Terms of service

These Terms of service (the “Terms”) are an agreement between CTA Solution Co., Ltd. (“CTA Solution”, “we”) and the individual or organization (“you”) visiting ctas.vn or using products of the CTAS ecosystem, including CTAS Work in the mobile app, at work.ctas.vn and related services (together, the “Service”).

By creating an account, choosing “I agree” or continuing to use the Service, you confirm that you have read, understood and accepted these Terms and our Privacy policy. If you do not agree, please stop using the Service.

1. Definitions

• CTAS account: the personal account used to sign in to every CTAS product at account.ctas.vn.
• Organization: a company, household business or unit created in the Service, with one or more administrators.
• Member: a user invited or activated into an Organization (staff, team lead, manager, administrator).
• Customer data: all data the Organization and its Members put into the Service, including attendance, schedules, requests, payroll and staff records.
• Plan: a paid plan (Starter, Growth, Business, Enterprise) with the limits and features published on the pricing page. Trial: 7 days of the Growth plan at no charge for a new Organization.

2. Scope

These Terms apply to every user of the Service. Some products or contracts with business customers may carry additional terms; where they conflict, the additional terms or signed contract prevail for the matters they cover.

3. Accounts

• You are responsible for all activity under your account. If you notice unauthorised access, change your password and tell us immediately.
• The person who creates an Organization is its first administrator and is responsible for inviting, permissioning and managing Members. Every Organization always has at least one administrator.

4. Your rights and obligations

4.1. Your rights

• Receive technical support at your Plan’s support level and be told about material changes to the Service and these Terms.
• Request deletion of your personal account under the Privacy policy.

4.2. Your obligations

• Comply with Vietnamese law — in particular labour, social insurance, tax and personal data protection law — when using the Service to manage employees.
• For Organizations: inform employees and have a lawful basis (including consent where the law requires it) before putting their personal data into the Service, as set out in the Data processing agreement.
• Check attendance, payroll, tax and insurance results before paying or filing them. The Service is a calculation tool that follows the configuration you set.
• Pay the fees of any paid Plan in full and on time.

5. Prohibited conduct

• Breaking the law or infringing others’ rights, legitimate interests or privacy.
• Impersonating people or organizations, giving false information, clocking in for someone else or falsifying attendance data.
• Collecting or exploiting other people’s personal data unlawfully.
• Interfering with the system, scanning for vulnerabilities, overloading, reverse engineering, copying or exploiting the Service without permission; spreading malware or spam.
• Reselling, renting or providing the Service to third parties without a written agreement with CTA Solution.

6. CTA Solution’s rights and obligations

• Provide the Service under your Plan, maintain and improve it, and protect Customer data under the Privacy policy and Data processing agreement.
• Maintain and update the Service under the Maintenance & support policy, giving reasonable notice of changes with significant impact.
• Suspend or terminate accounts that breach these Terms, show signs of fraud or harm the system, or when required by a competent authority.

7. Customer data

The Organization owns its Customer data. CTA Solution claims no ownership and processes Customer data only to provide, secure, support and improve the Service, or where the law requires. You grant CTA Solution the right to store, back up, process and display Customer data to the extent needed for those purposes.

8. Intellectual property

The software, source code, interface, the “CTAS” trademark, logos, documentation and content created by CTA Solution belong to CTA Solution or its licensors. You receive a limited, non-exclusive, non-transferable right to use the Service while your use is valid. You may not use CTAS trademarks or logos commercially without written consent.

9. Fees and payment

• Plan prices are published on the pricing page and shown at the time of purchase. Prices may change from time to time; changes do not affect time already bought.
• Plans are prepaid for a fixed term and never renew: each purchase adds time to the Organization; buying more, changing plans and converting time follow the Payment policy.
• Payment methods and invoices are covered by the Payment policy; cancellations and refunds by the Cancellation & refund policy.
• There is no free plan. After the 7-day trial, or when a Plan expires without renewal, the Organization must buy a plan to keep using the Service; data is kept for the plan’s retention period and under the Privacy policy.
• Purchased plans are not refundable under any circumstances; please use the trial before buying.

10. Third-party services

The Service may connect to third-party services such as the App Store, Google Play, the PayOS payment gateway, map services, Zalo, email and push notification services. Their use is also subject to the third party’s terms. Apple and Google are not parties to these Terms.

11. Disclaimer

To the extent permitted by law, the Service is provided as is and as available. CTA Solution works to keep the Service stable and accurate but does not guarantee it will never be interrupted or error-free, especially where the cause lies with devices, networks, operating systems or third parties.

12. Limitation of liability

• CTA Solution is not liable for indirect, incidental or consequential loss (lost profit, business interruption…) arising from use of the Service, to the extent permitted by law.
• CTA Solution’s total liability, if any, will not exceed the amount you paid for the Service in the 3 months before the event giving rise to it, unless the law requires otherwise.
• Nothing here excludes liability that the law does not allow to be excluded.

13. Suspension and termination

You may stop using the Service and request deletion of your account at any time. CTA Solution may suspend or terminate accounts that breach these Terms. On termination your right to use the Service ends; data is handled under the Privacy policy and Data processing agreement; outstanding payment obligations survive.

14. Changes to these Terms

We may update these Terms to reflect changes in the Service or the law. New versions are posted on this page with an effective date; for material changes we notify you in the app or by email. Continuing to use the Service after the effective date means you accept the updated Terms.

15. Governing law and disputes

These Terms are governed by Vietnamese law. Disputes are first resolved by negotiation within 30 days of one party’s notice. Failing that, they go to the competent People’s Court in Ho Chi Minh City. The Vietnamese version of these Terms prevails in case of any difference.
