their nature should survive termination will survive.

We may update these Terms from time to time. Material changes will be reflected by updating the “Last updated” date at the top of this page. Your continued use of the Service after changes take effect constitutes acceptance of the updated Terms.

These Terms are governed by French law, without regard to conflict-of-law principles. Any dispute relating to the Service or these Terms will be submitted to the competent courts of Paris, France. If you are a consumer, this does not deprive you of the protection afforded by the mandatory provisions of the law of your country of residence, and you may also bring proceedings before the courts of that country.

Before any legal action, you may contact us at support@mevona.cc to seek an amicable resolution. EU consumers may also use the European Commission’s Online Dispute Resolution platform at https://ec.europa.eu/consumers/odr.
