Who's Using This Website is a Chrome extension that lets users share that they are currently using a website with other users in the same channel. This Privacy Policy explains what information the extension collects, how it is used, and how it is stored.
The extension collects only the information needed to provide its core feature:
Display username: The username a user enters when choosing to share their presence.
Channel name: The channel string a user enters to decide who can see their presence.
Website information: The website origin and hostname for the site the user explicitly chooses to share.
Presence timestamps: Timestamps used to show whether the user is currently active and to expire old presence records.
Anonymous Firebase identifier: Firebase creates an anonymous authentication ID so each extension user can update only their own presence record.
The extension does not collect:
Passwords, credentials, security questions, or PINs.
Health, financial, or payment information.
Emails, text messages, chats, or personal communications.
GPS location or precise physical location.
Keystrokes, mouse movements, scroll behavior, clicks, or general user activity.
Page content such as text, images, videos, sounds, or hyperlinks.
A complete browsing history. The extension only processes the active website when the user opens the extension and chooses to share.
Collected information is used only to:
Show other users in the same channel who is currently using the same website.
Refresh the user's presence while they remain on the shared website.
Remove or expire presence records when the user stops sharing or the extension can no longer refresh the active presence record.
Remember the user's last-used username and channel locally in the browser.
Presence information is visible only to other extension users who are on the same website and enter the same channel string. We do not sell, rent, or trade user data. We do not use collected data for advertising or user profiling.
Presence data is stored in Firebase Realtime Database. Firebase Anonymous Authentication is used to protect database writes so users can update only their own presence record. Some settings, such as the user's last-used username and channel, are stored locally in the user's browser using Chrome extension storage.
Presence records are temporary. The extension refreshes active records and sets short expiration timestamps so stale records stop appearing automatically. A user's active presence record is removed when they stop sharing. If the extension can no longer refresh the record, the record stops appearing after its short expiration time.
Users choose when to share their presence by opening the extension, entering a username and channel, and clicking Share. Users can stop sharing from the extension popup. Users can also remove locally stored extension data by removing the extension from Chrome or clearing the extension's site data.
The extension does not load or execute remote code. All extension JavaScript is packaged with the extension. Firebase is used only as a backend service for authentication and database requests.
The extension is not intended to collect information from children under 13. Users should not enter personal information as their display username or channel name.
This Privacy Policy may be updated if the extension's functionality or data practices change. The updated policy will be posted at the same location where this policy is hosted.
