Terms of Use

Effective Date: September 7, 2026

These Terms of Use and End User License Agreement ("Terms") are a legally binding agreement between you and Ysoftware LLC ("Ysoftware," "Avina," "we," "us," or "our") governing your access to and use of Avina, including the Avina mobile applications, https://avina.skin, https://avina.skin/app, and related services collectively referred to as the "Service."

Ysoftware LLC is located at:
4111-e Rose Lake Dr #10237
Charlotte, NC 28217
United States

Please read these Terms carefully.

THESE TERMS INCLUDE AN AGREEMENT TO RESOLVE MOST U.S. DISPUTES THROUGH BINDING INDIVIDUAL ARBITRATION AND INCLUDE A CLASS-ACTION AND JURY-TRIAL WAIVER. PLEASE REVIEW SECTION 20 CAREFULLY. YOU MAY OPT OUT OF ARBITRATION AS DESCRIBED THERE.

By creating an account, expressly accepting these Terms, purchasing a subscription, or otherwise using the Service after being presented with these Terms, you agree to them.

If you do not agree, do not use Avina.

1. Eligibility

You must be at least 13 years old to use Avina.

If you are under the age of legal majority where you live, you represent that you have permission from a parent or legal guardian where required.

You may not use the Service if applicable law prohibits you from doing so.

2. Avina Is a Skincare Organization and Information Service

Avina provides tools that may help users:

• organize skincare routines;
• track routine completion;
• maintain a personal product Shelf;
• manage favorites, reminders, restocking, and related information;
• browse skincare products and ingredients;
• maintain cosmetic skin-profile preferences;
• create private custom products; and
• receive general or personalized skincare organization suggestions.

Avina is not medical care

Avina is provided for informational, organizational, educational, and personal-use purposes.

AVINA DOES NOT PROVIDE MEDICAL ADVICE, DIAGNOSES, TREATMENT, PRESCRIPTIONS, OR MEDICAL SERVICES.

Nothing in Avina should be treated as a substitute for advice from a qualified physician, dermatologist, pharmacist, or other healthcare professional.

Do not disregard professional medical advice or delay seeking medical care because of information displayed by Avina.

If you experience a serious reaction, allergic response, injury, or other urgent medical issue, seek appropriate professional or emergency care.

3. Product and Ingredient Information

Avina may display information concerning skincare, cosmetic, wellness, or related products, including:

• names;
• brands;
• ingredients;
• categories;
• sizes;
• images;
• descriptions;
• barcodes;
• routine suggestions; and
• ingredient information.

Product formulations, ingredient lists, packaging, claims, availability, instructions, and other information can change without notice.

Although we work to provide useful information, we do not guarantee that catalog information is accurate, complete, current, error-free, or appropriate for your individual circumstances.

Ingredient lists and other product details shown in Avina may be incomplete, outdated, or incorrect. They may not reflect reformulations, regional differences, or other changes made by the manufacturer.

Always read the actual product label before buying or using a product. Do not rely on Avina for information that matters to your health or safety, including ingredient lists and allergen information. This matters most if you have an allergy, a sensitivity, a skin condition, or any other reason to avoid a specific ingredient.

If anything shown in Avina conflicts with the product’s own packaging or the manufacturer’s own information, the packaging and the manufacturer control.

You are responsible for deciding whether a product is suitable for you.

Individual results, sensitivities, tolerances, and reactions vary.

4. Third-Party Brands and Products

Ysoftware does not manufacture the third-party skincare or cosmetic products referenced through Avina.

Unless we expressly state otherwise:

• Ysoftware is not affiliated with, endorsed by, sponsored by, or certified by the brands or manufacturers displayed in Avina;
• reference to a product or brand does not imply an endorsement or commercial relationship;
• third-party product names, logos, packaging, trademarks, and other proprietary material belong to their respective owners; and
• Ysoftware does not warrant or guarantee the safety, quality, effectiveness, legality, availability, or performance of a third-party product.

Any dispute relating directly to the manufacture, sale, labeling, condition, performance, or use of a third-party product should be directed to the appropriate manufacturer, seller, or other responsible party where applicable.

5. Your Account

You may need an Avina account to use some or all of the Service.

You agree to:

• provide information that is accurate to the extent you choose or are required to provide it;
• maintain control of your authentication methods;
• not allow unauthorized access to your account; and
• promptly contact us if you believe your account has been compromised.

You are responsible for activity conducted through your account to the extent permitted by law.

You may not impersonate another person or create an account for fraudulent or abusive purposes.

6. License to Use Avina

Subject to these Terms, Ysoftware grants you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use Avina for your personal, non-commercial use.

You may not:

• copy, reproduce, sell, license, distribute, or commercially exploit the Service except as expressly permitted;
• reverse engineer, decompile, disassemble, or attempt to derive source code except where applicable law expressly permits it;
• bypass security, access controls, subscription restrictions, or technical limitations;
• scrape, harvest, or systematically extract the Avina catalog or database;
• use bots or automated systems to access the Service in a manner we have not authorized;
• interfere with the Service or another user’s access;
• upload malicious code;
• access another person’s account without authorization;
• use Avina to violate law or third-party rights; or
• misuse Avina’s trademarks, copyrighted material, catalog, design, software, or other intellectual property.

7. Your Content

You retain ownership of content you create and provide to Avina, such as private notes and custom-product photographs, subject to rights belonging to third parties.

You grant Ysoftware a limited, non-exclusive, worldwide, royalty-free license to host, store, reproduce, process, resize, transmit, and display your content solely as reasonably necessary to:

• provide the Service to you;
• maintain, secure, support, and troubleshoot Avina;
• comply with your requests;
• comply with law; and
• exercise rights described in these Terms and the Privacy Policy.

This license ends when the relevant content is deleted from our active systems except to the extent temporary retention is technically necessary or legally required.

You represent that you have the right to provide content you upload and that your use of the Service will not infringe another person’s rights.

8. Avina Premium, Subscriptions, and Payments

Some or all Avina functionality may require an active paid subscription or trial.

Available prices, billing periods, free trials, promotions, renewal terms, and features are displayed before you complete a purchase. Those purchase-screen terms form part of your subscription agreement.

Automatic renewal

Unless expressly stated otherwise, subscriptions automatically renew at the end of each billing period until cancelled.

You authorize the applicable billing provider to charge the then-applicable subscription price and any applicable taxes at each renewal.

Trials

If Avina offers a free or discounted trial, the subscription may automatically convert to a paid subscription when the trial ends unless you cancel before the deadline shown at purchase.

Eligibility for promotional trials may be limited.

iOS purchases

Subscriptions purchased through the Apple App Store are billed and managed by Apple and are subject to Apple’s applicable purchase and subscription terms.

Cancellation and refund requests for Apple-billed purchases generally must be managed through Apple.

Android purchases

Subscriptions purchased through Google Play are billed and managed through Google and are subject to Google’s applicable purchase and subscription terms.

Cancellation and refund requests for Google-billed purchases generally must be managed through Google Play.

Web purchases

Web subscriptions are processed through Stripe or the web billing interface Avina makes available.

Web subscribers may be able to manage or cancel their subscription through Avina’s web billing or account-management interface.

Subscription management

Where supported, RevenueCat may be used to synchronize subscription status and premium entitlements.

Your billing provider, purchase method, and applicable platform determine how billing changes, cancellations, and refunds are handled.

Deleting your account and your subscription

Deleting your Avina account does not automatically cancel a subscription billed by Apple, Google Play, or another third-party billing provider.

You must separately cancel such a subscription through the platform through which it was purchased.

A subscription purchased on the web through Avina’s billing interface is cancelled when you delete your Avina account. It ends at the close of the billing period already paid for, and no further charges are made.

If you delete your Avina account while a subscription remains active, you may lose access to the Avina account associated with that subscription.

Refunds

Except where applicable law requires otherwise, subscription charges are non-refundable once charged.

Refund eligibility for purchases processed by Apple or Google is governed by the applicable store’s policies.

Web refund requests may be evaluated under applicable law and any refund policy displayed at purchase.

Nothing in this section limits refund or cancellation rights that cannot legally be waived.

9. Changes to Pricing and Features

We may change subscription prices, features, plans, or availability.

Any price change for an existing automatically renewing subscription will be handled in accordance with applicable law and the rules of the applicable billing provider.

We may add, modify, discontinue, or replace features where reasonably necessary to develop, maintain, secure, or operate Avina.

10. Privacy

Our Privacy Policy explains how we process information and is available at: https://avina.skin/privacy

By accepting these Terms, you acknowledge that you have been given access to the Privacy Policy.

Where applicable law requires separate consent for a particular data practice, acceptance of these Terms does not replace that consent.

11. Notifications

If you enable reminders or notifications, you authorize Avina to deliver the notifications you request.

Notifications may contain information such as routine or product names and may be visible on a device lock screen depending on your settings.

You are responsible for configuring notification privacy settings appropriate for your circumstances.

12. Intellectual Property

Avina, including its software, user interface, designs, illustrations, original graphics, text, databases, arrangement of content, trademarks, logos, and other Ysoftware-owned materials, is owned by Ysoftware or its licensors and is protected by applicable intellectual-property laws.

Except for the limited license granted under these Terms, no rights are transferred to you.

Third-party trademarks and product materials remain the property of their respective owners.

13. Copyright and Intellectual Property Complaints

If you believe material available through Avina infringes your copyright, trademark, or other intellectual-property rights, contact: support@avina.skin

Include enough information for us to identify:

• the protected work or right;
• the allegedly infringing material;
• where the material appears;
• your contact information;
• the basis for your claim; and
• any other information reasonably necessary for us to investigate.

We may remove, restrict, replace, or investigate disputed material as appropriate.

14. Third-Party Services

Avina may integrate with or rely on third-party providers, including app stores, authentication providers, payment processors, hosting providers, analytics providers, and other infrastructure services.

We do not control third-party services and are not responsible for their independent acts, outages, terms, policies, or services to the extent permitted by law.

Your use of third-party services may be subject to separate terms.

15. Availability and Changes to the Service

We aim to provide a reliable Service, but we do not guarantee that Avina will always be:

• available;
• uninterrupted;
• secure;
• error-free;
• compatible with every device;
• free from data loss; or
• maintained indefinitely.

We may perform maintenance or suspend portions of Avina where reasonably necessary.

We may discontinue the Service or a feature, subject to applicable consumer-law obligations.

16. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, AVINA IS PROVIDED "AS IS" AND "AS AVAILABLE."

Ysoftware disclaims warranties and representations not expressly stated in these Terms, including implied warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, availability, and quiet enjoyment, to the extent such warranties may legally be disclaimed.

Without limiting the foregoing, we do not warrant that:

• skincare or product information will be accurate or complete;
• a particular routine or product will achieve any result;
• use of Avina will improve your skin or health;
• a product will be safe or suitable for you;
• the Service will always be available or error-free; or
• third-party products or services will perform as represented by their manufacturers or providers.

Some jurisdictions do not permit certain warranty exclusions. In those jurisdictions, these exclusions apply only to the extent permitted by law.

17. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, YSOFTWARE LLC AND ITS MEMBERS, MANAGERS, EMPLOYEES, CONTRACTORS, AFFILIATES, LICENSORS, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, REVENUE, GOODWILL, USE, OR DATA, ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS.

To the maximum extent permitted by applicable law, Ysoftware’s total aggregate liability arising out of or relating to Avina or these Terms will not exceed the greater of:

• the amount you paid to Ysoftware for Avina during the twelve months immediately preceding the event giving rise to the claim; or
• USD $100.

These limitations apply regardless of the legal theory asserted and even if a remedy fails of its essential purpose, to the extent permitted by law.

Nothing in these Terms excludes or limits liability that applicable law does not permit us to exclude or limit, including mandatory consumer protections.

18. Indemnification

To the extent permitted by applicable law, you agree to indemnify and hold harmless Ysoftware LLC and its personnel from third-party claims, liabilities, damages, and reasonable costs arising from:

• your unlawful misuse of Avina;
• content you provide that infringes another person’s rights;
• your material violation of these Terms; or
• fraud or intentional misconduct by you.

This section does not require you to indemnify Ysoftware for Ysoftware’s own unlawful conduct and does not apply where prohibited by consumer law.

19. Suspension and Termination

You may stop using Avina at any time.

You may delete your account through the methods described in our Privacy Policy.

We may suspend or terminate access if we reasonably believe that you:

• materially violated these Terms;
• used Avina fraudulently or unlawfully;
• compromised the security or integrity of the Service;
• attempted unauthorized access; or
• created material risk to Ysoftware, another user, or a third party.

Where appropriate and legally required, we may provide notice or an opportunity to cure before termination.

Sections that by their nature should survive termination will survive, including provisions concerning intellectual property, disclaimers, liability, disputes, and amounts owed.

20. U.S. Dispute Resolution, Arbitration, and Class-Action Waiver

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS.

This section applies to users in the United States to the maximum extent permitted by applicable law.

A. Informal dispute resolution

Before either party starts arbitration, the party bringing the dispute must first send the other party a written notice describing:

• the name and contact information of the person bringing the dispute;
• the relevant Avina account email, if applicable;
• the facts giving rise to the dispute; and
• the relief requested.

Notices to Ysoftware must be sent to: support@avina.skin with the subject line Legal Dispute Notice.

The parties will attempt in good faith to resolve the dispute informally for at least 30 days after receipt of a complete notice before starting arbitration.

This requirement does not prevent either party from seeking urgent temporary relief where necessary to prevent immediate harm.

B. Agreement to individual arbitration

Except for the exclusions below, you and Ysoftware agree that disputes arising out of or relating to Avina, these Terms, or your relationship with Ysoftware will be resolved by binding individual arbitration, rather than by a judge or jury in court.

The arbitration will be administered by the American Arbitration Association ("AAA") under its applicable Consumer Arbitration Rules and Mediation Procedures, as modified by these Terms.

If AAA is unable or unwilling to administer the arbitration, the parties will attempt to agree on another recognized arbitration provider. If they cannot agree, a court of competent jurisdiction may appoint an arbitrator as permitted by law.

The arbitration may occur remotely, by documents, or in Wake County, North Carolina, subject to applicable AAA rules, applicable law, and any location rights the consumer cannot waive.

C. Arbitration fees

Payment of filing, administration, and arbitrator fees will be governed by the applicable AAA Consumer Arbitration Rules and fee schedule.

Ysoftware will pay fees it is required to pay under those rules or applicable law.

D. Exceptions

Either party may bring an individual claim in an appropriate small-claims court if the claim qualifies.

Either party may seek temporary or injunctive relief in court concerning actual or threatened infringement, misuse, or unauthorized access involving intellectual property or the security of the Service where such relief is legally available.

E. No class actions

YOU AND YSOFTWARE AGREE THAT, TO THE MAXIMUM EXTENT PERMITTED BY LAW, EACH PARTY MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF, CLASS MEMBER, PRIVATE ATTORNEY GENERAL, OR REPRESENTATIVE IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING.

An arbitrator may award relief only to the individual party seeking relief and only to the extent necessary to resolve that individual’s claim, except where applicable law requires otherwise.

F. Jury-trial waiver

To the extent a dispute is subject to arbitration, you and Ysoftware waive the right to a trial before a judge or jury.

G. Arbitration opt-out

You may opt out of this arbitration agreement without affecting the rest of these Terms.

To opt out, email support@avina.skin within 30 days after you first accept the version of these Terms containing this arbitration provision.

Use the subject line: Arbitration Opt-Out

Your notice must include:

• your full name;
• the email associated with your Avina account; and
• a clear statement that you are opting out of the Avina arbitration agreement.

Opting out applies only to arbitration. The remaining Terms continue to apply.

H. Severability

If a court determines that a particular part of this arbitration section cannot legally be enforced, that portion will be severed to the minimum extent necessary, and the remainder will continue to apply, unless applicable law requires otherwise.

If the class-action waiver is found unenforceable as to a particular claim and that determination cannot be severed consistently with applicable law, that claim will proceed in a court of competent jurisdiction rather than in class arbitration.

21. Governing Law and Courts

Except where Section 20 applies, these Terms are governed by the laws of the State of North Carolina, without regard to conflict-of-law principles.

For disputes that are not required to be arbitrated and may legally be subject to a contractual venue provision, you and Ysoftware consent to the state and federal courts with jurisdiction in Wake County, North Carolina.

Nothing in these Terms deprives you of mandatory consumer protections or a forum right that cannot legally be waived under the laws applicable to you.

22. Users Outside the United States

If you access Avina from Canada, the United Kingdom, or another jurisdiction, mandatory local consumer protections may apply.

Nothing in these Terms is intended to waive rights that applicable law does not permit you to waive.

Where a provision conflicts with a mandatory law applicable to you, the mandatory law controls only to the extent of the conflict.

23. Apple App Store Terms

If you access Avina through Apple’s App Store, the following terms also apply to the extent required by Apple:

• these Terms are between you and Ysoftware, not Apple;
• Ysoftware, not Apple, is responsible for Avina and its content;
• your license to use the iOS application is non-transferable and limited to Apple-branded products you own or control, subject to Apple’s applicable Usage Rules, including any permitted Family Sharing or similar use;
• Ysoftware is responsible for maintenance and support for Avina as required by these Terms or applicable law, and Apple has no obligation to provide maintenance or support;
• to the extent any warranty concerning the iOS application cannot legally be disclaimed and the application fails to conform to that warranty, you may notify Apple and Apple may refund the purchase price paid for the application, if any, as provided by Apple’s applicable terms;
• Ysoftware, not Apple, is responsible for addressing claims relating to Avina, including product-liability, legal-compliance, consumer-protection, and privacy claims;
• Ysoftware, not Apple, is responsible for investigating, defending, settling, and resolving third-party intellectual-property claims relating to Avina;
• you represent that you are not located in a country subject to an applicable U.S. government embargo or otherwise prohibited from receiving the application under applicable export-control law;
• you must comply with applicable third-party terms when using Avina; and
• Apple and its subsidiaries are third-party beneficiaries of this section and may enforce these App Store-specific terms against you.

24. Export and Legal Compliance

You agree to use Avina in compliance with applicable laws and regulations.

You may not use, export, or re-export Avina in violation of applicable United States export controls, sanctions, or other trade restrictions.

25. Changes to These Terms

We may update these Terms from time to time.

If we make a material change, we may provide notice and may require you to accept the updated Terms before continuing to use some or all of Avina.

The Effective Date identifies the version currently in effect.

Continued use after an update constitutes acceptance only where legally sufficient. Where express renewed acceptance is appropriate, Avina may require it.

26. Assignment

You may not transfer your rights or obligations under these Terms without our consent.

Ysoftware may assign these Terms as part of a merger, acquisition, corporate reorganization, financing, sale of assets, or similar transaction, subject to applicable law.

27. Entire Agreement

These Terms, the Privacy Policy, and any additional terms expressly presented for a particular feature or purchase constitute the agreement between you and Ysoftware concerning the Service.

If purchase terms presented by Apple, Google, Stripe, or another payment provider conflict with these Terms regarding that provider’s billing process, the applicable provider’s mandatory billing rules control for that transaction.

28. No Waiver

If Ysoftware does not immediately enforce a provision of these Terms, that does not waive the right to enforce it later.

29. Severability

Except as specifically provided in the arbitration section, if any provision of these Terms is held invalid or unenforceable, it will be modified or severed to the minimum extent necessary and the remaining provisions will continue in effect.
