Is Checker for Gmail™ safe to install?

What data it declares

The developer declares that it does not collect or use your data.

The developer also certifies that your data is not sold to third parties outside approved uses, not used for purposes unrelated to the extension's core function, and not used to decide creditworthiness or lending.

The listing links to a privacy policy.

This is the developer's own declaration in the Chrome Web Store. We cannot check it against what the extension does.

What Chrome asks you to allow

When you add it, Chrome asks you to allow it to:

• Display notifications

Derived from the manifest by Chrome's documented rules; the dialog's exact wording depends on your Chrome version and language. Chrome asks again if an update requests more.

What it can reach

No site access is declared in the manifest, so it cannot read the pages you open on its own.

Worth knowing

• Sign you in with a Google account identity

Routine for an extension

• Schedule work to run later alarms
• Show you notifications notifications
• Run work in a hidden page offscreen
• Open a panel beside the page sidePanel
• Store data in your browser storage

What it may ask for later

Not granted when you add it: Chrome asks you the moment the extension requests one of these, and you can refuse.

• https://mail.google.com/* only mail.google.com
• https://graph.microsoft.com/* only graph.microsoft.com
• https://login.microsoftonline.com/* only login.microsoftonline.com

What the store shows

The store shows none of its badges on this listing. Most listings carry none.

Has it asked for more over time?

This is the question a permission list on its own cannot answer. An extension that shipped narrow and widened later is a different proposition from one that always asked for the same thing.

The permissions this extension requests have not changed since we started watching it.
