Brand relationship
How Stay Summers relates to Inter Green.
This removes ambiguity for platform reviewers: Stay Summers is the product brand, while Inter Green is the registered legal operator.
Product brand
Stay Summers is the public brand used for early-stage games, SaaS tools and learning products. It is not a separate legal entity.
Platform independence
Stay Summers and Inter Green are independent businesses and are not affiliated with Meta, Facebook, Instagram or WhatsApp.
Business activities
What the company operates.
The website should show a real business purpose, not just a single app page created for verification.
Software development
Design, build and operate web applications, social game interfaces, customer support tools and internal product infrastructure.
Game publishing
Operate skill-based game experiences such as Cờ Tướng Thách Đấu with virtual progression, ranking and fair-play controls.
SaaS operations
Develop fanpage management and chat workflow products for authorized business users and page teams.
Support and privacy
Maintain public support, privacy, legal and security channels under the same domain to keep user requests traceable.
Data minimization
Collect only product data needed for login, gameplay, page operations, support, safety, analytics and compliance.
Accountability
Keep admin access, domain ownership, app ownership and product contact points under the same verified business profile.
Meta submission profile
Business details to enter consistently.
Use these values when filling Meta Business Portfolio, Facebook Page, App Dashboard and verification forms.

Professional verification is mostly about consistency. Every public product should point back to this operator profile.

Review evidence
Compliance pages prepare the documents, screencast steps and safety statements needed for BM verification and game app review.
