JKLM Profile+ ("the extension") is a browser extension that adds custom profiles, a friends system, and real-time private messaging to jklm.fun . This policy explains what data the extension collects, how it is used, and where it is stored.
The extension collects and stores the following categories of data:
| Data | Purpose |
|---|---|
| Profile info (display name, avatar image, banner image, status, "About" description) | Displayed to other players on your profile card |
| Randomly generated user ID | Anonymous identifier used to add friends and route messages — not linked to any real-world identity |
| Friends list, friend requests, blocked users list | Powers the friends and blocking features |
| Direct messages and group chat messages | Enables real-time private messaging between users |
| Presence / online status, typing indicators, read receipts | Shown to your contacts while a conversation is open |
| Pinned conversations, unread message counts, group cache | Local convenience data for the chat UI |
The extension does not collect: real names, physical addresses, government ID numbers, health information, financial or payment information, passwords, or your general browsing history outside of jklm.fun.
Your profile settings, friends list, blocked list,
and cached chat history are stored locally in your browser
using the chrome.storage.local API.
This data stays on your device and is not accessible
to other websites.
To enable real-time messaging, the extension connects
to a companion server over a secure WebSocket
(wss://) connection.
Through this connection:
The server does not load or execute any remote code in your browser — it only relays chat data. No message content, profile data, or identifiers are sold or shared with third parties.
We do not sell or transfer user data to third parties. Data is used only to provide the extension's features (profiles, friends, and messaging) and is not used for advertising, credit assessment, lending purposes, or any purpose unrelated to the extension's function.
Locally stored data persists until you remove the extension or clear its storage via your browser's extension settings. To delete your account data from the server, contact us using the information below.
Avatars and banners you upload are stored/displayed as provided. If you use an externally hosted image URL, that image is loaded from its original host, which is subject to that host's own privacy practices.
The extension is not directed at children and does not knowingly collect data from children.
This policy may be updated from time to time. Continued use of the extension after changes are posted constitutes acceptance of the updated policy.
Questions about this policy or requests to delete your data can be sent via our Discord server .
