Dark Mode for Every Finance Site
Guides for each service below — private, open-source, and nothing sent anywhere.
Why Banking Sites Need Dark Mode
Banking portals are almost universally bright white — fine at noon, glaring at 11 PM when you're reviewing a statement. Since finance sessions tend to be short but frequent, a scheduled dark mode means you never have to think about it.
Private by Design — Important for Banking
Turn Off the Lights does not read, collect, or transmit your browsing data — essential on financial sites. Everything happens locally in your browser, and the code is open-source on GitHub so you can verify exactly what it does before you install it on pages that matter.
Open Source, Private, and Free — Always
Turn Off the Lights collects no personal data, displays no advertising, and charges nothing. The extension is fully open-source under the GNU General Public License Version 2 (GPLv2), with its complete source code available on GitHub for anyone to inspect. It has been in continuous development since 2009 and remains one of the most trusted browser extensions available, with millions of active users across all major browsers. Stefan Van Damme is the solo developer and has maintained the extension with monthly updates for over 15 years.
