Terms of Use
Effective date: September 10, 2026 · Version 1.2 · Privacy Policy
1. Agreement
These Terms of Use (the “Terms”) are an agreement between you and the Glowtrack team (“we”, “us”) governing your use of the Glowtrack mobile application, named “Işılda” on Turkish-language devices and in the Turkish App Store, and its widget (the “App”). By downloading or using the App you accept these Terms. If you do not accept them, do not use the App.
Our Privacy Policy explains how information is handled and forms part of these Terms.
2. Who may use the App
You must be at least 16 years old, or 13 and over with the consent of a parent or guardian where local law permits, and legally able to enter into this agreement. The App is intended for your own personal, non-commercial use.
3. Licence
We grant you a personal, non-exclusive, non-transferable, revocable licence to use the App on Apple devices that you own or control, as permitted by the App Store Terms of Service. You may not copy, modify, distribute, sell or lease the App, reverse engineer it except where that restriction is prohibited by law, or use it to build a competing product.
4. Not medical advice
Glowtrack is a cosmetic and educational tool. It is not a medical device, it does not diagnose, treat, cure or prevent any condition, and nothing in it is medical advice.
The scores, skin-age bands, concern indicators, routines, ingredient ratings, product suggestions and coach messages are general information generated from photographs and from what you tell the App. They are not a substitute for examination by a dermatologist or other qualified professional.
- Consult a qualified professional before changing your skincare routine, especially if you are pregnant, breastfeeding, taking prescription treatments, or have a diagnosed skin condition.
- If you notice a mole or lesion that changes in size, shape or colour, bleeds, or does not heal, see a doctor. The App cannot detect skin cancer and does not look for it.
- If you have a medical emergency, contact your local emergency service. Do not rely on the App.
- Patch-test new products. We are not responsible for reactions to any product mentioned in the App.
5. About the analysis
Skin analysis is performed on your device from a single photograph. Results depend heavily on lighting, camera quality, angle, distance, make-up and image processing applied by your phone. Scores are relative indicators intended to show change over time under similar conditions; they are estimates, not measurements, and two photos taken minutes apart may differ.
Ingredient analysis reads the ingredient list you photograph, paste or fetch by barcode, and scores it against a dictionary shipped inside the App. Text recognition can misread small print, and ingredients that are not in our dictionary are excluded from the score rather than judged — the App shows you how many were recognised. Concentrations cannot be known from an ingredient list, so the score is an informed indication, not a laboratory assessment.
We make no promise that using the App will improve your skin or produce any particular result.
6. Subscriptions and payments
Some features require a paid subscription. Subscriptions are sold and billed by Apple through your App Store account, at the price and billing period shown to you at the time of purchase.
- Payment is charged to your App Store account at confirmation of purchase.
- Subscriptions renew automatically unless auto-renew is turned off 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.
- You can manage or cancel a subscription in iOS Settings → your name → Subscriptions. Deleting the App does not cancel a subscription.
- If a free trial is offered, any unused portion is forfeited when you purchase a subscription.
- Refunds are handled by Apple under the App Store Terms of Service. We cannot issue refunds for App Store purchases.
- We may change subscription prices or the features included in a plan. Price changes affect a renewal only after Apple has notified you and, where required, you have consented.
7. What the free and paid tiers include
The free tier includes your routine, daily check-ins, progress tracking, and a limited number of skin scans and product analyses per day. Premium adds the AI coach, unlimited skin scans, unlimited product analyses, unlimited skin experiments, and the deeper insight rules.
Fair-use limits apply to the AI coach because each message is answered by a paid third-party model on our account: Premium currently allows up to 30 coach messages per device per day. We may adjust the limits and the contents of each tier; where a change materially reduces what you already pay for, we will say so in the App before it takes effect.
8. Your content
Photos, notes, product entries and other content you create remain yours. Your photos, scans and logs are stored on your device and we have no access to them. Messages you send to the AI coach are the exception: to produce a reply they pass through our function and on to our model provider, as described in the Privacy Policy. You are responsible for the content you add, and you must not add photographs of another person without their consent.
If you choose to suggest a product for the catalog, you grant us a worldwide, royalty-free licence to use the text and, if you opted in, the front-of-pack photo you submitted, in order to add and display that product in the App's catalog. Submit only photos you took yourself and text copied from the product's own packaging.
If a future version lets you post content publicly, you will grant us a licence to display that content within the App for that purpose only, and community rules will apply: no unlawful, abusive, hateful, misleading medical or sexually explicit content, no spam, no advertising, no impersonation. We may remove content or restrict accounts that breach those rules.
9. Acceptable use
You agree not to: use the App unlawfully; interfere with or disrupt it; attempt to gain unauthorised access to any system; circumvent purchase, licence or usage-limit controls; scrape or extract its content or data systematically; use the AI coach for purposes unrelated to skincare; or use the App to provide a service to third parties.
10. Intellectual property
The App, its design, text, illustrations, mascot, icons and editorial content are owned by us or our licensors and are protected by intellectual property law. These Terms grant you no rights to our trade marks or branding. Product names of third parties are the property of their respective owners and are referenced for identification only.
11. Third-party services
The App relies on Apple's App Store and StoreKit, on Adapty for subscription state, on Supabase for the function that serves the AI coach, on Anthropic for coach replies, on Open-Meteo for climate values, and on Open Beauty Facts for barcode lookups. It may link to external websites. We are not responsible for third-party services or content, and your use of them is governed by their own terms.
12. Disclaimers
To the maximum extent permitted by law, the App is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement. We do not warrant that the App will be uninterrupted, error-free, or that results obtained from it will be accurate or reliable.
Nothing in these Terms excludes liability that cannot lawfully be excluded, including liability for death or personal injury caused by negligence, for fraud, or any mandatory consumer rights you have under the law of your country of residence.
13. Limitation of liability
To the maximum extent permitted by law, we will not be liable for indirect, incidental, special, consequential or punitive damages, or for loss of profits, data or goodwill, arising out of or in connection with your use of the App. Our total liability for all claims relating to the App is limited to the greater of the amount you paid us for the App in the twelve months before the claim, or ten euros (€10).
Because your data is stored only on your device, we are not responsible for its loss if you lose, reset or replace your device without a backup.
14. Indemnity
You agree to indemnify and hold us harmless from claims and costs arising out of your misuse of the App, your breach of these Terms, or your infringement of another person's rights, including through photographs you add.
15. Termination
You may stop using the App at any time by deleting it. We may suspend or terminate your access if you materially breach these Terms or if we are required to do so by law. Sections that by their nature should survive termination — including sections 10 to 14 — will survive.
16. Changes
We may modify the App or these Terms. If we make a material change to these Terms, we will update the effective date and show a notice in the App. Continuing to use the App after a change takes effect means you accept the revised Terms.
17. Governing law and disputes
These Terms are governed by the laws of Türkiye. If you are a consumer, this does not deprive you of the protection of any mandatory consumer law of your country of residence, and you may bring proceedings before the courts or consumer bodies of that country.
18. Apple-specific terms
The following applies because the App is distributed through the App Store:
- These Terms are between you and us only, not with Apple. Apple is not responsible for the App or its content.
- Apple has no obligation to provide maintenance or support for the App.
- If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
- Apple is not responsible for addressing any claim by you or a third party relating to the App, including product liability, legal or regulatory compliance, or consumer protection claims.
- Apple is not responsible for investigating, defending or resolving any third-party claim that the App infringes intellectual property rights.
- You confirm 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 on any U.S. Government list of prohibited or restricted parties.
- Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
