These Terms of Use ("Terms") govern the use of the Vesunil appointment and service management platform (the "Platform") provided by [LEGAL ENTITY NAME] ("Dualyx"). Any business that opens an account and any user who signs in to the Platform accepts these Terms.
Version: v1 · Last updated: 4 September 2026
1. Parties and definitions
- Dualyx: [LEGAL ENTITY NAME], [ADDRESS], MERSIS: [MERSIS NUMBER]. Contact: info@dualyxlabs.com.
- Business: The natural or legal person that opens an account in its own name and uses the Platform in its commercial activity.
- User: A person who signs in to the Platform on behalf of the Business, with the role of Business Admin (
BUSINESS_ADMIN) or Provider (PROVIDER). - Customer: A third party whose appointment, payment and contact records the Business keeps on the Platform. A Customer is not a Platform user and never signs in.
- Panel: The Platform's web interface.
The Platform is a business-to-business service, not a consumer application. By opening an account, the User declares that they are authorised to represent and bind the Business.
2. Registration and verification
Registration asks for the business name, full name, email address, phone number and a password. The form includes bot protection (CAPTCHA). The Business is responsible for the accuracy and currency of the information provided.
Once registration completes, a verification link is sent to the email address. The Platform cannot be accessed until verification is complete. Acceptance of these Terms and of the KVKK Privacy Notice is recorded at registration, together with the time of acceptance and the version of the accepted text.
Keeping sign-in credentials confidential is the User's responsibility. Unauthorised access must be reported to Dualyx without delay. A User can see their open sessions in the Panel and end any of them.
3. Roles and permissions
- Business Admin: Manages the business profile, working hours, services, customers, appointments, payments, expenses, reports, messaging settings, files, users and activity records.
- Provider: Performs a limited set of tasks such as their own appointments, creating customers and recording payments.
- Platform Admin: The authorised user on the Dualyx side, who manages business records, package and feature entitlements, integration settings, storage quotas and support records.
Adding users, assigning roles and revoking access are the Business Admin's responsibility. Closing the access of people who leave the Business belongs to the Business.
4. Trial, packages and feature entitlements
Every newly opened business starts with a 14-day free trial that begins at registration and runs with the Starter package feature set.
Platform features depend on packages. Entitlements such as appointments, blocked times, recurring appointments, payments, expenses, reports, messaging, SMS, WhatsApp, multiple users and a custom logo are opened or left closed according to the Business's package. The screen of a closed feature is not hidden in the Panel; it is shown in a locked state.
When the trial or a paid package ends, the Business's data is not deleted and remains readable; only creating and changing records is blocked. The remaining period is shown in the business settings.
5. Fees
The scope, duration and price of a package are agreed separately between the parties. No online payment is taken on the Platform; the payment screens in the Panel exist to record amounts the Business collects from its own customers and are unrelated to payments made to Dualyx.
Dualyx does not process or store card data.
6. The Business's obligations
The Business is responsible for the lawfulness of the data it enters and the operations it runs on the Platform. In particular, the Business shall:
- Meet its data controller obligations under Personal Data Protection Law No. 6698 when entering personal data about its own customers. This relationship is set out in the Data Processing Agreement.
- Understand that the national identification number field on a customer record is optional, and process that data only where it is genuinely needed.
- Act in the knowledge that entering special categories of personal data (including health data) into free-text fields such as customer notes creates additional legal obligations.
- Comply with consent, İYS registration and content rules for the SMS, WhatsApp and email messages sent to customers. See the Commercial Electronic Messages and İYS document for detail.
- Be responsible for the content of, and its right to upload, any file placed on the Platform.
7. Messaging and integrations
The Platform supports notifications over SMS (İleti Merkezi, Verimor), the WhatsApp Cloud API and email. Whether these channels work depends on the relevant provider's service, rules and approvals.
SMS and WhatsApp credentials can be configured per business. They are stored encrypted and shown masked in the Panel. Provider-side balance, sending limits, template approval and number verification requirements are the Business's responsibility.
Dualyx is not responsible for delivery if a provider fails to deliver a message, delays it or restricts an account. Sending and delivery states are recorded in the Panel.
8. File upload and storage
The Business can upload business documents, a logo, profile photos and support attachments through the Panel. Each business has a storage quota (250 MB by default) and new uploads are blocked once it is full. Quota increases are performed by Dualyx.
Business documents and support attachments are stored privately; logos and profile photos are served over a stable link so that they can be displayed in the Panel.
When a customer list is bulk imported from an Excel file, the uploaded file is not stored permanently; only the imported records remain.
9. Prohibited uses
- Using the Platform unlawfully or in a way that infringes third-party rights.
- Attempting to access data without authorisation, attempting to cross tenant boundaries, or attempting to bypass security measures.
- Reverse engineering the source code, sending excessive automated requests, or disrupting the operation of the service.
- Reselling the Platform or offering it as a service to third parties without permission.
- Sending commercial electronic messages to recipients who have not consented.
10. Intellectual property
The Platform's software, interface, source code, design and brand belong to Dualyx. These Terms transfer no rights other than the right to use the Platform for the duration of the agreement.
Data the Business enters into the Platform belongs to the Business. Dualyx processes it only to provide and maintain the service and to carry out the operations the Business requests.
11. Service continuity and changes
Dualyx makes reasonable efforts to provide the service without interruption; temporary outages may occur due to maintenance, updates or causes beyond its control. Planned maintenance is announced in advance where possible.
Dualyx may improve, change or remove Platform features. Changes that significantly affect the Business's use are communicated beforehand.
12. Limitation of liability
The Platform is a business management tool; it is not legal, financial, tax or health advice. Dualyx is not responsible for the outcome of decisions taken in reliance on the data or reports in the Platform.
To the extent permitted by law, Dualyx is not liable for indirect damages, loss of profit, indirect consequences of data loss, or interruptions in third-party providers' services.
13. Suspension and termination
The Business may stop using the service at any time. Deletion of the account and its data is requested as described in the Account and Data Deletion document.
Dualyx may suspend access or terminate the agreement in the event of a serious breach of these Terms, unlawful use, conduct that threatens security, or failure to meet payment obligations. Prior notice is given where possible, along with a reasonable period to export data.
14. Support
Support requests and feedback can be submitted from the support screen in the Panel. Scope and response expectations are described in the Support document.
15. Changes to these Terms
Dualyx may update these Terms. Significant changes are communicated through the Panel and re-acceptance of the current text may be required. Every version is published at this address and carries a version number and date.
16. Governing law and jurisdiction
These Terms are governed by the laws of the Republic of Türkiye. The courts and enforcement offices of [COMPETENT COURT] have jurisdiction over disputes.
