They govern your access to and use of the Stepo mobile application and related services (together, the "Service").

By creating an account or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

1. Definitions

• "Account" means the account you create to access the Service.
• "Content" means any text, photos, videos, comments, and other material posted on or through the Service.
• "User Content" means Content that you submit, upload, or share.

2. Eligibility

You must be at least 13 years old to use the Service. If you are under the age of majority in your jurisdiction, you may use the Service only with the involvement and consent of a parent or legal guardian. For users in Vietnam, where you are a child under 16, a parent or legal guardian must consent to your use of the Service; for children aged 7 and older, the consent of both the child and the parent or guardian is required where mandated by law. By using the Service, you represent that you meet these requirements and that the information you provide is accurate.

3. Your Account

• You are responsible for maintaining the confidentiality and security of your Account and password.
• You are responsible for all activity that occurs under your Account.
• You must provide accurate information and keep it up to date.
• Notify us promptly at chaucao@chauapps.com of any unauthorized use or security breach.

4. License to Use the Service

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download and use the Service for your personal, non-commercial use. We reserve all rights not expressly granted.

5. Your Content

You retain ownership of your User Content. By posting User Content, you grant Chau Apps a non-exclusive, worldwide, royalty-free, sublicensable license to host, store, copy, reproduce, adapt (for formatting and display), publish, and display that User Content solely to operate, provide, and improve the Service. This license ends when you delete your User Content or your Account, except to the extent it has been shared with others who have not deleted it, or where retention is required by law or for backup for a limited period.

You represent and warrant that you own or have the necessary rights to your User Content and that it does not infringe the rights of any third party or violate any law.

6. Acceptable Use

You agree not to use the Service to:

• Post Content that is illegal, harmful, threatening, abusive, harassing, defamatory, hateful, or that infringes the rights of others;
• Post sexually explicit material involving minors or any content that exploits or endangers children;
• Impersonate any person or entity or misrepresent your affiliation;
• Upload viruses or malicious code, or otherwise compromise the security or integrity of the Service;
• Attempt to access accounts, systems, or data without authorization, or interfere with or disrupt the Service;
• Reverse engineer, decompile, or attempt to extract the source code of the Service, except as permitted by law;
• Scrape, harvest, or collect data about other users without authorization;
• Send spam or unsolicited communications, or engage in fraud or deceptive practices;
• Violate any applicable law or regulation, including the laws of Vietnam.

7. Content Moderation, Suspension & Termination

We may review, remove, or restrict Content, and may suspend or terminate Accounts, that violate these Terms or that we reasonably believe may harm users, third parties, the Service, or Chau Apps, or that we are required to act on by law. Where reasonable and lawful, we will provide notice. You may stop using the Service and delete your Account at any time.

8. Intellectual Property & Infringement Claims

The Service, including its software, design, text, graphics, logos, and trademarks (excluding User Content), is owned by Chau Apps and protected by intellectual property laws. These Terms do not grant you any right to use our trademarks or branding without our prior written permission. If you believe Content on the Service infringes your intellectual property rights, contact us at chaucao@chauapps.com with sufficient detail to identify the Content and your rights, and we will respond appropriately.

9. Fees & Advertising

The Service is currently provided free of charge and does not display third-party advertising. We may introduce paid features or advertising in the future. If we do, we will clearly communicate any charges before they apply and update our Privacy Policy to describe any advertising-related data practices, obtaining any consent required by law.

10. Third-Party Services & App Stores

The Service relies on third-party providers (for example, hosting, storage, content delivery, analytics, crash reporting, and push notifications). Your use may also be subject to the terms of your mobile network provider and the app store from which you obtained the app. We are not responsible for third-party services we do not control.

11. Apple App Store — Additional Terms

If you download the app from the Apple App Store, the following additional terms apply:

• These Terms are between you and Chau Apps only, not with Apple Inc. ("Apple"). Apple is not responsible for the app or its content.
• Apple has no obligation to provide maintenance or support for the app.
• To the maximum extent permitted by law, Apple has no warranty obligation; any claims relating to the app's failure to conform to a warranty are our responsibility.
• Apple is not responsible for addressing product claims, including product liability, legal/regulatory compliance, or consumer protection claims.
• In the event of a third-party intellectual property infringement claim relating to the app, we, not Apple, are responsible for its investigation and resolution.
• You represent that you are not located in a country subject to a U.S. Government embargo and are not on any U.S. Government restricted-parties list.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

12. Disclaimers

To the maximum extent permitted by law, the Service is provided "as is" and "as available" without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, timely, secure, or error-free, or that Content will be accurate or reliable.

13. Limitation of Liability

To the maximum extent permitted by applicable law, Chau Apps and its directors, employees, and partners will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, data, goodwill, or other intangible losses, arising out of or relating to your use of (or inability to use) the Service. Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited.

14. Indemnification

You agree to indemnify and hold harmless Chau Apps from any claims, damages, losses, and expenses (including reasonable legal fees) arising out of your User Content, your use of the Service, or your violation of these Terms or applicable law.

15. Changes to the Service & Terms

We may modify, suspend, or discontinue all or part of the Service at any time. We may also update these Terms from time to time; we will revise the "Last updated" date above and, where changes are material, provide additional notice within the Service. Your continued use after changes take effect constitutes acceptance of the updated Terms.

16. Governing Law, Language & Disputes

These Terms are governed by the laws of Vietnam, without regard to conflict-of-law principles. Any dispute arising out of or relating to these Terms or the Service that cannot be resolved amicably shall be submitted to the competent courts of Ho Chi Minh City, Vietnam. These Terms may be provided in English and Vietnamese; in the event of any inconsistency, the Vietnamese version prevails for users in Vietnam to the extent required by law.

17. General

• Force majeure — we are not liable for failure or delay caused by events beyond our reasonable control.
• Severability — if any provision is held invalid, the remaining provisions remain in effect.
• No waiver — our failure to enforce a provision is not a waiver of it.
• Assignment — you may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets.
• Entire agreement — these Terms and the Privacy Policy constitute the entire agreement between you and us regarding the Service.
