Privacy Policy for Gmail Multi Account Notifier
Last updated: November 12, 2026
Gmail Multi Account Notifier is a Chrome extension that checks configured Gmail accounts for unread message counts and sign-in status.
Data the extension stores
The extension stores the following data locally in Chrome extension storage:
- Gmail email addresses entered by the user
- Optional account display names entered by the user
- Gmail account slot numbers entered by the user
- An optional Gmail label per account, entered by the user, to watch instead of the inbox
- A colour chosen per account, and the order the accounts are listed in
- Per-account mute and silent preferences
- Optional quiet-hours start and end times, and a notification pause time
- Last known unread counts
- Last known account status, such as available, signed out, or wrong account
- Extension settings such as polling interval and notification preference
- The user's acknowledgement of the extension's data-use disclosure
- The message-snippet setting, and whether the user has agreed to its terms
The Gmail Atom feed requested by the extension may contain message summary metadata: each unread message’s sender, subject, time and a short snippet. In the background the extension uses only the account identity, unread count, and sign-in status. It never reads full message bodies.
Message reader. When the user expands an account in the extension’s popup, the extension reads the sender name and address, subject and time of that account’s unread messages from the same feed and displays them in the popup. This happens only when the user expands an account. The values are held in memory while the popup is open, are discarded when it closes, and are never written to extension storage or transmitted anywhere.
Message snippets. A snippet is the opening text of a message as provided by the feed. Snippets are never read unless the user turns on the optional setting “Show message snippets in the popup” and separately ticks an explicit agreement describing how snippets are handled. Both are off by default. With the setting on, snippets are read only when the user expands an account, are shown in the popup’s message reader, are held in memory while the popup is open, and are never written to storage, synced, or transmitted. Turning the setting off stops snippets being read immediately and clears the agreement, so turning it on again requires agreeing again.
Notification preview. If the user turns on the optional setting “Show the sender and subject in notifications”, the extension additionally reads the sender name and subject of the newest message and passes them to the Chrome notification. These values are held only for the moment the notification is created and are never written to extension storage or transmitted anywhere. The setting is off until the user turns it on.
How data is used
The extension uses this data only to:
- Display unread Gmail counts in the extension popup
- Show the toolbar badge count
- Open the selected Gmail inbox
- Show the sender, subject and time of unread messages (and their snippets, if the user has turned snippets on and agreed to it) in the popup when the user expands an account
- Notify the user when unread mail appears
- Show, in red in the popup and on the toolbar badge, when a configured account is signed out or appears to be the wrong account
Syncing between devices
By default every setting stays on the computer where it was entered, and nothing leaves that machine.
The Options page offers an optional “Sync settings across devices” setting, which is off until the user turns it on. While it is on, the extension writes its settings to Chrome’s own sync storage: the configured email addresses, account names, colours, labels, slot numbers, per-account mute and silent preferences, account order, and the general preferences. Chrome mirrors that data through the user’s own Google account to their other signed-in Chrome profiles.
Unread counts, account status, the notification pause, the data-use consent flag, the message-snippet setting and its agreement, and message content of any kind are never synced. Nothing is sent to the developer, and the developer cannot read synced data. Turning the setting off stops further syncing; data already in Chrome’s sync storage can be cleared by signing out of Chrome sync or removing the extension.
The user can also copy their settings to the clipboard from the Options page and paste them into another installation. That transfer happens entirely through the clipboard, under the user’s control, and involves no server.
Data sharing
The extension does not sell, share, transfer, or disclose user data to third parties. It does not use analytics or advertising. The optional device sync described above moves data only between the user’s own Chrome profiles, through their own Google account, and never to the developer.
The extension never asks for, receives, or stores a Google password. Its “Sign in another account” button only opens Google’s own sign-in page in an ordinary browser tab, and the extension learns of the new account afterwards in the same way as “Detect accounts”.
Remote servers
The extension does not send user data to any server owned by the developer.
The extension requests Gmail unread count information directly from
https://mail.google.com/mail/ using the user's existing signed-in
Chrome/Gmail session.
Remote code
The extension does not load or execute remotely hosted code.
Limited Use
The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
Data retention
Data remains in Chrome extension storage until the user edits the settings, clears extension data, or uninstalls the extension.
