Effective date: August 7, 2026
Last updated: August 9, 2026

Thank you for using Mestrio Studio, Android package name com.mestrio.studio (the “App”). These Terms of Service (the “Terms”) are an agreement between you and the individual developer/operator, Robin Wang (“we,” “us,” or “our”), governing your download, installation, and use of the App. Please read them carefully before using the App.

Privacy Policy URL: https://mestrio-studio.web.app/privacy/

By accepting, downloading, installing, launching, or using the App, you confirm that you have read, understood, and agree to these Terms and the Mestrio Studio Privacy Policy. If you do not agree, do not use the App.

1. The App and Its Nature

The App is a locally operated tool for live-production, preview, recording, streaming, and media-scene editing. Features may include audio/video capture, screen capture, scene composition, external-device connection, network media and browser sources, project import/export, platform authorization, streaming to servers you configure, and local file handling.

The current version does not operate an App account system, cloud project hosting, cloud content backup, live-content distribution service, or project-data relay. Your projects and content are processed and stored only on your device or in a location you choose and are not uploaded to an App server. Some third-party account connections may use a minimal, stateless authorization relay to exchange, refresh, or revoke OAuth credentials when the provider requires a confidential client. You choose and manage the third-party platforms, streaming servers, URLs, network-media addresses, and storage locations that you use. Live content is sent directly from your device to the applicable third-party service.

We may issue updates and patches, change features, impose limits, or discontinue features. Except where applicable law requires otherwise, we do not guarantee that a particular feature will remain available or be compatible with every device, system version, network, external device, or third-party service.

2. Eligibility and Accounts

You must have the legal capacity required to enter into these Terms. If you are a minor, use the App with the consent and guidance of a parent or guardian. You are responsible for ensuring that your use of the App, your recordings and streams, and your third-party accounts comply with the laws that apply to you and the relevant service rules.

The App currently does not require an account with us. If you connect a third-party streaming platform, account service, or other third-party service, that account is independently managed by its provider. You are responsible for maintaining account credentials, multi-factor authentication, authorization scopes, and streaming permissions, and for actions taken through that account.

3. License to Use the App

Subject to your compliance with these Terms, applicable law, and app-store rules, we grant you a limited, revocable, non-exclusive, non-transferable, and non-sublicensable license to download, install, and use the App on compatible devices that you lawfully control.

Unless applicable law expressly permits it or we give prior written consent, you may not:

The App and its interface, code, design, trademarks, documentation, and all content not supplied by you are owned by us or the applicable rights holders. These Terms do not transfer ownership to you.

4. Your Content and Responsibilities

“Your Content” means audio, video, images, screen content, text, scenes, projects, media, URLs, stream information, and related data that you create, import, capture, record, edit, stream, export, or share through the App.

You retain the rights you lawfully have in Your Content. You authorize the App only to preview, process, save, export, transmit, or deliver Your Content on your device as you instruct. We do not receive, upload, retain, or otherwise use Your Content. When you actively stream or use another Third-Party Service, content goes directly from your device to the service you select.

You represent and warrant that:

  1. you own or have obtained all rights, permissions, and consents needed to process, record, upload, distribute, publicly display, and stream Your Content;
  2. you have obtained required consent from people who are filmed, recorded, screen-shared, or otherwise included in Your Content, and have provided legally required privacy notices;
  3. Your Content and use do not infringe copyright, neighboring rights, portrait/publicity rights, privacy, reputation, trademark, trade secret, or any other rights;
  4. you will not use the App to create, store, distribute, or stream unlawful, harmful, fraudulent, insulting, defamatory, privacy-invasive, child-exploitative, or otherwise improper content; and
  5. you will comply with all laws and platform rules that apply to you, including rules concerning streaming, publishing, advertising, privacy, data protection, copyright, music licensing, employment, and tax.

You are responsible for reviewing, backing up, removing, and handling complaints about content that you send to a third-party server or platform. We do not pre-screen Your Content and are not responsible for its legality, accuracy, completeness, or availability.

5. Third-Party Services, Devices, and Links

The App may enable you to connect to or use third-party services and devices, including streaming platforms, account-authorization services, app-store or payment services, browser sources, network-media sources, local-network services, model-download URLs, external capture devices, and other network or hardware services (collectively, “Third-Party Services”).

Third-Party Services are not controlled or endorsed by us. Any agreement, payment, authorization, data transfer, content publication, outage, dispute, or loss between you and a third party is between you and that third party and is governed by its terms and policies. We do not guarantee that any Third-Party Service is continuously available, secure, error-free, lawful, compatible, or suitable for your purposes.

You expressly authorize the App to connect directly from your device to Third-Party Services or devices in accordance with your settings. Before connecting, verify the domain, server address, stream key, authorization scopes, and network environment. You are responsible for consequences caused by an incorrect address, exposed key, unauthorized device access, or third-party changes.

6. Purchases, Subscriptions, and Refunds

If the App offers subscriptions, one-time purchases, or other digital items through a third-party app store or payment service, prices, taxes, billing, payment, auto-renewal, cancellation, refunds, and disputes are governed by that service’s rules, order screen, and applicable law presented at the time of purchase.

A subscription may automatically renew at the end of the current period unless you cancel it through the applicable service account under that service’s rules. Uninstalling the App does not normally cancel a subscription. For entitlement restoration, payment failures, refund status, or order issues, first use the applicable service’s order-management and support channels.

You may not obtain or use paid features through client modification, fabricated purchase status, sharing restricted entitlements, payment-bypass methods, or any other unauthorized means. To the extent allowed by law, we may limit or terminate entitlements associated with suspected abuse, fraud, or violations of these Terms.

7. Data, Backups, and Security

Projects, settings, recordings, exported archives, media, stream keys, and persistent authorization state are stored only on your device or in a location you choose and are not backed up to an App server. Limited authorization codes and tokens may be processed transiently by the stateless authorization relay described above. You are responsible for backing up important projects, safeguarding stream keys and platform credentials, and checking whether a project or exported file contains information that should not be disclosed before sharing it.

App updates, Android restrictions, insufficient storage, device failure, revoked permissions, third-party platform-rule changes, network interruption, or user error may cause a feature to be unavailable, a recording to fail, a transmission to stop, or data to be lost. To the maximum extent permitted by law, you bear the risk of loss of data that you have not backed up.

See the Mestrio Studio Privacy Policy for information about personal-data processing. Before using camera, microphone, screen-capture, network, or third-party-authorization features, read and understand the notices presented by Android and the applicable third party.

8. Feedback and Updates

You may send suggestions, bug reports, or other feedback to robinxdroid@gmail.com. Unless we agree otherwise in writing, you grant us a worldwide, perpetual, irrevocable, transferable, sublicensable, royalty-free license to use, copy, modify, improve, publish, and distribute that feedback without compensation or confidentiality obligations. Do not include unnecessary personal information, passwords, tokens, or stream keys in feedback.

The App may prompt for or require updates to fix defects, improve security, support system changes, or adjust features. If you decline a required update, some or all features may not operate properly.

9. Disclaimers

THE APP IS PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE DISCLAIM ALL EXPRESS, IMPLIED, AND STATUTORY WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, CONTINUED AVAILABILITY, SECURITY, ACCURACY, ERROR-FREE OPERATION, VIRUS-FREE OPERATION, UNINTERRUPTED OPERATION, AND COMPATIBILITY WITH THIRD PARTIES.

In particular, we do not guarantee that:

Nothing in these Terms excludes or limits consumer rights that cannot legally be excluded or limited.

10. Limitation of Liability and Indemnity

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, PUNITIVE, EXEMPLARY, OR CONSEQUENTIAL DAMAGES, INCLUDING LOSS OF PROFITS, REVENUE, GOODWILL, DATA, CONTENT, BUSINESS OPPORTUNITY, OR SUBSTITUTE SERVICES, ARISING OUT OF OR RELATING TO THE APP, UNDER ANY THEORY OF LIABILITY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF THOSE DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE APP WILL NOT EXCEED THE GREATER OF: (A) THE AMOUNT YOU ACTUALLY PAID TO US FOR THE APP IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO LIABILITY; OR (B) CNY 100.

To the extent permitted by law, you will indemnify and hold us harmless from claims, losses, penalties, liabilities, and expenses (including reasonable legal fees) arising from Your Content, unlawful use of the App, breach of these Terms, infringement of third-party rights, incorrect configuration of streaming destinations, or failure to safeguard credentials.

11. Suspension and Termination

You may stop using the App at any time and delete local data or uninstall it. To the extent permitted by law, we may suspend, limit, or terminate any feature for maintenance, security, third-party requirements, legal compliance, suspected unlawful activity, abuse, rights infringement, or breach of these Terms.

When these Terms terminate, your license to use the App ends. Provisions concerning intellectual property, disclaimers, limitations of liability, indemnity, dispute resolution, and provisions that by nature should survive will remain in effect. Termination does not affect rights, duties, or liabilities that arose before termination.

12. Changes to These Terms

We may update these Terms within a reasonable scope. For material changes, we will provide notice through an in-app notice, an updated document, or another reasonable method, and show the new effective date at the top. Your continued use after the effective date means that you accept the updated Terms. If you do not agree, stop using the App.

13. Governing Law and Disputes

Unless mandatory law provides otherwise, the formation, validity, interpretation, performance, and dispute resolution of these Terms are governed by the laws of mainland China, excluding the laws of the Hong Kong Special Administrative Region, the Macao Special Administrative Region, and Taiwan. The parties will first attempt to resolve disputes through good-faith consultation. If consultation fails, either party may bring an action before a court with jurisdiction.

If you use the App from another country or region, you are responsible for ensuring that your use complies with local law. Some jurisdictions do not allow the exclusion of certain warranties or limitation of certain liability; in those jurisdictions, the limitations above apply only to the extent allowed by law.

14. Other Terms

These Terms and the Mestrio Studio Privacy Policy are the entire agreement between you and us about use of the App and supersede prior oral or written agreements about that subject. If any provision is held invalid or unenforceable, the remaining provisions remain effective. Our failure to enforce a right is not a waiver of that right.
