Terms of Service
Last updated: November 10, 2026
These Terms govern your use of the Avella app (formerly LumeSkin) and avellaskin.app, provided by Kazuo Corporation (“we” or “us”). They are an agreement between you and us. Contact support@uselumeskin.com with questions or requests.
1. Using Avella
By using Avella, you agree to these Terms. If you do not agree, do not use the service. Provide accurate account information and protect your sign-in credentials. Avella is not intended for children under 13. If you are below the age of legal adulthood, obtain a parent or guardian’s permission where required by law.
2. Not Medical Advice
Avella provides AI-powered skin analysis, product information, and general skincare guidance for informational purposes only. It is not a medical device and does not diagnose, treat, cure, or prevent any disease or condition.
- Results can be wrong or incomplete. Lighting, camera quality, makeup, and filters can affect them.
- Do not use Avella in place of professional advice. Talk to a dermatologist or other qualified health professional about skin concerns, before starting or stopping a treatment, and about any spot or change that worries you, such as one that grows, bleeds, itches, or changes quickly.
- In an emergency, contact your local emergency services.
- Product safety scores and ingredient information are based on available data, which may be incomplete or out of date. Check product labels, patch test new products, and follow the manufacturer’s directions.
3. AI Features
Skin analysis, routines, product checks, and chat replies are generated by AI and may be inaccurate, incomplete, or unsuitable for you. Use your own judgment; you are responsible for decisions you make based on them. To provide these features, we process your photos, skin profile, and messages with AI providers as described in our Privacy Policy.
4. Products and Retailer Links
Avella may show products, prices, and links to third-party retailers. Prices, availability, and product details come from retailers or data providers and may change. Purchases you make from a retailer are between you and that retailer, under its terms. We may earn a commission from some purchases made through links in Avella. Showing a product does not mean we endorse it.
5. Communications
We do not send marketing emails. With your permission, Avella sends push notifications, such as routine and progress reminders, which you can turn off in your device settings. We may also contact you about sign-in, security, billing, support, and important service or legal notices related to your account.
6. License and App Stores
The App Store version is licensed under Apple’s Standard End User License Agreement, unless an applicable custom license is provided. These Terms supplement that license for our services. For other versions, we grant you a limited, non-exclusive, non-transferable license for personal, non-commercial use, subject to these Terms. Applicable store terms also apply. Apple is not a party to these Terms.
7. Acceptable Use
Do not use Avella unlawfully; upload photos of other people without their permission, or of children; upload sexual, abusive, or otherwise harmful content; distribute malicious code; disrupt the service; or access accounts without permission. Do not copy or reverse engineer our software except where applicable law permits. Report abuse to support.
8. Ownership and Your Content
Our software, branding, and supplied content belong to us or our licensors. You retain your rights in the photos, messages, and other content you submit. You grant us a non-exclusive, worldwide, royalty-free license to host, store, reproduce, process, and display that content only as needed to operate Avella and provide the features you use. Our service providers, including AI providers, may process it for those purposes. You must have the rights and permissions needed to submit it. Retention and deletion are described in our Privacy Policy; this license lasts only as needed for those purposes and lawful retention.
9. Privacy and Account Deletion
Our Privacy Policy explains collection, sharing, permissions, retention, and your privacy rights. Accepting these Terms does not by itself give consent to optional tracking or recording.
Delete your account through Settings → Delete Account in Avella, or email support. Requests may require identity verification and manual processing. Account deletion does not automatically cancel an Apple subscription; manage it through the App Store.
10. Purchases and Subscriptions
Paid features, price, billing period, and any trial or introductory offer are shown before purchase. Subscriptions renew automatically for the selected period until canceled. Trials convert to the disclosed paid subscription unless canceled by the stated deadline. Billing is handled by the platform used for your purchase.
11. Cancellation and Refunds
Cancel through the purchasing account before the applicable renewal or trial deadline, and confirm cancellation with the billing provider. Paid access normally continues until the paid period ends; trial access may end sooner. Deleting the app does not stop billing.
Stopping renewal and requesting a refund are separate. Request refunds through the store’s refund process, or contact support for help exercising statutory rights. Store policies do not limit your mandatory consumer rights.
12. EU and UK Withdrawal Rights
EU and UK consumers may have a right to withdraw within 14 days of entering into a purchase contract. For digital content supplied immediately, this right may be lost only when supply begins after the required express consent, acknowledgement, and confirmation. For services started at your express request, a proportionate charge may apply for services already supplied; starting the service does not itself end the withdrawal right. Using Avella does not by itself waive these rights.
You may use the purchasing store’s withdrawal process, or email support with a clear withdrawal request and your account and purchase details. These rights are separate from stopping renewals and do not affect remedies for faulty or misdescribed content or services.
13. Apple Refund Data
If we use Apple’s refund-consumption reporting, we will obtain valid consent before sharing personal information about your use of purchased content to help Apple assess a refund request. Using Avella, making a purchase, or accepting these Terms does not by itself give that consent. You may withdraw consent by emailing support; once withdrawn, we will stop further sharing for this purpose. Withdrawal does not affect earlier lawful processing.
14. Changes to Avella and These Terms
We may make changes to comply with law, address security risks, fix errors, maintain compatibility, or improve functionality. We will give reasonable advance notice of material changes, unless urgent security or legal reasons prevent this, and obtain consent where required. Changes will not impose additional charges without the notice and agreement required by law and the billing platform. Where consumer law requires, changes will be made without additional cost, and we will provide advance notice in a form you can save and explain your right to end the contract or receive a refund.
15. Suspension and Termination
We may restrict access for a material breach of these Terms, unlawful activity, a significant risk to users or the service, or discontinuation of the service. We will give reasonable notice and an opportunity to resolve a remediable breach where appropriate. Serious breaches, security risks, or legal requirements may require immediate action. Contact support to ask for a review. Suspension or termination does not remove statutory refund or other consumer rights.
16. Consumer Rights and Disclaimers
Nothing in these Terms excludes or limits statutory consumer rights or remedies, including applicable rights to conformity, reasonable care and skill, cancellation, repair, price reduction, or refunds. Subject to those rights, Avella is provided “as is” and “as available”; we do not promise uninterrupted or error-free operation, or that results will be accurate. Any warranty disclaimer applies only to the extent permitted by law.
17. Liability
We do not exclude or limit liability for fraud, death or personal injury caused by negligence, or any liability that cannot lawfully be excluded or limited. Subject to this and your statutory rights, we are not liable for unforeseeable losses or business losses arising from use of this personal, non-commercial service.
18. Governing Law
California law governs these Terms, except where mandatory law provides otherwise. This choice does not deprive consumers of mandatory protections that apply in their country of habitual residence or prevent them from using courts available under applicable consumer law.
