Terms.
These Terms of Service govern your use of the mobile applications and related services published by VAST FLOW ("we", "our", "us"). They apply uniformly to every application we publish on the Apple App Store and Google Play, whether the application captures photographs of your face, skin, hair, scalp, body, product labels, or documents, analyses that imagery, or helps you track health and wellness information such as diet, caffeine, sleep, or activity, including through Apple Health. By downloading, installing, or using any of our applications you agree to be bound by these Terms; if you do not agree, do not use the application.
C.1The agreement and how it is formed
These Terms form a binding contract between you and VAST FLOW. They incorporate by reference (a) our Privacy Policy (appendix B), which describes how we process data, and (b) the Apple Licensed Application End User License Agreement (the "Apple EULA") for applications downloaded from the App Store. Where any provision of the Apple EULA conflicts with these Terms in a way that affects your rights against Apple, the Apple EULA governs the relationship between you and Apple, and these Terms govern the relationship between you and us. Applications downloaded from Google Play are licensed to you under the standard end-user terms published by Google, supplemented by these Terms.
C.2Who may use the application
You must be at least thirteen years old (or the higher minimum age set by the law where you live) to use our applications. Several of our applications are rated 17+ in the App Store because they discuss adult skincare, haircare, or wellness topics; for those applications, you must be at least seventeen. If you are under the age of majority in your jurisdiction, you must have your parent's or legal guardian's permission to use the application, and they accept these Terms on your behalf.
C.3Licence to use the application
Subject to your compliance with these Terms, we grant you a personal, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use the application on devices you own or control, solely for your own personal, non-commercial use. The application and all of its content — software, designs, text, graphics, audio, the trade marks "VAST FLOW" and our product names, and all related intellectual property — remain our property or the property of our licensors, and no rights other than the limited licence in this section are granted to you.
C.4Acceptable use
You agree not to:
- Use the application for any purpose that is unlawful in your jurisdiction.
- Submit images of any person without their informed consent, in particular images of children unless you are their parent or legal guardian.
- Submit images of identity documents, passports, financial cards, or other materials whose photography or transmission is restricted by law.
- Use the application to attempt to identify, profile, surveil, or harass any specific person.
- Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the application, except to the extent this restriction is prohibited by applicable law.
- Bypass, disable, or interfere with security features, rate limits, free-tier quotas, subscription validation, or the integrity of any part of the service.
- Use automated means (bots, scrapers, scripts) to access the application's backend, or use the application's AI features as a passthrough to extract data from the underlying third-party AI service.
- Resell, redistribute, or commercially exploit the application or any of its outputs without our prior written permission.
C.5Your content and what we may do with it
"Your Content" means anything you submit through the application — photographs you capture, profile information you enter, free-text responses to quizzes, and any other material you provide. You retain ownership of Your Content. By submitting Your Content you grant us a worldwide, non-exclusive, royalty-free licence to process Your Content for the limited purposes of (i) generating the analysis or output you requested, (ii) routing it to the third-party AI service that produces the analysis (see appendix B, §B.5), and (iii) operating, securing, and improving the application. We do not use Your Content for advertising, training of AI models, or for any other purpose not described in these Terms or in the Privacy Policy. The licence terminates when Your Content is deleted from our systems and from the systems of our processors, save where retention is required to comply with law.
C.6Free tier, subscriptions, and auto-renewal
Many of our applications are free to download and offer a limited free tier together with a paid subscription that unlocks additional features or a higher usage quota. Subscriptions are processed exclusively by the operator of the application store from which you downloaded the application (currently the Apple App Store and Google Play) under their standard billing terms.
C.6.1 Auto-renewal
Subscriptions are automatically renewable. Unless you turn off auto-renewal at least twenty-four hours before the end of the current period, your subscription renews automatically at the then-current price and your payment method is charged within twenty-four hours of the end of the current period. The renewal price, currency, and frequency are displayed in the application before purchase and on the App Store or Play Store subscription page.
C.6.2 Managing your subscription
You can view, modify, or cancel your subscription at any time from the subscription-management screen of the App Store (Settings → [your name] → Subscriptions on iOS) or Google Play (Play Store → Profile → Payments & subscriptions → Subscriptions). Cancellation takes effect at the end of the current paid period; you retain access until then.
C.6.3 Refunds
All payments are non-refundable except where refund is required by applicable consumer-protection law. Refund requests are handled by Apple (apple.com/legal/itunes/ww — "Report a Problem") or by Google Play according to their respective policies; we do not process refunds directly because we do not process payments directly.
C.6.4 Price changes
We may change the price of a subscription. Existing subscribers will be notified of a price change before it takes effect on their next renewal and may cancel to avoid the new price.
C.6.5 Free trials
Where an application offers a free trial period, the trial converts automatically into a paid subscription at the end of the trial unless cancelled at least twenty-four hours before the end of the trial. A given user is eligible for a free trial only once per application, per platform account.
C.7Health and wellness disclaimer — not medical advice
This section is fundamental. Read it carefully.
Several of our applications discuss skin, hair, scalp, body, nutrition, fitness, or general wellness. Any analysis, score, recommendation, ingredient assessment, routine suggestion, condition label, or other output generated by an application is provided for informational and educational purposes only and is not a medical diagnosis, medical advice, medical treatment, or a substitute for the judgement of a licensed healthcare professional. Our applications are not medical devices, are not registered with the U.S. Food and Drug Administration, the European Medicines Agency, the UK MHRA, or any equivalent regulator, and are not intended to diagnose, treat, cure, mitigate, or prevent any disease or medical condition.
The outputs of our applications are generated by general-purpose artificial-intelligence models trained on broad corpora and may contain errors, omissions, or recommendations unsuitable for your particular situation. You should:
- Consult a qualified medical professional — a dermatologist, trichologist, physician, dietitian, or other licensed specialist as appropriate — before acting on any recommendation produced by the application.
- Seek immediate professional medical attention if you observe a skin lesion, mole, sore, bleeding, persistent rash, persistent hair loss, or any other symptom that may indicate a serious condition. Do not rely on the application to evaluate whether a symptom is benign.
- Discontinue any product or routine that causes irritation, allergic reaction, or other adverse effect, and consult a professional.
Where an application provides estimates or numerical figures — for example, an estimate of the caffeine remaining in your body computed from a general population-average half-life, or an analogous nutrition, activity, or wellness calculation — those figures are informational and educational only. They are not a medical measurement, are not personalised to your individual metabolism or physiology, and must not be relied upon for medical decisions.
Where the application surfaces references to scientific literature, dermatology associations, or public-health sources, those references are provided for your further reading and do not imply that the authors of the cited sources endorse the application or its outputs. We do not guarantee that information cited in the application is up to date at the time you read it; you should consult the original sources for current information.
C.8Third-party AI processing
Our applications use third-party artificial-intelligence services to generate analyses, as described in detail in the Privacy Policy (appendix B, §B.5). Before any user data is transmitted to such a service for the first time, the application displays an in-app consent screen that names the service provider and lists what will be sent; no transmission occurs until you affirmatively accept. You may withdraw consent at any time from the application's settings, in which case features that require third-party AI processing will be disabled while the rest of the application continues to function. You acknowledge that the third-party AI service is operated by an independent provider whose terms and policies apply to its handling of the data, and that the analysis it produces may contain errors as described in §C.7.
C.9Permissions on your device
Our applications request access to certain device features only when you choose to use a feature that requires them — typically the camera (to capture an image for analysis), the photo library (to select an existing image), and, for applications that integrate with Apple Health, read or write access to the specific HealthKit data types the feature needs. The application explains the purpose of each permission in the in-app screen that immediately precedes the system permission request. You may grant or deny each permission at the system level; denying a permission disables the corresponding feature but does not affect other parts of the application. You can revoke any granted permission at any time from your device's settings.
C.10Service availability and changes
The application is provided as a service that depends on our servers and on third-party services (Apple, Google, OpenRouter, OpenAI, Hetzner, and others described in the Privacy Policy). We do not guarantee that the service will be available without interruption, that defects will be corrected on any particular timetable, or that any specific feature will remain available indefinitely. We reserve the right to modify, suspend, or discontinue any feature, or the application as a whole, at any time. Where a discontinuation materially reduces the value of a paid subscription, we will offer a pro-rata refund of the unused portion through the App Store or Play Store mechanism.
C.11Termination
You may stop using the application and terminate this agreement at any time by uninstalling the application. We may suspend or terminate your access to the application, and any associated subscription, if you materially breach these Terms — in particular if you violate the acceptable-use rules in §C.4 — or if continued provision of the service to you would expose us to legal liability. We will give you reasonable notice of termination where the circumstances permit. Sections of these Terms that by their nature should survive termination (including §C.5 second sentence, §C.7, §C.12, §C.13, §C.14, and §C.16) survive termination.
C.12Disclaimer of warranties
To the maximum extent permitted by applicable law, the application is provided "as is" and "as available", with all faults and without warranty of any kind. We disclaim all warranties, whether express, implied, statutory, or otherwise, including without limitation any implied warranties of merchantability, fitness for a particular purpose, accuracy, non-infringement, and quiet enjoyment. We do not warrant that the application will meet your requirements, that its operation will be uninterrupted or error-free, that defects will be corrected, or that the application or the servers on which it runs are free of viruses or other harmful components. No advice or information, whether oral or written, obtained by you from us or through the application, creates any warranty not expressly stated in these Terms.
C.13Limitation of liability
To the maximum extent permitted by applicable law, in no event will VAST FLOW, its officers, directors, employees, agents, suppliers, or licensors be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including without limitation damages for loss of profits, loss of revenue, loss of data, loss of goodwill, business interruption, or cost of substitute services, arising out of or in connection with these Terms or your use of the application, whether based in contract, tort (including negligence), strict liability, or any other legal theory, and whether or not we have been advised of the possibility of such damages.
Our aggregate liability to you for all claims arising out of or in connection with these Terms or the application will not exceed the greater of (i) the amount you have paid to us for the application in the twelve months preceding the event giving rise to the claim, or (ii) ten United States dollars.
Nothing in these Terms excludes or limits our liability for fraud, fraudulent misrepresentation, death or personal injury caused by our negligence, or any other liability that cannot be excluded or limited under applicable law. If you are a consumer in a jurisdiction whose law confers rights that cannot be waived, those rights are not affected by this section.
C.14Indemnification
You agree to defend, indemnify, and hold harmless VAST FLOW and its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or in any way connected with (a) your breach of these Terms, (b) your violation of any law or the rights of a third party, including the rights of any person whose image you submitted to the application, or (c) your misuse of the application's outputs in a way that causes harm to yourself or another.
C.15Apple-specific terms
The following terms apply to applications downloaded from the Apple App Store. You acknowledge that these Terms are between you and us only, not with Apple, and that we — not Apple — are solely responsible for the application and its content. Apple has no obligation to provide any maintenance or support for the application. In the event of any failure of the application to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the application to you; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the application. We, not Apple, are responsible for addressing any claims by you or any third party relating to the application, including product-liability claims, claims that the application fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer-protection or similar legislation. We, not Apple, are responsible for the investigation, defence, settlement, and discharge of any third-party intellectual-property claim relating to the application. You represent that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties. Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
C.16Governing law and dispute resolution
These Terms are governed by the laws of the Republic of Kazakhstan, without regard to its conflict-of-laws principles, except where the law of your country of residence as a consumer mandates the application of its own consumer-protection laws. Any dispute that cannot be resolved by good-faith negotiation will be submitted to the courts of the Republic of Kazakhstan having competent jurisdiction, except where mandatory consumer-protection law of your country of residence requires that the dispute be heard by the courts of that country.
C.17Changes to these Terms
We may revise these Terms from time to time, in particular when we launch new features, change third-party processors, or respond to changes in applicable law. Material changes will be announced inside the affected applications and on this page, and the "last updated" date in the header will be revised. Your continued use of the application after the announcement constitutes acceptance of the revised Terms; if you do not accept the revision, you may stop using the application and uninstall it.
C.18Miscellaneous
If any provision of these Terms is held to be unenforceable, the remaining provisions will continue in full force and effect. Our failure to enforce any right or provision of these Terms will not be considered a waiver of those rights. These Terms, together with the Privacy Policy and any in-application notices, constitute the entire agreement between you and us regarding the application and supersede any prior agreement on the same subject matter. You may not assign or transfer your rights under these Terms; we may assign our rights to a successor in the event of a merger, acquisition, or sale of substantially all of our assets.
