Privacy Policy

Last updated: 2026-11-12

Dark Mode for Gmail is a Chrome extension that makes Gmail on the web dark. This policy describes what it can access and what it does with it. It is short because the extension does very little.

The extension collects nothing

There is no account, no server, no analytics and no advertising. The extension makes no network requests of its own and sends nothing anywhere.

What it can access, and why

Gmail pages at mail.google.com, and no other site. It loads a style sheet that darkens the page and adds a class to the page that switches it on. To tell whether Gmail is already dark, it reads the page’s text colour. It passes only that yes or no, with the on or off setting, to its own toolbar icon, which then explains in that tab why it is paused. To keep photos in their real colours, it checks whether a background picture has any text over it, without keeping that text. It never stores or sends your email, contacts or anything you type.
Storage, to remember one setting: whether the dark mode is on or off.
The toolbar menu, to add two tip links to the icon’s right-click menu. Choosing one opens Buy Me a Coffee or PayPal in a new tab.

The things that happen outside the extension

Chrome sync. The on or off setting is saved with Chrome’s sync storage. If you sign in to Chrome with sync turned on, Google keeps that one setting with your Google account.
The Chrome Web Store. Installing and updating the extension is a transaction between your browser and Google, with its own privacy policy.
A tip, if you choose to leave one. Buy Me a Coffee and PayPal handle the payment under their own privacy policies.
An email you choose to send. It reaches the support mailbox and is used only to answer you.

Deleting your data

Removing the extension deletes its setting from your browser.

Changes

If this policy changes, the date at the top changes with it, and the history of this file is public in the repository.
