When using Doopi, you must not:

• Use the service to spread malware, spam or scams.
• Try to gain unauthorized access to systems, accounts or other people's data.
• Interfere with, overload or probe the service for vulnerabilities without permission.
• Copy, resell or commercially exploit the service without our written consent.

5.Plans and payment

Doopi currently offers a Free plan with some limits on the number of decks and cards. We do not take payments inside the app yet.

When paid plans become available, prices, benefits, billing cycles and the refund policy will be clearly shown before you buy.

6.Intellectual property

The Doopi name, logo, interface, source code and documentation belong to the Doopi team and are protected by law. These terms do not give you any ownership of the service beyond the right to use it as described here.

7.Suspension and termination

You can stop using the service and ask us to delete your account at any time.

We may suspend or terminate accounts that violate these terms or harm other users or the system. Where possible, we will tell you why and give you a chance to respond.

8.Disclaimer of warranties

The service is provided "as is". We work to keep Doopi stable and secure, but we do not guarantee that it will always be uninterrupted, error-free or fit for every particular purpose. Please keep your own backups of important content.

9.Limitation of liability

To the extent permitted by law, the Doopi team is not liable for indirect, incidental or consequential damages arising from the use of, or inability to use, the service, including data loss or interrupted study.

10.Changes to these terms

We may update these terms as the service changes. The date of the latest update is always shown at the top of the page; for significant changes we will notify you in the app or by email before they take effect. Continuing to use the service after the effective date means you accept the new terms.

11.Governing law

These terms are governed by the laws of Vietnam. Any dispute will first be resolved through negotiation; if that fails, it will be brought before the competent authorities in Vietnam.
