All Inboxes for Gmail: Privacy Policy
Last updated October 29, 2026
In short: All Inboxes for Gmail shows mail from the Gmail accounts you connect in one list, inside Gmail in your browser. Your mail goes only between Google and your own browser. The developer has no server and never sees, collects, stores, sells or shares your data.
What the extension accesses
Only for the Google accounts you choose to connect, and only so it can show and manage your inbox and the results of your searches:
- Your Gmail messages: for the list, the sender, recipients, subject, date, a short preview, labels (such as Inbox, Unread, Starred and Gmail's tabs) and the names of attached files. When you open an email, its full text and pictures, and any attached file you click. All of it is read through the Gmail API.
- Your Google profile: your email address, name and profile picture, used to label each account.
- Your Gmail sending settings: the signature, sending name and sending address set in an account's Gmail settings, read when you pick that account in a compose window's From line (or when an email moves into that account's Gmail).
- Sign-in keys: the short-lived access keys Google gives the extension when you sign in.
It does not read your contacts, calendar, files or any other Google data, and it does not track the websites you visit.
What it does with your mail
Only what you ask for: showing your inbox, the emails that match when you search (through all your mail, as Gmail's own search does), and the emails you open, and archiving, starring, marking read or unread, or moving to Trash the conversations you choose. Opening an email marks it read, as Gmail does. It sends an email only when you click Send on one you wrote (see below), and it can't permanently delete your mail (the only thing it throws away is Gmail's leftover draft of an email it has just sent for you).
An email you open is shown in a sealed-off frame where nothing in it can run. Like most email apps, pictures in it load from wherever the sender put them, so the sender's server can see that the email was opened (and your internet address), just as when you open it in Gmail's mobile app with pictures on. In Settings you can choose to be asked first.
If you click Unsubscribe next to a sender and confirm, the extension uses the unsubscribe address that sender put in the email: it sends that address a one-click "unsubscribe" request, or opens a ready-to-send unsubscribe email in that account's Gmail, or opens the sender's unsubscribe page in a new tab. Nothing else about you is sent.
When you're writing an email in Gmail and pick another of your connected accounts in the From line, the extension reads that account's signature and sending address from its Gmail settings and puts the signature in the email. When you click Send, it sends the email (recipients, subject, text and signature) from that account through the Gmail API, after a few seconds in which you can undo it. While you write, Gmail keeps the email as a draft in the account of the Gmail tab you're in, as it does for any email you write there; the extension throws that draft away once the email has gone (if the tab was closed meanwhile, that account's Gmail tells you next time, so you can delete it). (A school or work account's administrator may be able to keep a copy of drafts even after they're thrown away.) The extension also remembers, in your browser, which account each such draft goes out from (until you pick the tab's account again, or at most 30 days), and whether it was already sent, so a draft opened again goes out from the right account and isn't sent twice by mistake. In Settings you can choose the older way instead: the email moves into the other account's own Gmail compose window in your browser, and Gmail sends it from there (the extension then reads that account's signature too, in case Gmail doesn't add it).
Where your data goes
- All requests go directly from your browser to Google (gmail.googleapis.com, www.googleapis.com, oauth2.googleapis.com and accounts.google.com, plus profile pictures from googleusercontent.com). Nothing is sent to the developer or to anyone else (apart from pictures in an email you open, an unsubscribe request you ask for, and the emails you send, all described above).
- There are no analytics, ads, trackers or third-party services.
- Your data is never sold, never transferred to others, and never used for advertising, credit decisions or anything unrelated to showing and managing your mail.
What is saved on your computer
- Kept only in your browser's memory and erased when you close the browser: sign-in keys and a short list of recent conversations (sender, subject, preview, date, labels, attachment names), so the list opens quickly; and an email being moved into another account's Gmail window, until it's filled in (at most 15 minutes). The text of an email you open is only on screen; it isn't saved.
- Saved in your browser: your list of connected accounts (address, the name, tag and color you chose, profile picture link), your settings, unread counts, which account each draft you picked another account for goes out from and whether it was sent (at most 30 days), and, if a Gmail tab was closed or reloaded while one of these emails was going out, that email's subject and how it went, so that account's Gmail can tell you its draft is still there (until you next open that account's Gmail, at most a week).
None of this leaves your computer except to Google, as described above.
Google API data
The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
The use of information received from Google Workspace scopes (Gmail) will adhere to the Google User Data Policy, including the Limited Use requirements, and to the Google API Services User Data Policy.
Nobody reads your email. The developer never has access to it, and the extension only shows it to you.
Removing your data
- In the extension's Settings, click Remove next to an account. That deletes what's saved for it and, if the account is signed in at the time, asks Google to cancel the extension's access.
- Removing the extension from your browser deletes everything it saved.
- You can also cancel its access at any time at myaccount.google.com/permissions.
Children
The extension isn't directed at children under 13 and doesn't knowingly collect anyone's personal information. It collects none at all.
Changes and contact
