Why InboxBriefs only has read-only access to Gmail

Connecting your inbox to a third-party service deserves caution. Here, plainly, is what InboxBriefs can and can't do with your Gmail.

June 6, 20264 min read

When you connect Gmail to InboxBriefs, you grant access through OAuth, Google's official way to authorize a third-party app. The key point is the scope requested: InboxBriefs asks only for gmail.readonly. That single scope determines, at the level of Google's own infrastructure, everything the app is able to do.

Read-only, guaranteed by Google, not by our promise

The distinction matters: it's not that InboxBriefs “chooses not to” change your emails. It's that Google doesn't give it the ability to. With the gmail.readonly scope, Google's servers reject any attempt to send, delete, archive or modify. Even if our code tried, it doesn't, the API would return a permission error.

Your access tokens are encrypted at rest

OAuth authorization takes the form of access tokens. These tokens are never stored in plain text: they're encrypted at the application level with AES-256-GCM before being saved. In practice, even direct access to the database would reveal only ciphertext, useless without the encryption key, which lives outside the database.

The same AES-256-GCM encryption applies to the generated summaries, the details of each analyzed email and the messages exchanged with the chatbot. Nothing sensitive is readable in plain text in the database.

We don't keep your emails

InboxBriefs reads the emails needed to produce a summary, then keeps the summary, not the full content of your inbox, permanently. Your inbox stays the source of truth; our data is just an analysis layer on top, kept to the strict minimum.

You can revoke everything in one move

Disconnecting a Gmail account from your dashboard immediately revokes our access on Google's side, the token becomes unusable that very instant. And if you delete your InboxBriefs account, all associated data is erased permanently and in cascade within minutes.
