Terms of Use (EULA)
Last updated: August 11, 2026
Summary: Your data stays in Turkey. Our Platform is solely an appointment coordination tool for professionals (barbers, teachers, dentists, coaches, etc.) and their clients. The developer is not responsible for the content, quality, or professional outcomes of any services provided. No advertising or third-party tracking is used; only pseudonymized technical error logs are sent abroad.
By downloading the "Kelan" mobile application ("App") or using the associated booking website ("Website"), you agree to these Terms of Use. If you do not agree, do not use the App or Website.
In these Terms, "developer" / "Provider" refers to the natural person Öncüm Korkmaz Yılmaz operating the Platform. "Platform" refers to the App and Website collectively.
1. Definition and Purpose
The Platform is a technical infrastructure and intermediary service that enables independent professionals ("Service Providers") in various fields to plan their working schedules digitally, and allows users ("Service Recipients") seeking their services to select available time slots via booking links and submit appointment requests.
The Platform is not a medical device, accredited educational institution, or professional supervisory body; it does not provide diagnosis, treatment, training, or professional expertise advice in any field.
2. Disclaimer
- Professional Service Liability: The content, quality, accuracy, legal compliance, and any medical, physical, or financial consequences of services provided by Service Providers (teachers, dentists, coaches, barbers, etc.) outside the Platform are solely the responsibility of the Service Provider. The developer is not liable for any injury, incorrect intervention, inadequate training, or dissatisfaction arising during service delivery.
- Appointment Management: The developer is not responsible for any time or financial losses incurred by Service Recipients due to Service Providers approving, rejecting, or canceling appointments, or entering incorrect working hours.
- Cancellation policy: The free-cancellation window and the rules around it are set by the Service Provider. Kelan does not set, enforce, or impose them on either party; the Platform only records cancellations and no-shows and relays them to that Provider. Any fee, penalty, or similar claim arising from a late cancellation or a missed appointment is strictly between the Service Recipient and the Service Provider, and the developer is not a party to it.
- Financial Relationships: There is no payment infrastructure on the Platform. The developer is not a party to any disputes arising from billing or payment arrangements between users.
3. Registration Requirements
- Service Provider Registration: Service Providers register on the App via Google or Apple and are solely responsible for the security of their accounts.
- Service Recipient Verification: Service Recipients must provide their name, surname, phone number, and email address when booking, and verify the one-time code (OTP) sent to their email. Users are responsible for any false or misleading information submitted.
4. Third-Party Sign-In and App Stores
The App is distributed via the Apple App Store and Google Play Store. Apple and Google are not parties to these Terms; all technical and legal responsibility for the App belongs to the developer. The standard EULA provisions of the respective stores remain applicable.
5. Intellectual Property
The design, source code, interface, and "Kelan" trademark of the Platform belong to the developer. Users are granted only a personal, non-transferable, non-exclusive right to technical use.
6. Limitation of Liability
Subject to applicable mandatory legal provisions, the developer shall not be held liable for any indirect damages, data loss, or loss of profit arising from use of the Platform. Under Article 115 of the Turkish Code of Obligations, any pre-emptive provisions eliminating or limiting the developer's liability for gross negligence or willful misconduct are void; the liability limitations in these Terms apply within that mandatory boundary.
7. Modifications and Termination
The developer may update these Terms at any time. Updated Terms are effective from the moment they are published on the Platform. Service Providers may terminate the agreement at any time via the "Delete Account" button in the App; Service Recipients may do so by ceasing use.
8. Governing Law and Disputes
Turkish law governs these Terms. Ankara Courts and Enforcement Offices have jurisdiction over any disputes.
