Favorites and History Guide
Client-Side Storage Overview
SlotVNPG Demo Lab does not use user registration, passwords, or persistent cloud member databases. Instead, your personal collection of bookmarked slot demos and recently played titles relies directly on your web browser's localStorage.
This mechanism guarantees that you can quickly return to preferred demonstration cards on this device without having to create an account or provide any personal credentials to our server.
How localStorage Operates on This Site
When you mark a demonstration as a favorite or launch a title from its dedicated detail page, the game's unique identifier is saved strictly into your browser's local key-value store. Our platform specifically utilizes localStorage rather than IndexedDB or session cookies for these lists.
Because this storage is tied to the exact browser and device you are currently operating, your preferences do not synchronize automatically across different phones, tablets, or desktop computers. If you switch to another browser, you will begin with an empty list.
Network Transmission and Server Rendering
SlotVNPG operates as a server-rendered platform to deliver fast, structured game cards. When you open your favorites or history overview, your browser sends the stored numeric or text game identifiers to our application programming interface (API).
This transmission allows our server to look up the relevant visual metadata, official titles, and provider tags to construct the view. These transmitted identifiers are processed transiently to build the interface and are not compiled into a permanent, server-side personal user profile.
Clearing and Resetting Your Saved Preferences
Your interface language selection, bookmarked demos, and recent play records remain in your browser until manually removed or purged by system maintenance tools.
If you clear your browser cookies and site data, use incognito or private browsing modes, or reset your web browser cache, your localStorage items for slotvnpg.com will be removed immediately. Once purged, these records cannot be restored by our team since we keep no backup copies on remote servers.
Data Privacy and Local Limitations
While our local-first preference model prevents the creation of centralized user profiles on our backend, it does not imply absolute network isolation. Web hosting infrastructure and third-party game demonstration engines still receive standard request headers, such as your IP address and user-agent string.
We recommend treating your local favorites list as a convenient browsing aid rather than an archival database. You are always free to clear your browsing data at any time via your browser settings menu.
