The accommodation business using the Service and the users authorised on behalf of that business are subject to these terms. Starting to use the Service means that these terms have been accepted.

In the event of a conflict between this page and the Adonis SaaS Usage Agreement and Data Processing Protocol approved digitally at registration, the provisions of the signed agreement apply.

2. Description of the Service

Adonis is cloud based hotel management software covering reservations, front office, accommodation, folio, accounting, channel management, reporting and related modules. Depending on the package selected, the Service may also include additional modules such as restaurant management, identity notification integration, digital marketing and reputation management.

The Service Provider reserves the right to develop, update and modify the functions of the software. Changes that materially affect the user experience are announced in advance.

3. Accounts, Authorisation and User Responsibility

  • User accounts are specific to the property; access rights are defined on a role basis by the property administrator.
  • The property is responsible for the confidentiality of the account credentials and for the transactions carried out through the account.
  • The user may not use the Service in breach of applicable legislation, in a manner that infringes the rights of third parties, or by methods that endanger the security of the system.

4. Third Party Integrations

The user activates integrations with external services such as the channel manager, the e-invoice integrator, Law No. 5651 logging, Google Business Profile, Facebook and Instagram at their own discretion.

  • Activating these integrations means that consent has been given to the mutual sharing of the relevant data with those platforms.
  • For the Google and Meta integrations, access is limited to the authorisation granted by the property with its own account; that authorisation may be revoked at any time.
  • The terms of use and the subscription fees of external platforms are the responsibility of the user.
  • The Service Provider cannot be held liable for outages, policy changes or access restrictions occurring on external platforms.

5. Fees

Service fees are calculated on a monthly unit price per room according to the package selected. Current package contents and pricing are set out in the Market section of the application and in the sales agreement. The discount conditions defined for annual advance payments are stated in the agreement.

6. Service Continuity and Limitation of Liability

  • The Service Provider takes reasonable technical measures to provide the service without interruption; data is backed up.
  • Hardware failures, outages caused by internet infrastructure, force majeure events and disruptions arising from third party services fall outside the scope of liability.
  • The total financial liability of the Service Provider is limited to the service fees paid by the user in the last 3 months.
  • No liability is accepted for indirect damages, loss of profit or loss of business claims.

7. Data Protection

The principles governing the processing of personal data are set out on the Privacy Policy page: https://adonisotel.com/guvenlik

Retention obligations arising from legislation (KBS notifications, logs under Law No. 5651, financial records) are reserved.

9. Legal Compliance

The software provides integration support for the requirements of the Identity Notification System (KBS) and of Law No. 5651. The property is responsible for fulfilling these obligations.
