Undertona Terms of Use
Effective and last updated September 13, 2026.
These Terms of Use (the "Terms") are a legally binding agreement between you and the operator of Undertona ("Undertona", "we", "us" or "our"). They govern your access to and use of the Undertona mobile application (the "App"), the website at undertona.com (the "Site"), and any related features, content, purchases and services (together, the "Service"). Please read them carefully.
Summary, not a substitute for the full Terms: Undertona gives cosmetic color and makeup suggestions generated with AI. Results are opinions, not facts, and are not medical advice. Subscriptions renew automatically through Apple until you cancel. Purchases are billed and refunded by Apple. Only upload photos of yourself, or of people who have given you permission. Section 18 and Section 19 limit our liability.
1. Agreement to these Terms
By downloading, installing, accessing or using the Service, or by making a purchase in the App, you confirm that you have read, understood and agree to be bound by these Terms and by our Privacy Policy, which is incorporated into these Terms by reference. If you do not agree, do not use the Service.
If you use the Service on behalf of another person or an organization, you represent that you are authorized to accept these Terms on their behalf, and "you" refers to both you and that person or organization.
2. Eligibility
You must be at least 13 years old to use the Service. If you are under 18, or under the age of legal majority where you live, you may use the Service only with the involvement and consent of a parent or legal guardian, who agrees to these Terms on your behalf and is responsible for your use, including any purchases.
You may not use the Service if you are barred from doing so under the laws of the United States or any other applicable jurisdiction, or if we have previously terminated your access.
3. The Service
Undertona is an AI powered beauty and styling consultant. Depending on the features available to you, the Service lets you:
- Color Season: estimate which of twelve seasonal color palettes suits your natural coloring, with suggested colors, neutrals, metals and makeup shades.
- Glow Up: receive a step by step makeup routine for a look you choose, based on features visible in your photo.
- Skin & Undertone: receive cosmetic observations about skin type, undertone and face shape, with a simple routine.
- Get Their Look: upload an inspiration image and receive suggestions for adapting that look to your own features.
- Save results to a looks journal, share results as images, and read educational guides and articles.
Each analysis of a photo is a "scan". Features, limits and content may differ between the free and paid versions of the Service and may change over time as described in Section 16.
4. Your account
Undertona works without a sign-up form. When you first open the App, we set up a private account for you on your device, so you can start right away without giving us an email address or password. Your saved results, journal, scan allowance and scan pack balance belong to that account.
Sign in with Apple. You can choose to sign in with Apple at any time, for example under You in the App. This backs up your account so you can get it back on a new or reset device by signing in with the same Apple ID. We receive only a unique identifier from Apple; we do not request your name or email address. If you sign in on a device where you have already used Undertona without signing in, the results, journal entries and scan packs from that device are added to your existing account.
- You are responsible for all activity that happens through your device and account, and for keeping your device and Apple ID secure.
- If you have not signed in with Apple and you delete the App, reset or lose your device, we may be unable to recover your saved results or any unused scan pack balance. Active subscriptions can always be restored with Restore purchases in the App while signed in to the same Apple ID.
- Signing out of Undertona keeps your account backed up. Deleting your account, as described in Section 17, removes it permanently and disconnects Sign in with Apple.
- Any information you provide, such as an optional first name or onboarding answers, must be accurate and must not infringe anyone's rights.
- Accounts are personal. You may not sell, transfer or share your account or its scan balance.
5. Subscriptions and billing
Undertona Pro is an auto-renewing subscription available on weekly and yearly plans. The price, billing period and currency of each plan are shown in the App before you confirm your purchase and may vary by country. Unless stated otherwise in the App, Undertona Pro includes up to 10 scans in any rolling seven-day period across all scan types, together with the looks journal and other features we describe as part of Pro.
- Payment. All purchases in the App are processed by Apple through your Apple ID. Payment is charged to your Apple ID account when you confirm the purchase.
- Automatic renewal. Your subscription renews automatically for the same period at the then current price unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the current period.
- Managing and cancelling. You can manage or cancel your subscription at any time in your Apple ID account settings (on iPhone: Settings, your name, Subscriptions). Deleting the App or your Undertona account does not cancel a subscription. Cancellation takes effect at the end of the current billing period, and you keep Pro access until then.
- Free trials and offers. If we offer a free trial or introductory price, its terms are shown before purchase. Any unused portion of a free trial is forfeited when you purchase a subscription, where Apple applies that rule.
- Price changes. We may change subscription prices. Apple will notify you in advance as required, and where required by law or Apple's rules, will ask for your consent before a price increase applies to you. If you do not agree to a price change, you may cancel before it takes effect.
- Taxes. Prices may include or be subject to taxes as determined by Apple and applicable law.
6. Scan packs and scan allowances
- Weekly allowance. Pro scans are counted over a rolling seven-day period. Unused allowance does not roll over, has no cash value and ends when your subscription ends.
- Scan packs. Scan packs are one-time, non-renewing purchases of a set number of additional scans. Scan pack scans do not expire while your account exists, are used only after any available weekly allowance, and are not transferable between accounts.
- No cash value. Scans, allowances and scan pack balances are a limited license to use a feature of the Service. They are not property, have no monetary value, and cannot be exchanged for cash, sold or transferred, except where the law requires otherwise.
- Unusable photos and failed scans. If a photo cannot be analyzed (for example, no face is visible) or a scan fails for technical reasons, the scan is not counted against your allowance and any scan pack scan used is returned to your balance.
- Fair use. To protect the Service, we apply reasonable rate limits, such as a short pause after many scans in a row. We may limit or suspend scanning where we reasonably suspect automated use, abuse or fraud.
7. Cancellations and refunds
Because Apple processes all App purchases, we cannot issue refunds directly and do not have access to your payment details. To request a refund, visitreportaproblem.apple.com. Refund decisions are made by Apple under its policies. Except where required by applicable law, payments are non-refundable and we do not provide refunds or credits for partial subscription periods, unused scans or unused scan pack balances.
If you live in a country that gives consumers a statutory right to withdraw from or cancel a purchase, nothing in these Terms limits that right. Where you request immediate access to digital content, you may lose that right once the content has been supplied, to the extent permitted by law.
8. Your photos and content
"Your Content" means the photos you submit (selfies and inspiration images), any text or answers you provide, and the results saved to your account. As between you and us, you own Your Content.
You grant us a worldwide, non-exclusive, royalty-free license to host, process, transmit, analyze and display Your Content solely as needed to operate and provide the Service to you, including sending photos to the third-party AI providers described in Section 14 and our Privacy Policy. This license ends when Your Content is deleted, except for results you have already chosen to share with others. We do not use your photos for advertising, we do not sell them, and we do not use them to train AI models.
How photos are handled. Before your first scan, the App asks for your permission to send your photo to a third-party AI service. Photos are processed to create your result and then discarded; Undertona does not store your photos. Only the text result of a scan is saved to your account. See ourPrivacy Policy for details.
You represent and warrant that:
- any photo of a person that you submit is of yourself, or you have that person's permission (and, for anyone under 18, the permission of their parent or guardian) to submit it for analysis;
- you have the rights needed to submit any inspiration image, and doing so does not infringe any copyright, trademark, privacy, publicity or other right; and
- Your Content does not violate these Terms or any law.
When you share a result outside the App, for example as an image in another app, you choose who sees it, and that sharing is governed by the terms of the service you share it through.
9. AI generated results
Results are generated automatically by artificial intelligence models from a single photo and are provided for entertainment, inspiration and general styling purposes. You acknowledge that:
- Results are subjective estimates. Seasonal color analysis is a styling framework, not a scientific measurement. Results can be affected by lighting, camera settings, filters, makeup, hair dye, image quality and other factors, and may differ from the opinion of a professional color analyst or makeup artist.
- Results may be inaccurate or incomplete. AI can make mistakes, misread features, or describe things that are not present. Confidence labels are indicative only.
- Results may vary. We design the Service to give consistent answers, but scans of different photos, or of the same person in different conditions, may produce different results.
- You decide what to do with them. You are solely responsible for how you use any result, including any product you buy, cosmetic you apply or change you make to your appearance. We do not recommend or endorse specific brands or products.
- Descriptions are about color and styling only. Results are not an assessment of your worth, attractiveness, identity, ethnicity, age or health, and the Service is not designed to identify or verify any person.
10. Cosmetic information only; not medical advice
The Service provides cosmetic suggestions only. It is not a medical device and does not provide medical, dermatological or health advice, diagnosis or treatment. Observations about skin are general cosmetic observations, not a diagnosis of any condition. Always patch test new products, follow product labels, and consult a qualified healthcare professional or dermatologist about any skin concern, allergy, irritation, change in a mole or lesion, or before starting any treatment. Never disregard professional advice or delay seeking it because of something you saw in the Service.
11. Acceptable use
You agree not to, and not to help anyone else to:
- submit photos of another person without their permission, or photos of anyone under 18 without the consent of their parent or guardian;
- submit content that is sexually explicit, depicts nudity, is violent, hateful, harassing or unlawful, or that exploits or endangers minors;
- use the Service to identify, track, profile, rate, shame or harass any person;
- impersonate any person, or misrepresent results as a professional, medical or official assessment;
- copy, scrape, harvest or extract data, results or content from the Service by automated means, or use the Service to build or train a competing product or AI model;
- reverse engineer, decompile, disassemble or attempt to derive the source code, models, prompts or underlying structure of the Service, except where the law expressly permits it;
- bypass, disable or interfere with security features, scan limits, rate limits, purchase verification or other technical protections;
- access the Service through any interface other than the App or Site, or use bots, scripts or emulators to create accounts or run scans;
- upload viruses or malicious code, or interfere with or overload our systems or the systems of our providers;
- resell, sublicense, rent or commercially exploit the Service or its results without our written permission; or
- use the Service in violation of any applicable law or regulation, or of Apple's App Store terms.
12. Our intellectual property
The Service, including the App, the Site, software, design, text, color palettes, guides, articles, graphics, logos, the Undertona name and all related content (other than Your Content) is owned by us or our licensors and is protected by copyright, trademark and other laws. Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable and revocable license to install and use the App on Apple devices that you own or control, and to use the Service, for your personal, non-commercial purposes.
You may save and share the results of your own scans for personal, non-commercial purposes. All rights not expressly granted to you are reserved. You may not use our name, logos or trademarks without our prior written consent.
13. Feedback
If you send us ideas, suggestions or other feedback about the Service, you grant us a perpetual, irrevocable, worldwide, royalty-free right to use it for any purpose without obligation or compensation to you. You are not required to send feedback.
14. Third-party services
The Service relies on third parties, including:
- Apple, which distributes the App and processes all in-app payments and refunds;
- RevenueCat, which helps us verify purchases and manage subscription status;
- OpenRouter, which routes photos for analysis to AI model providers such as Google (Gemini). We configure these requests to use only providers that do not retain your photos or use them to train models; and
- hosting, infrastructure and privacy-friendly website analytics providers (such as Vercel) that help us operate the Service.
Your use of third-party services may be subject to their own terms and privacy policies. We are not responsible for third-party websites, services or content that we link to or that you choose to use, and a link does not mean we endorse them.
15. Privacy
Our Privacy Policy explains what information we collect, how we use it, and your choices, including how to delete your account and data. By using the Service, you acknowledge that we will process information as described there.
16. Changes and availability
We are continually improving the Service. We may add, change, limit or remove features, scan types, content, AI models or providers, and may release updates that you must install to keep using the App. We will try to give reasonable notice of changes that materially reduce what you have paid for. The Service may occasionally be unavailable because of maintenance, outages at our providers or events outside our control, and we do not guarantee that it will be available at all times or in every country.
17. Suspension, termination and deletion
By you. You may stop using the Service at any time. You can permanently delete your account and its data in the App underYou, then Delete account. Deletion removes your profile, scan results and journal, and any unused scan pack balance, revokes Undertona's access to your Sign in with Apple credentials, and cannot be undone. Remember to cancel any subscription separately in your Apple ID settings.
By us. We may suspend or terminate your access, with or without notice, if we reasonably believe you have breached these Terms, created risk or legal exposure for us, other users or third parties, or engaged in fraud or abuse, or if we are required to do so by law. We may also discontinue the Service entirely; if we do, we will give reasonable advance notice where possible.
Sections that by their nature should survive termination, including Sections 6 (no cash value), 8 (your warranties), 9, 10, 12, 13 and 18 through 23, will survive.
18. Disclaimers
To the fullest extent permitted by law, the Service and all results, content and information are provided "as is" and "as available", with all faults and without warranties of any kind, whether express, implied or statutory, including any implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy or quiet enjoyment, and any warranties arising from course of dealing or usage of trade. We do not warrant that the Service will be uninterrupted, secure or error-free, that results will be accurate, reliable or suited to you, or that any defects will be corrected.
Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you. Nothing in these Terms excludes rights you have as a consumer that cannot lawfully be excluded.
19. Limitation of liability
To the fullest extent permitted by law, in no event will Undertona, its operator, affiliates, licensors or service providers be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, data, goodwill or other intangible losses, or for the cost of products purchased in reliance on any result, arising out of or relating to the Service or these Terms, whether based on warranty, contract, tort (including negligence), statute or any other legal theory, even if we have been advised of the possibility of such damages.
To the fullest extent permitted by law, our total aggregate liability for all claims arising out of or relating to the Service or these Terms will not exceed the greater of (a) the amounts you paid for the Service in the twelve months before the event giving rise to the claim, or (b) fifty US dollars (US$50).
These limitations apply even if a remedy fails of its essential purpose. Some jurisdictions do not allow the limitation or exclusion of liability for incidental or consequential damages, so the above may not fully apply to you. Nothing in these Terms limits liability for death or personal injury caused by negligence, fraud, or any other liability that cannot be limited by law.
20. Indemnification
To the extent permitted by law, you agree to defend, indemnify and hold harmless Undertona and its operator, affiliates, licensors and service providers from and against any claims, liabilities, damages, losses and expenses, including reasonable legal fees, arising out of or related to (a) Your Content, including any photo you submit of another person, (b) your use or misuse of the Service, or (c) your violation of these Terms, any law or the rights of any third party.
21. Governing law and disputes
These Terms and any dispute arising out of or relating to them or the Service are governed by the laws of the State of New York, United States, without regard to its conflict of law rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.
Informal resolution first. Before filing any claim, you agree to contact us at atatahiroglu@hotmail.com with a description of the dispute and try in good faith to resolve it informally for at least 30 days.
Courts. If a dispute is not resolved informally, it will be brought exclusively in the state or federal courts located in New York County, New York, and you and we consent to the personal jurisdiction of those courts. Either party may bring an individual claim in small claims court where it qualifies. If you are a consumer living outside the United States, you may also have the right to bring proceedings in the courts of the country where you live, and nothing in these Terms deprives you of the protection of the mandatory consumer laws of that country.
To the extent permitted by law, any claim must be brought within one year after the claim arises, and all claims will be brought only in an individual capacity and not as a plaintiff or class member in any purported class or representative proceeding.
22. Apple App Store terms
If you downloaded the App from Apple's App Store, the following additional terms apply, and prevail over anything inconsistent in these Terms:
- Acknowledgement. These Terms are between you and us only, not with Apple Inc. ("Apple"). We, not Apple, are solely responsible for the App and its content.
- Scope of license. Your license to use the App is limited to a non-transferable license to use it on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the App may be accessed by other accounts associated with you through Family Sharing or volume purchasing where available.

- Warranty. We are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App (if any) to you. To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the App, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty are our responsibility, to the extent not disclaimed.
- Product claims. We, not Apple, are responsible for addressing any claims by you or any third party relating to the App or your possession and use of it, including (i) product liability claims, (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement, and (iii) claims arising under consumer protection, privacy or similar legislation.
- Intellectual property rights. In the event of any third-party claim that the App or your possession and use of it infringes that third party's intellectual property rights, we, not Apple, are solely responsible for the investigation, defense, settlement and discharge of that claim.
- Legal compliance. You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo or that has been designated by the U.S. Government as a "terrorist supporting" country, and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.

- Third-party terms. You must comply with applicable third-party terms of agreement when using the App.

23. General terms
- Entire agreement. These Terms, together with the Privacy Policy and any terms shown at the point of purchase, are the entire agreement between you and us about the Service.
- Severability. If any provision is found unenforceable, it will be enforced to the maximum extent permissible, and the remaining provisions will remain in full effect.
- No waiver. Our failure to enforce any right or provision is not a waiver of that right or provision.
- Assignment. You may not assign or transfer these Terms without our consent. We may assign them, for example in connection with a merger, acquisition or sale of assets.
- Force majeure. We are not liable for any delay or failure to perform caused by events beyond our reasonable control, including outages of third-party providers.

24. Changes to these Terms
We may update these Terms from time to time, for example to reflect changes to the Service or the law. We will post the updated Terms on this page and change the "last updated" date above. If a change is material, we will provide reasonable notice, such as a notice in the App, before it takes effect. By continuing to use the Service after the updated Terms take effect, you agree to them. If you do not agree, you must stop using the Service and cancel any subscription.
