Privacy Policy

Overview

This Privacy Policy applies to the Gemini Watermark Remover website (gemini-watermarkremover.org) and the Gemini Watermark Remover Chrome browser extension (collectively, "the Service").

The Service is operated as a free, open-source tool. We are deeply committed to user privacy. Our core design principle is local-first processing: your images are never sent to any server.

Information We Do Not Collect

The following data is never collected, transmitted, or stored by the Service:

Data Type	Collected?	Notes
Image files	Never	All image processing runs locally in your browser. No image data leaves your device.
Personal identifiers	Never	No name, email, IP address, or device ID is collected.
Browsing history	Never	The extension only activates on gemini.google.com and aistudio.google.com.
Usage analytics	Never	No telemetry, event tracking, or analytics SDK is included.
Crash reports	Never	No error reporting service is integrated.

Information We Do Store Locally

The Chrome extension stores exactly one piece of data on your device using the Chrome Storage API (chrome.storage.local):

This data is stored solely to remember your preference between browser sessions. You can clear it at any time by removing the extension or clearing Chrome's extension storage via chrome://settings/cookies.

How Image Processing Works

When you download an image on gemini.google.com or aistudio.google.com, the extension intercepts the image data entirely within your browser using the standard Fetch API.

The watermark removal algorithm (Reverse Alpha Blending) runs inside a JavaScript context on your local machine. The cleaned image is returned directly to your browser's download handler. At no point does any image data touch an external network connection or server.

The algorithm is open source and fully auditable at github.com/GargantuaX/gemini-watermark-remover.

Extension Permissions

The extension requests the following Chrome permissions and uses them exclusively as described:

• storage Used solely to save your enabled/disabled preference locally on your device via chrome.storage.local. No personal data is stored.
• activeTab Used to communicate the enable/disable toggle state to the currently active Gemini or AI Studio tab without requiring a full page reload. No tab content or URLs are read or recorded.
• host: gemini.google.com Required to inject the content script that intercepts image download requests on this page and applies watermark removal locally.
• host: aistudio.google.com Required to inject the content script that intercepts image download requests on this page and applies watermark removal locally.

Website Analytics

The website gemini-watermarkremover.org does not use any third-party analytics service (e.g., Google Analytics, Mixpanel, or similar).

Standard web server access logs (IP address, browser user agent, requested URL, timestamp) may be retained by our hosting provider for up to 30 days for the purposes of security monitoring and abuse prevention. These logs are not used for advertising or profiling and are not shared with third parties.

Third-Party Services

We do not integrate any advertising networks, affiliate tracking, or data broker services into the extension or website.

The extension is distributed via the Chrome Web Store, which is operated by Google. Google's own privacy policy governs any data collected through the Chrome Web Store platform and is not controlled by us.

Children's Privacy

The Service is not directed at children under the age of 13. We do not knowingly collect any personal information from children. Because we collect no personal data from any user, no special handling for children's data is required.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last updated" date at the top of this page. We encourage you to review this page periodically.

Because we collect no personal data, changes to this policy will not materially affect your privacy. Significant changes that do affect data handling will be announced on the website's homepage.
