All rights, title and interest in the Software belong exclusively to the Company. A valid licence grants only the right of use; it does not confer ownership or any right to the source code.

Without the Company's written permission, you may not reproduce, distribute or create derivative works from our trademarks, logos or content.

7. User Account and Security

You are solely responsible for the security of your account, the confidentiality of your account information, and all transactions carried out through your account. You must notify the Company immediately upon detecting any unauthorized access.

The Company reserves the right to suspend and/or close your account without prior notice where it perceives a security threat or detects a breach of these Terms.

8. Content and Data Ownership

The log records, reports and data you generate through the Software belong to you. Sysnet may access this data only to the extent necessary and solely for the purpose of providing you with service, providing support, or fulfilling its legal obligations.

Under Law No. 5651, the retention of traffic information and the preservation of its integrity and confidentiality are your obligation in your capacity as hosting provider/access provider.

9. Fees, Invoicing and Refunds

Service fees are paid in advance in the amount specified at the time of purchase. Fees may be shown exclusive of VAT; the applicable tax legislation applies.

Due to the digital-product nature of the Software and its organization-specific licensing, the terms of refund and withdrawal are specifically regulated in the sales agreement. The exceptions under Article 15/1-(ğ) of Law No. 6502 on Consumer Protection are reserved.

10. Warranty and Disclaimer

The Software and the service are provided "as-is" and "as-available". To the maximum extent permitted by law, the Company gives no express or implied warranty as to merchantability, fitness for a particular purpose, or freedom from error.

It is not warranted that the Software will operate uninterrupted, error-free or entirely secure. It is the User's responsibility to take backup, disaster-recovery and secondary-protection measures.

11. Limitation of Liability

To the maximum extent permitted by law, Sysnet cannot be held liable for any direct or indirect loss of profit, loss of data, loss of business, reputational harm, financial loss or any similar damages and losses.

Our total liability arising from all your claims is limited to the fees you paid us in the 12-month period preceding the occurrence of the event giving rise to the claim.

This limitation does not apply in cases of intent or gross negligence.

12. Indemnification

You agree to indemnify the Company for any damages (including attorneys' fees) arising from any lawsuits, claims and administrative sanctions brought against it by third parties as a result of your conduct in breach of these Terms or of the applicable legislation.

13. Force Majeure

Where obligations cannot be fulfilled due to causes beyond the parties' reasonable control, such as natural disaster, war, epidemic, cyberattack, interruption of internet infrastructure or changes in legal regulation, the liability of the relevant party is suspended for the duration of the force majeure event.

14. Amendments to the Terms

The Company reserves the right to unilaterally amend these Terms where it deems necessary. Material changes are announced at least 15 days in advance via the website or by e-mail. Your continued use of the Software after a change means that you accept the changes.

15. Governing Law and Jurisdiction

The law of the Republic of Türkiye applies to the interpretation and application of these Terms and to the resolution of any disputes that may arise.

The İstanbul Central (Çağlayan) Courts and Enforcement Offices have exclusive jurisdiction over the resolution of any disputes that may arise. The mandatory provisions of Law No. 6502 on Consumer Protection are reserved.

16. Severability and Entry into Force

The invalidity, prohibition or unenforceability of any provision of these Terms does not affect the validity of the other provisions. An invalid provision is deemed replaced by a valid provision that achieves the closest economic purpose.

These Terms are in force as of 2026-05-25.
