When you deploy a Google Apps Script as a web app, Google automatically displays a banner at the top or bottom of the page that reads, " This application was created by a Google Apps Script user.

" This is a mandatory security feature intended to inform users that the application is not an official Google product. Google Issue Tracker

While there is no native "off switch" in the Apps Script settings to remove this disclaimer for all users, several workarounds and specific deployment scenarios can hide or eliminate it. Native Scenarios Where the Banner is Hidden

In certain environments, Google naturally hides the banner because the "untrusted" risk is minimized: Internal Workspace Domain : If the script owner and the user are in the same Google Workspace domain, the banner often does not appear. Google Sites Embedding : Embedding your web app within a Google Site typically prevents the banner from showing to visitors. Google Workspace Add-ons : Converting your script into a verified Google Workspace Add-on

(published to the Marketplace) removes the web app banner, as the app has undergone a review process. Technical Workarounds

If the native scenarios above don't fit your needs, developers often use these technical methods to bypass the banner: Self-Hosted Iframe : Instead of sending users directly to the script.google.com

URL, you can host a simple HTML page on your own domain (e.g., via GitHub Pages) and embed the Apps Script URL inside an

. This "wraps" the app in your own branding, though it may require specific X-Frame-Options settings in your script to allow embedding. Browser Extensions (Client-Side)

: For internal tools where you control the browser, you can use extensions like GAS WebApp Warning Remover (Firefox) or Custom JavaScript for Websites (Chrome) to inject CSS that sets display: none on the banner's HTML ID (usually GCP Project Association : Associating your Apps Script with a standard Google Cloud (GCP) project

and completing the OAuth verification process can sometimes help manage how warnings are displayed, though it is primarily for removing the "App not verified" screen rather than the footer banner.

The message "This application was created by a Google Apps Script user" is a mandatory security banner displayed by Google on web apps created with Google Apps Script. It is designed to alert users that the application was not created by Google and may request sensitive permissions.

While there is no single button to "turn off" this banner for free consumer accounts, there are several methods to remove or bypass it depending on your environment. 1. Embed the Web App in a Google Site

The most reliable "no-cost" way to remove the banner for external users is to embed your Apps Script web app into a Google Site.

When a web app is viewed through an iframe on a Google Site, Google typically suppresses the author warning banner.

Requirement: Ensure your web app deployment is set to "Anyone" or "Anyone with a Google Account" and that the site itself is shared with your target audience. 2. Use a Google Workspace Account (Internal Use)

If you are developing for an organization, the banner is automatically hidden for users within the same domain.

If you own a Google Workspace (Business, Enterprise, or Education) account and deploy the script so only "People within [Your Domain]" can access it, they will not see the banner.

The warning only appears when the script is accessed by someone outside your Workspace organization or by a consumer (Gmail) account user. 3. Complete Google Cloud Project Verification

For public-facing applications that cannot be restricted to a Workspace domain, the official way to remove security warnings is through Google Cloud verification.

Process: You must associate your Apps Script with a standard Google Cloud Platform (GCP) project instead of the default "default" project.

Outcome: Once your project is verified as a "Verified Publisher" by Google, the banner and "unverified app" warnings will disappear for all users. Note that this process can take several weeks and may require a security audit if you use restricted data scopes. 4. Technical Workarounds (For Personal Viewing)

If you only need to hide the banner for yourself (e.g., on a public display or TV), you can use browser-based tools:

Custom JavaScript Extensions: Extensions like "Custom JavaScript for websites" can be used to inject code that sets the CSS of the banner to display: none;.

GitHub Solutions: Community-made plugins such as apps-script-remove-warning on GitHub are designed to auto-hide these elements in your browser.

Note: These methods only hide the banner for you and anyone else who has the extension installed; they do not remove it for the general public.

The "This application was created by a Google Apps Script user" banner is a mandatory security feature. Google includes this footer on standalone web apps to notify users that the application was built by an independent developer, not by Google itself.

While there is no single "disable" button for this banner, you can bypass or remove it using several methods depending on your environment. 1. Embed the Script in a Website

The most reliable way to hide the banner for external users is to embed your Apps Script Web App within another webpage.

Method: Use an
