Van Gogh Ad Swap · Last updated 25 August 2026

Van Gogh Ad Swap is a Chrome extension that replaces advertisements on web pages with open-access Vincent van Gogh paintings bundled in the extension. This page describes what the extension does with information on your device.

Data we do not collect

The extension does not have a backend, analytics, advertising identifier, or account system. We do not collect, sell, share, or transmit:

• Your name, email, or other identity
• Browsing history, URLs, or page content
• Cookies, form fields, or authentication tokens
• Location, financial, or health information

Paintings are stored inside the extension package. They are not downloaded from our servers when a page loads, and we never upload a copy of the page you are viewing.

What is stored on your computer

The only setting the extension saves is whether replacement is turned on or off. That boolean is written with Chrome’s storage.sync API so the preference can follow your Chrome profile if you have sync enabled. Chrome stores that value in your browser profile. The developers of Van Gogh Ad Swap cannot read it.

Why the extension runs on many websites

Advertisements appear on websites the extension cannot list in advance. A content script therefore runs on pages you visit over HTTP and HTTPS, looks for common ad slots in the page, and—when replacement is on—substitutes a local image. That work happens entirely in your browser. The script does not send page HTML, screenshots, or URLs to us or to any third party.

Permissions

• storage — saves the on/off preference described above.
• Access to sites you visit — required so the content script can find ad slots and replace them with bundled artwork. No remote code is loaded.

Children

The extension is not directed at children and does not knowingly collect personal information from anyone, including children.

Changes

If this policy changes, the date at the top of the page will be updated. Continued use of the extension after a change means you accept the revised policy.
