Terms of Use, From Start to Finish.

Effective date: 5 October 2026. Version: 1.4.

1.1. This Agreement is concluded between Mustafa Eren KOÇ, the owner and operator of the Klaris mobile app (the "App" or "Klaris"), acting as a natural person ("Klaris", "we", "us" or "our"), and the natural person who downloads the App, creates an account or uses the App (the "User", "you" or "your").

1.2. Klaris is operated by an individual entrepreneur (natural person), not within a company, commercial partnership or legal entity. This forms the basis of all legal relationships concerning the App.

1.3. Beginning to use the App means that you acknowledge that this Agreement and the Privacy Policy, Privacy Notice and other policies it references constitute a valid contract concluded electronically. This Agreement is valid and binding under the relevant legislation, particularly the Turkish Code of Obligations No. 6098 and the Law on Consumer Protection No. 6502.

1.4. If you use the App on another person's behalf or for their benefit, you represent and undertake that you have authority to accept this Agreement and bind that person.

2.1. Klaris is a premium cosmetic decision-support app for the Turkish market. By scanning or manually entering the barcode of cosmetic products, the App compares product ingredients (ingredient list / INCI) with a scientific ingredient database to provide the User with an informative compatibility assessment.

2.2. The general Klaris Score, "Why This Score" and Turkish ingredient cards are free. "My Skin Match", "My Hair Match" and "Caution Notes for Your Profile", based on the skin or hair profile the User creates, are included in Klaris Premium (Article 19). These assessments are for information only and aim to support your cosmetic choices.

2.3. The App may include the following main features:

• (a) Account and Authentication: account creation and session management through Sign in with Apple on iOS and Sign in with Google on Android.
• (b) Skin/Hair Profile (Onboarding): a profile for personalisation in which the User enters information about their skin and hair characteristics.
• (c) Barcode Scanning and Product Passport: scanning products and presenting ingredient analysis.
• (d) Optional Selfie and Skin Diary: an entirely optional, skippable monthly selfie and skin diary feature for the User's own cosmetic tracking.
• (e) Product Contributions: the User suggests new products or missing information through the "Add / Complete Product" function; suggestions undergo administrator review and may or may not be published.
• (f) Community and "Skin Twin / Hair Twin": a shared feed and community content for users with the same Skin or Hair Identity; the User may participate with their chosen Community display name, a system name containing no personal information if they have not yet chosen a name, or completely anonymously. The real name and email received from the sign-in provider (Apple on iOS, Google on Android) are not displayed in the Community.
• (g) Klaris Premium: an optional, automatically renewing subscription. It unlocks personalised compatibility commentary and related additional features beyond the free offering. Details are in Article 19.

2.4. Klaris reserves the right to change, suspend or discontinue the App's features, content, functionality or any part of it at any time without prior notice. Klaris does not undertake to provide continuous availability of any particular feature.

2.5. Using the App requires a compatible device, operating system version and internet connection. Meeting these requirements and all associated costs (including data/internet charges) are the User's responsibility. On Android, the App's server-connected features (including product scanning, accounts and Klaris Premium) are available only on devices with Google Play services that pass Google Play's device verification.

3.1. Klaris is available to users of all ages. Users who are minors (under 18) are expected to use the App with the knowledge and supervision of a parent or guardian. By using the App, you declare that you have the legal capacity required to conclude this Agreement or have parental/guardian consent.

3.2. If we discover that a minor is using the App without parental/guardian consent, we reserve the right to suspend or terminate the account and delete the associated data in accordance with the relevant legislation.

4.1. To use certain App features, you must create an account through Sign in with Apple on iOS or Sign in with Google on Android. You agree to provide accurate, current and complete information when creating your account.

4.2. You are solely responsible for the confidentiality and security of your account and associated authentication details. As the User, you are held responsible for all actions carried out through your account.

4.3. If you become aware of unauthorised use of your account or a breach of its security, you agree to notify us without delay via kvkk@klaris.com.tr.

4.4. A person may create only one account. Creating multiple accounts, impersonating another person, using false identity information, or transferring, selling or renting your account to another person is prohibited. The following exception applies: accounts created through Sign in with Apple on iOS and Sign in with Google on Android are separate Klaris accounts; they are not linked, and Premium and data do not transfer between them. A person who uses Klaris on both platforms and therefore has two separate accounts does not violate the single-account rule.

4.5. Klaris reserves the right, on reasonable grounds, to verify, suspend or close any account where fraud, abuse, a security risk or a breach of this Agreement is suspected.

5.1. You agree to use the App only for lawful purposes and in accordance with this Agreement. The following conduct is expressly prohibited, and each instance constitutes a material breach of this Agreement:

• (a) In whole or in part, scraping, copying, bulk extracting, indexing, accumulating or reproducing the App's ingredient database, Klaris Score, scoring logic, analyses, content or images.
• (b) Accessing the App or its infrastructure using automated tools (bots, robots, spiders, crawlers, scrapers, automated scripts, etc.) or collecting data using them.
• (c) Performing reverse engineering, decompilation or disassembly of, or attempting to create derivative works from, the App's software, algorithms, scoring method or database structure (except to the extent permitted by applicable mandatory law).
• (d) Using databases, scoring, analyses or content obtained from the App to create, develop or train a product, service or database that competes with or is a rival to Klaris (including training artificial intelligence/machine learning models).
• (e) Bypassing, disabling or evading the App's security measures, access restrictions, usage quotas or rate limits.
• (f) Introducing viruses, malware or other harmful code into the App; placing an excessive or disproportionate load on the App's infrastructure; or attempting to cause service disruption.
• (g) Impersonating another user, providing misleading information, or sharing content involving harassment, threats, insults, hate speech, discrimination or obscenity, or infringing third-party rights (including intellectual property, personality rights and privacy).
• (h) Conducting unlawful, misleading, deceptive or unauthorised commercial/advertising activities (including spam) through the App.
• (i) Reproducing, distributing, making publicly available, renting, selling, sublicensing or otherwise exploiting the App's source code, content or any part of it without Klaris's written permission.
• (j) Providing or selling App output to third parties for medical diagnosis, treatment, prescribing or a similar professional purpose.

5.2. In the event of a violation of these prohibitions, Klaris reserves the right to remove the relevant content, restrict access, suspend or terminate the account and pursue legal remedies without notice.

6.1. Klaris is NOT a medical app. The App is provided solely for information and cosmetic compatibility purposes. No assessment, Klaris Score, analysis, commentary, suggestion or content in the App constitutes medical advice, diagnosis, treatment, a prescription or healthcare, and none may be interpreted as such.

6.2. Klaris does NOT replace a doctor, dermatologist or healthcare professional. The App does not replace, and is not an alternative to, a medical examination, dermatological consultation or professional health assessment.

6.3. If you have any concern, uncertainty, allergy, sensitivity, skin condition or symptom relating to your skin, hair or general health, always consult a qualified doctor or dermatologist before using, changing or discontinuing a cosmetic product. Do not delay or disregard professional medical advice because of an assessment provided by the App.

6.4. A cosmetic product appearing "compatible" does not guarantee that it will not cause an allergic reaction, irritation or another adverse effect for you. Skin and hair responses vary from person to person. Before using a new product, you are advised to follow the manufacturer's instructions and, if necessary, perform a patch test.

6.5. No guarantee of accuracy or outcomes. Klaris gives no guarantee as to the accuracy, currency, completeness or fitness for a particular purpose of ingredient information, product formulations, scores or analyses in the database. Manufacturers may change product formulations; current information on the packaging should always take precedence. App output is automated information, not a professional opinion.

6.6. In a medical emergency, please call the 112 Emergency Call Centre immediately or go to the nearest healthcare facility. The App is not designed for emergencies.

7.1. Intellectual and industrial property rights in the App, its content and all its components belong exclusively to the individual founder Mustafa Eren KOÇ. These include, without limitation:

• (a) Cosmetic Ingredient Database: its content, structure, selection, arrangement and compilation.
• (b) Klaris Score: scoring logic, algorithms, weightings, matching methods and all analyses and commentary texts.
• (c) The corpus of product images, visual arrangements and graphics.
• (d) Klaris Brand: its name, logo, trade dress, design language, interface design, feature names such as "Skin Twin / Hair Twin" and other distinctive signs.
• (e) The App's software, source code, interfaces, data models and all associated copyright and other rights.

7.2. This ingredient database, scoring system and analyses are the founder's protected and highly valuable intellectual property, resulting from labour and investment. They are protected under Law No. 5846 on Intellectual and Artistic Works, Industrial Property Law No. 6769, the unfair competition provisions of the Turkish Commercial Code No. 6102 and all relevant legislation.

7.3. Limited licence. Subject to your compliance with this Agreement, Klaris grants you a limited right to use the App solely for personal, non-commercial purposes under a non-exclusive, non-transferable, non-sublicensable and revocable licence. This Agreement does not transfer any ownership right in the App to you; all rights are reserved by Klaris.

7.4. All rights not expressly granted in this Agreement are reserved by Klaris. You may not use Klaris's brand, logo or other distinctive signs without prior written permission.

8.1. Scope. This Article covers product contributions through the "Add / Complete Product" function, community posts, content within "Skin Twin / Hair Twin" and any content you upload, submit or share in the App ("User Content"). Processing of your optional selfie and skin diary data is also governed by the Privacy Policy and Privacy Notice.

8.2. Licence. By submitting User Content, you grant Klaris a worldwide, royalty-free, non-exclusive, sublicensable and transferable licence to use, reproduce, process, adapt, edit, publish, display and distribute that content for the purposes of providing, operating, developing, monitoring and promoting the App and its services. This licence ends to a reasonable extent when you remove your content from the App, except for copies Klaris holds in backups and records that must be retained to meet legal obligations.

8.3. Your representations and undertakings. For each item of User Content you submit, you represent and undertake that: (a) you are legally entitled to share that content and grant the licence above; (b) the content does not infringe third-party intellectual property, personality or privacy rights; and (c) the content is accurate, lawful, not misleading and compliant with this Agreement.

8.4. Moderation and no obligation to publish. All product contributions and other User Content we consider appropriate are subject to administrator review and moderation. Klaris has no obligation to publish, use or keep any User Content published. At its discretion, Klaris reserves the right to reject, edit, shorten, remove or unpublish any User Content without giving a reason or prior notice.

8.5. Rights in published contributions. When a product contribution is published, it becomes integrated into the App's knowledge base; the relevant edited data and their presentation within the App fall within Klaris's intellectual property. This does not affect your representations under Article 8.3 or the fact that you may not claim any fee for the contribution. No fee, royalty or other payment is made to you for User Content.

8.6. Responsibility rests with the User. Only the User who submits User Content is responsible for it. Klaris does not endorse, verify or warrant User Content and cannot be held liable for damage arising from it.

8.7. Product contributions after account deletion. When you delete your account, the product photos and product information (brand, product name, barcode, category) you added through the "Add / Complete Product" process, whether published or not, are product data that do not identify you and may therefore continue to be retained with their link to you removed (anonymised) to maintain and improve the product database's accuracy. In contrast, the personal free-text notes and personal images (selfies / skin diary) you added to your contributions are deleted/destroyed. This Article is read together with the retention and deletion principles in the Privacy Policy. Limited records remaining after deletion (encrypted backups and, if you choose it on Android, a subscription recovery record) and their retention periods are set out on the account deletion page.

9.1. Community features and "Skin Twin / Hair Twin" feeds are provided so that users can share experiences in a common feed with other users who have the same Skin or Hair Identity. You may participate in these features with your chosen Community display name, a system name containing no personal information if you have not yet chosen a name, or completely anonymously; the choice of participation is yours. The author name used when a post is published is retained on that post; later changes to your display name do not retrospectively change author names on earlier posts. Your real name and email received from the sign-in provider (Apple on iOS, Google on Android) are not displayed in the Community.

9.2. You agree to act respectfully, honestly and lawfully in the Community. In addition to the prohibited conduct in Article 5, harassment or unwanted contact with other users, unauthorised disclosure of their personal data, directing them for commercial purposes or making statements constituting medical advice is prohibited.

9.3. Experiences shared within the Community are personal and do not constitute generally applicable advice, a professional opinion or a medical recommendation. You alone are responsible for decisions you make based on another user's post.

9.4. Klaris reserves the right to moderate content, issue warnings, remove content and restrict the community access or accounts of users who violate the rules in order to maintain community order.

10.1. The App is provided on an "AS IS" and "AS AVAILABLE" basis. To the maximum extent permitted by applicable law, Klaris gives no express or implied warranty. This includes, without limitation, disclaiming implied warranties of merchantability, fitness for a particular purpose, uninterrupted operation, freedom from errors, accuracy, currency, security or non-infringement of third-party rights.

10.2. Klaris does not warrant that the App will operate without interruption, on time, securely or without errors; that results will be accurate, reliable or complete; or that identified errors will be corrected.

10.3. You use the App entirely at your own choice and risk. No information or advice obtained from the App creates any warranty unless expressly stated in this Agreement.

11.1. To the maximum extent permitted by applicable law, Klaris (and its manager/representatives) is not liable for indirect, incidental, special, punitive or consequential damage arising from use of or inability to use the App (including loss of profit, data, business or reputation, non-pecuniary damage or damage relating to health/cosmetic outcomes) in any circumstances.

11.2. In particular and without limitation, Klaris cannot be held liable for damage arising from: (a) any effect on skin/hair/health resulting from using, not using or changing a cosmetic product; (b) any error, omission or outdated information in a database, score or analysis; (c) User Content or other users' conduct; (d) unauthorised use of your account; or (e) third-party services (including Apple and Google).

11.3. Subject to cases required by applicable law, Klaris's total liability for any claim connected with this Agreement or the App shall in no event exceed: (a) the amount you actually paid Klaris for the App in the twelve (12) months preceding the event giving rise to the claim; or (b) fifty (50) Turkish Lira if no such payment was made.

11.4. Nothing in this Article limits or excludes Klaris's liability arising from intent or gross negligence, liability for death or bodily harm, or other liability that cannot be limited or excluded under applicable mandatory law. Some legal systems may not permit limitations of liability for certain damage. If applicable mandatory law prevents some of the limitations in this Article from applying, those limitations apply only to the maximum extent permitted; the remaining provisions remain valid. This Agreement does not remove or limit consumers' mandatory rights under consumer legislation.

12.1. You agree to indemnify, defend and hold Klaris (and its manager/representatives) harmless from any claims, actions, damage, losses, liabilities, costs and expenses (including reasonable legal fees) arising from or connected with:

• (a) Your use of the App contrary to this Agreement or applicable legislation.
• (b) Your breach of any provision of this Agreement.
• (c) User Content you submit or its infringement of third-party rights.
• (d) Your interpretation of App output as medical advice or presentation of it as such to third parties.
• (e) Your infringement of third-party rights (including intellectual property, personality rights and personal data).

12.2. Klaris reserves the right, at its discretion, to assume the defence and control of any claim covered by the indemnity; in that event, you agree to cooperate with Klaris in defending the claim. This Article may not be interpreted to remove consumers' mandatory rights under consumer legislation.

13.1. The App uses third-party services such as sign-in providers (Sign in with Apple on iOS, Sign in with Google on Android), push notifications, in-store subscriptions, device integrity verification (App Attest on iOS, Google Play Integrity on Android) and the barcode scanning library on Android. Use of these services is also subject to the relevant third parties' (Apple Inc. and Google LLC) own terms and policies.

13.2. Klaris mobile app users' app data are stored in Türkiye, on servers in Türkiye. Only for the secure management of App sign-in, delivery of push notifications, and verification of device integrity and subscriptions may your limited technical identifiers (device token, Apple ID or Google account identifier, device-verification record) be transferred to secure servers abroad through Apple Inc. and Google LLC infrastructure. The device identifier and notification title and short text are transmitted through push notification infrastructure; your name, cosmetic ingredient formulas or other personal data are not included in the notification content. The scope and legal basis of these transfers (including, for the sign-in provider, the exception under KVKK Article 9 for transfers necessary to perform a contract initiated by the data subject) are explained in detail in the Privacy Notice and Privacy Policy. Klaris is not responsible for third parties' acts or omissions arising from their own systems.

13.3. klaris.com.tr is served through Cloudflare's global Pages infrastructure. In the separate web newsletter process, email and consent records may also be processed outside Türkiye in Workers KV. Newsletter registration and delivery are open. Web consent covers only up to two informative newsletters per month; it is separate from other in-app permissions. Unsubscribe requests are received at info@klaris.com.tr. Details are in the Newsletter Privacy Notice.

14.1. Your personal data are processed in accordance with Law No. 6698 on the Protection of Personal Data ("KVKK") and relevant legislation. The data controller is the individual founder, Mustafa Eren KOÇ. Mobile app users' app data are stored in Türkiye, on servers in Türkiye.

14.2. The purposes and legal grounds for processing your data (including performance of a contract under Article 5/2-c and explicit consent under Article 5/1 for optional selfies and notifications), possible recipients, retention periods and your rights under KVKK Article 11 are explained in detail in the Privacy Notice and Privacy Policy, accessible within the App. Accepting this Agreement confirms that you have read those documents.

14.3. For requests concerning the processing of your data and applications under the KVKK, you may contact kvkk@klaris.com.tr. You can also delete your account using the in-app "delete account" function. As stated in the Privacy Notice and Privacy Policy, deletion requests are fulfilled within thirty (30) days at the latest.

15.1. Klaris reserves the right to suspend or terminate your account or access to the App in the event of a breach of this Agreement or applicable law, a security risk, suspected fraud or a need to protect the App's integrity. For material breaches, this may occur without prior notice; in other cases, reasonable efforts are made to provide advance information where possible.

15.2. You may terminate your account at any time using the in-app "delete account" function or by contacting kvkk@klaris.com.tr. Terminating your account also terminates this Agreement; a subscription purchased through a store continues unless separately cancelled through that store under Article 19.6.

15.3. On termination of this Agreement, your right to use the App ends immediately. Provisions that by their nature should survive termination, including intellectual property (Article 7), content licence (Article 8), disclaimer of warranties (Article 10), limitation of liability (Article 11), indemnity (Article 12) and governing law (Article 17), remain in force.

15.4. After your account is terminated, your personal data are processed, retained or deleted according to the principles in the Privacy Notice and Privacy Policy.

16.1. Klaris reserves the right to update or amend this Agreement at any time. Material changes are communicated by reasonable means (through an in-app notification or an update to the effective date).

16.2. Continuing to use the App after changes take effect means you accept the updated Agreement. If you do not accept the updated Agreement, you must stop using the App and delete your account. If a material change significantly affects your rights, you have the right to reject it and terminate your account before continuing to use the App.

17.1. This Agreement is governed by and interpreted in accordance with the law of the Republic of Türkiye.

17.2. Jurisdiction to resolve any dispute arising from or connected with this Agreement lies with the Istanbul (Çağlayan) Courts and Enforcement Offices. However, for Users who are consumers, mandatory jurisdiction rules under consumer legislation are reserved; depending on the applicable monetary thresholds, consumer Users have the right to apply to Consumer Arbitration Committees or Consumer Courts at their place of residence or where the transaction took place, and this Agreement does not restrict that right.

18.1. Severability. If any provision of this Agreement is considered invalid or unenforceable, the validity of the other provisions is unaffected; the invalid provision is deemed replaced by a valid provision closest to its purpose.

18.2. Limited waiver. Klaris's failure or delay in exercising any right under this Agreement does not constitute a waiver of that right.

18.3. Assignment. You may not transfer your rights and obligations under this Agreement without Klaris's prior written permission. Klaris may assign this Agreement to third parties; such an assignment may not reduce consumer Users' rights under this Agreement.

18.4. Entire agreement. This Agreement, together with the Privacy Notice, Privacy Policy and other policies referenced within the App, constitutes the entire agreement between the parties.

18.5. Contact. For questions and notices concerning this Agreement or the App, you may contact kvkk@klaris.com.tr. Website: klaris.com.tr.

19.1. Free offering. The App's basic functions are free: barcode scanning, product passport, Klaris Score and ingredient list are available to every User who creates an account. The subscription below does not narrow this offering.

19.2. Subject of the subscription. Klaris Premium is an optional, automatically renewing subscription service that unlocks personalised compatibility commentary and related additional features beyond the free offering.

19.3. Duration and price. Subscriptions are offered weekly, monthly or annually. Current durations and prices are displayed on the purchase screen before the purchase. Charges are collected not by Klaris but by the store from which you downloaded the App: the App Store on iOS and Google Play on Android.

19.4. Automatic renewal. Unless cancelled at least twenty-four (24) hours before the end of the current period, the subscription renews automatically and the charge is applied to the payment method linked to your store account (your Apple ID on iOS, your Google account on Android). On Android, renewal and calculation of the final cancellation time are subject to Google Play's own rules. The renewal fee is collected at the beginning of the period in which renewal occurs.

19.5. Cancellation. You may cancel your subscription at any time. Cancellation is through the store, not Klaris: on iOS, through Settings > Apple ID > Subscriptions on your device; on Android, through Google Play's subscriptions section. The subscription management link in the App takes you directly to the relevant store page. Klaris has no access to these settings. Cancellation takes effect after the current billing period ends; your Premium access continues throughout that period.

19.6. Account deletion does not end a subscription. Deleting your Klaris account does not automatically cancel your store subscription (Apple on iOS, Google Play on Android). To stop charges, you must separately cancel the subscription through the route above.

19.7. Refunds. Since purchases are made through the store, refund requests are subject to the store's refund policy. On iOS, refund requests are directed to Apple; Klaris has no authority to refund App Store purchases directly. On Android, Google Play's refund policy is reserved; refund requests sent to Klaris are also assessed in accordance with the law.

19.8. Price changes. Subscription prices may change. If the price of an existing subscription increases, the store informs you before the change takes effect. On iOS, the subscription does not renew if you do not approve the increase. On Android, Google Play notifies you of an increase at least 30 days in advance. If the increase requires your approval and you do not approve it, the subscription ends at the end of the current period. For an increase that does not require approval under Google Play rules, you may cancel your subscription through Google Play before the new price applies; if you do not cancel, the subscription continues at the new price.

19.9. Trial period. If a trial period is offered, its duration and conditions are stated on the purchase screen. Unless cancelled during the trial, the subscription continues on a paid basis.

19.10. Changes to features. Article 2.4 is reserved: Klaris may change features. However, if Premium's main benefit is materially reduced during a paid period, the User is informed.

19.11. Cross-platform validity. A Premium subscription is valid for the Klaris account on the platform of the store where it was purchased: an App Store subscription is used with your Sign in with Apple account on iOS; a Google Play subscription is used with your Sign in with Google account on Android. It does not transfer to the account on the other platform (Article 4.4).
